LAMOSACCUS. 285 
rugosely punctate, in the @ cylindrical, shining, and rather sparsely punctate. Prothorax broad, 
transversely convex, as wide as the elytra, moderately rounded at the sides, abruptly constricted and 
narrowed in front; the surface coarsely, closely, shallowly punctate, the disc deeply, longitudinally 
depressed in the middle anteriorly and with two large rounded fovex behind this, the short apical portion 
tubulate. Scutellum large, shallowly sulcate. Elytra moderately long, compressed at the sides below 
the shoulders, which are obtuse, the disc here and there depressed; with finely punctured, sharply-cut 
strie, the interstices alutaceous, asperate and angularly raised externally, 3, 5, and 7 here and there 
costate. Pygidium rugosely punctured, in the 9 distinctly, and in the ¢ obsoletely, carinate. First 
ventral segment depressed in the middle in the ¢. Anterior femora with a narrow blunt tooth, the 
intermediate femora with a short tooth, the hind pair obsoletely dentate. 
Length 34-54, breadth 2-24 millim. (¢ 9.) 
Hab. Mexico (Mus. Brit.), Juquila (Sallé); Guatemata, Tocoy (Champion) ; 
Nicaragua, Chontales (Belé). 
Six specimens. ‘The trifoveolate, closely punctured prothorax and the uneven 
elytra sufficiently distinguish this species from its allies. The single example from 
Guatemala has the base of the elytra and the prothorax in part rusty-red. 
6. Lemosaccus atratus, sp.n. (Tab. XIV. fig. 25, front leg, ¢ .) 
Oblong, dull, black, the antenne and tarsi more or less ferruginous; the under surface clothed with white 
pectinate scales. Head opaque, minutely punctate, the eyes moderately large and well separated; rostrum 
short and stout, shining, thickly punctate; antennal club about as long as the funiculus. Prothorax 
almost as broad as the elytra, transversely convex, moderately rounded at the sides, narrowed and 
constricted in front; the surface coarsely, confluently punctate, finely carinate down the middle from the 
base to the apex. Elytra punctate-striate, the interstices alutaceous, and angularly raised and asperate 
externally. Pygidium rugosely punctate. Anterior femora with a rather long, narrow, truncated tooth, 
the intermediate femora with a short, distinct tooth, the hind femora obsoletely dentate. 
Length 23, breadth 14 millim. ( 2.) 
Hab. Panama, Bugaba (Champion). 
One specimen. Very similar to L. sculpturatus, but with the anterior femoral tooth 
longer and truncated at the apex (as in L. ruficornis), and the prothorax less coarsely 
punctate, the median carina more distinct and extending forwards to the anterior 
margin. Mr. Wickham has recently sent me a closely allied form from the Texan 
frontier *. 
7. Leemosaccus erythronotus, sp. n. (Tab. XIV. figg. 26, 26 a, 5,9.) 
Robust, rather broad, dull, black, the prothorax and elytra ferruginous, the antenne fusco-ferruginous, the 
tarsi piceous ; the under surface, the base of the pygidium, and the legs clothed with white, pectinate 
scales. Head opaque, minutely punctate, feebly foveate between the eyes, which are very large and 
somewhat narrowly separated; rostrum short, cylindrical, shining, rather sparsely punctate; antennal 
* Lemosaccus texanus, sp. n. 
Larger and a little more shining than Z. atratus, the rostrum (d ) interruptedly tricarinate, the antenne 
plack, the eyes larger, the prothorax more coarsely punctate and sharply carinate from the base to the 
apex, the scutellum larger and subquadrate, the elytra with the third and fifth interstices rather more 
acutely raised than the others, the anterior femoral tooth broader and obliquely truncated at the apex.— 
Length 3,,, breadth 13 millim. (d.)
