272 NATURAL HISTORY BULLETIN. 



A. MORUI.US Lec. Canon City, Wickham; Colorado Springs; Alamosa; 

 Garland; Buena Vista; Pike's Peak, 7,000 to 8,000 feet; Dome Rock; 

 Red Mountain Road, 9,000 to 10,000 feet. 



A. NIGRIPES Horn. Colorado, Horn. 



A. ONCTUS Lec. Colorado, Horn. A specimen in the Agricultural College 

 collection marked "cinclus det. Riley " differs from the description in 

 not having a yellow abdomen and in the elytra being broadly mar- 

 gined with yellow. 



Trichochrous sparsuS Casey. Colorado, Casey. 



T. ANTENNATUS Mots. This name occurs in the Packard list as from 

 Golden. I have also seen a number from Montrose with this label but 

 it is doubtful where they would go by Major Casey's revision. His 

 understanding of Motschulsky's species is different from that of Dr. 

 Leconte. 



T. iiNLEQUAUS Casey. Colorado, Casey. 



T. Funebris Casey. Colorado, Casey. 



T. TEXANUS Lec. Southern Colorado, Leconte. 



T. ^ENESCENS Lec. Upper San Juan, Bowditch. 



CradyTES SERRICOLUS Lec. Trinidad and Rocky Ford, Gillette; taken in 

 September. 



C. SERRUEATUS Lec. San Luis Valley, Bowditch. 



LiSTRUS INTERRUPTUS Lec. Fort Collins; Steamboat Springs. 



L. SENIUS Lec. Southern Colorado, Leconte; Durango; Cochetopa Pass; 

 Florissant; Canon City; Colorado Springs; West Cliff; Eastern Custer 

 County, Cockerell; Buena Vista; Estes Park Toll Road; Fort Collins; 

 Steamboat Springs. Common and widely distributed over the state. 



L. EUTEIPES Lec. Vicinity of Fort Collins; Dolores. 



L. RUBRiPES Casey. Colorado, Casey. 



Dasyteelus nigricornis Bland. Southern Colorado, Leconte; this or an 

 allied species occurs at Dolores and Ouray.

 Gulch, Custer County, Cockerell; Garland; Veta Pass; Leadville, not 

 uncommon on the foliage of dwarf pines; Breckenridge; Mountains south- 

 west of Montrose; Upper San Juan; Little Willow Creek. 



D. obttjsus Casey. Colorado, Casey. 



D. breviusculus Mots. The name occurs in the Putnam list. This is not 

 the species to which Casey applies Motschulsky's name, as he does not 

 follow Leconte in his identification. 



Dasytastes ruficoeeis Ulke. Colorado, Bowditch. 



EschaTocrepis consTrictus Lec. Montrose, Bowditch. 



PSEUDALEONYX petjmbeus Lec. Beaver Brook; South Fork of San Miguel.
