defined b3'aii arcuate impunctate line. Elytra with sides lightly 

 but decidedly narrowed to humeral angles, these marked (not 

 dentate); 1st stria lightly marked, entire; 2nd and 3rd hardly 

 perceptible; interstices flat, 3rd bipunctate along course of 3rd 

 stria, anterior puncture about basal third, posterior at beginning 

 of apical declivity just above the short apical recurved striole. 

 Length 1-8-2-1, breadth 0-85-0-95mm.

This small species is characterised by the sides of the prothorax 

 strongly sinuate towards base, which differentiates it from T. 

 nniformis, Blkb., T. similis, Blkb., and 2\ infuscatvs, Blkb. In 

 the shape of the prothorax it resembles T. transversicoUis, ^lacL, 

 but differs by smaller size, elytra with the discoidal setigerous 

 puncture nearer the suture, recurved striole of apex much shorter 

 and more feebly impressed, sides more strongly rounded to 

 shoulders, humeral angles well marked, not rounded, itc. 



It would come into Section "«" in the table of species I have 

 given in these Proceedings (1896, p. 3.59), and may be tabulated 

 thus: —

I have now to describe two small Subulipalpi in my collection, 

 both of which I refer provisionally to the genus Tachys, though 

 neither seems in its place in that genus. These two species {T. 

 ohliquiceps and T. setiger) show no close affinity to one another; 

 in fact I believe each to represent a distinct genus, but I know 

 too little of the recent classification of the Subulipalpi to place 

 them in their proper position in the tribe, or to feel justified in 

 suggesting new genera for them. Both have the eyes distant 

 from the buccal fissure beneath (a trechideous character), but 

 both seem true Subulipalpi leading towards the Terihptides.
