ATTELABUS. 3 
Antenne very short, the fourth joint a little longer than broad, the sixth about as long 
as broad, the seventh and eighth transverse, the club abrupt, compact, about as long 
as the five preceding joints, the tenth joint rather shorter than the ninth or eleventh. 
Rostrum short and broad, only as long as the head; eyes prominent, widely separated, 
the surface between them rugose. Thorax narrower in front than behind, constricted 
both in front and at the base. Elytra with a series of deep punctures, subrugose, not 
brilliant even at the apex. 
We have received only two female examples of this species. One of the varieties of 
A. viridans is almost similarly coloured, but I separate A. smitht on account of its 
smaller size and still coarser and deeper sculpture. The cupreous-red parts of A. smithi 
are duller in colour than in A. swmptuosus and A. viridans, var., and the legs have 
scarcely any metallic tint. 
4. Attelabus splendens. (Tab. I. fig. 2, ¢.) 
Attelabus splendens, Gyll. in Schéuh. Gen. et Spec. Cure. v. p. 304". 
Hab. Mexico, Vera Cruz (Chevrolat !, Sallé). 
I have seen only two examples of this species. The female has the front tibie 
bimucronate, the mucrones being placed similarly to those of the same sex of A. vir- 
dans and A. sumptuosus; the mucrones, however, are much smaller in A. splendens, 
and the tibia is shorter and stouter and the crenulations on its inner face are much 
less marked. The male is in an immature and mutilated condition, and has onlya 
single small mucro on the front tibie. 
5. Attelabus klugi, (Tab. I. fig. 3,4.) 
Attelabus klugii, Gyll. in Schénh. Gen. et Spec. Cure. v. p. 302°. 
Hab. Mexico (Klug), Parada (Sal/é). 
6. Attelabus nigriclava, sp. n. 
Gracilis, eneus, rugosus, griseo-pubescens, antennarum clava nigerrima, elytris singulis puncto depresso fusco. 
Long. cum rostro 7 millim. 
Hab. Mexico, Chilpancingo in Guerrero 4600 feet (H. H. Smith). 
Var. Elytris minus profunde rugosis, quasi submaculatis; minus conspicue griseo-pubescens. 
Hab. Mexico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Antenne moderately long, the club abrupt, quite black and thus contrasting strongly 
with the other joints, as these bear much white hair. Head as long as the rostrum; 
eyes prominent, widely separated. Thorax much narrowed towards the front, but not 
constricted either in front or at the base, deeply transversely rugose. Scutellum 
narrow. Elytra rather deeply and coarsely rugose; on the middle of each is a small
