LABENIDEA SUPERBA (Schmiedeknecht). 



Grotea superba Schmiedeknecht, Gen. Insect., fasc. 62, 1907, p. 95, pi. 1, fig. 8. 



This is very probable the same as Pimpla gayi Spinola.

It seems probable that Atractodes lineata Brulle also belongs to 



this genus. 



Genus GROTEA Cresson. 



Grotea Gresaon, Proc. Ent. Soc. Phila., vol. 3, 1864, p. 397. Genotype. — Grotea 

 anguina Cresson. (Monobasic.) 



Cameron ^ when he placed both Nonnus and Grotea in the Ophioni- 

 nae without giving any reasons, is the only author who considered 

 that this genus was not allied to Lahena Cresson. Krieger ^ transfers 

 Atractodes lineatus Brull6 to Grotea, but since it is evident that Brulle 

 did not correctly understand the genus Atractodes we can not justly 

 consider that he would place Grotea in the group to which this genus 

 belongs. 



Although the genus Grotea is very distinct, and when once known 

 easily recognized, there can be but little doubt that it is allied to 

 Lahena. This relationship is made more certain by the genus Lahe- 

 nidea, which is more or less intermediate between the two. 



Generic characters. — Head subtransverse, distinctly naiTowed 

 behind the eyes; cheeks produced into a broad tooth posteriorly; 

 inner margins of the eyes subparallel but distinctly emarginate 

 opposite the antennae; face smooth, sparsely punctured; labrum 

 distinctly exserted; clypeus transverse, the apical margin truncate, 

 not depressed, the dorsal margin strongly curved medially; the third 

 antennae joint longer than the fourth and fifth combined; mesocatum 

 very long, without notauli, the anterior wings attached opposite the 

 posterior margin; scutellum convex, more or less pillow-like; pre- 

 pectal carina well defined but terminating well below the middle of 

 the anterior margin of the mesepisternum ; mesepisternum without 

 depressions, much longer (cephalo-caudad) than high; propodeum 

 partly areolated, rather long, depressed below the level of the meta- 

 notum; propodeal spiracle elongate, the inner margin curved; the 

 first tergite almost twice as long as the hind coxae, bent upwards 

 beyond the middle; ovipositor about half or less as long as the abdo- 

 men, somewhat compressed, tapering apically on both dorsal and 

 ventral margins, and with oblique furrows apically; hind coxae 

 slender, elongate, subequal in length with the hind femora but much 

 shorter than the first tergite; legs of normal length, the tibiae simple; 

 apical joint of the hind tarsi not especially lengthened, shorter than 

 the two preceding joints; claws rather stout, long, sharply bent
