OOMORPHUS.—CHRYSODINA. 183 
Lamprosoma in the short eighth joint of the antenne and in the simple claws. The 
two species from Central America referred to it seem to possess these characters, as 
well as wings, and they are of somewhat more elongate shape than their Old-World 
congeners, 
1. Oomorphus mexicanus. 
Oblong, subcylindrical, dark neous ; the basal two joints of the antenne fulvous; head and thorax almost 
impunctate; elytra finely punctate-striate, greenish-zeneous. 
Length ? line. 
Head entirely impunctate; eyes entire; antenne extending to the base of the thorax, black, the lower two or 
three joints fulvous ; thorax more than twice as broad as long, the sides straight but slightly converging 
towards the apex, the base oblique on each side and with the median lobe scarcely pointed, the surface 
exceedingly finely punctured (the punctuation only visible under a very strong Jens) ; scutellum scarcely 
visible; elytra cylindrical, very little narrowed posteriorly, not lobed at the sides, the punctuation 
fine but distinct, but stronger at the base than near the apex, the interstices also with some minute punc- 
tures; underside blackish-zeneous ; the prosternum broad, a little longer than wide, and longitudinally 
sulcate throughout its entire length; abdomen finely pubescent. 
Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith). 
The unnotched eyes and the absence of a lateral lobe to the elytra, together with the 
‘subcylindrical shape, will help to distinguish O. mexicanus from any species of 
Lamprosoma. 
2. Oomorphus hirtipes. 
Oblong, black; above and the prosternum and tibie dark eneous; antenne obscure fulvous, the apical joint 
black; head and thorax finely punctured ; elytra strongly punctate-striate; tibiee with long grey hairs; 
prosternum quadrate. 
Length 13 line. 
Hab. Panama, Volcan de Chiriqui ( Champion) 
Much larger and more robust than 0. mexicanus ; the head extremely finely granulate 
and punctured ; the eyes entire; the antenne differently coloured; the elytra much 
more strongly punctured and with smooth interstices; the tibie and the prosternum 
obscure seneous, the former with a long fringe of greyish hairs along their outer edge. 
A single specimen. 
CHRYSODINA (p. 105 ) 
3 (a). Chrysodina servula. 
Chrysodina servula, Lefévre, Bull. Soc. Ent. Fr. 1887, p. clv’. 
Hab. Mexico, Atoyac in Vera Cruz (H. H. Smith); Costa Rica, Cache (Hogers) 
Panama, Bugaba, Volcan de Chiriqui (Champion *). 
Closely allied to C. festiva ; but differing from it in the unicolorous and much les 
deeply punctured head (in C. festiva the space above the insertion of the antenne and 
part of the epistome is metallic blue), and in the much broader prosternum. Many 
specimens, including the type.
