ToTHiLL (J. D.). Note regarding Types of some Tachinidae (Diptera) 



from India.~BHll. Ent. Res., London, xiii, pt. 2, August 1922 

 p. 181. 



This paper describes the disposition of the type material of the 

 species dealt with in a previous one [R.A.E., A, vi/331]. 



The following notes on s3aionymy of the species in question are 

 contributed by Major E. E. Austen: Scnnllia transversa, Toth. = S. 

 sobria, Wlk. ; 5. ursinoidea, Toth. = S. fulva, Wlk. ; Gonia himalensis, 

 Toth. = G. capitata, DeG. ; Paraphania fuscipennis, Toth. =-. Orectocera 

 beelzebuh, Wied., of which Tachina imbrasus, Wlk., is also a synonym;. 

 Frontina kashmiri, Toth., should be referred to the genus Podomyia';. 

 and Lophosia excisa, Toth., is probably a Phania.

Descriptions are given of the Trichogrammatid, Chaetostricha 

 cratitia, sp. n., from two females bred from eggs of the Hispid beetle, 

 Prontecotheca reichei, Baly, injurious to the foliage of the coconut. Coco's 

 nucifera, in Fiji, and of Encyrtus cotterelli, sp. n., from three males bred 

 from a third instar nymph of the Capsid bug, Sahlbergella theobromae, 

 Dist., injurious to cacao [Theobroma cacao) in the Gold Coast. This 

 species is only provisionally assigned to the genus Encyrtus.

Partn. — Bull. Ent. Res., London, xiii, pt. 2, August 1922 pp 189- 

 195, 1 plate, 10 figs. 



This paper continues the study of the immature stages of Bibionids 

 [R.A.E., A, X, 41] and deals with Dilophusfebrilis, L., and D. albipennis, 

 Mg. These are the commonest species of the genus in Britain, and both 

 frequently occur in great numbers. D. febrilis has often been recorded 

 as damaging the roots of plants, especially hops, in the larval stage. 

 There are apparently two generations a year, adults appearing in May, 

 and again in smaller numbers in August' and September. The eggs are 

 laid in a mass in a cell in the soil. D. albipennis seems to have only one 

 generation, which appears in May, oviposition being similar to that of 

 D. febrilis. The four larval stages and the pupa of each species are 

 described, and the differences between the larvae and pupae of Bibio 

 and Dilophus are pointed out.

 pods from Soil.—Bidl. Ent. Res., London, xiii, pt. 2, August 1922, 

 pp. 197-200, 2 figs. 



The apparatus here described consists of an outer case of galvanised 

 iron, supporting three sieves of different mesh, that with the largest 

 mesh being on the top, the intermediate size in the middle and the 

 smallest below. A lead pipe fitted with a large rose with a convex face 

 is clamped to the upper edge of the case and is connected at the other 

 end with a water supply, for which there is an outlet at the bottom of the 

 case. The soil to be examined is placed in the upper sieve, the water 

 turned on and the soil thus washed into three lots in the sieves, the 

 finest particles being carried away with the waste water and the insects 

 being retained in the various sieves according to their size.
