various insects penetrate into the soil, and the bearing of such 

 organisms in relation to agriculture. 



Coleoptera. — T. H. Beare and H. Donisthorpe {Ent. Month. 

 Mag., 1922, 183) record Aulonium ruficorne 01. and Hypophlceus 

 fraxini Kugel from logs of Scots pine in the Forest of Dean, 

 both species being hitherto unknown in the fauna of the 

 British Isles. E. N, Pavlovsky {Quart. Journ. Mic. Set., 66, 

 627-55) has a detailed memoir on the structure and biology 

 of the larva of the water beetle Hydrophilus caraboides. P. H. 

 Timberlake {Proc. Hawaiian Ent. Soc, 1922, 121-33) has 

 investigated the inheritance of colour variations of the lady- 

 bird Ccslophora inequalis, and finds that the black form is 

 recessive to the dominant normal and nine-spotted varieties. 

 S. A. Graham {Ant. Ent. Soc. Am., 15, 191-200) has studied 

 the venation of the hind-wings in a number of Coleoptera, 

 and finds that the hypothetical venational type for that order 

 does not differ greatly from that hypothetical type of Comstock 

 and Needham for insects in general. In the case of Coleoptera 

 it is characterised by the apical fusion of R3 with R4, and of 

 R5 with Ml. The Colorado potato beetle has recently appeared 

 in the Gironde {Bull. Soc. Agric. Fr., 54, 250-2) over an area 

 of about 100 square miles. A sum of approximately £20,000 

 has been voted for its control. A. M. Altson {Ann. App. 

 Biol., 9, 187-95) describes the young larva of Lyctus brunneus. 

 It appears that, at maturation, the first instar larva commences 

 to feed upon the residual yolk contained in the anterior part 

 of the egg, remaining within the chorion to do so. It takes 

 three to five days to accomplish this, and does not commence 

 to bore into wood until its second instar. A. W. Rymer 

 Roberts {ibid., 306-24) has a third instalment of his paper 

 on the life-history of " wireworms " and provides a table of 

 the larvse of British Elateridae based upon that of Henriksen. 

 The metamorphoses of some Argentine Cassidinae are described 

 and well figured by A. G. Frers {Physis, 6, 245-62). J. C. F. 

 Fryer {Journ. Ministry Agric, 29, 748-49) gives an account 

 of a new apple pest, Anthonomus cinctus, which has recently 

 been found in Great Britain. It is suggested that it be known 

 as the bud weevil from the fact that it attacks the buds of 

 apple and, more especially, pear. The insect is prevalent in 

 some parts of the Continent, but so far appears to be very 

 local in Britain, and may be an indigenous species which has 

 hitherto been overlooked. 



Lepidoptera. — H. D. Peile {Journ. Bombay Nat. Hist. Soc, 

 28, 50-70) discusses the butterfly fauna of Mesopotamia, 

 contributing notes on forty-four species. This fauna, like the 

 flora, is more English in character than, for example, the 

 fauna of southern France. In their work on The Genitalia of
