+ RHYNCHOPHORA. 
round fovea. Legs slender. Male with a depression along the middle of the ventral 
segments. 
We have received five examples of this species, which is allied to A. klug?, but 
differs in a great many minor points, besides the foveze on the wing-cases. Of the 
variety we have received only one specimen. It is quite possible that it may prove to 
be a distinct species. 
7. Attelabus diffinis, sp. n. 
Gracilis, nigerrimus, brevissime parcissimeque pubescens, subopacus; elytris obsolete sculpturatis. 
Long. cum rostro 9 millim. 
Hab. Mexico, Chilpancingo in Guerrero (H. H. Smith, June 1888). 
Head elongate, about as long as the rostrum, the eyes convex, very widely separated, 
the space between them without depressions, rugosely sculptured. Thorax elongate, 
rounded at the sides and a little narrowed in front, with a feeble depression or constric- 
tion in front of the base, the surface transversely rugose. Scutellum narrow and quite 
small. Elytra elongate, with a distant, very irregular punctuation. Legs long and 
slender. 
This insect has the form of A. klugi, but is very different in colour, sculpture, and 
pubescence. Only one example has been obtained; it is a female, and has the two 
spurs on the anterior tibize placed one in front of the other as in A. viridans. 
B. Eyes only moderately distant, the space between them carinate ; surface pubesceit ; 
spurs of the anterior tibie of the female placed one above the other. (Himatolabus, 
Jekel.) 
8. Attelabus vestitus. 
Attelabus vestitus, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 307’. 
Hab. Mexico, between Oaxaca * and Acapulco !, Oaxaca (Hége), Yolos (Sadlé). 
Var. duplo minor. 
Hab. Mexico, Ciudad in Durango, Zacualtipan in Hidalgo (/ége). 
The sexual distinctions, except in the front legs, are not conspicuous in this species ; 
the female has the armature of these parts very strongly developed, the upper of the 
two apical mucrones being of unusual size. 
The unique exponents from Ciudad and Zacualtipan may not be really conspecific ; 
they by no means agree with one another, however, and if distinct from 4. vestitus 
must represent two closely allied species. 
* Schonherr writes in this and other cases “‘ Oaxara”; but as there can be little doubt that Oaxaca is intended 
I shall make this change whenever I have occasion to quote the locality from him.
