Fam. CHRYSIDID^. 



Chrysis new sp. 



This beautifal little green-blue species occurred iu small numbers at 

 Colorado Springs, August 13. 



Fam. ICHNEUMONID.E. 



Agathis vulgaris Cresson. 



Common in the vicinity of Colorado Springs, and chiefly in places 

 near water, where the plants grew dense and tall, August 13 and later. 



Microdus new sp. 



Occurring singly among the tall weeds in the vicinity of CaQon City, 

 August 11. 

 OpMon purgatum Say. 



Eare in the western suburbs of Denver, August 8. 

 Campoplex laticinctus Cresson. 



Taken singly beyond Colorado Springs, near the Fountain Creek, 

 August 16. 

 Kototrachys reticulata Cresson. 



Two specimens from Colorado Springs, August 13. 

 JVototrachys new sp. 



Taken at CaSon City, August 11. Only two specimens seeu. 

 Cryptus americanus Cresson. 



Seen in many places on the highlands west of Denver, and also at 

 Bijou, August 18 and 19. 

 Cryptus tejonensis Cresson. 



Two or three specimens seen flying in Clear Creek Caiioil, but only 

 one captured, August 6. 



From the above list of names, with the localities of the species, it 

 will be readily seen that a most interesting contribution to the history 

 of modern high types of insect life might be made by a careful and full 

 survey of the territory of Colorado east of the mountains. Every large 

 area yields forms peculiar to itself, and, when these shall have been all 

 brought together, it will be possible to entertain a more adequate idea 

 of the limits of each. We may fairly expect to find separate fauna 1 

 districts north and south of the Divide. 



NEUROPTERA. 



Fam. HEMEROBi:S^A. 



Hemerohius sp. 



Two or three species of this genus were swept from bashes iu the 

 Clear Creek Canon and in the CaSon of the Arltansas. 

 Folystcecliotes punctatus Fab.
