 TACHINIDAE REARED BY THE LATE GEORGE DIM- 

 MOCK, WITH DESCRIPTION OF ONE NEW SPECIES 

 AND NOTES ON THE GENUS ANETIA ROBINEAU- 

 DESVOIDY

Several years ago Dr. George Dimmock gave to the United States 

 National Museum a series of reared insects with his notes upon them. 

 Many rearings of Tachinidae were included, the records for which 

 were mostly unpublished. I planned to prepare the list for publica- 

 tion, but Avas obliged to await the appearance of Mr. Webber's revi- 

 sion of the genus Achaetoneura, as he was describing several of the 

 species as new. The present paper lists the species as the lots were 

 numbered by Doctor Dimmock, with a few necessary notes and the 

 description of one new species. Several of the species are repre- 

 sented only by puparia, which have been identified for me by my 

 colleague C. T, Greene, who has made an extensive study of the 

 characters of early stages of Diptera. 



A. REARED FROM LEPIDOPTERA 



148. From Sphinx chersls Hiibner. Cambridge, Mass., 1882. Pu- 

 paria found in soil where caterpillar tried to pupate. Three females, 

 identified by Webber as Achaetoneura frenchii Williston, " var. ? " 



246. From Amphidasis cognataina Guenee. Wachusetts, Mass., 



1882. Pupa only. Determined by Greene as Exorhta larvarniTm 

 Linnaeus {Tachina mella Walker). 



423. From Drepana hilineata Packard. Cambridge, Mass., June, 



1883. Pupa only. Greene finds that the puparium is different from 

 2iny in the National Museum, and hence can not identify it. 



505. From Danaus archippus Fabricius {Anosia plexippus Lin- 

 naeus of literature). Cambridge, Mass., emerged August 3, 1883. 

 One male, four females. Achaetoneura archippivora Williston. 



570. From Sphinx chersis Hiibner. Cambridge, Mass., emerged 

 June 13, 1884. Nine males and two females of Sturmia incompta 

 Van der Wulp. The species was described as a Brachycoma^ and 

 inquinata Van der Wulp is a synonym of it, as I found from the
