[June 
end of upper cubitus and reaching up to radial branch. On 
the surface of wing about 12 large silvery white spots; 
about five tending to form a row across near end of stigma, 
one of which is in end of stigma and extends beyond to 
next vein, one in the base of radial fork, two behind it, 
and one in the median fork; about middle of length are 
two more silvery spots, and before this an interrupted band 
from costa just beyond subcostal cell, and extending across 
radius, and two spots nearer to base; hind wings fumose, 
veins darker. In fore wings the short, rounded scales are 
in pale areas, the forked scales densely placed to form dark 
areas. Both wings iridescent. 
Length 2.2 mm. 
From Barro Colorado Island, Panama, 23 June. A re-

Hemipsocus pretiosus sp. nov. 
Figure 5. 
Head dull yellowish, unmarked; antennae also, likewise 
the thorax, abdomen blackish above, femora dark, tibia 
and tarsi pale; head, thorax and antennae with moderately 
long, pale hair. Fore wings mostly brown; veins nearly 
black, the longitudinal veins with white spots, particularly 
prominent beyond the middle; two larger white spots on 
posterior margin just beyond the end of the cubital vein; 
veins with erect hairs arising from black spots; the vein 
bounding areola postica and the cross-vein above it are 
hyaline-white; hind wings grayish hyaline. Wings shorter 
than in H. roseus, but the venation is very similar, the fork 
of the median vein, however, reaches back to the cross-vein 
to areola postica or even onto the cross-vein. 
Length of fore wing 2.2 mm. 
One from Soledad, Cuba, 18 February (Myers) and the
