having the eyes " very small, separated from the base of the 

 mandibles by more than two thirds of their own length," 

 they being here separated by one third only or by the length 

 of the three mandibular teeth ; in schach there are only two 

 teeth, and it bears no black markings. Saussure (' Vespides,' 

 i. p. 104) says that the mandibles of the male are " tres fortes, 

 longues et arquees, .... leur base tres epaisse, amide d'une 

 forte dent dirigde en dedans," which is certainly not the case 

 in our species, in which they are broad at the base, slightly 

 obliquely narrowed towards the apex. The clypeus is quite 

 flat, not convex ; the sides at the top are broadly rounded ; 

 the centre is transverse ; the occiput is sharply margined. 



Polistes gallicus, Fabr. 



This common European species may be added to the 

 Indian fauna. I have seen an example from Grilgit. It- 

 belongs to the European form, not to the Eastern Asian var.

Polistes rufolineatuSj sp. n. 



Ferrugineus ; vertice, meso- metathoraceque nigris, lineis 2 mesonoti, 

 scutello postscutelloque rufis ; pedibus rufis, coxis, trochanter-

Head ferruginous ; the ocellar region from shortly behind 

 the posterior pair, from eye to eye, and extending along the 

 upper part of the eye-incision, black ; the front and vertex 

 punctured, but not very strongly or closely ; the antennal keel 

 stout, roundly dilated behind and carinate in the middle. 

 Clypeus broader than long, roundly convex, the top trans- 

 verse, the angles oblique; the apex with the sides oblique; 

 the punctures are sparse and moderately large. Mandibles 

 rufous, sparsely punctured ; the teeth black, the middle one 

 smaller than the others. Antennas rufous ; the five basal 

 joints of the flagellum black above. Thorax black j the pro- 

 thorax, two lines on the centre of the mesonotum, a much 

 shorter one opposite the tegulse, a mark, narrowed below, 

 under the tubercles, the scutellum and postscutellum, rufous. 

 Mesonotum almost impunctale ; the scutellum with shallow 

 scattered punctures. Metanotum, except at the base, irregu- 

 larly and rather widely transversely striated. Pleural bearing- 

 shallow punctures ; the apical half of the metapleurae obliquely
