FIG. I. I. 

 VESPA DECIM-MACULATA. 



TEN SPOTTED WASR 

 HYMENOPTERA. 



GENERIC CHARACTER. 



Mouth horny, with a compreffed jaw : feelers four, unequal, and 

 filiform : antennae filiform, the firft joint longeft and cylindrical ; eyes 

 lunar : body glabrous : fting pungent, and concealed within the ab- 

 domen. Both fexes have the upper wings folded. 



SPECIFIC CHARACTER. 



Vespa decim-maculata. Black : thorax immaculate: fcutel 

 bidentated : firft five fegments of the abdomen, with a fub- 

 marsinal white dot on each fide. 



Nearly allied to the Linnaean Vefpa wiiglumis in point of fize, and 

 general appearance, but differing in one very effential particular : the 

 number of white fpots on the abdomen. The Vefpa uniglumis, (Crabro 

 uniolumis of Fabricius) has white marginal dots only on three fegments 

 of the abdomen ; while, in our fpecies, the firft five fegments have a 

 very confpicuous white dot on each fide. There are three or four 

 other fpecies of Linnaean Vefpa, defcribed by Fabricius, in his new 

 genera Crabro and Philanthus, that feem to bear fome refemblance to 

 this infect, but which, on companion, appear to be certainly diftinft.
