FROM THE NORTH-WEST PROVINCES OF INDIA. 191 
This species most closely resembles V. velutina, and must be arranged next to that 
species. 
2. VESPA FLAVICEPS. (Plate XXI. figs. 10,?, 11, ¥.) 
Female. Length 8 lines. Black, and ornamented with sulphur-yellow spots and bands. 
Head yellow, with a small quadrate black spot that encloses the ocelli; the flagellum 
of the antenne and the teeth of the mandibles black, the scape, and the vertex between 
the summit of the eyes, ferruginous; the eyes extending to the base of the mandibles. 
Thorax—the margins of the prothorax and of the scutellum, a spot on each side of the 
metathorax just above the insertion of the abdomen, and a spot beneath the wings 
yellow; the legs yellow and stained with ferruginous beneath; the cox, and the 
posterior femora at their base, more or less fuscous; the wings flavo-hyaline, the 
nervures ferruginous, the costal nervure fuscous. Abdomen—the first, second, and 
third segments with a yellow band on their apical margins; the bands on the second 
and third segments widen at the sides, where each is slightly emarginate; the two fol- 
lowing segments are yellow, and have an ovate black spot on each side; the apical 
segment yellow beneath; the basal margins of the first, second, and third segments are 
black. 
Worker. Length 6 lines. This sex differs from the female in many particulars. ‘The 
vertex is black; the antenne black, with the scape yellow in front. The thorax, legs, 
and wings as in the female. The abdomen has the apical margins of all the segments 
bordered with narrow yellow bands; the second and following segments have a rounded 
notch on each side. Beneath, the segments with yellow apical margins: that on the 
second segment is broad, and a curved black line runs into it, emanating from the black 
base of the segment; the margins of the three following segments have narrower bands, 
each having a black emargination on each side; very frequently there is a very narrow 
interrupted line of yellow at the base of the abdomen. 
Hab. Binsur, Kumaon, North-west Provinces of India. 
This species has the aspect of one of our British, or one of the North-American 
Wasps; at first sight the workers look somewhat like those of Vespa cuneata. 
3. VESPA sTRUcTOR. (Plate XXI. fig. 12, 3.) 
Worker. Length 5 lines. Head and thorax black; abdomen reddish yellow, with 
black bands. 
Head yellow, the vertex between the eyes black; the scape yellow in front; the eyes 
extending to the base of the mandibles. The margins of the prothorax, a line on each 
side at the base of the scutellum, the tibie, tarsi, and tips of the femora reddish 
yellow; the cox, trochanters, and base of the femora black; wings subhyaline, the 
nervures ferruginous, the costal nervure black. Abdomen reddish yellow, with the 
basal margins of the segments black; the black bands narrow, but widest in the middle,
