known from North America and it was found that they belonged 

 to what is called in Europe Vespa austriaca Panzer. 



The following description of the species is made on these two 

 American specimens:

'?. Head slightly broader than high. Clypeus comparatively high, 

 scarcely one third broader than high, its anterior margin much projecting, 

 distinctly emarginate, the lateral angles of the emargination strongly pro- 

 duced, almost dentate and slightly directed outwardly. Oculo-malar space 

 very short, the eyes practically reaching the base of the mandibles. 

 Mandibles relatively slender, when compared with other species. Tarsi 

 distinctly heavily built, the joint's are as broad as in other species but 

 much shorter. Horizontal face of first abdominal tergite comparatively 

 long and narrow, about half as long as the second tergite. — Punctura- 

 iion remote and fine on head and thorax; especially on the clypeus there 

 is, in this respect, a marked difference between this and related species. 

 Oh the mandibles also the sculpture is very obsolete. — The whole body is 

 ■covered with erected black hairs, which are very noticeable on the abdo- 

 men. Upper side of all the tibia clothed with very long erect hairs, more 

 abundantly so on the hind legs. 



Coloration. — Black with many pale lemon-yeilow markings : a broad loz- 

 enge on the front between the ant'ennse, the under half of the sinus of 

 the eyes, a large spot in the upper half and a much smaller one near the 

 under end of the temples (behind the eyes), nearly the whole of the 

 mandibles, the clypeus except for its margins and 3 small black spots 

 placed in a triangle on the center. In one specimen, the underside of the 

 antennal scape bears a short and narrow yellow stripe; in the other, the 

 scape is entirely black. — On the thorax, the lateral hind-margins of the 

 pronotum are broadly yellow, as are also two widely separated spots on 

 the scutellum and a smaller one on the upper half of the mesopleurae 

 beneath the insertion of the wings. Tegulse, yellow and brownish. — On 

 the legs, the apices of the femora, the tibiae, with exception of a black 

 stripe on the under side, and the tarsi are yellow, this color, however, 

 turning in certain parts brownish. — First abdominal tergite with a broad 

 apical yellow margin, in front of which are situated, on the transition 

 between the horizontal and vertical portion, two transverse, entirely free, 

 yellow spots. The remaining segments are, for the largest part, yellow; 

 there is a basal black band which is angularly produced in the center, and 

 on each side of this angle a transverse black spot; on the second tergite
