A Synopsis of the Grenera of the Chalcididce, Subfamily Eucha-

Synopsis of the Genera o/Eucliarinse. 



I have here attempted to give a generic revision of the sub- 

 family EucJiarincBy which includes some of the most beautiful 

 and remarkable species of the Chalcididse. With few exceptions, 

 the sj^ecies are extra-European, and appear to be most numerous 

 in Tropical America and Australia. The species in the British 

 Museum represent at least fifteen well-marked genera, of which 

 only ten have been previously characterized. I have selected 

 only the most salient characters of each genus ; for minute and 

 detailed characters are unnecessary in the present imperfect 

 state of our knowledge of the subfamily. 



The Eucharinse are large, strongly-sculptured,metallic-coloured 

 Chalcididse ; the abdomen is always more or less petiolated, and 

 is frequently raised and comj)ressed, giving the insects some 

 resemblance to the Cynipidae. From the Perilampince, to which 

 they have some resemblance, they ma\^ be distinguished by the 

 longer petiole, the absence of the stigraatic nervule, &c.
