Eleventh Report of the State Entomologist 165 



In the male the petiole of the terminal segment of the antenna is very- 

 short or wanting (PI. I, fig. 3). In the female the apical segment is 

 much longer and apparently double, as a slight constriction divides it; 

 arrangement of setce and processes somewhat verticillate (PI. I, fig. 4). 

 The male antenna is composed of 14 segments, and an equal number 

 obtains in the female if the terminal, semi-double segment be counted 

 as one. The discrepancy in earlier writers is due to difficulty in see- 

 ing all the segments and possibly to variation in the number in some 

 individuals. 



In the specimens before me the transverse veinlet is absent, unless it 

 is represented by a chitinous process near the basal sixth of the first 

 longitudinal. The third longitudinal vein (cubitus) is not forked, but is 

 as represented; its tip curving to the hind margin of the wing (PI. I, 

 fig. 2). The empodium is large; lateral aspect suboval; ventral aspect 

 triangular; claws strongly curved (PI. I, figs. 5, 6). The terminal seg- 

 ment of the male is subquadrate, relatively small, and is carried with its 

 tip turned upward; the large subtriangular clasps bear a number of long 

 sets and numerous very fine ones (PI. I, fig. 7). 



Its Chalcid Parasites. 



From galls received through the kindness of Mr. Peter Inchbald of 

 Fulworth Grange, Harrogate, England, three species of Chalcid parasites 

 were obtained, which were determined by Mr. Howard, as Torymiis sp., 

 female, Tetrasiichiis sp., and Entedon sp. — one female and five males. 



Some galls, gathered in Albany on March 21st, which had begun to 

 disclose their imagoes on May 5th, also gave out quite a number of 

 Chalcid parasites, the first of which made their appearance on April 28th. 

 Others emerged about the middle of May, and continued to appear until 

 the 25th of June, the last date recorded. These were also submitted to 

 Mr. Howard, who found them different from those bred from the exam- 

 ples received from Europe, and for which a new genus would probably 

 have to be founded. In some characters they come close to Merisus, of 

 which Dr. Riley bred and described two species from Cecidomyia 

 destructor, but they are separated from this genus by the metanotal and 

 claval characters.
