3IO NATURAL HISTORY BULLETIN. 



D. similis Lec. Garland; Leavenworth Valley. 



D. piceaperda Hopk. Boulder, Hopkins, in bark of Engelmann's spruce; 

 Leadville; Silver Plume; Argentine Road. The specimens were all 

 named by Prof. Hopkins and belong to a new variety or subspecies 

 which will be characterized by him in due time. There is little doubt 

 that some of the older records for Colorado Dendroctoni belong really 

 to this species, which has been confounded with D. rufipennis. 



D. simplex Lec. Colorado, Dietz. 



D. approximate Dietz. Colorado, Dietz. 



Hylastes macer Lec. Colorado, Snow. 



H. longus Lec. Leadville; West Cliff; Garland; Veta Pass. 



H. porosus Lec. Boulder, Hopkins, in bark of pine; Rico, in doubt. 



H. gracilis Lec. Colorado, Putnam. 



Hylurgops rugipennis Mann. Veta Pass, 9,400 feet; Leadville. 



ANTHRIBID^E. 



GonoTropis gibbosus Lec. West Cliff. 



Eurymycter fasciatus Oliv. Northern Colorado, May, Gillette. 

 Aelandrus bifasciaTUS Lec. Garland; Ouray; Horsefly Peak; Rico. 

 Brachytarsus alternates Say. La Veta; Colorado Springs. 



B. griseus Lec. South Park, Snow, common on Actinella richardsonii; 



Buena Vista. 



ADDENDA. 



After the first part of this catalogue had been printed, a " Revision of the 

 Cicindelidse of Boreal America" by Mr. Chas. W. Leng, appeared in the 

 Transactions of the American Entomological Society. The following 

 records should be added to those which I have already given for that 



family. 



Cicindeea oslari Leng. Bronze specimens from King Solomon's Peak, 

 Needle Mountains, San Juan Range, 9,500 feet, July and August; green 

 specimens from southwest slope of Mount Wilson, San Miguel Range, 

 12,000 feet, July. Both lots were collected by E. J. Oslar. This form 

 will rank as a not very pronounced race or variety of C. longilabris. 



C. bowditchi Leng. Vicinity of Durango, July and August, Bowditch. 

 C. UXICOLOR Dej. Colorado. 



C. obuquaTa Dej. Mr. Leng revives this name for the broadly marked 

 forms of C. vulgaris; I have a specimen from Buena Vista.
