180 A bstracts

Woodroffe, G. E. (1957). On the identity of the British Macrolopihus Fieber (Hem., Miridae), with a key to the European species. Entomologist, 90, 125-127.

I. rubi sp.n. is described from bramble in Britain, where it was formerly confused with M. subilis on Stschys sylvatica and was later misidentified as M. costalis. Stichel's key to the European species is modified to accommodate it.

3. PARASITES

Barfoot, S. D. (1957). Oviposition of Ptychomyia selecta Meig. (Dipt., Tachinidae). Ent. Mon. Mag. 93, 95.

A description is given of females of the Tachinid fly Ptychomyia selecta depositing eggs on the sawfly larvae Nematus ribesii.

Copland, W. 0. (1956). Notes on the food and parasites of pike (Esox lucius) in Loch Lomond. Glasgow Nat. 17, 230-235.

Based on the contents of 102 stomachs. Pike were infested with two species of parasitic helminth, the pseudophyllidean cestode Triaenophorus nodulosus and the acanthocephalan A canthocephalus lucii

Crooke, M. (1956). Host of the overwintering generation of Trichogramma evanescens Westw. (Hym., Trichogrammatidae). Ent. Mon. Mag. 92, 368.

The pine-looper caterpillar Bupalus piniarius is recorded as the host of the overwintering generation of Trichograimma evanescets.

fasciatus, are recorded from mice on the island.

Gotto, R. V. (1956). The occurrence of a doropygid copepod in a new ascidian host. Irish Nat. J. 12, 110.

Doropygus psyllus on Ascidia conchilega.

Gradwell, G. R. (1957). Hosts of three species of Eulophus Geoffroy (Hym., Chal- cidoidea), one new to science and another new to Britain. Ent. Mon. Mag. 93, 140-142.

Descriptions are given of Eulophus igribasis sp.n., E. larvarum and E. opacula (Th.), the last being new to Britain. Host records are given.

Michel, J. F. (1957). Husk in adult cattle. Agriculture, 64, 224-228. Control of the disease must be based on acquired resistance to the lungworm parasite. The

ultimate source of infection is the dung of infected animals.

Moir, R. J. & Somers, M. (1956). A factor influencing the protozoal population in sheep. Nature, Lond. 178, 1472.

Concentration of ruminal Protozoa influenced by diet, but other factors may overshadow this. The manner in which the same diet is fed to sheep causes sharp divisions in protozoal counts. Suggests that feeding habits may be an important factor in determination of population level.

Noble, E. R. (1957). Seasonal variations in host-parasite relations between fish and their Protozoa. J. Mar. Biol. Ass. U.K. 36, 143-155.

The variation in protozoan parasite infection of three common marine fish; the intensity of infection may be related to the different feeding habits of the fish.

Food and food habits 181 Smit, F. G. A. M. (1956). Preliminary descriptions of two new European fleas.

Ent. Mon. Mag. 92, 296. Short descriptions of two new species of fleas, Ctenophthalmus bisoctodentatus occidentalis

and Hystrichopsylla talpae orientalis are given together with remarks on distribution.

Smith, K. G. V. (1957). Some Ichneumonid parasites and a Eulophid hyperparasite (Hym.) bred from egg-sacs of a spider. Ent. Mon. Mag. 93, 102.

Egg sacs of the spider Tetragnatha extensa were collected and four genera of Ichneumonid parasites emerged from them. In addition Pediobius spp. were recorded as parasitizing co- coons of these Ichneumons.

4. FOOD AND FOOD HABITS

Allen, A. A. (1957). Tachinus spp. selected as prey by Philonthus tenuicornis M. & R. (Col., Staphylinidae). Ent. Mon. Mag. 93, 94.

In a mixed lot of beetles enclosed in a glass tube, the rove-beetle Philonthus tenuicornis attacked and ate species of Tachinus.

at Kendal in October 1953.

saxatilis.

Brown, S. C. S. (1957). Argynnis lathonia (L.) (Lep., Nymphalidae) attacked by a lizard. Ent. Mon. Mag. 93, 36.

A specimen of the butterfly A rgynnis lathonia is described in which the wings are thought to have been damaged by a lizard.

Edwards, R. L. (1956). Dermestes frischii Kug. (Col., Dermestidae) attacking the shells of cuttle-fish. Ent. Mon. Mag. 92, 408.

Shipments of cuttle-fish shells were found to contain pupae of the beetle Dermestes frischii Kug. It is suggested that the adult beetles lay their eggs on the dead cuttle-fish laid out to dry in the sun, and that the larvae feed on the flesh, subsequently boring into the shell to pupate.

Gibb, J. & Hartley, P. H. T. (1957). Bird foods and feeding-habits as subjects for amateur research. Brit. Birds, 50, 278-291.
