LITOLIBRUS. 259 
species are numerous in our region I am not acquainted with any belonging to it from 
other parts of the world, and it is probable it may prove to be peculiar to Tropical 
America. 
1. Litolibrus obesus, sp. n. (Tab. VII. fig. 24.) 
Hemisphericus, nitidus, testaceus; elytris plus minusve rufo-tinctis, stria suturali seriebusque subtilibus 
punctorum, et stria et punctis anterius desinentibus ; antennarum clava elongata. 
Long. 4-5 millim. 
Hab. Guaremana, El Tumbador, Las Mercedes, Cerro Zunil, San Isidro, Mirandilla, 
Sinanja, Chacoj (Champion); Panama, Bugaba, Volcan de Chiriqui below 4000 feet 
(Champion). 
Eyes very large. Penultimate two joints of antenna each about as broad as long, 
the terminal joint nearly twice as long as wide. Thorax very broad, faintly lobed in 
the middle, with the base very finely margined. Scutellum moderately large, about 
as long as broad. Elytra with broad flat basal margin. 
The elytra in this species are iridescent in certain lights, and in some specimens are 
red, in others similar in colour to the thorax. 
In Guatemala only single examples were procured in each of the above localities ; in 
the State of Panama the insect was obtained in moderate numbers, but the specimens 
are unfortunately very much decayed. 
9. Litolibrus cinctus, sp. n. 
Hemispheericus, testaceus ; elytris rufis, nigro-cingulatis ; prothorace nigro, utrinque macula magna testacea. 
Long. 33 millim. 
Hab. Panama, Bugaba (Champion). 
Terminal joint of antenna more than twice as long as the tenth. Elytra externally 
with a black band, this band connected with the black colour on the thorax so that 
a large discoidal red space is enclosed by a black girdle. Scutellum black. Extreme 
hind margin of the elytra yellow; punctuation obliterated, except behind, and there 
very indistinct. 
This species by its colour recalls certain forms of Coccinellide; it is, however, 
similar in structure to DL. obesus. Eight examples were procured, but they are 
unfortunately in a very mutilated condition. 
3. Litolibrus rufipennis, sp. n. 
Hemisphericus, testaceus, elytris rufis, capite prothoraceque fuscis limbo dilutiore. 
Long. 34 millim. 
Hab. Panama, Bugaba (Champion). 
Except in colour, this species seems very close to L. cinctus. The elytra are red,
