AMERICAN COLEOPTERA. 173 



1. T. crista! si Casey.— Very robust, piceous, feebly shining, vestiture not 

 very dense, revealing in great part the surface of the elytra, and the middle 

 third of the pronotnm posteriorly. Antennal club subequal in length to all 

 the remainder, joints 3-7 about as wide as long. Prothorax about one-half 

 wider than long, sides arcuately converging to base, the hind angles rounded, 

 disk strongly gibbous, surface granulate, vestiture dense, except as above noted, 

 intermixed throughout with longer fine erect hairs, the sides broadly clothed 

 with whitish matted web-like pubescence; summit of the gibbosity with two ap- 

 proximate tufts of dark brown and fulvous hair, and anterior to these two simi- 

 lar tufts which are slightly less approximate. Elytra one-third wider than the 

 prothorax, sides parallel, humeri narrowly rounded and broadly exposed. Sur- 

 face with coarse punctures irregularly placed, and numerous lines and patches 

 of small rounded granules; vestiture confusedly variegated with white, brown 

 and black, the humeri, an oblique subsutural median spot, and a subapical spot 

 of denser white hairs. There are two series of four blackish brown tufts of short 

 erect hairs, one beginning at the umbone, extending obliquely backward and 

 then forward to the suture; the other at the apical third, transverse and ante- 

 riorly arcuate. Lower surface simply pubescent and rather closely granulate, 

 except the ventral segments, which are simply punctate, except along the outer 

 margins. Legs rather densely pubescent, the femora and tibia} with numerous 

 long erect hairs. Length 5.2-6.8 mm. 



Pacific Coast from Los Angeles County, California to Oregon. 

 This species seems to have been most frequently taken in the Coast 

 Range of "Middle California, the majority of specimens examined 

 coming from the Santa Cruz Mountains; it is distinctly more robust 

 than any other species of our fauna and is the only one occurring in 

 the region which it occupies. 



2. T. klagesi n. sp. — Form and size of gibbosa ; vestiture more yellowish 

 gray and less dense, especially on the elytral disk where it is obscurely vittate 

 in arrangement. The basal dark area of the elytra is less conspicuous, the pos- 

 terior series of blackish tufts slightly less apical in position, and both the elytral 

 and thoracic tufts without admixture of fulvous hairs. The intermediate anten- 

 nal joints seem slightly less elongate, being scarcely longer than wide. Length 

 5.8-6. i mm. 



Hab. — District of Columbia; Pennsylvania (Mauayunk ; " Bucks 

 County," Jeannette) ; Virginia (Penington Gap) ; Kentucky. 



This species has a somewhat limited range, but is apparently not 

 rare. Most eastern collections that I have examined contain one or 

 more examples almost invariably mixed with gibbosa. The speci- 

 mens in the National Museum collection were labeled " n. sp." by 

 Mr. Schwarz, and Mr. Henry Klages of Jeannette, Pennsylvania, 

 has also recognized its specific distinctness in a note in his "Addi- 

 tions to Hamilton's List of the Coleoptera of Southwestern Penn-
