 Genus Leucopis in the Anglo-Egyptian Sudan. — Ent. Mtlily. Mag., 

 London, Iviii, no. 694, 3rd Ser. viii, no. 87, March 1922, pp. 61-64. 



Leucopis sp., the various stages of which are described, was found 

 in 1914 feeding on Aphis sorghi, Theo., infesting dura [Sorghum 

 vulgar e) in the Anglo-Egyptian Sudan. The larvae of the Syrphid, 

 Syrphus aegyptius, Wd., and the Coccinellids, Coccinella vicina, Muls., 

 and C. undecimpunciata, L., also prey upon this species. In February 

 a species of Leucopis was also found attacking Aphis gossypii, Glov., 

 on cotton near Khartoum. The breeding of the species of Leucopis 

 attacking A. sorghi is apparently continuous, and the generations 

 overlap. Under laboratory conditions the average number of eggs laid 

 by each female was 34, but under natural conditions probably more are 

 laid. They are deposited singly and are attached horizontally to the 

 surface of the leaf close to the colonies of Aphids. On Sorghum they 

 are invariably found on the lower surface, but on cotton they occur on 

 the upper surface of the leaves. The eggs hatch in two days ; the 

 larval period lasts live and the pupal stage four, giving a total cycle 

 from egg to egg of 13 days. The Leucopis is parasitised by a Chalcid 

 not 5'et detemiined.

 Mag., London, Ivhi, no. 694, 3rd Ser. viii, no. 87, March 1922, p. 65. 



Carpophilus ligneus, Murr., is recorded from various localities in 

 Britain on dried Calif ornian plums, dried apples and jelly blocks, and 

 it is possible that this beetle may spread rapidly as a commercial pest. 



A key is given to the species of Carpophilus recorded by Fowler,

 with Descriptions of two new Species. — Proc. Ent. Soc. Washington, 

 D.C., xxiv, no. 2, February 1922, pp. 33-58, 1 plate. 



Phytophagous habits among Chalcids are considered to be of fairly 

 recent date, and this theory is supported by the fact that certain species 

 of Eurytomids are parasitic in their early stages and finish their develop- 

 ment as plant feeders. This adaptation was probably first forced upon 

 the parasite by premature exhaustion of the natural food supply due 

 to attacking a host which was insufficient in itself to furnish food for 

 complete development. 



A list is given compiled from the literature of the species of 

 Chalcidoidea said to be phytophagous, with exception of the fig insects. 



The new species described are the Eulophid, Rhicnopeltella eucalypti, 

 reared from galls on Eucalyptus globulus from New Zealand, and the 

 Eurytomid, Harmolita phyllostachitis , reared from young stems of 

 bamboo, Phyllostachys bambusoides, from Florida. 



Harmolita poaeola, n. n., is suggested for H. poae, Phillips & Emery 

 [R.A.E., A, vii, 470] (not Schlechtendal 1891).
