ACANTHOLOPHUS. 



A . Franklinensis, sp. nov. Oblongus ; niger ; albosquamosus, 



squamis niveis condensatis lineam longitudinalem a rostro ad 



elytrorum apicem recurrentem efficientibus ; rostro utrinque 



supra antennarum basin spina longa valida, supra oculum 



spina trifida perlonga instructo ; oculis angustis ; antennarum 



funiculi articulo 2° 1° sat longiori ; prothorace spinis acutis 



4-seriatim instructis ; elytris apice late divaricatis minute 



mucronatis 7-seriatim tuberculatis vel spinosis [serie 1* 



suturali tuberculis parvis obtusis, 2*" tuberculis obtusis paullo 



majoribus (2 vel 3 posticis conicis acutis), 3" tuberculis 



obtusis etiam majoribus (2 posticis permagnis conicis acutis), 



4'' 1* simili sed fere obsoleta, 5'' T* simili, 6" tuberculis sat 



magiiis (anticis obtusis, posticis acutis subspiniformibus), 



7''' postice abbreviata tuberculis subspiniformibus, instructis] ; 



pedibus albo-squamosis nigro-setosis. 



An extremely distinct species remarkable for the well marked 



snowy scales with which it is clothed. These cover the rostrum 



from the base of the antenna hindward, then continue as a line 



along the middle of the head, then fill the interval between the 



dorsal series on the prothorax (in the middle of which nevertheless 



is a narrow scaleless black line), and then as a narrow line occupy 



the scutellum and the suture quite to the apex of the elytra ; they 



are also more interruptedly (but still very conspicuously) dispersed 



over the sides of the prothorax and elytra, form a vitta between 



the sixth and seventh series of tubercles on the latter, and are 



thinly sprinkled over the undersurface and the legs. The parts 



not covered with snowy white scales appear to the naked eye 



quite black, but are seen under a lens to be thinly sprinkled with 



brown scales. The head and prothorax bear (no tubercles, but) 



only large sharp spines ; that over the eye is like the antler of a 



deer, consisting of two long spines (the front one curved forward 



and upward, the hinder curved upward and hindward. and sending 



ofi' a short branch anteriorly at about half its length) springing 



from a common stalk, of which the hinder is the longer, and is 



scarcely shorter than the distance from its base to the apex of 



the rostrum ; on the prothorax the dorsal series each contains five 



long sharp spines gradually decreasing hindward, of which the 



front one is the longest, and is bifid, while each lateral series 



consists of a spine near the base about as long as the longest of
