Specimens from the New Mexico colony are close to u-scripta, but 
again they do not agree perfectly and there is much variation to be 
considered. When specimens from other localities are considered also, 
it becomes obvious that the extent of maculation varies in a complete 
spectrum all the way from “arcuate.” to “u-scripta” . I have tabulated 
the variation in two color characters (Tables I and II), selecting 
these two merely because Parker emphasized them. I have also studied 
other characters, such as the very noticeable variation in the develop- 
ment of the U-shaped markings on the mesoscutum, with very similar 
results. This species has not been collected in enough localities to en- 
able one to be certain of the relation of geography to color pattern, 
but the available evidence suggests a northwest to southeast cline.

1 Paratypes of u-scripta, bearing no further locality data. These specimens 
otherwise have the yellow maculations generally reduced as compared to 
Arizona specimens, and also have a large black spot on the clypeus.

Observations on Colony at Port Isabel, Texas 
This colony was first discovered June 23-25, 1956, but at this time 
it was evident that the wasps had nearly completed their activities for
