CONOSOMA. 313 
Thorax black, with a sharply defined border of yellow at the side and base, this border 
being broadest at the hind angles. Elytra black, behind with a waved margin of 
yellow colour; this is broad at the outer margin, just within this still a little broader, 
then becomes narrower towards the suture.

This genus is of almost cosmopolitan distribution, and will no doubt prove to be very 
rich in species ; at present about seventy species pertaining to it are described. The 
name Conurus has priority ; but as it is in use in ornithology, it should give place to 
Conosoma. | 
1. Conosoma gravidum. (Tab. VII. fig. 14.) 
Latius, convexum, ferrugineum ; capite, thorace, elytris antennisque fuscis, his articulis quatuor basalibus pedi- 
busque testaceis ; thorace elytrisque minus dense punctatis, his ad basin ferrugineis ibidemque aureo- 
setulosis ; abdomine aureo-setuloso, setis exsertis haud elongatis. 
Long. 53 millim. 
Hab. Panama, Bugaba, Volcan de Chiriqui 2000 to 3000 feet (Champion). 
Antenne rather short, much thickened towards the extremity, so that the tenth 
joint is rather strongly transverse ; extremity of the terminal joint yellow. Thorax 
dark in colour, more or less red at the sides and hind angles, the latterrounded. Hind 
body ferruginous, fifth and sixth segments black at the base, seventh dark behind; 
it is closely punctate. Mesosternum distinctly carinate ; the posterior division of the 
carina short, coarsely punctate. 
This species is allied to C. datum from the Amazons, but differs in numerous details 
of the coloration and clothing of the surface. Only two individuals have been found. 
2. Conosoma plebeium. 
Elongatum, subopacum, dense punctatum, fuscum ; antennarum basi pedibusque testaceis ; antennis gracilibus 
articulis nullis transversis ; prothorace elongato, basi utrinque sinuato, angulis posterioribus rectis, vix 
minute rotundatis. 
Long. 6 millim. 
Hab. Guatemata, Cerro Zunil 4000 to 5000 feet (Champion). 
Antenne elongate and slender; tenth joint a good deal longer than broad ; terminal 
joint a little longer than the tenth, pale at the apex; the two or three basal joints 
yellow, the others more or less deeply infuscate yellow. Thorax elongate, the hind 
angles distinctly produced backwards; the surface very finely punctate and pubescent. 
The elytra though elongate are scarcely longer than the thorax; they are densely
