370 MONOGRAPHIA CHALCIDUM. 



rufi, supra pallide fusci ; tarsi flavi ; ungues et pulvilli fusci : alae 

 hyalinae ; anticae, ubi nervus solitus costam attingit fusco macu- 

 latEe, ubi ramulum emittit late fusco-fasciatae ; nervus fuscus, ubi 

 costam attingit incrassatus, ater ; ramulus ater. (Alarum longi- 

 tude, I2 lin. ; corporis 1 lin.) 



Taken near Stockton-upon-Tees, by the Rev. G. T. Rudd. 

 The Pentamerous Chalcides will form two divisions : of the 



first, the remaining families may be placed in the following 



order : 



Abdomen petiolatum Fam.IV. MiscoGASXERiDiE. 



Antennae monili- 



Ramulus stigma- formes Fam. V. Ormocerid^e. 



ticalis rectus. Antennae filifor- 



Abdomen mes fusiformes 



sessile. aut clavatae . . Fam. VI. PteromalidjE. 

 Ramulus stigmaticalis incurvus Fam, VII. CLEONYMiDiE. 



The second division includes the Eupelmidge, Encyrtidae, 

 and a few genera, composed of very minute species, which 

 connect the Encyrtidae with the Tetramera. The only one 

 yet described is Aphelinus, Dolman. 



Family IV. — Miscogasterid^.

Chrysolampus, Sphegigaster, Stilbula, Eucharis, and some 

 species of Halticoptera belong to this family.
