and the peculiar punctuation of the wing-cases, the punctures on the basal portion 
of the latter being very large, while nearer the apex they are as minute as the inter- 
stitial punctures. ‘The head and thorax are only sparingly punctate, and the pallid 
pubescence on the scutellum is not conspicuous. On the under surface the elongate 
pubescence is partly white. Two examples. 
10. Rhynchites auletoides, sp. n. 
Nigerrimus, nitidus, sublevigatus, parcius hispidus. 
Long. cum rostro 3 millim. 
Hab. GUATEMALA, Duefias (Champion). 
Rostrum rugose, not so long as the head and thorax. Antenne short, with broad, rather 
long club. Head rather broad, with only a few distant, extremely fine punctures, very 
shining. Thorax slender, cylindrical, longer than broad, remotely, very finely punctate. 
Elytra broad and short, with the punctuation very fine and remote, but consisting 
nevertheless of a serial punctuation, and of a serial interstitial punctuation still finer 
and more remote. Five specimens. I observe no distinction that I can consider 
sexual. 
§ 2. Pygidium entirely exposed ; rostrum obsoletely sculptured, but kttle curved ; eyes 
widely separated ; size very small. (Allies of the European R. nanus.) 
11. Rhynchites regularis, sp. n. 
Mneus, densissime fortiter punctatus, minus nitidus, glaber, rostro nigro; elytris fortiter denseque seriatim 
punctatis, interstitiis sat convexis. 
Long. cum rostro 3 millim. 
Hab. Mexico, Zacualtipan in Hidalgo (Hége). 
Rostrum black, punctulate. Vertex witha silky opacity, finely punctulate; eyes 
moderately distant, separated from the thorax by a considerable space. Thorax 
elongate, rounded at the sides and narrowed in front, extremely densely and coarsely 
punctured. Elytra with very regular series of deep, coarse punctures, which are 
scarcely, if at all, finer at the extremity; the interstices are narrow, somewhat elevated, 
scarcely pubescent. 
Of this little insect, remarkable on account of its greatly developed sculpture, we 
have received only two specimens. 
12. Rhynchites confertus, sp. n. 
/Eneus, dense punctatus, minus nitidus, pube depressa tenuiter vestitus ; rostro minus elongato, vertice lato. 
Long. cum rostro 3 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Antenne slender, with rather long slender club. Rostrum short, broad, black, feebly
