and produced ; the posterior angles rounded off ; the base lobate 

 and rounded ; the marginal border wide and reflexed, widest at 

 the posterior angles, continuous on the base ; the median line 

 light, ending behind in an arched transverse line, between the 

 sinuosities on each side of the base, defining the basal part of the 

 prothorax; a short longitudinal impression extending forward 

 from each side of the basal lobe ; the posterior declivous part of 

 the prothorax transversely striolate ; two marginal punctures on 

 each side. Elytra oval (14x10 mm.), convex, marked with seven 

 rows of distinct shallow punctures '^ and two discoidal punctures 

 towards the apex, lightly rounded on the sides, and equally 

 rounded in front and behind ; the humeral angles prominent and 

 upturned, the base emarginate between them, steeply declivous to 

 the peduncle and marked with a double row of umbilicate punctures 

 on each elytron, a row of evenly placed umbilicate punctures 

 along the margins, every alternate one being larger • the lateral 

 margins broad, especially towards the apex. Prosternum lightly 

 excavate between the coxae. The legs strong, the intermediate 

 and posterior tibiae thick and ciliate as in C. odeivahni, only 

 heavier ; the anterior tibiae tridentate externally, the exterior 

 ridge with four projections above the large te^th, the inferior 

 ridge strongly serrate to the apex of the tibiae, the apical plate 

 with a short tooth at the apex.

A very distinct species ; its affinity is to Carenuin (Callis- 

 capterus) odewahni, Casteln., but it differs inter alia in its elytra 

 not being narrowed to the base, and in having only two, instead 

 of three, prothoracic marginal punctures. 



Carenum lepidum, n.sp. 



Smooth, shining ; elytra iridescent with the disc a deep 

 blackish-purple changing to blue or green on the sides, the
