and rather deep, except near the anterior margin where they are 

 very fine; elytra slightly wider at the base than the thorax, without 

 basai dépression, strongly punctate-striate, less strongly marked 

 near the apex, the interstices costate at the sides only, below dairk 

 blue, the abdomen nearly black, the anterior femora with a very 

 small, the posterior ones with a larger tooth, tibise feebly cha- 

 nelled.

Pheloticus semistriatus Fairm. 



A spécimen in m y collection from Madagascar agrées very well 

 with M. Fairmaire's description but in my insect the breast and legs, 

 with the exception of the fulvous apex of the tibiae are deep black, 

 not fulvous, but as this seems to be the only différence it is probable 

 that the species varies much in coloration. 



COLASPOSOMA SEMIPURPUREA n. sp. 



Dark purplish or violaceous, the antennse and tarsi black, head, 

 thorax and elytra very closely, evenly and moderately strongly 

 punctured, the sides with a narrow longitudinal smooth space from 

 the middle to the apex. 



Length 8-10 mill. 



A large and uniformly sculptured species of which I received two 

 spécimens of great diff'erence in size and of which the larger one 

 seems to represent the maie; the head very closely and strongly 

 punctured with the interstices longitudinally strigose at the sides, 

 antennse entirely black, the lower six joints shining, the rest opaque 

 and distinctly widened; thorax twice as broad as long, the sides 

 evenly but not strongly rounded, the surface evenly and closely 

 punctured throughout, the punctures of the same size than those of 

 the head; elytra similarly sculptured, with the interstices likewise 

 minutely punctate, the latéral margin accompanied from the middle 

 to the apex by a longitudinal smooth costa; below and the legs 

 nearly black with a slight purplish gloss, the femora very robust 

 with a very minute tooth, the tibise widened at the apex, prosternum 

 clothed with rather dense grey pubescence, flancs of the thorax 

 strongly punctured.

Both spécimens are of uniform purplish colour. 



NODOSTONOPA n. gen. (Eumolpid^).
