No. 2370. BEETLES OF THE TRIBE TILLINI—WOLCOTT. 273 



CYMATODERA SUBSIMILLIS Wolcott. 



Oracle, Arizona, July 11, 1898 (Hubbard and Schwarz). 



This species was based upon the female only. The specimen 

 above mentioned being a male, the opportunity is afforded of giving 

 the abdominal sexual characters of that sex. 



Male. — Fifth ventral segment broadly, rather feebly emarginate; 

 sixth ventral segment small, transverse, broader at base than last 

 dorsal, broadly but distinctly emarginate; last dorsal much longer 

 than last ventral, feebly emarginate at apex. (Plate 43, fig. 7.) 



CYMATODERA MITIS, new species. 



Slender, shining, sparsely pubescent, the intervals with long erect 

 hairs, pale reddish brown, body beneath paler, elytra with a narrow, 

 somewhat irregular ante-median fascia narrowly interrupted at the 

 suture pale yellow. Head very finely and sparsely punctate, more 

 densely on occiput ; eyes moderately prominent ; antennae extending 

 to basal fourth of elytra, joints two, three and four subequal, each 

 distinctly shorter than any of the following joints, joints six to ten 

 moderately serrate, joint eleven one-half longer than the tenth, dis- 

 tinctly compressed. Pro thorax three-fourths longer than wide, dis- 

 tinctly constricted at apical third, strongly compressed at basal fourth, 

 surface minutely and remotely punctate, the punctures slightly coarser 

 and a little closer on the flanks ; ante-scutellar impression very fee- 

 ble. Elytra twice as wide as thorax at base; humeri distinct; sides 

 feebly divergent; apices conjointly rounded; rows of punctures mod- 

 erately coarse, gradually becoming feebly impressed behind the fascia, 

 the punctures separated by about half their own diameter ; intervals 

 near suture wider than the punctures, slightly narrower toward the 

 sides, finely, sparsely and irregularly punctulate. Body beneath 

 sparsely pubescent; metasternum minutely, remotely punctate; ab- 

 domen moderately coarsely, sparsely punctate. Legs sparsely clothed 

 with moderately long pale hairs. Length, 5.75 mm. 



Male. — Unknown. 



Female. — Fifth ventral segment feebly sinuate; sixth short, sub- 

 truncate, much smaller than last dorsal; last dorsal semicircular. 

 (Plate 43, fig. 8.) 



Type locality. — Williams, Arizona. 



Type.— Cat. No. 23121, U.S.N.M. 



Described from one female, collected June 2, 1901, by Schwarz 

 and Barber. 



This species is allied to subsimilis Wolcott, and pallida Schaeffer, 

 from both of which the posteriorly broader elytra, the color and 

 markings, and abdominal sexual characters will readily separate it.
