172 
stout, about a half longer than its apical thickness, but longer than the 
first two funicle joints combined, the false ring-joint seen in the female 
absent or greatly reduced; funicle with only three transverse joints, the 
third very short or over thrice as wide as long; club very large, solid, 
elongate oval in shape, its dorsal outline convex, but the ventral side 
straight, widest at the middle, where it is about one-third wider than the 
last funicle joint, and in length equal to about twice the pedicel and 
funicle combined. 
Abdomen smaller than in the female, hardly more than one-half as 
long as the thorax, more acute at the apex, and usually strongly depressed 
above and beneath. 
Other structural characters closely approximating those of the female 
sex, except that the frontovertex is much more opaque with finer, closer 
thimble-like punctures. 
Coloration similar but not metallic, and with less yellow on antennae 
and legs, the head, thorax, and abdomen being black and only moder- 
ately shiny; antennae and legs fuscous to blackish, the apex of the front 
tibiae, apical half of middle tibiae, and front and middle tarsi brownish 
yellow, the hind tibiae slightly yellowish, the hind tarsi yellow beneath, 
and more or less fuscous above; wings hyaline and not distinctly stained 
with yellowish as in the female. 
Length, (0.82 to) 1.23; length of head, 0.497; width of head, 0.544; 
width of frontovertex, 0.172; width of mesoseutum, 0.535; length of 
antenna, 0.613; length of forewing, 1.09; width of forewing, 0.487 mm. 
Characters taken from a large series of females and six 
niales reared from Pseudococcus virgatus (Cockerell), or asso- 
ciated with this host, Honolulu and vicinity, Oahu, and five 
females from Manila and Los Banos, Philippines (George 
Compere, Fullaway, and H. E. Woodworth). The males were 
captured on September 11 and 13, 1916, on vines of the velvet 
bean, heavily infested with Pseudococcus virgatus, and on 
which the females of imsularis were very abundant. 
This parasite is presumably distributed throughout the low- 
lands of the Hawaiian Islands, although recorded specifically 
only from Oahu hithertofore. It has been stated that it was 
taken by Blackburn, however, on several of the Islands, and 
i have seen females from Olowalu and Wailuku, Maui. 
LirE History. 
Blepyrus insularis is parasitic only in Pseudococcus virgatus 
(Cockerell) so far as known. Females that were supplied 
with Pseudococcus longispinus (Targioni) oviposited rather 
freely, but no offspring were reared, the eggs or newly hatched
