almost wholly yellow, at least without distinct separation of 

 two oblique bands. This form resembles very closely P. minor 

 Beauv., collected by me in northern Texas, and raises a ques- 

 tion whether exclamans is not indeed a'highly colored variety 

 of minor.

 catskillensis Sauss. Kansas, Lawrence; May; July. New to 

 Kansas Hst. The specimen collected in the latter month 

 has the yellow border of first abdominal segment some- 

 what enlarged on the sides. Colorado, Denver; August. 

 Variety a. Colorado, Colorado Springs and Denver; Au- 

 gust. Two specimens show mutations as follows: One 

 with oblique yellow line connecting with the border on 

 sides of the second abdominal segment; the other with 

 small disconnected spots instead of the oblique yellow 

 line. 

 In studying the variations of color markings in this species, 

 variety d was identified from material collected by my- 

 self in Venango county, Pennsylvania. 

 All of the above examples are females, 

 fulvipes Sauss. Kansas, Lawrence; August. New to the 



Kansas list, 

 tenuatus, n. sp. Colorado, Denver; August, 1906. Type; 

 one female specimen. 

 Collected with catskillensis Sauss. and other varieties, to 

 which it bears a very close resemblance, but the elon- 

 gated thorax of this specimen presents a structural 

 difference of sufficient importance to entitle the insect 

 to recognition as a distinct species. 

 Thorax a little more than twice as long as the greatest 

 width between base of wings; body feebly shining, 

 black with yellow markings, pubescence extremely 

 scanty, fulvous on dorsum of thorax, fuscous on front 

 of head above antennal insertions, otherwise cinerous
