Head 3 mm. broad, Eacli mandibh^ with a large acute basal 

 tooth on tlie hrst ventral rib. Seta A'A not more than tiie width of 

 the ocellus removed from ocellus II. Line connecting the insertions 

 of setae A3 and ()2 passing through ocellus 1. Setigerous tubercles 

 of abdomen occasionally with a few spinules. 



Body about 25 mm. long and 3.5 mm. broad; skin set closely A\ith

Head setae and pun(;tures as follows: A2 approximately equidistant 

 from A I and A3 ; A2 at least twice as near to A 1 as to Pa ; Aa equidistant 

 from A2 and A3; Aa three times as near to A2 as to Pa; A3 not more 

 than the width of the ocellus from ocellus II ; Pi much above the level 

 of the apex of the front and decidedly nearer to Adf2 than to Adf 1 ; 

 Pa, Aa and A3 not in a straight line; interspace A2-~Aa about half 

 Pl-Pa; Pb about twice as near to P2 as to Pi : Adf a somewhat nearer 

 to Adf2 than to Adf 1 ; ocellus VI ecjuidistant from 01 and 03 or nearer 

 to 03; 02 ecjuidistant from .\3 and Ol or nearer to A3; 02 dis- 

 tinctly nearer to A3 than to Ll ; Ll three times as near to La as to 

 02; SOa approximately equidistant from S02 and S03; S03 approxi- 

 mately equidistant from Gl and 03
