This large species breeds in fruitlike enlargements of the prickly 

 pear or Cactus. The galls were taken by' Mr H. K. Morrison at 

 Fort Grant, Ariz., and were received at the bureau of entomology 

 May 5; 1882 and figured in " Nature " for November 23, 1882, 

 page 77. The figure referred to illustrates a somewhat pear-shaped 

 gall about 16 cm. long and 8 cm_ in diam.eter. Mr Morrison states 

 that this gall appears to be rare, though the species of Cactus upon 

 which it occurs is abundant. All the galls he observed were on one 

 plant and contained hundreds of larvae May 5th. Pupae had forced 

 their way out, some even penetrating the stout paper in which the 

 galls were wrapped; the living adults were characterized as being 

 dark gray with black eyes, the legs and halteres reddish. Koebele 

 reared this species from seed pods of Cactus at Los Angeles, Cal., 

 in March 1886. Another lot of supposedly the sam.e species was 

 received May 31, 1899 from Bayfield, Col., through C. F. Baker 

 and adults, as in the previous case, issued during transit. 



Gall. The galls are very large and resemble somewhat the fruit 

 of the prickly pear. They are yellowish and in places somewhat rose 

 colored, without thorns, except at the base, very fleshy and decay 

 easily. 



These data have been drafted from the notes of the bureau of
