Female. — Apterous with well-developed legs possessing 5-seg- 

 mented tarsi and apical pair ol claws. Hind tibia with single short, 

 blunt spur. Other legs lacking armature. Antennae many-seg- 

 mented, simple. Abdominal plates darkly pigmented; body essen- 

 tially naked except for thin scattering of pale hairs and dense, posterior 

 ring of silky hairs. 



Female genitalia. — (Fig. 297.) Mostly membranous except for 

 three pairs long, slender apodemes, shortest and longest pair originat- 

 ing in last abdominal segment; third pair, medium length, originating 

 in penultimate segment. 



Discussion.— As pointed out by Tutt (1900), Dalla Torre (1929), 

 Bourgogne and Paclt (1948), and others, Haworth in 1812 proposed 

 the substitutive name Fumea for his genus Fumaria (1811), which 

 he thought was preoccupied by a genus of plants. Under present 

 circumstances, however, this is considered to be an incorrect procedure 

 as the names in botany and zoology are independent of one another. 

 Thus, by priority the genus Fumaria should be considered the valid 

 name, and it is so treated in this paper.

Male. — (Fig. 3.) Body, wings fuscous. Antennae (fig. 362) 

 with 18-20 segments. Apex of forewing rounded, that of hindwing 

 more acute. Scales (fig. 320) of cell in forewing broad with dentate

 slender. All veins of primaries separate except K3 and R4, which 

 are connate ; veins of hindwing all separate. Wing expanse 1 1-13 mm.
