egg boat and three pupal shells. This, he was informed, con- 

 stituted the sole takings and from these all the conclusions 

 reached by Dr. Dyar were drawn. In view of these facts 

 the following phrase in Dr. Dyar's paper becomes much more 

 interesting. "This source is not always easy to discover. The 

 writer made a third visit to Dublin in August, 1909, and ?<.'</.v 

 able to discover an extensive breeding place of the species."'' 



Mr. Grossbeck carried on his explorations for several days 

 and found many egg boats as well as a full grown and recently 

 hatched larva in the area in which Dr. Dyar had found his 

 specimens. He also found egg boats in the electric light 

 swamp pointed out by me as a probable breeding place, in 

 spite of Dr. Dyar's statement that "Oviposition at present is 

 therefore impossible here." Two other breeding places were 

 located, one small, probably the place referred to by Dr. Dyar, 

 and one very large and well within the range of perturbans fly- 

 ing powers. The matter is therefore not quite so simple as 

 Dr. Dyar would have the inhabitants of Dublin believe. 



Dr. Dyar credits previous work on perturbans development 

 as follows : "The breeding habits of this species are peculiar. 

 Fortunately they are now known, through the timely discovery 

 of Mr. J. T. Brakeley, at Lahaway, New Jersey." In "Ent. 

 News" XIX, 22, January, 1908, I published all that was then 

 known of perturbans, showed that the first egg boats in nature 

 were found by Mr. Grossbeck, and credited Mr. Brakeley with 

 being the first to find larvae actually attached to roots. The 

 further work on the development of the larva was done by 

 Mr. Grossbeck who also published, in December, 1908, "Ent. 

 News" XIX, p. 473, the characters and habits of the pupa. Mr. 

 Brakeley has published nothing and all the information con- 

 cerning the breeding habits of C. perturbans comes from Mr. 

 Grossbeck or myself. 



With these few explanations and additions I trust that the 

 scientific and practical value of Dr. Dyar's paper will be better 

 appreciated.
