4 COLEOPTERA CHLAMYDAE. 



and the apical region shows a good many broken and one 

 fairly marked sutural ridge. The elytra are somewhat com- 

 pressed laterally behind the shoulders, pygidium coarsely 

 rugosely punctate with a faint median line, pectus and 

 thighs with a dark spot. 



Diaspis apicicollis nov. sp. Bronzed, thorax greenish ; elytra 

 coppery brassy, becoming dark behind ; labrum and antennae dark 

 fulvous : thorax elevated behind into a high peak which is bent back- 

 ward at its apex ; sulcus well marked behind and at apex of hump, 

 becoming obsolete in front ; metascutellum very plain ; elytra narrow 

 behind with a very strong oblique ridge from the humerus almost to 

 the suture, which is dentate ; prosternum broad, very moderately 

 compressed and obtuse behind ; length 3.5 mm. 



Type. — One d^ ; Toledo District, Br. Honduras (Peck). 



Head finely punctate, with a fine line on the vertex, thorax 

 rather smooth and dull, with scattered fine punctures which 

 gradually become thick and large, going up the sides of the 

 hump, which is well limited at the sides and behind by a 

 smooth basal sulcus, which is continued towards the front 

 by a shallow depression vaguely colored greenish. The 

 hump has the appearance of being pulled back, with the apex 

 bent back so that it is on a line with the rear edge of the 

 thorax. Elytra are sparsely punctate, more closely behind, 

 the oblique ridge running very strongly to about the middle 

 of the suture ; it is joined, or nearly so, by two lines from 

 the base, one sutural, the other basal median. Between 

 these two short lines is formed a deep pit which shows 

 brassy bronze, including the scutellar region ; the oblique 

 ridge forms the forward edge of an oblique constriction ; 

 the usual elevated lines show faintly at the rear as two or 

 three costiform tubercles and the punctures become obso- 

 letely reticulated ; pygdium punctate, uneven, with a faint 

 median line. 



As a matter of convenience I prefer to retain the old name 

 Diaspis aside from Mr. Schaefifer's paper in the Brooklyn 

 Bulletin. 



The noticeable features are the thoracic hump, the oblique 

 ridge and the coloration.
