No. 2370. BEETLES OF THE TRIBE TILLINl—WOLCOTT. 271 



Type.— Cat. No. 23119, U.S.N.M. 



Described from one female reared in May, 1897, by H. G. Hubbard. 



Similar in form to elegans Erichson, to which it is nearest related. 

 The form is, however, a little more elongate, the prothorax propor- 

 tionately longer and more strongly compressed at base, the punctua- 

 tion throughout more sparse and fine, the median elytral fascia is but 

 very slightly oblique, and finally the color is quite different. 



The 15 specimens of elegans that I have examined have, without 

 exception, the prothorax quite coarsely and densely punctate and 

 show no tendency to vary in the direction of the species above de- 

 scribed.

CYMATODERA AEGRA, new species. 



Moderately robust, feebly shining, moderately clothed with long 

 recumbent and erect pale yellowish hairs, reddish brown, occiput of 

 head with large black maculation, elytra piceous behind the base with 

 a narrow angulate median fascia pale yellow. Head very sparsely, 

 moderately finely punctuate; eyes prominent; antennae reaching to 

 about basal fourth of elytra, joints two, three and four short, subequal, 

 each shorter than any of the following joints, outer joints gradually in- 

 crassate apically, not at all triangular. Prothorax twice as long as wide 

 at base, very feebly constricted at apical third, moderately com- 

 pressed at basal third; surface finely, sparsely punctuate; ante- 

 scutellar impression very feeble, scarcely discern able. Elytra twice 

 as wide as thorax at base; humeri distinct, sides parallel to apical 

 fourth; apices conjointly rounded; rows of punctures coarse, deep, 

 extending nearly to apex toward which the punctures are but slightly 

 smaller and feebly impressed, the punctures separated by at least 

 their own diameter; intervals narrower than the punctures, finely, 

 sparsely, irregularly punctate. Body beneath sparsely pubescent; 

 metasternum rather finely, remotely, feebly punctate, the abdomen 

 a little more densely. Legs more densely pubescent than the venter. 

 Length, 4-5.5 mm.
