324 AMERICAN HYMENOPTERA. 



Gall-fly. Female. — Head, antennae, thorax and legs dark, reddish brown. An- 

 tennae fourteen jointed, the first and second large, the second three-fourths the 

 length of the first, the third one and one-half the length of one and two together, 

 the fourth equal to one and two together, and one-half as long as the third, sixth 

 to the thirteenth equal, fourteenth pointed, short and only half as long as the 

 thirteenth. Head short and broad; vertex hairy. Mesonotum small, narrow 

 and hairy, though in some individuals shining and without hairs on the vertex. 

 Collare very narrow and obscure, and with dense, fine, white hairs, and the ante- 

 rior border of the mesonotum apparently depressed. Parapsides present but 

 indistinct. Median lines absent. Scutellum small, hairy, hairs longer than on 

 the mesothorax. Fovae wanting. Abdomen large, shining black, second segment 

 with fine microscopic hairs on the sides anteriorly. The abdominal segments are 

 distinct and gradually shorter from the second, all compressed on the sides. 

 Anal segment with a tuft of long hairs. Legs dusky and more decidedly reddish 

 brown than the other parts of the body. Body .13, antennae .11, rudimentary 

 wings .05. These last are longer than in most supapterous species. No males. 



Named for the Hon. Charles W. Gillette, for many years my 

 genial companion in many an entomological ramble, and who col 

 lected the galls from which my specimens were bred from the ground 

 beneath a large white oak on his lawn. 



Callirhytis eeropteroides n. sp. 



Galls. — Slight enlargements of base of the annual growths of the 

 sin i. its of (/■ tinctoria. These swellings are often so inconspicuous 

 that it is very difficult to distinguish them from the unaffected 

 branches. Occasionally one is so developed as to attract notice. 

 They are polythalamous, though only a few insects are found in 

 even the largest. Found in July at Crescent Beach, Branford, 

 Conn. 



Gall-fly. Female. — Head shining, blackish brown, but with extremely minute 

 hairs and a fine wrinkled surface on the vertex. Antennae thirteen jointed, first 

 and second large and nearly equal in size, third one-fourth less in length than 

 the first two, fourth nearly as long as the third, and the following nearly equal 

 in length and, in color, all are a dull brownish red to a darker shade towards the 

 apex. Thorax black, shining but evenly transversely wrinkled, pleurae and 

 collare punctate. Parapsides converging from the collare to the scutellum. The 

 parallel intermediate lines extend halfway from the collare, a line over the base 

 of each wing, all poorly defined, being merely faint depressions breaking the sur- 

 face into longitudinal ridges. Scutellum smoother than the mesonotum. Fovae 

 large but shallow. Abdomen smooth, shining brown. Legs dark brown. Wings 

 hyaline, and the veins so faint and colorless as to make definition impossible, 

 even under a strong magnifier. Body .08, antennae .06, wings .08. 



Six bred specimens — all females.
