tCynips. HYMENOPTERA. * 7 t 



Geoffroy, who has confined the genus Cynips 

 to fuch of the Linnsean fpecies as have antennae 

 containing no more than thirteen articulations, 

 and bent at their middle, or forming an angle, 

 obferves, that thofe infects have three (lemmata ; 

 that their antennae are cylindrical, and of equal 

 thiclcnefs in their whole length ; that their 

 under wings are fhorter than the upper ones ; 

 that their abdomen is nearly of an oval form, 

 acute underneath, a little flattened on the fides, 

 and attached to the thorax by a fhort ftalk or 

 pedicle, and that their (ling is not placed at the 

 extremity of their abdomen, but under that part, 

 between two projecting plates, which form a 

 kind of creft. This genus he has formed into 

 three families •, the firft containing thofe fpecies 

 in which the antennae are compofed of eleven, 

 the fecond thofe which have feven, the other 

 thofe which have thirteen articulations. 



He has arranged others of them, which have 

 filiform antennas not bent in their middle, an4 

 compofed of fourteen articulations, under a new 

 genus, which he terms DiploJepis ; thefe, how- 

 ever, do not feera to differ generically from the 

 Cynips, all the other characters aOlgned to 

 them .being the fame as in that genus : the 

 Jarvae of the two genera like wife perfectly 

 refemble one another, and Hye in the fame
