scutellum dirty white or yellowish; antennal segments 3 to 8 

 dark at apex and light basally, 9 and 10 black; forewings opaque, 

 brown, small area at base and another at tip whitish, veins 

 tawny; between the veins rows of many, small, light-colored 

 patches, giving a very striking and characteristic appearance 

 to the wings. Body surface sparsely covered with rather long

 vated at posterior ocelli ; f rons scarcely visible ; front ocellus not

Thorax broad, robust, hairy. Legs rather short; front and 

 middle pairs of tibia? conspicuously flattened and somewhat fo- 

 liaceous and front femora somewhat flattened in distal half; 

 hind tibiae with a large, prominent tooth near apex. Forewings

Genus HETEROPSYLLA Crawford 



This American genus, comprising seven described species, is 

 a well-marked group. One species apparently abundant in the 

 South Pacific is closer to this genus than any other. Although 

 it differs in some important characteristics from the American 

 species, it is nevertheless included herein for the present.

Length of body, 2 millimeters ; length of fore wing, 2.1 ; length

 tarsi, metapleurse, and a small area beneath each eye pale ; sev- 

 eral streaks on thoracic dorsum white or pale; two longitudinal 

 rows of white spots on each side of abdomen. Body surface
