possession, of two of the genera of Evaniadae, and shall then go on 

 with the Aulacidse. 



Section I. Petiole of abdomen abrupt, and inserted at the superior extremity 

 of raetathorax ; claws with a tooth beneath. 



Genus 1. — Evania, Fah. 

 Type. SpJiex appendigaster, Linn. Many species known. 



Genus 2. — Brachygaster, Leach. 



Type. Evania minuta, Oliv. 



As a brief generic characteristic in addition to that contained in the 



table above, and which the accompanying wood-cut 



j^^^^^^ illustrates, it may be observed that the face is more 



^^_^^ prone than in the following genus, the metathorax less 



gibbous, and the antennae filiform. 



^. Br. minuta. 



Evania minuta, Oliv. *Ency. Method.' vi. 453. 

 Inhabits Northern Europe. There are English specimens in my 

 own collection. 



2. Br. Xanthops. Nigra : facie, genis, antennarum articulo prime 

 subtus, pedibusque quatuor anticis flavis. Mas. Long. 2^ lin. 

 Inhabits Brazil. In my own collection. 



Genus 3. — Hyptiam, Illiger. 

 Type. Evania petiolata, Fabr. 



The annexed wood- cut shows the character mentioned in the table, 

 to which may be added that the antennae are slightly 

 subclavate, head vertical, and metathorax dispropor- 



^^-^^^^-^ tionately large and very abruptly truncated. The chief 

 sexual distinction appears to be a slight difference in 

 the length of the scape of the antennae, and theu' being rather more 

 clavate in the female.
