is obsolete. The serial punctures of the elytra are very fine, but more distinct at the 
base. The griseous hair on the femora is not conspicuous. 
The specimen described is no doubt a male, the middle tibia being incurvate at the 
apex; the first ventral suture is quite deep. A very immature example found by 
Conradt at Coban in Guatemala may perhaps be referable to this species. 
4. Hemilypus obliteratus, sp. n. (Tab. I. fig. 23, var.) 
Niger, nitidus, capite cyanescente, antennis fusco-rufis; supra parcissime setosus, pedibus corporeque ad 
margines albido-pilosis ; elytris subtilissime remoteque scriatim punctatis. 
Long. cum rostro 43 millim. 
Hab. Panama, Bugaba (Champion). 
Var.? an mas? antennarum clava valde elongata, articulo ultimo elongato. 
Hab. Panama, Volcan de Chiriqui 4000 feet (Champion). 
Antenne rather long, obscure red, the terminal joint slightly longer than the tenth. 
Rostrum broad, very short, not longer than the head; eyes not very large, the space be- 
tween them, also the vertex, finely punctate. Thorax longer than broad, a little rounded 
at the sides, sparingly punctate. Scutellum small, with white pubescence. Elytra with 
very obliterated series of punctures; the punctures are quite fine, even at the base, and 
at the apex can scarcely be detected. The white pubescence on the legs is very 
conspicuous. 
Two examples: in one the blue colour of the head is not very distinct. I suspect 
the specimen with long antenne may be a male of another species, but it may be only 
a variety ; it is in beautiful condition, and we figure it. 
5. Hemilypus ——? 
Hab. Guatemaa, Cerro Zunil 4000 feet (Champion). 
A species closely allied to H. obliteratus, but evidently distinct, is represented by a 
single example that is too immature for description. 
ESSODIUS, gen. nov. 
Rootrum elongatum, tenue, curvatum. Caput post oculos haud constrictum. Prosternum epimerorum apicibus 
haud conjunctis. Abdomen sutura prima ventrali obsoleta. 
This genus is established for an anomalous Rhynchitid, agreeing with Lugnamptus 
in the prosternal structure, but differing greatly therefrom in the form of the rostrum 
and head, and possessing a much shorter basal joint on the feet. So that if Hssodius 
be not separated, I do not see how Eugnamptus could be defined.
