AMERICAN HYMENOPTERA. 97 



segment has a whitish band, sometimes broad and entire, but generally 

 more or less interrupted in the middle, and sometimes reduced to a 

 mere dot; the fourth, fifth and sixth segments are immaculate ; the 

 seventh more or less silvery, sometimes whitish. One specimen has 

 the abdomen entirely black, except the silvery tip. Length 3 — 4> 

 lines.

 ware, Illinois, Canada, (Coll. Am. Ent. Soc. and Mr. E. Norton). 



Thirty 9 , fourteen % specimens. The markings of this species are 

 extremely variable, and I can find no constant character by which to 

 separate 5-notafus from higuttatus. Of the 9 » I have before me two 

 specimens with the body entirely immaculate, except a faint, whitish 

 orbital line ; fifteen specimens have a transverse white spot, sometimes 

 very faint, on each side of the third segment — these are the higuttatus 

 of Fabr. — and in one of this last variety, the second segment has a 

 white dot on one side only, and another specimen has a white spot on 

 the sixth segment; 'one specimen has two dots on the second segment, 

 two large ovate spots on the third, and a spot on the sixth, while 

 another has the addition of a very small, faint, whitish line on each 

 side of the fourth segment; and nine specimens have a white spot, va- 

 riable in size, on each side of the second, third and fourth segments, 

 those on the third sometimes confluent, and a spot on the sixth seg- 

 ment — these are the 5-notafus of Say.
