REPORT OF THE STATE ENTOMOLOGIST I907 389 



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 }i its diameter, the distal enlarge- 

 ment oval with a length H greater than its diameter; cir- 

 cumfili very faint, probably 3; dorsal plate deeply and narrowly 

 emarginate; bred from a iubglobular, densely haired hickory 

 leaf gall....(Cecidomyia) holotricha O. S., C. iiii 



DENTIFIBITLA n. g. 



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 i. 



Key to species 

 a Distal portion of the stem of the 5th antennal segment rather short, with 

 a length about 4 times its diameter; the 5th tarsal segment on the 

 anterior legs longer than the 4th 

 b Entire insect yellowish with the exception of a dark spot on the 

 dorsal part of the abdomen; wing hairs curved; antennal setae 

 rather fine, circumfili long. Taken on hickory, .c a r y a e Felt, 332b 

 bb Mesonotum yellowish brown, the remainder of the insect light yel- 

 lowish; wing hairs nearly straight; antennal setae coarse; cir- 

 cumfili rather short. Bred from Aspidiotus uvae 



c oc ci n. sp., C. 1018 

 aa Distal portion of antennal stem of the 5th segment long, with a length 

 about 5 times the diameter; 5th tarsal segment of anterior legs as 

 long as the 4th 



b Entire insect a pale yellowish orange. Taken on Viburnum 



v i b u r n i Felt, C. 210, 591 



LOBOPTEmOMYIA n. g. 



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 [pi. 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.
