Rotundato-ovalis, sat convexa, testacea, capite nigerrimo, pectore abdomineque nigricantibus ; elytris subtilissime

Hab. GuaTEMALA, near the city (Champion). 
So far as I may judge from the solitary individual before me, this species is closely 
allied to the Californian C. pallida, Lec., but is rather larger and a little more elon- 
gate, and of brighter colour, the prothorax being clear yellow, without any trace of 
infuscation. The legs are very stout. 
2. Chetarthria punctulata. 
Rotundato-ovalis, convexa, nigra; antennarum basi, palpis pedibusque rufis, prothorace elytrorumque apice 
picescentibus ; elytris crebre subtiliter punctulatis et pubescentibus, punctis ad basin sparsioribus, stria 
suturali profunda ante basin desinente.

Hab. Mexico, Cordova (Sailé). 
I have seen but a single badly preserved individual of this species ; but it appears 
very distinct by the evident punctuation of the elytra, the punctures towards the apex 
being rather close and each bearing a rather fine hair. | 
3, Chetarthria glabra. 
Subglobosa, nigra, nitidissima, impunctata, prothoracis elytrorumque margine picescente ; pedibus rufis, antennis 
palpisque testaceis, elytris. stria suturali vix dimidiata.

Hab. Nicaragua, Chontales (Janson). 
This little insect is distinguished by its extremely polished impunctate surface and 
the short sutural stria, which does not extend halfway to the base of the wing-case. 
4. Chetarthria leticula. 
Breviter ovalis, convexa, supra picescens, limbo dilutiore; antennis, palpis pedibusque testaceis ; elytris posterius 
subtiliter punctatis, stria suturali dimidiata. 
Long. ? lin. 
Hab. Guatemaa, San Gerénimo (Champion). 
In this minute insect the punctuation of the wing-cases is more distinct than it is in 
the other Central-American Chetarthrie, with the exception of C. punctulata, but it is 
not so coarse as in the European C. seminulum. The sutural stria becomes gradually 
obliterated in front, but may be traced for one half of the length of the wing-case. The 
colour of the under surface is even brighter than that of the upper, the breast being 
reddish yellow.
