Tribe OPHIONIDES. 



Tbis tribe consists of large red insects, witb strongly elongate 

 antenna? and legs; tbrougbout Europe tliey are among tbe best 

 known of all Iciixeumonid.e on account of their frequent attraction 

 to light after dark. Their discrimination from the rest of the 

 Ophioxix.i; is rendered extremely simple by the fact that the second 

 recurrent nervure is emitted from the cubitus distinctly before 

 the submarginal, a feature shared only by the Noxotiiachides, 

 in which the antennae are peculiarly short and the intermediate 

 tibiae have but a single calcar. One or two genera of the Axoma- 

 iiuEs have the second recurrent and submarginal continuous 

 through the cubitus, but never with the submarginal postf ureal : 

 moreover their tarsi are broad and the metathorax produced. 



The species of Henicospilus are entirely cosmopolitan in their 

 range, but Opliioa is somewhat more restricted, though very wide- 

 spread. 8chmiedekneciit remarks (Opusc. Ichn.) that he lias taken 

 numerous specimens of both genera in Java, but failed to find any 

 sharp structural or coloratioual distinctions between them and the 

 European forms: he very truly adds that the distinctions are so 

 elusive that unconnected descriptions of single specimens, such as 

 are brought forward by Cameron, in scattered periodicals, only tend 

 to augment the difficulty of monographing the group. 



The Indian species of Ophion appear few in individuals : but a 

 single specimen has, to the best of my knowledge, been taken with
