 OF GENERATIONS IN CYNIPIBM.

Having bred a ? of Nematus miliaris on April 20th, I confined 

 her on a shoot of osier. Eggs laid by her were observed on May l7th, 

 and minute larvae on May 22nd ; by June 13th, the larvae were spun 

 up, and on the 16th, the imagines began to cnierge ; by the 20th all 

 had appeared — twenty-two in number, only one being a ? . From a 

 larva found on July 2Sth, I bred another ? on August 8th ; this also 

 I confined on sallow : she laid eggs which hatched, and the larvae were 

 half grown at end of month ; several of these larvae spun up in the 

 latter third of September. 



On May 2Gth, I bred a ? of Nematas palUdus, and confined her 

 on black poplar (the food of the larva she was bred from), on a leaf 

 of which she laid eggs about the beginning of June, the minute larvae 

 from which were noticed on the l7th, but they did not thrive, all but 

 two dying when nearly full-fed, these two attained the perfect state 

 at end of July — both males.
