VESPID^. 



PoLiSTES FuscATUS Fabr. Ten specimens. Tepic. 



PoLisTES CARNIFEX Fabr. Ten specimens. Tepic. 

 All very large. 



PoLiSTES BELLicosus Crcss. Ten specimens of a form

 Texan individuals by the scutellum and metanotum 

 (postscutellum) being entirely yellow, and the markings 

 in general, particularly those of the abdomen, more ex-

 lines which occur in the Texan form. The specimens 

 are from San Jose del Cabo. 



PoLisTES MINOR Pal. Bve. San Jose del Cabo. Three 

 specimens. 



PoLiSTES LiNEATUS Fabr. Numerous specimens. San 

 Jose del Cabo. 



POLYBIA DECEPTA n. Sp.

 the mandibles, which are ferruginous, and the antennae,

 basal two-thirds or more of anteriors black, as are also 

 the nervures, on the remainder whitish, the nervures 

 yellowish, posteriors blackish throughout; middle-segment 

 with a deep, convex, depression, extending from base to 

 apex; hind coxee very large; medial and hind tarsi with 

 joints 3 and 4 greatly extended at apex within, particularly 

 the fourth joint: petiole of abdomen robust, most convex 

 in middle above, before the apex with a transverse im- 

 pression. Length, 15 mm. 



One specimen, either a ? or ^ . Easily distinguished 

 by the color of wings, which is exactly as in Chartergus 

 a-picalis, as in the rest of the insect. It evidently belongs
