AULEUTES. 147 
Metasternum arcuato-emarginate, the excavation very deep, closed behind, and extending as far as the 
posterior margin of the middle coxe. Fifth ventral segment transversely depressed in the middle. 
Pygidium deeply foveate. Legs short and rather stout; femora very shallowly sulcate beneath; inter- 
mediate tibie unguiculate ; tarsal claws angularly dilated at the base. 
Length 21, breadth 18 millim. (¢.) 
Hab. Guatemaua, San Juan in Vera Paz (Champion). 
One worn specimen, a male. It may be known by the very large eyes (larger than 
in any Ceuthorrhynchid known to me), the sinuate sides of the elytra, the deeply 
foveate pygidium, &c. 
2. Auleutes asperipennis, sp. n. 
Short ovate, shining, black, the anterior portion of the prothorax and the elytra reddish or brown, the antenne, 
tibize, and tarsi more or less ferruginous, the femora usually infuscate; the elytra set with numerous 
short, stiff, semierect, pallid setee, and a line of cinereous scales at the base of the suture, the rest of the 
vestiture very sparse and fine. Head and rostrum rugosely punctate, the latter exceedingly stout, arcuate, 
and not longer than the prothorax. Prothorax constricted and much narrowed in front; coarsely 
punctate, the disc without prominences, the lateral tubercles conspicuous. Elytra subcordate, depressed 
along the suture anteriorly ; deeply punctate-striate, the interstices rather convex and set with setigerous 
granules. Metasternum arcuato-emarginate, the excavation very deep, closed behind, reaching as far as 
the posterior margin of the middle coxe. Fifth ventral segment feebly foveate, and the tibie unguiculate 
at the inner apical angle, in the ¢. 
Length 14-132, breadth 1-145 millim. (¢ Q.) 
Hab. Panama, Bugaba (Champion). 
Eleven specimens. The only Central-American Ceuthorrhynchid known to me with 
minute, pointed, setigerous granules on the elytra. A. asper and A. tenuipes (Lec.) 
appear to be allied forms. 
3. Auleutes sulcifrons, sp. n. 
Short ovate, shining, black, the antenne, apical margin of the elytra, knees, tibie, and tarsi ferruginous ; 
clothed with widely scattered, minute, hair-like, white scales, which on the elytra are almost wholly 
condensed into two common, interrupted fascia—one, before the middle, strongly undulate, the other 
towards the apex, transverse. Head coarsely punctate, sulcate between the eyes ; rostrum stout, curved, 
not longer than the prothorax, very sparsely punctate, smooth along the middle. Prothorax constricted 
and much narrowed in front, coarsely punctate; the disc shallowly sulcate and with two short oblique 
ridges, the lateral tubercles acute and very prominent, the anterior margin feebly emarginate in the middle 
and with two small widely-separated prominences. Elytra rounded-triangular, sinuate at the base, the 
humeri rather prominent; deeply punctate-striate, the interstices somewhat asperate, the alternate ones 
convex. Metasternum arcuato-emarginate, the excavation very deep, closed behind, reaching as far as 
the posterior margin of the middle coxe. 
Length 23, breadth 13 millim. (2.) 
Hab. Mexico, Chilpancingo (H. H. Smith). 
One specimen. More shining than its allies, the head sulcate between the eyes, the 
rostrum (2 ) comparatively smooth, the prothorax binodose on the disc and with acute 
lateral tubercles, the elytra faintly and irregularly albo-bifasciate,
