2 — Process on under side of the sixth abdominal segment not as above, 

 relatively small, sharply pointed or if flattened, the sixth sternite lacks 

 the lateral processes or ridges spinolae. 



2 — Under side of second and sixth abdominal segments with processes, 

 that on second more or less well developed, in exceptional cases lacking, 

 that on sixth simple, median, pointed texana. 



2 — Under side of second and sixth abdominal segments without processes 

 prumosa. 



Females 



I — Neither post-scutellum nor dorsum of median segment (excluding 

 posterolateral angles) marked with yellow 2. 



I — Post-scutellum or dorsum of median segment, or both, marked with 

 yellow pruinosa. 



2 — Last abdominal segment, strongly wrinkled dorsally belfragei. 



2 — Last abdominal segment not wrinkled, punctate 3. 



3 — Bands on dorsal abdominal segments sinuate but not greatly attenu- 

 ated medially, body rather slender spinolae. 



3 — Bands on dorsal abdominal segments wide laterally and much attenu- 

 ated medially or reduced to widely separated lateral spots, body rela- 

 tively robust texana. 



Bembix texana Cresson. 



This species in a general way, may be distinguished by the fasciae being 

 so attenuated and sinuated medially as to enclose more or less well marked 

 black spots on the dorsum of the abdomen. On the second segment of the 

 abdomen this marking is particularly more striking than on the other seg- 

 ments. The markings should not be relied upon too much, however, as 

 specific characteristics, since they are variable. Length 15-18 mm. 



Specimens were collected at Raleigh M. July, 1912, C. L. 

 M; iVI. July and E. August, 1902, F. S.; Overhills, L. Au- 

 gust, 1919, J. E. E.; Princeton, L. July, 1902, F. S. 6 speci- 

 mens: 4 females, 2 males.* 



B. pruinosa Fox. 



This rather large, handsome species may be easily distinguished by the 

 dense pubescence on the head, thorax and base of the abdomen, particu- 

 larh' by the pubescence of the former two. The transverse bands are 

 large and broad. Length 16-19 mm. 



The two specimens, a male and a female were collected at 

 Beaufort, L. June, 1903, F. S.
