NEMOCEPHALUS. 7a 
apparently closely allied to WV. femoratus, labelled “ glabratus, Fabr.” NV. glabratus 
has, according to Schénherr, bisulcate elytra. 
2. Nemocephalus guatemalensis. (Tab. II. fig. 11, 2.) 
Nematocephalus guatemalensis, Senna, Bull. Soc. Ent. Ital. xxv. p. 128, t. 1. fig. 4°. 
Hab. Mexico, Playa Vicente (Sallé), Cordova, Las Vigas (Hoge); GuatTemaa ', 
Yzabal (Sailé), Tapachula (Hoge), San Gerénimo, Chaco}, and Teleman in Vera Paz 
(Champion); Nicaragua, Chontales (Janson) ; Panama, Volcan de Chiriqui (Champion). 
This insect is on the upper surface very similar to V. femoratus, but the punctuation 
of the elytra is quite obsolete, and this character suffices to distinguish both sexes from 
N. femoratus. On the under surface of the rostrum and head of the male NV. guatema- 
lensis is very different from N. femoratus, owing to the dense, fine punctuation and 
pubescence. ‘The species varies a good deal in numerous minor characters; the indi- 
viduals are usually of an intense black colour, but picescent specimens occur, and the 
examples described by Dr. Senna were of this colour. In both sexes the elytra are 
more distinctly bisulcate than in WV. femoratus. ‘The male has no trace of any femoral 
lamina. 
3. Nemocephalus punctulatus. 
Brenthus (Nemocephalus) punctulatus, Boh. in Schonh. Gen. Cure. v. p. 544°. 
Hab. Mexico (coll. Chevrolat +). 
I judge from the description that this species is allied to N. femoratus and N. guate- 
malensis, but the body beneath is said to be closely and deeply punctured. We have 
not received specimens of any species agreeing with this description, and there was no 
insect standing with this name in the Salle collection. In the British Museum 
collection there is a specimen labelled “ NV. punctulatus, Mexico ”; it appears to be an 
extremely small male of WV. guatemalensis. I do not think this could belong to the 
species described by Boheman as N. punctulatus. 
4. Nemocephalus deplanatus, sp. n. 
Subdepressus, piceus, politus ; oculis prominulis ; elytris seriatim regulariter subtiliter punctatis, medio versus 
suturam evidenter bisulcatis. 
Long. 11 millim. 
Hab. Nicaracua, Chontales (Janson). 
We have received only one individual, a male, of this species. On the upper surface 
it is extremely similar to some of the varieties of JV. guatemalensis, but it is very 
distinct by the sculpture of the under surface of the head and rostrum. The head and 
rostrum bear comparatively few hairs, and the former has fewer punctures ; these on 
the metarostrum become seriate, so that on each side there is a series of large confluent
