191T1 ECONOMIC ZOOLOGY — ENTOMOLOGY. 667 



Destruction of wheat by wasps, F. W. Fbohawk {Entomologist, 50 (1917), 

 No. 649, pp. 132, 1S3, fig. 1). — Vespa vulgaris, a common wasp in England, is 

 said to feed upon and damage the heads of wheat in that country. 



The host of Ablerus clisiocampee, B. A, Pokteb (Ent. News, 28 (1911), No. 

 4, p. 1S6). — The author records the rearing of A. clisiocampee in some numbers 

 from the egg masses of the tent caterpillar, together with Telenomus colora- 

 densis, Tetrastichus malacosomce, and Ooencyrtus sp., of which T. malacosomce 

 was by far the most abundant. 



A new West Indian chalcid fly, A. A. Girault (Canad. Ent., 49 (1917), No. 

 10, pp. 356, 357). — Achrysocharella alMtibiw n. sp. is described from a single 

 female collected in St. Vincent. 



Notes on Perisierola emigrata, a parasite of the pink bollworm, A. BuscK 

 (Insecutor Inscitiw Menstruus, 5 (1917), No. 1-3, pp. 3-5). — These notes relate 

 to observations in Hawaii of the species described as new and previously re- 

 ferred to as Goniozus cellularis, the larva of which is an external parasite of 

 the full-grown pink bollworm. It was found to occur commonly in all the cotton 

 fields on the island of Oahu and in the Kona cotton district of Hawaii, and is at 

 present the only parasite of the pink bollworm of any importance. It is, how- 

 ever, by no means an effective check, and destroys only a small percentage of 

 the cotton pest. 



Notes on coccid-infesting Chalcidoidea, III, J. Watekston (Bui. Ent. Re- 

 search, 7 (1917), No. 4, pp. 311-325, figs. 7).— This continuation of the article 

 previously noted (E. S. R., 37, p. 467) includes descriptions of three new 

 species and one new variety from the West Coast of Africa. 



Two new species of Macrophya, S. A. Rohwer (Ent. News, 28 (1917), No. 

 6, pp. 264-266). 



The occurrence of the genus Monobaeus in North America, A. A. Giraitlt 

 (Ent. News, 28 (1917), No. S, p. 106). — A new species, Monobwus hegeli, is de- 

 scribed from a female specimen from Michigan. 



Notes on some parasites of sugar cane insects in Java, with descriptions 

 of new Hymenoptera Chalcidoidea, A. A. Giraxilt (Entomologist, 50 (1917), 

 No. 649, pp. 134-136). — Three parasites, probably of economic importance, are 

 here described as new, namely, Gonatocerus bifasciativentris reared from eggs 

 of a leafhopper embedded in the leaves of sugar cane ; Parachrysocharis javensis, 

 n. g. and n. sp., from Plata afflnis; and Cyrtogaster javensis, from lepidopterous 

 eggs. 



The hothouse milliped, E. N. Cory and F. H. O'Neill (Maryland Sta. Bui. 

 206 (1917), pp. 283-294, figs. 5).— Reports received at various times attributing 

 injuries to the hothouse milliped (Oxidus gracilis) and requests by florists and 

 gardeners for information regarding its economic status led to the hothouse 

 studies here reported. 



This myriapod, a species of tropical origin widely distributed in temperate 

 climates, is thought to have been introduced into the United States from 

 Europe. Its distribution in this country seems to include the States along the 

 Atlantic coast and as far west as the Mississippi Valley. 



It is rarely seen during the day, being nocturnal in its habits. There ap- 

 pears to be but one generation a year, although the date of the oviposition 

 period varies so much with individuals that specimens of all sizes may be 

 found at ahnost any time. 



The eggs are usually laid in the spring in masses, those counted containing 

 from 9 to 327 eggs, and the average cluster containing from 175 to 250 eggs. 

 The first eggs were observed on February 9, although the greatest number were 

 found during April and May. The depth to which they are placed in the soil
