mucro and at all events entirely independently of it, is noticed here. In 

 one genus their occurrence appears to be sexual, in others it cannot be so 

 referred. 



The occurrence of scaly tips to the hind tibiae does not appear, from de- 

 scriptions, in any foreign genus of the group. Those in our fauna might 

 form a distinct group from the Periteli, and would have been so consti- 

 tuted, but I find on examination that LichenopTiagus would occupy an in- 

 termediate place by the groove surrounding the eyes and by the entirely 

 glabrous tips of the hind tibia?. It is also to be regretted that one of our 

 species only appears to be congeneric Avith any previously described.

Rostrum scarcely as long as the head, and separated by an arcuate im- 

 pression, robust, sub-quadrangular, tip emarginate with a smooth space 

 limited by an angular line, alte moderately divergent. Scrobes deep in 

 front, moderately arcuate, gradually shallower posteriorly and attaining the 

 eye. Antenme moderate, sub-terminal, scaly; scape, feebly clavate, slightly 

 arcuate and barely attaining tlie margin of the thorax ; funicle 7-joiuted,. 

 first two joints longer equal, joints 3-7 gradually shorter, club oval. Eyes, 

 round, coarsely granulated and not prominent. Thorax cylindrical, slightly 

 narrower in front, sides feebly arcuate. Scutellum wanting. Elytra oval^ 

 convex. Metasternal side pieces indistinct, narrow. Intercoxal process of 

 abdomen broad, truncate, second abdominal segment not as long as the two. 

 foUoAving united and separated from the first by a straight suture. Claws 

 connate. 



The above genus contains only Peritelus sellatus Boh. Tlie straight 

 first alxlomiual suture excludes it from the genus to which it has been re- 

 ferred, and gives it considerable affinity witli Caterectus.

Form oval, moderately robust. Head and rostrum as long as the thorax, 

 rostrum with fine median line, surface densely scaly, scales dark cinereous, 

 with whitish setse sparsely placed. Thorax cylindrical, slightly narrower 

 in front, broader than long, sides feebly arcuate, apex and base truncate, 

 disc moderately convex, coarsely and deeply punctured, surface densely 

 scaly and with erect whitish setpe, scales brownish in a broad median band, 

 pale cinereous at the sides. Elytra oval, slightly inflated, nearly three 

 times as long as the thorax, striate, strife punctured,, intervals flat with 

 erect set* irregularly placed, surface densely covered with cinereous scales 

 with large discal pale-brownish space limited behind by a sinuous darker 

 line. Body beneath less densely scaly. Length .18 inch ; 4.5 mm. 



When deprived of scales the surface color is pale brownish. The an- 

 terior and middle tibiae are very feebly mucronate and the hind tibia; of the 

 9 have two short fixed spurs. The color of the scales varies and the large-
