 on its prey. The species wMch is now before us inhabits sandy 

 spots, and is of a dark yellowish-brown, so exactly resembling 

 the colour of sandy gronnd, that the insect cannot be detected 

 without some difficulty, in spite of its rather large size. It is a 

 native of Egypt, and some specimens in the British Museum 

 were brought thence by Sir J. G. Wilkinson. The generic name 

 £remwphila is formed from two Greek, words signifying * desert- 

 lover," and is given to the insects in allusion to their habits. 



It is an odd-looking creature, the fere-legs being thick and 

 sturdy, while the two remaining pairs are long and very slender. 

 They are of a paler colour than the rest of the body. Both the 

 elytra and wings are thick, short, and rounded, from which the 

 insect derives its specific name of rvtuwlipmnig, or "round- 

 winged." m the wings themselves, which in tins group of 

 insects are generally translucent, are in this species dark and 

 opaque like the elytra. If, however, tbe elytra are opened and 

 the insect examined from beneath, a brigbHy-coloured mofallif
