ccc Abdomen pale yellowish; 5th antennal segment having the 
basal portion of the stem with a length equal to its diameter, 
the distal part with a length 34 its diameter, the distal enlarge- 
ment oval with a length ™% greater than its diameter; cir- 
cumfili very faint, probably 3; dorsal plate deeply and narrowly 
emarginate; bred from a subglobular, densely haired hickory

This group comprises a number of forms easily separated 
from the more typical species referred to Contarinia, by the 
conspicuous, triangular apical process on the basal clasp seg- 
ment, the terminal clasp segment is therefore subapical. All of 
the species are small pale yellowish forms. The wing is represented 
on plate 38, figure 1.

LOBOPTEROMYIA Il. &. 
This genus comprises a number of very distinct forms easily 
separable from Contarinia, to which they are closely related, by 
the broad wings. These organs have a conspicuous, broadly 
rounded extension posteriorly, making the width about % the 
length [pl. 38, fig. 3, 4]. The antennae are also peculiar in that 
the basal portion of the stem on the flagellate segments rarely has 
a length equal to its diameter. The enlargements are relatively 
large, subglobose, and the circumfili rather short, stout and uniform.
