100 Descriptive Gatalogtie [1897. 



testaceous, tarsi red ; head slightly attenuate in front, sulcate longi- 

 tudinally, and having two obsolete foveas set in the middle between 

 the eyes, vertex slightly convex, cheeks glanduloso-squamose behind ; 

 antennae thick, first joint large, slightly obconical, second a little 

 narrower, quadrato-transverse, third to eighth smaller than the others, 

 equal to each other and transverse, ninth a little larger, transverse, 

 eleventh large, much truncate at base, obtuse at apex ; prothorax 

 ovate, convex, a little broader than the head, sinuate at base, truncate, 

 two lateral foveas and a median minute one ; elytra triangular, not 

 broader at base than the prothorax, oblique laterally, more than three 

 times broader at apex, apical margin with very pale glandulose 

 squammae ; abdomen longer than the elytra, slightly rounded laterally 

 and a little broader, very broadly marginate, rounded at apex, first 

 dorsal segment larger than the others, and with the median apical 

 part having an acute, straight tubercle ; metasternum convex, first 

 ventral segment covered with a whitish glandulose pubescence, 

 second one large ; abdomen slightly concave underneath ; legs 

 slightly compressed. Male. 



This very fine insect, owing to the squamose pubescence and 

 short and triangular elytra, is not unlike Psclapkus npacus, Schauf., 

 from the Amazon.

Teibe CTENISTINI. 



Head provided with an antennal tubercle, cheeks more or less 

 dilated in front in a tubercle ; maxillary palpi conspicuous, most 

 often penicillate ; first ventral segment of abdomen hidden by the 

 posterior coxae ; claws double and equal in size ; the pubescence is 

 always squamose. 



This tribe differs from the PselapUini by the mucronate sides of 

 the head in the anterior part, the first ventral segment of the 

 abdomen is short, and more or less covered by the hind coxae, the 

 two claws of the tarsi are equal, and the pubescence is always 

 squamose. 



This tribe is found everywhere. The insects belonging to it are 

 generally met with in damp or swampy places, and may be caught 

 flying at sunset ; some are found under stones, others in ants' nests.
