men, the yellow triangularly produced at meson and two cross-stripes 
on abdomen near base, the first narrowly interrupted at the meson. 
Fore wings hyaline but centrally with a large round moonlike spot, 
whose center is opposite the distal part of the marginal vein, the 
stigmal vein not extending distad of its most distal circumferential 
point; postmarginal vein distinctly shorter than the stigmal, the 
venation yellow. Antenne dull brownish yellow, the scape and ped- 
icel metallic green (except bulb and base of the former and apex and 
ventral side of the latter). Funicle 1 two-thirds longer than wide, 
subequal to the pedicel, 2 a little longer than wide. Club with a dis- 
tinct terminal spine. Mandibles 5-dentate. 
Pronotum large, conical. Propodeum with a distinct median ca- 
rina, otherwise plane, the spiracles minute. Thorax scaly. 
Described from one female received from Wm. A. Hilton and 
collected at Laguna Beach, Southern California (C. F. Baker). 
Type: Catalogue No. 20173, U.S. N. M., the female on a tag, 
the head, a caudal leg and a fore wing on a slide. 
Perilampus chrysope Crawford. 
Three females, Claremont, California (C. F. Baker). Compared 
with types. 
Perilampus canadensis Crawford. 
This belongs in the first division of Crawford’s (1914) table, and 
is closely allied with swbcarinatus; but in the latter the lower face 
(laterad of the clypeus) is finely cross-wrinkled, but in canadensis 
it bears only a few punctures (and a line of smaller punctures up 
the eye margin) ; the lower cheeks are similarly sculptured for the 
respective species (that is, in swbcarinatus finely striate, and so on). 
The carina referred to in the table is the carinated edges of the 
large scrobicular cavity (with the species bearing it, the face is 
striate, otherwise smooth or mostly so). The carina is weak in 
robertsoni, which resembles similis, but there is more sculpture on 
the head in the former; in robertsoni the venation is pale, black in 
similis. The species subcarinatus and platygaster are very much 
alike, but the latter has larger punctures on the clypeus and the 
lateral margin is cross-wrinkled, while in the first species the clypeus 
is practically smooth and with minute scattered punctures; more-
