Hence when wasps emerge in July, we know that they are the 

 second brood. We have the following data on the subject: 



Scelipkron ctumtntarium. 



Nest Uken. Date of emergencr. No. of insects.

The two tables above show that the first summer generation 

 goes through its life cycle in less than a month. Hence one 

 aui see no reason why, tmdcr the same climatic conditions, we 

 should not have another generation following this, covering 

 the July-August period, and this third generation leave behind 

 them the young which hibernate. 



It would be very difficult to solve this problem precisely, 

 since in the latter part of the summer the wasps of all the 

 generations are mingled in their work. 



Sjmooyinical Notes (Lep.). 



In a paper on New Heterocera by Frank Hatmbach, which appeared 

 in -otmrfogical Newt, VoL aXVI, p. 321, 1915, the author has 



Ui. cly croucd tevcral synonyms of Western species, owing to 



the iACL that some recently pobUahcd papers by Dr. Dyar and our- 

 selves have been apparently overlooked. 



' ' ' .is Haun. is a t)'nonym of Ercia desmialis B. ft 

 XI t. N. Am. Lcp. II (6) 22$, 1914). 



I'tainriiusia montoma Hatm. falls before Piathrausia karlequinalis 

 Dyar (Insccotor Insc Menst. I. p. loo^ 1913)- 



CaloM fukmsoma Haim. u the same species as Cordylofesa nigri- 

 htnciaiis B. ft McD. (ConL N. Hilt N. Am. Lep. If. (3) p. 134. 

 1913). 



Regarding Pyramsia kma<htualis Haim. we are in dnuht. hut as far 

 as can Ik- iu<li;ed by the figure the species looks suspiciously like a 

 Chrys. liadrs mmlUoMla Hist., which is in Dr. D>ar's list 



wronK' ' as a synonym of Aria statalis Grt. An examination 



of the venation should of course at once settle the question as to 

 whether the specie* is a ChrysauRid or a Pyraustid and we should be 

 glad to hear from Mr. Haimbach on the subject 



Amnrhia nfmselana Haim.. described from a single 9 should be 

 tr k'enus Platynota. The species is closely allied to 



»:: 1 and has been standing in the R.irncs collection 



1 imisciii-t name of Kearfott's; this never bavins been pub- 



zelana Wa'im. will of course replace it.— J. McDumnoogh,
