68 THE ENTOMOLOGIST. 



species of the thistle-galls. He speaks with certainty of 

 E. Rosae as being the cause of galls by oviposition on Rosa 

 centifolia. Of E. verticillata, Illiger (an Isosoma), he men- 

 tions as a synonym, in part, E. Abvotani, FoiiscoL, which is 

 said to destroy the larva of Cynips Rosae ; there appears to 

 be some confusion here. 



His Eurytoraa eenea has been since named Asaphes aenea, 

 and has little affinity with the Eurytomidae; he has observed 

 it to destroy Aphidius varius. It may be often reared from 

 the body of an Aphis, and, if it confines its attention to 

 Aphidius, it is the cause of much increase of Aphides, by 

 stopping the increase of their destroyers. His Euryloma 

 signata is a Decatoma, and may include more than one 

 species; he has reared it in July from the galls of Cynips 

 Quercus-gemma, Linti., and has observed it in September to 

 lay eggs in the oak spangles. As to Perilampus, he mentions 

 Dalman's belief that it is parasitic on wood-feeding insects, 

 and he includes Caratomus megacephalus with Perilampus, 

 1 have occasionally seen this species running over palings. 

 " Callimome regius," he says, "lives in the galls of Cynips 

 Qnercus; C. bedeguaris, in galls of the rose and of the oak 

 (the latter notice may refer to another species) ; C. Puparum, 

 in the galls of the rose, on the authority of Spinola; 

 C. muscarum, in the grubs of Aphidivorous flies ? (there may 

 be an error here, and another in the quotations given) ; 

 C. Capreae, in the galls of Cecidomyia, Schr., perhaps this 

 species is C. Cecidomyae, which has been observed by Dr. 

 Barnston, near Hudson's Bay." 



C. caudatus or C. difficilis is supposed by him to be 

 identical with Juniperi, which is a parasite of Lasioptera 

 Juniperina. C. globiceps, in galls of Cynips Potentillae, 

 Deff. Torymus fuliginosus, in the fungous many-chambered 

 galls on the twigs of oaks, on the authority of Spinola, appa- 

 rently the type of an unnamed genus. Eupelraus annulalus, 

 from the pupa of Cryptocephalus 12-punclatus ; he cites the 

 previously-described Diplolepis albicauda of Spinola as a 

 synonym of this species. E. Degeeri, in galls of Cynips 

 Potentillae. Cheiropachys quadrum, from the galls of Quercus 

 Tojae, on the authority of Spinola ; it is also parasitic on 

 wood-feeding insects. Pteromalus C)iiipedis, Linn., in galls 

 of the willow; two or three species are here included in one. 

 Pi. Apum, Reiz., in nests of some kind of bee.
