316 STAPHYLINIDA. 
7. Conosoma diffine. 
Haud elongatum, nigro-fuscum ; antennis pedibusque fuscis, illis basi et apice testaceis; prothorace basi trun- 
cato, haud breviore quam elytra. 
Long. 34 millim. 
Hab. GuateMaLa, Capetillo (Champion). 
Antenne not elongate, the penultimate joint about as long as broad. Thorax much 
narrowed in front, very finely punctate. lytra not longer than the thorax. Meso- 
sternal carina only slightly elevated. 
The three individuals found of this species are in very bad condition, and are very 
similar to the C. fusculum of Europe. | 
BOLITOBIUS. 
Bolitobius, Mannerheim, Brach. p. 18 (1830) ; Steph. Ill. Brit. Ent. v. p. 171 (1832).

This genus is moderately numerous in species (probably about fifty are known), 
and occurs throughout the northern and temperate regions of the northern hemisphere. 
A species from Rio de Janeiro has been ascribed to the genus, as well as another from 
the Antilles, and there is also a record of a species in Ceylon. The Colombian B. 
seriatus, Er., should probably be assigned to Megacronus, which genus Erichson did not 
distinguish from Bolitobius. Two of the Central-American species are of the most 
ordinary form of the genus, but the third, B. festivus, will probably be entitled to form 
a distinct genus. 
1. Bolitobius festivus. (Tab. VII. fig. 16.) 
Nitidus, rufo-testaceus ; antennarum articulis 5°-11™, elytrorum apice abdomineque nigris, hoc apice testaceo ; 
corpore anterius fere levigato, abdomine parce, segmento 5° densius, punctato. 
Long. 9 millim. 
Hab. GuATEMALA, Zapote (Champion); Panama, Volcan de Chiriqui 2000 to 3000 
feet (Champion). 
Head broad and short (for a Bolitobius) ; antenne with the penultimate joints rather 
shorter than broad. Thorax about as long as broad. Elytra longer than the thorax, 
very polished, along the suture with a series of five or six fine setigerous punctures, 
with a discoidal series of three or four distant, obsolete punctures, and with a marginal 
series of more crowded punctures. Hind body intense black; the hind margin of the 
fifth and the whole of the sixth and seventh segments yellow; the fifth segment is 
much more punctate than the others, and densely armed with sete and pubescence. 
The individual drawn is from Panama: the artist has represented the Species as 
much more slender than it really is; it should, indeed, be considerably broader than 
B. obliquus.
