subsutural white spot at the basal fourth, shading into pale brown exteriorly ; 

 contiguous to this pale spot, their anterior portions forming a part of it, their 

 posterior portions blackish brown, is on each elytron a series of three short lines 

 or tufts of erect or suberect scales occupying alternate intervals. Behind the 

 middle is a similar transverse series of four prominences, two on each elytron, 

 occupying the second and fifth interspaces in similar in coloration to those of 

 the anterior series. There is a conspicuous white spot at the side margin oppo- 

 site the first ventral segment, and the scales bordering the apical truncature are 

 pale brown. Scales beneath in great part white, feebly intermixed with pale 

 brown or lavender posteriorly. Eyes most closely approximate or at slightly 

 above the middle, where they are separated by a distance varying from one- 

 fourth to one-sixth of their own width. Prothorax parallel behind the rather 

 strongly marked apical tuhulation ; apical truncature unusually wide. Ijcngth 

 2.3-3 mm., and from slightly less to slightly greater than 2i times the width. 



Arizona; Catalina Mountains (Schwarz). 



I have used the MS. name given the species by its discoverer. 



C filicornis n. sp. — Form robust, suboval, prothorax rather strongly con- 

 stricted apically, sides behind the constriction subparalled and broadly arcuate. 

 Eyes separated at the middle by about one-sixth the ocular width. Antennse 

 slender, the club very narrow and extremely gradually formed ; second joint of 

 funicle a little longer than the first and equal to the third and fourth united. 

 Beak slender, highly polished and subimpunctate beyond the insertion of the an- 

 tennae. Scales of the upper surface largely white and pale brown, confusedly 

 intermingled. Prothorax with large white spot at sides posteriorly. Elytra each 

 with a white spot at the humeral angle, a transverse spot at the basal third occu. 

 pying interspaces 2-5, white internally, becoming pale brown externally ; a 

 shorter transverse spot near apical third, occupying the third and fourth inter- 

 spaces, and a larger spot at the side margin opposite the second ventral segment 

 extending inward to the seventh interspace. At the middle of the elytra there 

 is a black spot on interspaces 2 and 3, and posterior to this a white stripe on the 

 second interspaces. The transverse rows of prominences described in the preced- 

 ing species are present though less marked, the posterior row being subobsolete. 

 Scales beneath white almost throughout. Length 4 mm., width very nearly 2 mm. 



Texas (San Diego). Collected by Mr. Schwarz. 



Described from a single specimen in the National Museum collec- 

 tion. In this species the markings are of the same type as mjatro- 

 phae and mammillatus. The eyes are more approximate than in 

 any other species of the present group and the antennal club is nar- 

 rower than in any other species of the genus represented in our 

 fauna ; in both respects, however, it is approached by j atropine ■

Robust, suboval, form and markings nearly as in filicornis. The 

 latter are described as follows by LeConte :
