Genera and Species of Coleoptera. 483 
The three following genera comprise the species which are ex- 
cluded from Adelium as defined by M. Lacordaire, and which he has 
indicated as types of new ones, without, however, giving their 
characters. 
OrRINTUS. 
Characteres ut in Adelio; sed prothorax basi sinuatus. Elytra convexa, 
angustata, epipleuris verticalibus. Tvbie antic curvate. Mesosternum 
elevatum, cayvitate A-formi pro receptione processus prosterni. 
Type, Otrintus Behrit, Germar (Prosodes ?). 
CorIPERA. 
Characteres ut in Adelio; sed elytra prothoraci arcte applicata; epipleuris 
angustatis, humeris distantibus. 
Type, Coripera deplanata, Boisduval (Adelium). 
PHELONEIS. 
Characteres ut in Adelio; sed antenne articulis apicalibus, ultimo excepto, 
transversis. Elytra prothoraci arcte applicata. Tarst antici et inter- 
medii articulis, ultimo excepto, plus minusve latioribus, et triangulariter 
transversis. 
Type, Pheloneis harpaloides, White (Adelium). 
To any of these it is impossible to refer Adelium catenulatum, 
Boisd. It has the elytra closely applied to the prothorax as in 
Coripera and Pheloneis ; but the epipleuree mounting to the shoulder 
as in Adelium cuts it off from the former, while the latter has the 
terminal joints of the antenne dilated, and an entirely different 
habit, singularly resembling, as M. Lacordaire observes, certain 
Amaras. It may be named 
SEIROTRANA, 
Chiracteres ut in Adelio, sed elytra prothoraci arcte applicata. Antenne 
articulo tertio duobus sequentibus breviore. 
Type, Sedrotrana catenulata, Boisduval (Adelium). 
Cympesa [ Helopine |. 
Caput breve, retractum ; clypeus distinctus, ultra basin antennarum haud 
productus, apice rotundatus. Labrum angustatum, productum. Mentum 
transverse cordatum. Palpi ut in Adelio. Antenne lineares, art. tertio 
longiore, ultimo ovato. Prothorax transversus, lateribus vix rotundatus, 
leviter marginatus, apice late sinuatus, basi in medio retractus, angulis 
posticis rotundatis. Scutellum transversum. Elytra basi prothorace 
vix latiora, apicem versus sensim angustiora, lateribus subito declivia. 
Pedes ut in Adelio, Prosternum postice productum in cavitate meso-
