Genera and /Species of Colc(jpt< r;i. 483 



The three following genera cc)ini)rise the species which are ex- 

 cluded from A<leVnim as deliiied by M. Lacordaire, and whicli h(! has 

 indicated as types of new ones, without, liowever, giving tlicir 

 characters. 



Otrintus. 

 C'liaractert's ut in Adelio; sed prothorax basi sinuatus. Ehjlta convcxa, 

 angustata, epipleuris verticalibus. Tihicc autic;e curvatai. Mcsoslcrnuin 

 olevatuni, cavitate A-fornii pro roeeptione processus prosterni. 

 Type, Otrintus BehrU, Gerniar (Prosodes ?). 



CORIPERA. 

 Characteres ut in Adelio; sed eli/fra prothoraci aicte applicata; cpiplcmis 



angustatis, humeris di stantibus. 

 Type, Conpera deplauata, Boisdiival (Adelium). 



Pheloneis. 



Characteres ut in Adelio ; sed antennce articulis apicalibua, ultimo excepto, 

 transversis. Bhjtra prothoraci arete applicata. Tarsi antici et iuter- 

 medii articuliS; ultimo excepto, plus minusve latioribus, et triangularitcr 

 transversis. 



Type, Pheloneis harpaloides, White (Adelium). 



To any of these it is impossible to refer Adelium catemdafum, 

 Eoisd. It has the elytra closely appKed to the prothorax as in 

 Goripera and Pheloneis ; but the epipleurai mounting to the shoulder 

 as in Adelium cuts it off from the former, while the latter has the 

 terminal joints of the antennae dilated, and an entirely different 

 habit, singularly resembling, as M. Lacordaire observes, certain 

 Amaras. It may be named 



Seirotrana. 

 Characteres ut in Adelio, sed elytra prothoraci arete applicata, Antemuc 



articulo tertio duobus sequentibus breviore. 

 Type, Seirotrana catemdata, Boisduval (Adelium).

 longiore, ultimo ovato. Prothrrox transversus, lateribus vix rotundatus,
