62 MR. G. A. K. MARSHALL ON COLEOPTERA [Jan. 19, 



high narrow ridge composed of agglomerated tubercles ; beyond 

 this a broad smooth space, followed by a lateral ridge quite similar 

 to the dorsal one ; beneath this are two or three scattered 

 tubercles, including a large compressed one which forms the 

 angular projection ; all the tubercles smooth and without seta? ; 

 scaling dense and brown, but paler in the median fuiTOW, the 

 prosternum greyish. Elytra ovate, shoulders sloping, sides mode- 

 rately rounded, broadest about middle, apical processes short but 

 sharp. Upper surface convex, with regular rows of lai-ge shallow 

 punctures; intervals 1, 2, 4, and 6 entirely devoid of granules or 

 tubercles ; intervals 3 and 7 Avith complete rows of small rounded 

 shiny tubercles, becoming rather larger and more conical towards 

 apex ; interval 5 with a similar row but ceasing abruptly behind 

 middle ; intei'vals 1 and 2 very narrow, so that the space between 

 intervals 3 and 5 is about as broad as that lying between the 

 third intervals of the two elytra ; scaling dense, uniform earthy 

 brown, the margins broadly greyish white. Legs with dense pale 

 scaling ; posterior tarsi with joints of about the same width, 1st 

 longer than 2nd and 2nd than 3rd.

H. canalicidatus Mshl. 1. c. p. 408 (1902). 



Long. 22, lat. 10 mm. 



Head convex, closely but indistinctly punctin-ed and covered 

 with dense brown scaling, forehead with an elongate central 

 fovea ; anteocvxlar furrows deep and distinct in their upper half, 

 obsolete below, Rostrutn not incised at base, as long as head and 

 prothorax, curved beyond middle. Upper surface with the edges 

 angular and subj)arallel throughout (the gense, however, dilated at 

 apex), plane at base, shallowly excavate towards apex, with fine 

 close punctuation and sparse scaling throughout, except along a 

 narrow smooth central line ; upper lateral sulci shallow, not 

 meeting at base and vanishing beyond middle, the lower pair deep 

 and distinct ; scrobes directed beneath base of rostrum ; inferior 

 basal furrow shallow. Antenna', with scape not reaching eye ; 

 the two basal joints of funicle subequal. Prothorax as long as its 

 width at base, apex narrower, sides angulated and with a small 

 but prominent lateral tubercle about middle, ocular lobes well 

 developed. Upper surface not veiy convex, with a broad deep 

 central fvirrow, containing a strong carina, and flanked on either 

 side by a high ridge of agglomerated tubercles ; beyond this is a 

 broad smooth space, followed by a sharply defined band of small 

 irregularly placed tubercles along the extreme edge ; scaling 

 dense, brown above and turning suddenly to white on the pro- 

 sternum immediately below the lateral tubercles. Elytra ovate, 

 shoulders sloping, sides moderately i"ounded, broadest about 

 middle, apical processes short but sharp. Upper surface convex, 

 with regular rows of small shiny granules in lieu of punctures :
