at the base; coarsely punctate-striate, the interstices rugulose, the alternate ones raised. Metasternal 
excavation reaching to the apex. Legs short; posterior femora moderately incrassate; anterior and 
intermediate tibie angularly dilated near the base externally. 
Length 23-22, breadth 14-15%, millim. (@.) 
Hab, Muxico (Hoge, in coll. Solari); Panama, Caldera in Chiriqui (Champion). 
Two specimens, the one from Chiriqui being taken as the type. ‘The very 
long, comparatively smooth rostrum, the coarsely punctate-striate elytra, the form 
of the anterior and intermediate tibie, and the quadrinodose prothorax separate 
H. chiriquensis from its immediate allies. 
12. Hypoceliodes angulatus, sp. n. 
Short ovate, moderately shining, piceous, the antenne and tarsi ferruginous; clothed with scattered, minute, 
whitish scales, which are seriately arranged on the elytra and in part hidden by a fulvous mealy 
secretion. Head rugulosely punctate, feebly carinate on the vertex, without trace of superciliary ridges ; 
rostrum arcuate, stout, reaching the apex of the metasternum, shining, sparsely, rather coarsely punctate, 
rugose at the base, smooth along the middle. Prothorax rapidly narrowing from the base, constricted in 
front; densely rugosely punctate, canaliculate and feebly binodose on the disc, the dorsal elevations 
separated from the small lateral tubercles by an oblique groove. Elytra deeply punctate-striate, the 
interstices somewhat asperate and all more or less raised, the alternate ones more prominent than the 
others. Metasternal excavation deep. Legs short and rather stout; anterior and intermediate tibie 
angularly dilated, and the posterior tibie slightly widened, near the base. 
Length 23, breadth 14 millim. (9.) 
Hab, Panama, Bugaba (Champion). 
One specimen. The angularly dilated tibia, long stout rostrum, feebly quadrinodose 
prothorax, and deeply punctate-striate elytra, with raised interstices, sufficiently distin- 
guish //. angulatus. The rostrum is stouter and much more distinctly punctate than 
in the same sex of ZT. chiriquensis, and the alternate elytral interstices are less raised. 
AULEUTES. 
Auleutes, Dietz, Trans. Am. Ent. Soc. xxiii. pp. 390, 402 (1896). 
The various species referred to this genus, which includes ten N.-American forms 
and the holarctice A. epilobit (Payk.), are closely related to Hypoccliodes (Orchesto- 
merus), but have relatively less thickened posterior femora. The second ventral 
segment is short and acutely produced on each side posteriorly; the funiculus is 
7-jointed*; the rostral canal extends to the meso- or metasternum, and in some 
species is very deep and closed-in behind; the femora are unarmed and more or less 
sulcate beneath; the tibie are rounded at the base externally; and the claws are 
toothed. Most of the Mexican and Central-American forms are nearly related to 
_A. nebulosus (Lec.): A. megalops has very large eyes, but agrees in other respects; 
A. inermis wants both the dorsal and lateral prothoracic tubercles, while in 
* Dietz includes two species with a 6-jointed funiculus, but these may have to be removed.
