406 Mr. G. A. K. Marsliall on new 



boss-like tubercle at the base of the iiftli interval. Apart 

 from their smaller size, these species differ in the presence of 

 a smooth longitudinal space on either side of the thoracic 

 furrow and in the absence of the large conical tubercle on the 

 second interval. 



Uipjiorrlimus occidentalis, sp. n. 



Long. 15, lat. 7 millim. 



Head convex, obscurely punctured and covered with large 

 brown scales, except a short smooth line on forehead, which 

 contains a small jtuncture ; a narrow ring of white scales 

 round each eye ; anteocular furrows practically obsolete. 

 Bostrnm not incised at base, as long as head and prothorax, 

 very little curved. Upper surface rather convex at base, but 

 broadly excavate towards apex, punctured and covered witli 

 bi own scales except for a broad smooth central line ; lateral 

 sulci not meeting at base and filled with large white scales ; 

 upper pair very broad and deep, the lower narrow and faint ; 

 scrobes directed beneath base of rostrum ; inferior basal trans- 

 verse furrow obsolete. Antennce with dense pale scaling and 

 black seta3 ; scape not nearly reaching eye ; the two basal 

 joints of funicle subequal. Prothorax as long as broad, apex 

 narrower than base, sides slightly dilated, with a small tuber- 

 cular angulation before middle; ocular lobes strongly deve- 

 loped. Upper surface convex, with a broad lance-shaped 

 central furrow containing a low carina and flanked on either 

 side by two rows of closely but irregularly placed tubercles ; 

 beyond these is a smooth longitudinal band, followed by a 

 single regular row of tubercles close to the lateral margin, 

 and below this another similar row, of which a single 

 tubercle is rather larger than the others and forms the lateral 

 projection ; scaling on disk brown, but greyish in central 

 furrow and on prosternum. Elytra oblongo-ovate, shoulders 

 roundedly ijrominent, sides very little rounded, broadest 

 about middle, apical processes of elytra long and sharp. 

 Upper surface convex, with regular rows of large and deep 

 punctures, the alternate intervals dissimilar ; intervals 1, 2, 

 4, and G devoid of tubercles (except a single small one near 

 base of the latter) ; intervals 3 and 7 with complete rows of 

 conical tubercles, which become more distant, larger, and 

 siiarper towards apex ; interval 5 with a very large, rounded, 

 boss-like tubercle at base, followed by six closely-set conical 

 tubercles, and a solitary larger and sharper one about the 

 summit of the declivity ; scaling dense, dark brown, except 

 the suture and reflexed margins, which are grey ; the boss-
