men polished and shining. Legs dark, translucent brown. Wings hyaline; 

 veins faint and slender. Radial area open, broader than usual. Areolet want- 

 ing. Body .05, antenna? .05, wings .07. 



Dryophanta longicornis n. sp. 



Among the galls from which Andricm exiguus n. sp. and Neuro- 

 terus exiguus n. sp. were bred were three or four of an altogether 

 different sort. They were moderate enlargements of the upper por- 

 tion of very young and tender shoots, not at all prominent ; and 

 now that these shoots are dry and shrunken I am not able to 

 indentify them among the galls in the box. I did not separate 

 them at the time, supposing them to be too immature for develop- 

 ing, and I could not have done so without injuring the other spe- 

 cies. Of course I am not sure that the three large flies found in the 

 box came from these galls, but the presumption is that they did so. 

 At any rate, the flies are of an undescribed species, and their rela- 

 tion may be determined later. 



Gall-fly. Mule. — Head black. Antenna? long, fifteen jointed, first and second 

 short, globose and of equal length, third is one-third longer than the first two, 

 fourth equal to the first two, fifth almost equal to the fourth, the following grad- 

 ually shorter, and all of a dark brown color. Thorax black and shining in that 

 portion within the deep parapsidal grooves. Median and alar lines wanting. 

 Scutel lu id coarsely rugose and with short, scattered hairs. Fovse obsolete, but a 

 slight depression takes their place, this is rough like the rest of the scutellum. 

 Abdomen black and smooth. Legs rather pale red or reddish brown. Wings 

 large and smoky brown ; veins all distinct and reddish brown. Radial area open. 

 Areolet present. Cubitus full length, but slender towards the first transverse. 

 Body .09, antennae .11, wings .12. 



Female. — Body .10, antennae .11, wings .12. 



Two males and one female. 



Dryophanta pallipes n. sp. 



Galls. — The rapid Spring growth of thrifty young white oak 

 shoots is sometimes suddenly checked by the appearance of this 

 gall at their apex. The gall does not prevent the development of 

 the leaves below it, but immediately surrounding its base half a 

 dozen or more brown, thread-like bodies from three-fourths of an 

 inch to an inch and a half in length appear. Occasionally two or 

 more of these are narrowly strapped shape, and suggest that they 

 are all undeveloped leaves. The gall, a mere larval cell at the 

 center of this cluster, is blackish brown, thin shelled, oblong-oval, 

 .09 of an inch in length and .06 in diameter. The insect emerges 

 from the apex of the cell, leaving it resembling an eggshell with
