ACJEXITIDES. 39 



basally black; liind legs darker fulvous, with coxae and tarsi 

 yellower ; hind coxae broadly black internally at the base and 

 externally at the apex, their trochanters broadly black above 

 and the femora black above at the base. Wings clear hyaline ; 

 stigma infuscate, nervures darker, and tegulae flavous. 



Length 11-12 millim. 



ASSAM : Khasi Hills (Rothney). 



Type in the Oxford Museum, labelled brunneicornis by its

Tribe ACJENITIDE8. 



This tribe consists of several aberrant genera, of which Accenitus 

 and Collyria appear sufficiently closely related. Of the rest, 

 Coleocentrus is intermediate between the PIMPLINJS and the 

 Ophiouid genus Anomalon; (Edemutopsis might with more pro- 

 priety be placed in the TBYPHONIXJE, near Tliymaris; and the 

 exclusively Indian Tanera was thought by its author to appertain 

 to the LISSOXOTIDES. If relegated to the PIMPLIXJE, which would 

 seem their most natural position in our artificial classification, all 

 fall into the present tribe on account of their elongate hypo- 

 pygium, which entirely conceals the base of the terebra, and in 

 many cases extends to or even beyond the abdominal apex. The 

 first three genera are stout insects, with elongate and incrassate 

 hind legs, and short, subclaviforru antenna?; the last two are 

 much more slender, with elongate and filiform antennae, which 

 often exceed the body in length, and with the legs normal and 

 slender. As already remarked, it is exceedingly probable that 

 the distinction between this group and the last is less than has 

 hitherto been supposed ; and some of Cameron's species included 

 therein should, quite possibly, be placed in the present tribe, 

 since he himself was uncertain concerning their position. No 

 hosts of the Indian species have yet been noted.
