Belongs to the C. smaragdulum group; by its head with two 

 supraorbital punctures it shows an affinity to C. odewahni Cast., 

 and C. distinctum Macl., but it is at once difterentiated from 

 these species by the prothorax with only two lateral setse, in this 

 resembling C. frougatti^ SI., to which, however, it has no close 

 affinity, differing by its very widely securiform apical joint of the 

 labial palpi, prothorax with marginal channel and border not 

 wide, &c. 



Carenum morosum, n.sp. 



Elongate-oval, convex, l?evigate; head with one supraorbital 

 seta on each side; prothorax transverse, lateral margins without 

 setigerous punctures, base sinuately subtruncate without median 

 lobe; elytra cordate, impunctate on disc and on basal declivity; 

 anterior tibiae 2-dentate, intermediate tibi?e stout, incrassate, with 

 a well marked spiniform spur at outer apica langle. Black. 



Head large, convex (6 mm. across eyes); frontal sulci deep, 

 subparallel, reaching back as far as base of eyes; eyes rather 

 prominent, strongly inclosed in orbits at base. Prothorax 

 transverse (5x7 mm.), convex; sides lightly rounded, subparallel 

 in middle, very lightly narrowed to anterior angles, these 

 prominent, obtuse, more strongly narrowed to posterior angles, 

 these rounded but marked; border strongly reflexed, narrow on 

 middle of sides, much wider near anterior angles, widelyexplanate 

 at posterior angles, widely subsinu ate on each side of base behind 

 posterior angles, narrowed and emarginate on middle of base; 

 median line deeply impressed; a well marked foveiform impression 

 on each side of base about half-way between posterior and median 

 line. Elytra hardly wider than prothorax (9-6 x 7*2 mm.); base 

 widely emarginate, truncate; sides gently narrowed to apex; 

 border reflexed, strongly so towards base, upturned at humeral 

 angles; lateral channel wide behind humeral angles; lateral 

 ocellate punctures widely placed (about twelve on each side). 



* In the original description of C. froggatti the anterior tibise are twice 

 mentioned, the first time erroneously as bidentate; they are trideutate.—
