EUVIRA. 279 
The species are apparently numerous in Central America; but I am not acquainted 
with any from other regions; they are apparently very similar to one another, and will 
be difficult to discriminate. 
1. Huvira nigra. 
Nigra, antennis flavis, articulo ultimo nigricante ; capite dense fortiterque punctato ; prothorace convexo, parvo, 
elytris quam hic multo longioribus; abdomine crebre substrigoso-punctato. 
Long. 12 millim. 
Hab. Nicaracva, Chontales (Janson). 
Antenne yellow, with the terminal joint dark, and the preceding one somewhat 
infuscate, short; third joint short, much shorter than the second ; fourth to tenth each 
a little broader than its predecessor, all short, the first two or three of them quite 
small, the penultimate joints strongly transverse; terminal joint stout, obtuse. Head 
small, only about half as broad as the elytra, convex, very coarsely punctate. Thorax 
strongly transverse, a little narrower than the elytra, the front angles greatly depressed, 
surface coarsely punctate. LElytra rather coarsely punctate. Hind body parallel, with 
a rather close and regular peculiar punctuation, consisting of fine longitudinal eleva- 
tions. Legs black, the tarsi fuscous. | 
In the male there are no impressions on the head or thorax, but the seventh dorsal 
plate bears a few rough granules; this plate is small, and has its hind margin rounded. 
I have had six specimens of this species for examination; the dark legs and the 
yellow antenne with only their extremity dark appear to be constant characters. 
2. Euvira longula. 
Sat elongata, angustula, parallela, nigra, antennarum dimidio basali flavo, tibiis tarsisque fusco-testaceis ; 
capite dense fortiterque punctato ; prothorace convexo, parvo, elytris quam hic multo longioribus ; abdomine 
erebre substrigoso-punctato. 
Long. 27 millim. 
Hab. Muxtico, Jalapa (Hoge); Guaremaa, Cerro Zunil 4000 to 5000 feet (Champion). 
Antenne short and stout; the five basal joints yellow, the others dark, the basal 
joints rather stout, the fourth and fifth not slender. 
In the male the upper surface of the head is flat on the middle; the sixth dorsal 
plate is rather closely covered with fine, elongate granules, and the seventh bears more 
conspicuous granules; the hind margin of the latter is truncate in the middle. 
The species differs from £. nigra by the more elongate form, by the thicker basal 
portion of the antennz, by the fact that these have a larger number of joints dark, and 
by the flattening of the upper surface of the head in the male. 
The two individuals found by Hoge are in bad condition, and their punctuation is 
consequently obscure. From Cerro Zunil there is only a single female; and under 
these circumstances some doubt must exist whether it be really the same species.
