264 Memoirs on the Coleoptera 



The pale elytral vittae much wider, about as wide as the external black 

 vitta, the elytra much less elongate, relatively broader; head finely 

 but strongly, less sparsely punctulate, the impressions between the 

 eyes less definite; eyes a little larger, not quite so prominent; an- 

 tennae rather thicker, half as long as the body, shining black, the 

 three basal joints more or less testaceous; prothorax a little more 

 than one-half wider than long, widest more evidently before the 

 middle, the sides subevenly rounded, finely but sharply reflexed to 

 the basal angles, which are sharp and minutely subprominent at tip, 

 the basal part thence to the basal lobe much more transverse than 

 in the preceding, the surface forming the lobe more depressed and 

 punctate, the sulcus not well defined; general surface features and 

 fine median stria as in the preceding; elytra a fourth longer than 

 wide, slightly inflated behind, much more than twice as wide as the 

 prothorax, the pale vittae much broader, equal in width to the 

 black vittae, the submedial pale vitta deflexed internally at its 

 posterior end to the first stria, the very fine feeble striae and minute 

 interstitial punctures nearly as in the other species; legs black, the 

 femora pale basally, the tibiae pale rufo-flavate, black at tip. Length 

 5.75 mm.; width 2.5 mm. Colorado (Boulder Co.). 



devincta n. sp. 



The species usually called hivittata Fabr., I have entered above in 

 the name given it by Dejean; guadrivittata is at least accurately 

 defined by the author and is therefore definite, but this cannot 

 be said of the Fabrician species, whatever it may prove to be. 



Coptodera Dej. 



The salient external features of this genus are the stout and 

 rather convex body, very large head, short transverse prothorax, 

 elongate labrum, comparatively short antennae, complete absence 

 of the basal thoracic lobe of Lebia, indentation of the sixth elytral 

 stria from the middle to apical sixth and the unusual position of the 

 two dorsal punctures, the anterior being very near the base, ad- 

 joining the third stria, and the posterior only slightly behind the 

 middle and at the second stria. 



The considerable series in my collection from Indiana, Maryland 

 and North Carolina agrees perfectly with LeConte's description 

 of his viridipennis from Alabama, and, if really identical with cerata 

 Dej., the latter name must be regarded as unhappily chosen; this 

 however was due primarily to Knoch, who sent it to Dejean under 

 the manuscript name Lebia cerata; the green color of the elytra is 

 intense and vivid and the head and pronotum are deep greenish- 

 black.
