18 RHYNCHOPHORA. 
nearly as long as broad, sparingly punctate. LElytra with series of moderately distant, 
not coarse punctures, and with the interstices sparingly and finely seriate-punctate. 
The construction of the club of the antenne in the male is very peculiar: the ninth 
joint is quite as long as broad, the tenth is rather longer, and oblique at its extremity, 
while the terminal joint is small and placed on the oblique truncature, so that in 
certain positions it has the appearance of being inserted on the posterior aspect of the 
preceding joint (fig. 17 a). Four examples, three males and one female. 
5. Rhynchites leticulus, sp. n. 
Yiridi-auratus, nitidissimus, parcissime breviter hispidus, rostro, antennis pedibusque nigris; prothorace par- 
cissime punctato; elytris seriatim grosse punctatis. 
Long. cum rostro circiter 5 millim. 
Hab. Mexico, Chilpancingo and Acapulco in Guerrero (Hége). 
Club of the antenne short, broad, very abrupt. Rostrum with a few coarse longitudinal 
rugee. Head narrow, with an impression between the eyes, very sparingly punctate in 
front, impunctate behind. Thorax narrow, about as long as broad, slightly rounded 
at the sides, very sparingly punctate, with a fine abbreviated channel on the disc. 
Scutellum narrow. Elytra with series of very large punctures, and with a few minute 
punctures on the interstices. In the female the rostrum is slightly longer than the 
head and thorax ; in the male it is a little shorter. 
This brilliant little insect has a very small amount of sculpture on the thorax and 
is very scantily setiferous on the wing-cases. We have received only three examples. 
6. Rhynchites subauratus, sp. n. 
Viridis, supra auratus, nitidus, hispidus, rostro antennisque nigris, pedibus nigro-viridis ; vertice prothoraceque 
profunde punctatis; elytris seriatim fortiter punctatis, interstitiis parce punctatis. 
Long. cum rostro 34—4 millim. 
Hab. Mexico, San Luis Potosi, Saltillo in Coahuila (Palmer), Guanajuato (Sal/é). 
Var. Minus lete auratus, prothorace densius punctato, rugoso. 
Hab. Mexico (Truqui). 
Allied to &. leticulus, but smaller, differently sculptured, and more densely hispid. 
Head without depression between the eyes, coarsely, deeply, and closely punctate. 
Thorax small, slightly rounded at the sides, very coarsely punctate. Elytra clothed 
with long, erect, not dense, hairs, and bearing regular series of coarse deep punctures, 
aud with a scanty, rather coarse, punctuation on the interstices. 
The two examples from Guanajuato and the single one from San Luis Potosi agree 
well with each other; the single specimen from Saltillo is a female of large size, with 
rather more scanty punctuation, but is, I expect, referable to the same species. The 
individual found by Truqui may be distinct.
