Zeugma Westwood. 

 This genus has the wings more than half the length of the tegmina, 

 and the cubital and claval areas are normal with normal claval and cubital 

 veins, and so it does not come into the Zoraidinae where I placed it 

 formerly. 



Phenice Westwood. 



Plienice was erected by Westwood for three species — Derhe fritil- 

 laris Boh., Derhe fasciolata Boh., and Derhe stellulata Boh. The 

 generic description was based upon D. fasciolata Boh., and figures of 

 that species were given and specially referred to. In the same work 

 Westwood remarks : — 



" On various pi'svious occasions I have endeavoured to establish a fixed 

 principle relative to the selection of the typical species in genera, established 

 by ouv predecessors, which combined several distinct forms under one generic 

 name. For this purpose, I have considered that the species which could be 

 proved to have been more especially under the examination of the founder of 

 such genera, ought to retain the old generic name ; and where this could not 

 be learned from any particular expression, that we should resort to the firvSt 

 species in the genus." 



This constitutes a type fixation, and so Derhe fasciolata Boh. must 

 be the type of Phenice Westw. The two species belong to different 

 sections of the Derhidae : fritillaris to the Zoraidinae Siwd fasciolata 

 to the Cenchreinae. 



Note on the hahits of Cryptophagus populi Payk. — On July 2oth last, while 

 wandering about the New Forest in company with Mr. F. Muir, we came across 

 a number of burrows oi Dai^ypoda hirtlpes, with the bees busy at work, as shown 

 by the frequent upheaval of the sandy soil in the holes made by tliem. Two 

 females of the bee were taken home, one living, the other dry and imperfect. 

 These were subsequently pinned, placed in a small box, and forgotten. Some 

 days afterwards, on casually opening the box, a living Cryptophagus populi 

 was found beneath the imperfect example of the bee, to which it must have 

 been attached when the latter was secured. It is possible that this beetle 

 preys upon the bees, as a mounted Ja-;sid in the same box had been partlv 

 devoured by it. In any case, the Cryptophagus must live in association with 

 the Dasypoda. I have twice found specimens of an allied insect, Anthero- 

 phagus pal/ens, attached to living Bombi, these beetles being thus can-ied on 

 the hairs of the bees from the flowers visited by them to their nests. In 1875
