RHIMPHOCTOS'A. 467 



as broad ; areolet entire and sometimes sessile, emitting the 

 recurrent nervure but very slightly before its apex; nervellus 

 distinctly geniculate below its centre and sometimes emitting a 

 distinct nervure. 



Range. Europe, Assam. 



This genus was erected with no type ; but recently Professor 

 Schmiedeknecht, following Tschek, has referred Pyracmonfulvipes, 

 Holing. (Sv. Ak. Handl. 1858, p. 102) to it. An Indian pair, 

 differing only in the absence of the clypeal production and in the 

 shape of the areolet, appears also to belong to it.

 dull rufescent beneath. Thorax with 

 the mesonotum abruptly sloping 

 apically; metathorax gradually de- 

 clivous throughout and apically a 

 little produced between the hind 

 coxae; discally bicarinate throughout, 

 with the petiolar area as long as, 

 though broader than, the parallel- 

 sided areola, which is thrice as long 

 as broad, discrete from the minute 

 basal area and emitting costulae from 

 its basal third ; lateral cariuae strong 

 and remote. Scutellum subconvex

 from just beyond its centre to its apex ; second deplanate and 

 scabrous; third strongly compressed and hardly smoother; the 

 following also compressed and subnitidulous ; valvulse exserted ; 

 terebra slightly reflexed and as long as the basal segment. Legs 

 slender and black, with all the calcaria, the anterior tibiae and tarsi, 

 and the front femora internally, testaceous ; claws pectinate. 

 Wings not narrow, hyaline, with the tegulsa and stigma black, and 

 the radix testaceous ; areolet not large, distinctly petiolate and 

 emitting the recurrent nervure hardly before its apex; second dis-
