REPORT OF THE STATE ENTOMOLOGIST 1907 By, 
Oligarces Mein. 
Only one American representative is known; namely, O. 
noveboracensis Felt. This species was taken in July and 
presumably bred from material brought into the office. 
Brachyneura Rond. 
This peculiar genus is easily separated from Lasioptera, which 
it closely resembles in a general way, by the densely scaled fuscous 
wings [pl. 33, fig. 6]. 
Two American species of Brachyneura have been reared. One, 
B. eupatorii, was bred presumably from an oval swelling on

LASIOPTERARIAE 
This group presents a very characteristic appearance as the 
adults are almost invariably a dark brown and more or less orna- 
mented with silvery white. The antennal segments are cylindric, 
sessile and vary greatly in number. The wings have the anterior 
margin thickly scaled and the first two long veins are very close to 
the anterior border, except in the somewhat aberrant genus Trot- 
teria, and to a less extent in the peculiar Camptoneuromyia. A large 
proportion of the species breed in stem galls on woody or her- 
baceous plants, though the genus Baldratia exhibits a marked pref- 
erence for the characteristic blister galls of certain compositae. The 
one Camptoneuromyia reared, C. adhesa Felt, breeds in ovate 
galls between adherent leaves of Solidago canadensis or 
Se cemomimanand alsoint a loose apical bud call The latter 
may possibly be only a modified form of the more common ad- 
herent gall. The last named is also inhabited by Asphondylia 
monacha O. S. The transformations in this group appear 
to occur invariably in the tissues of the host plant.
