LAMPROSOMA. . 181 
emarginate; the eyes very fecbly notched; antenne black, the first joint partly fulvous below ; thorax 
punctured like the head ; elytra moderately convex, their apex broadly rounded, the disc finely punctate- 
striate. 
Hab. Guatemata, Santa Ana on the Rio Negro (coll. Jacoby). 
The broadly ovate, scarcely narrowed shape, the blue underside and legs, and the 
broad and deeply excavated prosternum distinguish Z. wnicolor from all the other 
species of the genus here enumerated. A single specimen, received from the Stuttgart 
Museum. 
36(r). Lamprosoma aterrimum. 
Very convex, narrowed posteriorly, entirely black ; head and thorax finely and sparingly punctured ; elytra 
very finely punctate-striate, the interstices smooth; prosternum scarcely longer than broad, flat. 
Length 24 lines. . 
Hab. Nicaraaua, Chontales (Janson). 
Of an entirely black colour, and therefore easily distinguishable from any other 
species of the genus. The head is very finely and remotely punctured, the anterior 
margin of the epistome moderately emarginate ; the thorax is only visibly punctured 
near the median lobe, the latter itself being rather rounded; the elytral punctuation is 
only visible under a strong lens; the prosternum is somewhat rugose in front, for the 
yest smooth and shining. If looked at sideways, the greatest convexity of the elytra is 
at the base. A single specimen. 
Lamprosoma minutum (p. 103). 
To the localities given, add :—MExico, Teapa in Tabasco (H. H. Smith); GUATEMALA, 
Cerro Zunil, Cahabon (Champion), Coban in Vera Paz (Conradt). 
Lamprosoma godmani (p. 104). 
To the Guatemalan locality given, add :—Paraiso (Champion). 
42 (a). Lamprosoma atro-violaceum. 
Ovate, distinctly narrowed posteriorly, black; head minutely granulate, greenish ; thorax black, extremely 
finely punctured ; elytra blackish-violaceous, distinctly punctate-striate at the base, the apex almost 
impunctate. 
Length 3 line. 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
This small species differs from LZ. godmant in being more narrowed posteriorly and 
in having the head very finely granulate. The head is sometimes black, frequently 
metallic greenish, with a fine longitudinal groove down the centre. The elytra have a 
violaceous or bluish tint, and the punctuation is only distinct near the base, and 
almost entirely obliterated below the middle; in LZ. godmani the punctures are distinct
