RHYNCHITES. 19 
7. Rhynchites mollis, sp. n. 
Niger, longius parciusque grisco-hirtus ; capite sat lato, rostro fortius rugoso ; prothorace subcylindrico ; elytris 
seriatim fortiter punctatis, interstitiis haud omnino planis. 
Long. cum rostro 4 millim. 
Hab. Mexico, Oaxaca, Zacualtipan in Hidalgo (Hége). 
Antenne short, with short, extremely broad club. Thorax small, subcylindrical, 
very slightly curved at the sides, closely and coarsely punctate, the punctuation on the 
disc less. Scutellum quite narrow. Elytra with regular series of closely placed coarse 
punctures, the interstitial punctures few and obsolete. In the female the rostrum is about 
as long as the head and thorax, the antenne are inserted a little behind the middle of 
the rostrum, and the rostrum is not so coarsely rugose in front. In the male the 
rostrum is considerably shorter, the antenne are inserted just in the middle, and the 
eyes are larger, so that the head is broader. Seven specimens. 
A distinct species, easily recognized; the erect pubescence appears in certain lights 
quite white. 
8. Rhynchites scutellaris, sp. n. 
Nigerrimus, nitidus, nigro-hirtus, scutello albido-piloso, corpore subtus griseo-pubescens ; capite prothoraceque 
parce punctatis ; elytris seriatim punctatis, interstitiis seriatim remote punctatis. 
Long. cum rostro 34-44 millim. 
Hab. GuateMata, Capetillo (Champion). 
Var.(?) Major, elytris fortiter punctatis, interstitiis haud omnino planis. 
Hab. Mexico, Juquila ({ége). 
This species is closely allied to R. mollis, but on the upper surface the pubescence 
does not appear white, except that the scutellum is more densely clothed with long 
white hairs parted along the middle ; the punctuation of the head and thorax is much 
scantier; on the elytra the serial punctures become quite fine on the posterior half— 
they consist of a large puncture alternating with a very fine puncture—and the broad, 
quite flat interstices bear also a few fine setigerous punctures. The rostrum is coarsely 
sculptured ; the space between the eyes is impunctate, except laterally; and the vertex, 
like the slender thorax, is moderately finely, not closely punctate. Four specimens. 
The example from Juquila that I have treated as a variety will, I think, prove to be 
distinct. 
9. Rhynchites basalis, sp. n. 
Nigerrimus, supra haud dense hispidus, nitidus; prothorace elongato, cylindrico, parce punctato; elytris 
seriatim punctatis, punctis in parte posteriore omnino subtilibus, ad basin fere grossis. 
Long. cum rostro 33 millim. 
Hab. Panama, Bugaba (Champion). 
A species similar to £&. mollis, but easily distinguished by the cylindrical thorax
