 pahs King, IS i-atlier closely allied to this species, but has

This genus in many respects closely approaches Bry- 

 axis, but is distinguished therefrom by the elongate max- 

 illary palpi, and the two (minute) claws of the tarsi. It 

 also approaches nearly to Gerallus, but has the maxillary 

 palpi less elongate, the antennae more distant at their inser- 

 tion, the head less rostrate, and the eyes placed at the 

 hinder angles instead of at the sides ; the hind body more 

 elongate. T?/rus formosus, King, is however in some of 

 these points intermediate between the two genera. 



Durhos priscus, n. sp. Castaneo-testaceus, sat nitidus, 

 fere impunctatus; capite obsolete bifoveolato; thorace 

 parvo, medio ante basin foveola minutissima ; elytris stria 

 suturali, striaque discoidali ante apicem desinente. Long, 

 corp. 1| mm. 



Antenna slender, much longer than head and thorax, 

 the basal joint rather long, slightly thicker than the fol- 

 lowing ones, joints 9 — 1 1 forming a long slender club. 

 Head small, but with large prominent eyes, its upper sur- 

 face flat, with the frontal tubercles very faintly marked, 

 and with tAvo minute fovea3 between the eyes. Maxillary 

 palpi pale yellow, nearly half as long as the antenna?. 

 Thorax small, not much more than half as broad as the 

 elytra, not so long as broad, narrowed towards the base, 

 with the front angles rounded. Elytra longer than the 

 thorax, moderately narrowed at the shoulders, each with a 

 fine sutural stria, and also with a very fine discoidal stria 

 which does not extend to the extremity. Hmd body with 

 the first dorsal segment shining and impunctatc, ou each
