LEMOSACCUS. 283 
broad as or broader than the elytra, strongly rounded at the sides, abruptly narrowed and constricted in 
front, the surface coarsely, very closely, shallowly punctate. Scutellum large, depressed in the middle, 
coarsely punctured in front. Elytra comparatively short, subparallel to beyond the middle, slightly 
compressed at the sides below the shoulder, the latter rounded, the base strongly lobed on each side of the 
scutellum ; with finely punctured, sharply-cut strie, the interstices alutaceous, asperate and angularly 
raised externally, the third prominent at the base. Pygidium dull, alutaceous, and closely punctate; in 
the © sharply (fig. 20), in the ¢ (fig. 19c) more feebly, carinate. Anterior femora with an obliquely 
truncated tooth, the others feebly dentate. Anterior tibie short and broad in the 9, in the ¢ a little 
longer and narrower, in both sexes arcuately dilated on the inner side beyond the middle, but more 
broadly so in the ¢ than in the ?. 
Length 33-53 *, breadth 12-3 millim. (¢ @.) 
Hab. Mextco (Mus. Brit.; Sallé, ex coll. Sturm), Cordova (Sallé); Honpuras 
(Sallé); Guaremana, San Gerénimo (Champion). 
Found in abundance at San Gerdénimo, the specimens varying greatly in size and 
colour. The dilated prothorax, with strongly rounded sides and uniform sculpture, 
the sharply carinate pygidium in the female (the carina appearing angular when viewed 
from the side), the dilated anterior tibie, &c., separate LZ. ruficornis at once from its 
allies. ‘Two of the Mexican specimens are almost black above. | 
2. Lemosaccus radiatus, sp.n. (Tab. XIV. fige. 21, 21a, 4, 2.) 
oD A 
Robust, moderately shining, black, the antenne and tarsi ferruginous; the depressed portions of the 
upper surface clothed with scattered, ochreous, small, piliform scales, the under surface with pectinate 
yellowish scales. Head alutaceous and minutely punctate, feebly foveate between the eyes and 
transversely grooved behind them; the eyes large, deeply emarginate in front, and narrowly separated 
above; rostrum short, cylindrical, shining, finely punctate. Prothorax broad, transversely convex, 
moderately rounded at the sides, abruptly constricted and narrowed in front, sharply, interruptedly 
carinate down the middle; the surface very uneven, depressed on each side of the median carina 
posteriorly, the disc with irregular, sinuous, radiating, raised lines, the base, apex, and flanks coarsely, 
confluently punctate. Scutellum large, cordate. Elytra moderately long, obliquely or transversely 
depressed below the base, near the suture at one-third from the apex, and at the sides about the middle ; 
with finely punctured, narrow, deeply impressed strive, the interstices alutaceous, angularly raised and 
asperate externally, the third costate from a little below the base to the subapical depression. Pygidium 
rugulosely punctate and feebly carinate. Anterior femora with a truncated tooth, the intermediate pair 
obsoletely dentate. 
Length 43-63, breadth 23-3 millim. ( 9.) 
Hab. Mexico, Cordova (Sailé). 
Two specimens. The emarginate eyes, the irregular radiating raised lines on the 
disc of the prothorax, and the very uneven elytra readily separate this species from its 
allies. 
3. Leemosaccus exsculptus, sp.n. (Tab. XIV. figg. 22, 22a, 6, 2.) 
Oblong, robust, slightly shining, black, the tarsi and antenne more or less piceous; the elytra with numerous 
minute yellowish scales behind the scutellum, the under surface with whitish pectinate scales. Head 
dull, minutely punctate, shallowly longitudinally depressed between the eyes above, the latter somewhat 
widely separated; rostrum slightly curved, cylindrical, about as long as the posterior portion of the 
* From the front of the prothorax to the tip of the pygidium.
