the yellow ; anal segment with a large yellow spot on each side. Legs ferru- 

 ginous yellow, with the coxse, trochanters and hasal half of the femora, black. 

 Wings hyaline, with the uervures brown. Length 21 mm. 



% . — Similar to the female ; the third abdominal segment broadly and irregu- 

 larly notched in the middle; the fourth, fifth and sixth segments each bearing 

 two lateral black spots ; the rest as in the female. 



Worker. — Similar to the female, though smaller in size. Length 18 mm. 



Hab. — United States ; Carolina ; Amherst, Mass. 



v. sul|>lilii*ea Sauss. ^. — Eyes extending nearly to the base of the man- 

 dibles. Head almost entirely sulphur-yellow, the usual subquadrate frontal spot 

 of yellow rests on the black front and sends a prolongation up to the median 

 ocellus; antennse black, with the scape yellow in front. Thorax black, with the 

 prothorax very broadly bordered with yellow ; an oblique line below the tegulse 

 followed by two spots placed in an oblique line below the hind wing, two longi- 

 tudinal stripes on the mesothorax, two spots narrowed inwardly on the scutellum, 

 a stripe on the front edge of the postscutellum nearly divided medially, two large 

 spots on the back part of the metathorax yellow. Abdomen black, with the same 

 yellow marks as in V. rufa, but so developed as to leave almost no black space ; 

 this color forms in the yellow the following designs: Two points on the anterior 

 face of the first segment and an irregular transverse inark on its superior face, a 

 trilobed spot on the middle of the second, two lateral spots on each of the fol- 

 lowing segments and a longitudinal line on the anal segment; the base of the 

 second segment is also black. Legs all yellow, except the hinder part of the hind 

 and middle coxae, and basal half of the femora. Wings a little smoky, washed 

 with ferruginous ; posterior border of the second submarginal cell twice as long 

 as that of the third. Length 16 mm. 



Hab. — California, Texas, Nevada. 



The markings of this species resemble very much those of T". 

 Carolina, but this is of very much lighter color, being sulphur-yellow, 

 not reddish yellow. The venation of the wings is very different, for 

 V. Carolina has the posterior border of the second submarginal cell 

 equal to that of the third. 



V. cuneata Fab. 9 • — Eyes extending nearly to the base of the mandibles. 

 Head black, with the mandibles, except the teeth, the clypeus, except a vertical 

 stripe, a subquadrate spot on the front, a large mark in the sinus of the eyes 

 prolonged to the clypeus, and a band above and behind the eyes yellow ; antennae 

 black, with the scape yellow in front. Thorax black, with the posterior border 

 of the prothorax, the tegulse, two longitudinal lines on the mesothorax, two spots 

 on the scutellum, a transverse stripe on the postscutellum, two spots on the meta- 

 thorax. a band on the mesopleura and generally two small spots on the meta- 

 pleura yellow. Abdomen black, the first segment with an orange-yellow line on 

 the anterior and posterior borders connected at the sides; the second segment 

 bearing two lines, one in the center interrupted medially and joined at the sides 

 to one on the posterior border slightly tridentate ; the remaining segments with 

 a narrow, apical, yellow border, slightly tridentate. Legs yellow, except a small 

 black mark on the femora of the anterior pair and the posterior side of the
