LABENIDEA, new genus. 



Genotype. — Grotea superha Schmiedeknecht. 



This new genus, whUe perhaps more closely allied to Labena 

 Cresson, has many of the characters of Grotea Cresson. The habitus, 

 thorax, and abdomen are more like Labena, while the head, especially 

 the dentate cheeks, the clypeus and antennae, is more like Grotea. 



Generic characters. — ^Head transverse, distinctly narrowed behind 

 the eyes; cheeks produced into a tooth posteriorly; inner margins 

 of eyes distinctly emarginate opposite antennae; labrum exserted; 

 clypeus transverse, the apical part not depressed, truncate, the dorsal 

 suture strongly curved m.edianly; the third antennal joint subequal 

 with the fourth and fifth combined; face finely punctured; scutum 

 long and without notauli; scutellum not margined; propodeum 

 partly areolated, sharply separated from the metanotum by a deep 

 furrow, not separated from the metapleura, spiracle curved, slitlike; 

 prepectal carina terminating well above the middle of the anterior 

 margin of mesepisternum; mesepistemum higher than the cephalo- 

 caudad length; first tergite straight and subequal in length with 

 hind coxae; ovipositor longer than the abdomen, compressed, taper- 

 ing apicaUy on both dorsal and ventral margins, apex with oblique 

 furrows; hind coxae slender, elongate, almost as long as hind femora 

 or first tergite; legs long, tibiae not tv/isted; apical joint of the hind 

 tarsi not especially lengthened and shorter than the two preceding; 

 claws long, bent at almost a right angle apically; onychia very 

 prominent; nervellus reclivous, broken at about the middle.
