affiiiitij of the genus Pohjctcnes, GifjUuli, ^^c. 311 



continued nearly to the apex of the metasternnin ; on each 

 side there is a deep longitudinal cavity, into which the 

 anterior legs can be withdrawn. The mesosternnm can 

 be traced by viewing the insect laterally, but it is not 

 visible below. The metasternum is flat, with some stiff 

 hairs on the posterior margin, and two longer ones at 

 each lateral angle. The abdomen has rather closer and 

 darker hairs below than the rest of the body ; at the base 

 there is a somewhat raised triangular portion, which seems 

 to represent the basal segment. 

 Length 3 mm. 



The specimen from which the foregoing description is 

 taken was mounted on the same card as a specimen of 

 Strehla vespertilionis from Colombia. 



Pohjc.ienes lyra. 



Most nearly allied to P. molussiis, G. & AV., but much 

 more elongate and narrower, uniform pale pitchy-yellow. 

 The anterior portion of the head smooth and shining, Avith 

 three or four stiff bristles on the margin near the posterior 

 angles. The antennna apparently with two small joints at 

 the base, the 3rd joint very long, compressed, concave, 

 or channelled on the inner side, the 4tli joint about two- 

 thirds the length of the 3rd and more slender, the 5th 

 joint elongate fusiform. The anterior portion of the head 

 below, with five or six cultriform spines placed obliquely 

 near the posterior angles. The posterior portion of the 

 head above smooth and shining, with a ridge on each side 

 of the disk ; the ridge which margins the sides anteriorly 

 turi.s away posteriorly from the hind angles, and is set 

 with stiff bristles which increase in length as they aj)proach 

 the hind angles ; the basal margin is closely set with short 

 cultriform spines. This portion of the head is concave 

 below, Avitli the anterior margin set with cultriform 

 spines, the sides with stiff bristles which become longer 

 posteriprly ; at the posterior angle there is a conical 

 process Avhich terminates in a very long stiff bristle. 

 The prothorax above has short stiff hairs scattered 

 over the surface, the basal margin has a row of cultriform 

 spines which are pitchy in colour. The dorsal plates of 

 the mesothorax are studded with minute hair-bearing 

 tubercles. The abdomen is sculptured in the same 

 manner. The prothorax is concave below on each side, 

 so that the anterior legs are entirely hidden in the cavity
