Obs. Professor Burmeister considers that Bacteria JEgyp-

 scarcely agree with such an opinion, my reasons for which 

 will be stated under the next species.

Hab. In iEgypto. B.M. 



The typical specimen of this insect in the British Mu- 

 seum collection is a male, very slender and cylindrical, with 

 the following proportions : — 



Head, lin. 1^ ; proth. lin. 1 ; mesoth. lin. 6 ; metath. 

 lin. 5 ; abdom. lin. 12. 



The antenna; are very slender, filiform, 18- or 19-jointcd, 

 as long as the mesothorax. The head is marked on each 

 side with a dark stripe. The thorax and abdomen are 

 marked on each side with a slender dark longitudinal line, 

 with a lateral paler one. The fore and middle legs are 

 very long and quite unarmed (the hind ones are wanting). 

 The basal joint of the tarsi is remarkably elongated, as are 

 also the ungues and pulvilli. The three terminal segments 

 of the body are very convex (when seen ' laterally), of 

 nearly equal size, the last furnished with a narrow terminal 

 lobe, and with two long, exserted, clavate, curved, anal 

 styles. The three terminal ventral segments are but little
