COLEOPTERA,

serving the convex direction from the angles to the middle, where it is also 
distant from the base ; the elytra have all their interstices flat, the gibbosity 
behind the base is entire and broad; and lastly, the general coloration is 
quite different. 
Head constructed as in the preceding species, with the forehead some¬ 
what broader, entirely fuscous-black. Eyes smaller, approaching together 
less closely in front. Rostrum proportionally narrower and longer, being 
nearly as long as broad, and consequently subquadrate, having the same 
depression, but its central impression is rather longitudinal than transverse, 
whilst that existing at each side of the base above the eyes is much shal¬ 
lower. Antenna more elongate in the male, as has been remarked above. 
Thorax proportionally more conic, or more narrowed at the apex, 
clothed with fuscous pile, scattered with extremely rare thin white 
detached dots ; two basal subquadrate spots, not far from each other and 
not extending beyond the carina, are formed of a blackish velvet-like 
tomentosity : the posterior carina, although distant, is nearer to the base in 
its middle than above the blackish patches; it then inclines progressively 
nearer to the base towards the posterior angles, which it meets, and which 
are evidently truncate at their tip. 
Scutellum proportionally rather smaller, clothed like the thorax. 
Elytra of the same shape and convexity, but proportionally shorter 
and broader, rather less dilated behind the middle, more obtusely rounded 
at the apex, having behind the base, not far from the suture, a subcircular 
entire tubercle ; shoulders less callose; they are more obsoletely punctate- 
striate, and all the interstices are fiat; clothed and irrorated like the 
thorax. 
Pygidium narrower and more elongate, semielliptic, less convex and 
inflexed, evidently punctate-rugulose. 
Body beneath clothed like the upper parts, densely irrorated with 
a thin white pile. 
Legs similarly constructed, clothed and irrorated like the abdomen ; 
a subbasal and an apical ring of the tibiae, and the apex of the two anterior 
joints of the tarsi, clothed with yellowish fulvous pile.
