SpiRosTREPTUS (Nodopyge) exocceti, sp. n. 



Species belonging to the immucronate homomorphous group. 



Number of somites 54 or 55. Total length about 22 millim. 



Head-plate convex from above downwards and from side to side, 

 marked above with a short median sulcus ; eyes small, consisting of 

 about sixteen or seventeen ocelli ; front sparsely punctured and 

 hirsute ; labial margin slightly concave and furnished with five 

 small teeth. 



Somites. Anterior and posterior margins of the first tergite 

 converging gradually and meeting at an angle of about 50^ ; apex 

 of angle rounded, with raised margin ; antero-lateral margin as far 

 as the region of the eyes raised ; running from the anterior margin 

 of the tergite, from a point on a level with the ocular area back- 

 wards and downwards to the posterior margin, is a single sulcus, 

 above the posterior extremity of which there may be a few short 

 sulci. Infero-lateral portions of the hinder half of each somite 

 longitudinally striated, the strise being somewhat widely separated ; 

 foramina repugnatoria small, round, situated in the middle of the 

 plate above the striated portion ; upper surface of somites bearing a
