116 MONOGRAPHIA CHALCIDUM. 



but the formation here described is pecuhar to this family, and 

 to Leucospis, Thoracanthus, Smiera, Dirhinus, Chirocera, 

 Chalcis, Haltichella, and their affinities. These genera are 

 distinguished by their gibbous bodies, large coxae, and incras- 

 sated posterior thighs. The species are chiefly extra-European, 

 and among their number are some of the largest in the 

 whole tribe. Their natural situation I imagine to be imme- 

 diately following this family ; but having few genera or 

 species, I shall leave them for examination to some future 

 opportunity.

Dalman divides his genus Torymus (named Callimome long 

 before by Spinola) into three sections, the second one sub- 

 divided, viz. 



A. (Megastigmus.) Stigma incrassatum magisque determi- 

 natum • collare majuscuhim : corporis color non metallicus. 



B. (Torymus propr.) Stigma par viim ahhreviatum ; corpore

 (b.) Fe?noribus omnibus miiticis. 



C. (Anomali.) Corpore breviorCy abdomine gibbosiore, ovi- 

 ductu 71071 exserto. 



I have reserved his name, Torymus, for the first division of 

 his second section ; '^the other division is Callimome, Spinola. 

 It is not unlikely that his third section is allied to Ormyrus, 

 Westwood.
