336 Mr. M. Cameron on new StaphyliinJre 



Shape of head as in preceding, foveolate on either side 

 between the eyes, rugulosely sculptured, except posteriorly. 

 Antennas testaceous, of similar structure to the preceding. 

 Thorax a little narrower than the head and elytra, longer 

 than broad, flask-shaped, impressed on either side behind the 

 widest part ; disc with fine smooth carina, the rest of the 

 surface with rugulose umbilicate sculpture. Elytra as long 

 as, or a little longer than, the thorax, as long as broad, 

 moderately coarsely and closely punctured. Abdomen finely 

 and sparingly punctured and pubescent. 



$ . First joint of posterior tarsi thickened, sixth ventral 

 plate with a shallow emargination. 



Grenada, St. Vincent (H. H. Smith). Type in the 

 British Museum. 



21. Echiaster waterhousei, sp. n. 

 (fauvel, in litt.) 



Ferruginous, dull ; elytra testaceous with apical half 

 black. 



Length 23 mm. 



In coloration nearest to E. filum, Slip., and E. curtus, 

 Slip. : from the first very distinct by the much shorter and 

 broader thorax, and less elongated and attenuated build; from 

 the last by the much narrower and less robust build, smaller 

 head, narrower thorax, with the longitudinal impressions 

 and median elevated line much less distinct, and the liner 

 sculpture. 



Head subquadrate, longer than broad, dull, ferruginous, 

 posterior angles rounded ; eyes rather large, their diameter 

 less than the length of the temples ; puncturation close, 

 rugose, umbilicate. Antennas testaceous, short ; first joint 

 much dilated ; second transversely oval ; third globose, much 

 smaller than second ; fourth to tenth transverse, gradually 

 increasing in breadth, the penultimate about three times as 

 broad as long ; eleventh not quite so long as the two preceding- 

 together. Thorax narrower than the head and the elytra, 

 longer than broad, oval-oblong, widest at the anterior angles, 

 which are rounded, narrowed in front and behind, with the 

 posterior angles obtuse ; disc posteriorly with a longitudinal 

 impression on either side of the middle line, which by con- 

 trast appears more or less elevated ; sculpture as on head. 

 Legs testaceous. Elytra longer than the thorax, longer than 

 broad, the basal half testaceous, the apical half black, usually 

 sharply defined, but sometimes only represented by a fuscous 

 cloud. Sculpture close, rugose, with short pubescence.
