Mr. Kirpy’s Century of Insects. 447 
minutissime rugulosus, cupreo-auratus, dorso elevato bilobo: 
lobis emarginatis, antice constrictus, postice lobatus, lobo bifi- 
do. Coleoptra quadrata, tuberculato-muricata: tuberculis sub- 
trigonis, anticis acutis, reliquis obtusis anterius excavatis: su- 
turis denticulatis, lateribus profunde sinuata. Sternum ele- 
vatum, os claudens. femora subtus cuprea, pro receptione ti- 
biarum longitudinaliter excavata. Anus inflexus. Segmenta 
antica brevissima, et quasi plicata, anali profunde excavato. 
This species seems to differ from the others of the genus. in the 
structure of its labial. palpi, since they are not at all furcated. 
Whether the other species have the sutures denticulated I do not 
know, having only this species of the genus. Olivier does not no- 
‘tice it. The circumstance is so unique and rémarkable, that if 
they have it not, it would indicate that C. Bacca belongs to a 
- distinct genus. 
(Choragide.) 
Cuoracus Kirby. 
Palpi subsetacei : articulo extimo acuto. 
Antenne clavatæ: clava triarticulata, basi afticulis duobus pri- 
mis incrassatis. 
Corpus cylindricum. 
Caput inflexum : clypeo elongato. 
After repeated examinations under a powerful magnifier, I have 
not been able clearly to discover more than three joints in the 
tarsi of this insect; but Mr. Curtis in one tarsus detected four. 
Indeed its general habit, &c. connect it witb the Tetramera, espe- 
cially Cis and Cryptocephalus : it will not however well arrange 
under any of the present families of that section of Coleoptera; I 
have therefore considered it as the type of a new one, to which 
some other nondescript genera in my cabinet belong.
