ousts (Acrydiinae), illustrating the retention of a nymphal 

 type of pronotum in adults of several species. The tegmina 

 and wings could be seen on careful examination, but being, 

 largely hidden under the pronotum they could be easily over-! 

 looked and the specimens mistaken for nymphs. This condi- 

 tion of the pronotum is known to occur in four species of two 

 genera, two of the forms being African, one Australian and 

 the other, which is new, as far as known, is only found in the 

 southeastern United States. 



Mr. Laurent called attention to a beautiful variety of Colias 

 caesonia described by Jerome McNeill in the Canadian Ento- 

 mologist for 1889 as Colias caesonia variety rosa. The speaker 

 stated that this variety was found in many of our large collec- 

 tions intermingled with Colias caesonia. The specimen in his 

 own collection had been attached to the label Colias caesonia for 

 more than twenty-five years, until Mr. Roswell C. Williams 

 called his attention to its being the variety rosa. Specimens of 

 Colias caesonia, as well as variety rosa were exhibited.
