AULEUTES. 149 
constricted and much narrowed in front, finely punctate; the disc binodose and shallowly sulcate, the 
lateral tubercles moderately prominent, the anterior margin notched in the middle. Elytra deeply 
punctate-striate, the interstices finely asperate, the alternate ones raised. Mesosternum with a very 
prominent oblique ridge on each side between the middle coxe, the metasternum flattened or slightly 
depressed in front. Fifth ventral segment deeply foveate in the middle, and all the tibise unguiculate at 
the inner apical angle, in the ¢. 
Length 13-21, breadth 11-14 millim. (6 2.) 
Hab. Muxico (fége, in coll. Solari), Atoyac in Vera Cruz, Teapa (H. H. Sinith) ; 
GUATEMALA, San Gerénimo (Champion). 
Eight specimens. In this species the rostrum is almost straight, comparatively 
slender, and very much smoother in the female than in the male, and the apical 
portion of the rostrum is received between the two prominent mesosternal carine, the 
rostral canal not reaching the metasternum. 
7. Auleutes mexicanus, sp. n. 
Short ovate, dull, black, the antenne and tarsi, and sometimes the apical margin of the elytra also, ferruginous ; 
the vestiture fine and rather close, fuscous intermixed with cinercous, the cinereous scales clustered into 
small, scattered, faint patches on the elytra (but not extending on to the suture at the base), the under 
surface with coarser whitish scales. Head rugosely punctate; rostrum very stout, arcuate, a little 
longer than the prothorax, rugosely punctate and finely carinate. Prothorax constricted and much 
narrowed in front, densely, rather coarsely punctate, the apical margin notched in the middle, the dise 
binodose and shallowly sulcate, the lateral tubercles sharp, the ocular lobes rather prominent. Llytra 
punctate-striate, the interstices rugulose, the alternate ones conyex. Mesosternum somewhat deeply 
excavate, the metasternum also slightly depressed between the middle coxe. Fifth ventral segment 
with a large fovea in the ¢. Legs rather stout, the posterior femora thickened; intermediate tibiz 
strongly, and the posterior tibie feebly, unguiculate at the inner apical angle in the ¢. 
Length 21-24, breadth 13-1} millim. (¢ @.) 
Hab. Mexico, Omilteme, Chilpancingo, and Amula in Guerrero (H. H. Smith), 
Yolos in Oaxaca (Sallé). 
Six specimens. In this insect the elytra are faintly mottled with cinereous, the 
prothorax is quadrituberculate, the rostrum is very stout and rugose in both sexes, and 
the intermediate tibiz only of the male are sharply unguiculate. ‘The posterior femora 
are rather stout, and the species would be almost as well placed in //ypoceliodes, near 
H. phytobioides. 
8. Auleutes similis, sp. n. 
Very like A. mewicanus, but with the cinereous scales more abundant above, clustered on the elytra into 
various irregular, interrupted, undulate fasci# and a short streak at the base of the suture; the fifth 
ventral segment with a shallow transverse impression, and both the intermediate and posterior tibiw 
strongly unguiculate, in the ¢. 
Length 21-21, breadth 12-13 millim. (¢ 9.) 
Hab. Muxico, Xucumanatlan in Guerrero (H. H. Smith). 
-Three males and one female, apparently specifically distinct from <A. mexicanus, 
the male-characters differing in the two forms.
