ADDITIONAL RESULTS OF COLLECTING INSECTS IN 

 KANSAS AND COLORADO.

^^HE classification of insects in all orders requires a wide diver. 

 ^ sification of study, which, beyond a limited extent, cannot be 

 perfected by any one person, even under the most favorable cir- 

 cumstances. In working upon the specimens of my own collecting) 

 the need of complete knowledge concerning some forms necessarily 

 curtails the systematic treatment of species. 



Under the title of "Some Results of Desultory Collecting of 

 Insects in Kansas and Colorado," a record is given of my former 

 work regarding insects which were personally collected. As men- 

 tioned at the end of this paper, which was published in the Kansas 

 University Science Bulletin, (vol. IV, No. 2), a considerable amount 

 of material remained to be reported upon, my intention being to 

 present the results in future lists. The greater part of the addi- 

 tional material consisted of hymenopterous insects, all the speci- 

 mens having been collected by myself under conditions which have 

 been explained in my former paper already mentioned. As inti- 

 mated, not all of these specimens have been fully studied, but the 

 work of specific determination has advanced to such an extent as 

 to deserve a presentation of the results at this time rather than to 

 subject them to further delay in publication. So far as these re- 

 sults are given, every record for a species contributes toward a 

 better knowledge of geographical distribution and seasonal occur- 

 rence. 



LIST OF HYMENOPTERA. 



The tabulated summary which appears at the end of this list 

 shows the number of species newly recorded for Kansas, and of 

 species taken in both Kansas and Colorado, as well as in each state 

 separately, and also the total number reported, all being arranged 

 with reference to each family as treated. In regard to the species 

 hitherto reported as occurring in Kansas, reference must be given to 

 two papers: One, under the title of " Preliminary List of the Hymen- 

 optera of Kansas," was published by Prof. F. H. Snow in Transac- 

 tions of the Kansas Academy of Science, volume VII, pp. 97-101; 

 aud the other, entitled "A List of Kansas Hymenoptera," by J. C. 

 Bridwell, appeared in volume XVI, pp. 203-211, of the Transac- 

 tions. The names of those species which I report as being new to
