Female. Length 4-5 lines. — Black; the anterior margin of the 

 clypens, the labrum, mandibles, and antennae ferruginous; the 

 inner orbits of the eyes, as high as the insertion of the antennae, 

 yellow. Thorax — the collar, tubercles, tegulae, two spots on the 

 scutellum, one on the postscutellum, and a dot on each side of the 

 metathorax yellow; the legs ferruginous ; the coxae, trochanters, and 

 femora beneath at their base black, the posterior pair also more or 

 less black within ; the wings fulvo-hyaline, their nervures pale fer- 

 ruginous. Abdomen — each segment having a yellow fascia, the 

 first usually interrupted, the two following attenuated in the 

 middle. B.M. 



Male. — Yery closely resembling the female, but having the clypeus 

 anteriorly, the sides of the face, the scape in front, the labrum, and 

 mandibles yellow ; the latter ferruginous at their tips ; the scape 

 black above, and the four or five basal joints of the flagellum black 

 above ; the head and thorax have a thin hoary pubescence ; the 

 anterior coxae and the tibiae in front, and a spot on each side of the 

 breast in front, yellow ; an interrupted line on the collar, the tegulae, 

 and two spots on the scutellum yellow ; wings subhyaline, the 

 nervures pale ferruginous, the apical margins faintly clouded as in 

 the other sex ; the abdomen as in the female. B.M. 



This species is abundant in all parts of the country, and appears in 

 April. It is not subject to vary greatly, but the females sometimes 

 have an uninterrupted yellow band on the basal segment of the abdo- 

 men, and the two minute yellow spots on the metathorax are occa- 

 sionally obsolete. An entire fascia on the basal segment of the 

 abdomen is sometimes found in the males.
