hand the Amazonian L. sobrina, Sharp, may possibly prove to be only a variety of 
L. limbata. The species of this immediate group are very similar to one another, and an 
examination of the cedeagus will be required before they can be satisfactorily determined. 
3. Lithocharis hilaris. (Tab. XIV. tig. 11.) 
Fusco-rufa ; capite nigro ; elytris abdomineque fuscis, his apicem versus argute testaceis ; prothorace antennisque 
rufis ; pedibus flavo-testaceis. 
Long. 5 millim. | 
Hab. GuaTEMALA, near the city, Torola, Zapote, Paso Antonio, San Gerdnimo, 
Cubilguitz, Lanquin (Champion); Panama, David, Tolé (Champion). 
Antenne rather stout, red, slightly clouded in the middle, the tenth joint as long as 
broad. Head rather large, subquadrate, black, shining. Thorax nearly as long as 
broad, the sides a little narrowed behind, the front margin on either side rather 
strongly oblique; the surface closely and finely punctate, with a smooth line along the 
middle indistinct in front, but broader behind. Elytra densely and finely punctate, 
nearly black, with the hind part yellow ; longer than the thorax. In the male there 
is a feeble emargination of the last ventral plate. 
4, Lithocharis discoidalis. 
Fusca; capite prothoraceque nigricantibus ; elytris testaceis, apice pallidiore, disco late infuscato; antennis 
pedibusque testaceis, illis brevibus apicem versus leviter incrassatis, articulis penultimis transversis. 
Long. 42 millim. 
Hab. Panama, Bugaba (Champion). 
This insect is very closely allied to L. ochracea, but is readily distinguished from it 
and the other allied species by the structure of the antenne; the colour of the thorax 
and elytra also is different from L. ochracea. The antenne are not so long as the head 
and thorax, and are clear, pale red; they are very slightly thickened towards the | 
extremity, and the penultimate four joints are each distinctly shorter than long. The 
head is quite as broad as the thorax, larger than in L. ochracea, very densely and finely 
punctate. The thorax is subquadrate, dull, very densely and finely punctate, with a fine 
smooth line along the middle. The elytra are more coarsely punctate than in L. ochracea, 
and their yellow colour is pallid at the apex, the disc being broadly infuscate. Only 
two examples were obtained, both apparently females.
