The members of this genus present a wide range in the number 

 of antennal segments, those of the female varying from 16 in the 

 case of L. flavescens to 33 in L. querciflorae. The 

 Australian L. nodosae Skuse is recorded as having 34 antennal 

 segments in the female. The segments of the male antennae vary 

 from 16 in L. 1 y c o p i to 21 or 22 in the male of L. d e s m o d i i . 

 Some species have the same number of antennal segments in both 

 sexes, while in the majority the female possesses two to four or five 

 more than the male. There seems to be no law governing this 

 variation. Certain of the females possess a group of heavy, stout, 

 recurved, chitinous hooks on the dorsum of the lobes of the ovipositor. 

 This peculiar structure is present in several rather widely separated 

 forms. Type Cecidomyia albipennis Meign. 



The species belonging to this genus breed for the most part in 

 more or less irregular subcortical galls on the stems of both herbaceous 

 and woody plants. An interesting form, L. caulicola, has been 

 reared from apparently normal Diervilla stems. All species of this 

 genus appear to winter in their galls. Those which live in herbaceous 

 stems emerge, as a rule, in early spring, while the forms subsisting 

 upon woody stems are more likely to fly during June. A few species
