hairs, making the feet all more or less black. (See Plate I, 

 Figures 1, 2 and 3.) 



Wivg — 4.5 mm. to 5.5 mm. long (.18 in. to 22 in.,) 2 mm. to 

 2.5 mm. (.08 in. to .1 in.) broad, hyaline, traversed by four 

 black cross bands. Base of the wing clear ; first baud beginning 

 opposite the sinus of the basal lobe, sloping backward and joining 

 the second baud about the middle of the posterior margin. Second, 

 third and fourth bands confluent in front and diverging backwards. 

 The dark bands are arranged so as to resemble the outlines of a 

 turkey, the band toward the body representing the neck and head, 

 the secoud the body, the third the legs and the fourth the tail. 

 The whole surface of the wing covered with minute hairs, those on 

 the bands black, the others clear. Margiu of the wing all around 

 and the subcostal vein armed with bristles. (See Plate I, Figures 

 1-2.) 



Perfect insect {male) — Same general color as the female but 

 smaller ; length 4 to 5 mm. (.16 to .2 in.) ; five instead of seven 

 segments to the abdomen, second, third and fourth segments only 

 banded with white. Wings shorter and narrower aud not spread- 

 ing so much behind when the fly is at rest ; abdomen of the 

 same general shape but smaller. (See Plate I, Figure 2.) Copula- 

 tory apparatus 3 mm. (.12 in.) long, yellowish browm ; the penis 

 coiled and with the auxiliary organs usually folded under the 

 abdomen in a broadly oval cavity which extends forward to the 

 middle of the fourth segment. The genialia are shown Plate II, 

 Figure 2. (Notes. — The eyes are sometimes variegated with 

 brownish and greenish patches. The fifth abdominal segment 

 is occasionally narrowly baoded with white. Sometimes the 

 white abdominal stripes in places involve the whole width of the 

 segment. The coloring at the angle of meeting of the first and 

 second pi'osimal bands in the wings is quite variable, from hyaline 

 through faint, dusky shades to black. The black bands are quite 

 variable in brightness. They seem to be brighter in the males.) 



Eggs — Length r.8 to .9 mm.,) (.032 to .036 in.) ; breadth (.2 to 

 .25 mm ) (.008 to .009 in.) ; white in the oviducts, but light yel- 

 low when taken from the fruit ; fusiform and about four times as 

 long as wide ; pedicelate at the end ; pedicel about one-twentieth 

 of the length of the egg, longer than broad and rounded at the 

 end ; pedicelate end broadest and abruptly sloping into the pedi- 

 cel ; other end more sloping. The shell of the egg at the pedi-
