This genus differs from 8yndipnu$, of which it A\as considered 

 to form a section by Thomson (loc. cit.), in the possession of a 

 distinct areolet, etc. So little has been known of tlie single 

 Paloearctic representative of this genus, Iclineumon scotopterv.s^ 

 Grav. (Mem. Ac. Sc. Torino, 1S20, p. 377), that Marshall left it 

 in 1872, as placed by Stephens in 1835, in the genus Tryplwn,. 

 and in 1880 Bridgman redescribed it (Eutom. xiii, p. 54)' under 

 the name Perilissus fiimatus. Two American species are also 

 known. The testaceous body and dark wings of the Oriental 

 species render it a very conspicuous insect.
