and centre of clypeus shortly produced. Antennae about half length of 

 body, nigrescent with scape flavidous beneath. Thorax black with only 

 a flavous callosity before radices ; niesonotum strongly punctate with the 

 notauli indistinct ; nietathorax coarsely rugose, with no lateral basal areae 

 Scutellum deplanate and laterally elevated. Abdomen piceous with the 

 first segment, except sometimes basally, red and the second nearly entire- 

 ly dull rufescent. Legs red with the anterior subllavidous ; hind coxae, 

 base of trochanters and of femora, apices of the latter and of tiie tibiae, 

 with the tarsi, nigrescent ; basal trochanteral joint the longer ; hind tibiae 

 stout and basally constricted ; metatarsus incrassate in both sexes. Wings 

 subhyaline with the stigma piceous, and tegulae concolorous or flavescent. 

 Length, 7-10 mm. 



Apparently very rare, (occurring in Sweden and (jermany. Fitch intro- 

 duced it as British (Entom. 1880, p. 255) on account of a single specimen, 

 bred b)' Weston from — .'' Kphippiphora obscurana in — galls of Cynips 

 Ko/lari, adding {l.c. 1884, p. 227) that VoUenhoven also raised it from 

 Halias cioraiui. 



GRAVENHORSTIA, Boie.

 p. 150. 



Face with a strong and acute tooth below the antennae ; clypeus 

 centrally acute at its apex ; ocelli small and eyes large. Alesonotum with 

 no distinct notauli ; nietathorax evenly rounded. Second abdominal seg- 

 ment as long as the first. Claws basally pectinate. Wings with the 

 second recurrent nervure emitted from the cubital distinctly a little before 

 the submarginal nervure, as in the Ophionides; radius not distinctly in- 

 crassate basally ; discocubital nervure evenly rounded. 



In every feature, but the usually considered important one of the second 

 recurrent nervure's emission from the cubitus before the submarginal, 

 this genus is entirely Anomaloid and 1 do not consider this point suffi- 

 cient — considering how closely Erigorgus approaches it — to place it in the 

 Ophionides, where the whole remainder of its sculpture and conformation 

 are incongruous, as was done by Ashmead and more recently by Schmie- 

 deknecht; Forster considered it a Campoj)legid, I know not upon what 

 grounds. 



Only one species is known of this conspicuous genus.
