[254.] v.— HYMENOPTERA. 



[257.] FAMILY SIRICIDjE. 



356. SiREX jrivENCUS Li)iii. — Length of body, raucro included, ii 

 lines ; expansion of wings 20 lines. One specimen taken in Lat. 65°. 



Body black-blue, glossy, punctured very thickly on the head and 

 trunk, in which from each puncture proceeds a black hair. Head between 

 globose and triangular, very hairy with a naked spot behind the eyes ; 

 cheek terminating in a tooth or point as in the other species of the genus ; 

 vertex blue-green ; antennae black, shorter than the thorax ; palpi piceous ; 

 trunk subglobose, with the central part of the thorax and the part between 

 the four anterior legs tinted with green ; legs rufous with the coxse and 

 trochanters black ; wings hyaline with piceous nervures ; abdomen naked, 

 terminated by a subtriangular acuminated mucro or horn ; ovipositor 

 piceous. 



In this specimen the ovipositor is longer and goes further beyond the 

 anal horn than in the European ones, and the horn itself is more dilated 

 at the base. 



[258.] FAMILY FCENIDiE. 



357. FcENU.s JACULATOR Liwi. — -Two Specimens taken in Lat. 65°. 



The American specimens differ from those of Europe, which also 

 vary, in having the red segments of the abdomen marked with a large 

 black basilar dorsal spot, the former having mostly only a darker cloud. 

 Panzer's figure, however, comes very near the American. 



[It is doubtful that the European species occurs in America ; they are 

 probably distinct.]
