fruit on the cultivated currant and gooseberry. The adults are 

 most abundant late in June, when they may be found in consider- 

 able numbers around currant and gooseberry bushes. The eggs 

 are deposited in the berries in which the larvae feed until full 

 grown, of course destroying the berries, and usually causing 

 them to drop to the ground. There is but a single generation 

 each year, the insect passing the Winter in the pupa state in the 

 ground or underneath rubbish under the bushes. In a bulletin, 

 soon to be issued by this Station, the life-history of this insect is 

 given in detail under the popular name of the Dark Currant Fly 

 to distinguish it from the other currant fly (Epochra canadensis) 

 which also occurs quite abundantly throughout the State.

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 

 OF THE GLOBE. 



Pictures for the album of the American Entomologicel Society have 

 been received from Charles F. Goodhue, Webster, N. H., and Charles

Your journal is indispensable to working entomologists, either in 

 applied or purely scientific fields, and I find the pages devoted to notes 

 on Entomological Literature very convenient for reference. — Mary E.

The volume of News for 1897 was duly received. The eight volumes 

 of the News form the most valued portion of my entomological library. 

 They are valuable for reference, entertaining to read, and pretty to look 

 at. — A. W. Pearson. 



Odonata. A Synonym and the bearing of its discovery on the 

 classification of Agrion. — An examination of some material from 

 Mexico, recently collected by Mr. Otis W. Barrett, has shown me that the 

 species which I described as Ischnura exstriata (Proc. Calif. Acad. Sci. 

 — 2 — iv, p. 493, 1895) is specifically identical with Agrion denticolle Bur- 

 meister, the type of which latter exists at Halle, Germany, where I have 

 studied it. Denticolle is referred by Baron de Selys to the genus Neha- 

 lennia, a genus belonging to that section of the " grand genre Agrion" 

 in which the females have no apical ventral spine on the eighth abdominal 

 segment. Ischnura belongs to the section in which such a spine is pres- 

 ent. There is no doubt that the female type of /. exstriata possesses 

 this spine, nor is there any reason for disbelieving that the females of den- 

 ticolle seen by de Selys lacked it. Burmeister's type, which de Selys did 

 not see, has a suggestion of such a spine, while among Mr. Barrett's 

 specimens are some females with, others without, this spine. I have no
