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 tibia? 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 Liche)iopha[/us Avould occupy an in- 

 termediate place by the groove surrounding the ej-es and by the entirely 

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

 species only appears to be congeneric with any previously described.

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

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

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

 front, moderately arcuate, gradually' shallower posteriori}- and attaining the 

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

 arcuate and barely attaining the margin of the thorax ; funicle 7-jointed, 

 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- 

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

 connate. 



The above genus contains only Peritelus sellntus Boh. The straight 

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

 ferred, and gives it considerable afl3nity with Cater ectus.

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

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

 with whitish sets sparsely placed. Thorax cylindrical, slightly narrower 

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

 disc moderately convex, coarsely and deeplj' punctured, surface densely 

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

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

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

 erect seta; 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 tibioe are very feebly mucronate and the hind til)ia3 of the 

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