RHYNCHITES. 17 
near the City of Mexico Hége obtained a single example of very small size (long. 4¢ 
millim. incl. rostr.) and approaching in punctuation the Guatemalan &. distans. It is 
probable, however, that this latter variety may prove to be distinct. ‘The male of 
R. mexicanus possesses a peculiar sexual character that has not hitherto been noticed : 
on the posterior part of the suture of the elytra the erect hairs are more numerous, and 
are so placed as to form two short divergent rows on each of the margins of the elytral 
suture. In the males of the deeply striate varieties this character, however, does not 
exist. 
2. Rhynchites zunilensis, sp. n. (Tab. I. fig. 16.) 
Aineus, densissime punctatus, griseo-hispidus. 
Long. cum rostro 3 millim. 
Hab. GuateMaLa, Cerro Zunil 5000 feet (Champion). 
A very distinct little insect, allied to R. @neus, of which we have received only one 
specimen that is doubtless of the male sex. Antenne inserted at the middle of the 
rostrum, brassy-black, with short, very broad, and abrupt club. Rostrum about as long 
as the thorax, very rugose ; head coarsely, extremely densely punctate. Thorax small, 
scarcely so long as broad, very densely punctate. Elytra densely punctate, the serial 
punctuation scarcely distinguishable from the dense interstitial punctuation. Legs 
brassy-black. 
8. Rhynchites distans, sp. n. 
AEneus, vel cyaneo-seneus, rostro, antennis pedibusque nigris, nitidus, setis nigris erectis parce vestitus ; elytris 
seriatim distanter punctatis, interstitiis subtilius fere parcius punctatis. 
Long. cum rostro +—5 millim. 
Hab. Guaremata, San Joaquin and San Gerénimo in Vera Paz (Champion). 
Closely allied to &. eneus, but of much smaller size than the smallest varieties of 
that species, and with the elytra very differently punctuated and setose. In form and 
sculpture the head and rostrum are in each sex similar to those of the corresponding 
sex of R. wneus. The thorax is small, rounded at the sides, sparingly punctate, with a 
short, fine channel on the disc. Elytra with regular series of punctures, but with the 
punctures very far from one another, and with the interstices also serially punctate, the 
punctures being fine and even more distant than those of the series. Four specimens. 
4, Rhynchites abnormalis, sp. n. (Tab. I. figg. 17, 17 a, 3.) 
Niger, nitidus, parce hispidus ; elytris cyaneis, seriatim haud fortiter punctatis. 
Mas antennis articulis 9° et 10° longioribus, articulo ultimo parvo, asymmetrice sito. 
Long. cum rostro 4 millim. 
Hab. Mexico, Parada (Sallé), Oaxaca (Hoge). 
Eyes moderately distant, the space between them punctate-rugose. Thorax narrow,
