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, S? .) 



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 antennae 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; this legs yellow and stained with ferruginous beneath; the coxse, 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 antennae 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 foUowing segments have narrower bands, 

 each having a black emargination on each side ; very frequently there is a very narrow 

 interrupted line of yeUow 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 XXL fig. 12, $.) 



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 tibiae, tarsi, and tips of the femora reddish 

 yeUow; 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,
