SIGNIPHORA Ashmead, 
Type, S. flavopalliata Ashm. Orange Insects, 1880, p. 30. 
Body robust; ocelli 3, situated in triangle. Antenne inserted at border of clypeus, 
6-jointed; scape reaching nearly to top of head; pedicel large, nearly as long as 
scape; funicle joints 1, 2, and 3 very small; club very long, undivided. Face round; 
mandibles strong, bidentate; labial palpi rudimentary; maxillary palpi 3-jointed. 
Fore-wings rather broad ana short; submarginal and marginal veins subequal in 
length; marginal thick; stigmal thinner and curved; marginal and stigmal veins 
with several long, stiff bristles; no discal cilia; marginal cilia very long and deli- 
cate, beginning on costal margin just beyond stigmal and extending around toa 
point opposite the stigmal. Hind-wings narrow and with very long and delicate 
cilia beginning beyond marginal vein and extending around nearly to hinder base 
of wing. Middle tibiw with a number of stovt bristles, apical spur as long as first 
tarsal joint and furnished on inner edge with five or six long bristles at regular 
intervals; front and hind legs unarmed. Abdomen broadly sessile, rounded at tip; 
ovipositor of female somewhat extruded, apical spiracles facing ventrally; male 
penis long, cleft at tip. 
SIGNIPHORA OCCIDENTALIS n. sp. 
Female.—Length, 0°53 mm. ; expanse, 1*2mm. ; greatest width of fore- wing, 0:09 mm. 
Antennal scape robust, reaching to middle of eyes; pedicel large, stout, rather more 
than one-third as long as scape; funicle joints 1, 2, and 3 subequal in diameter, very 
small, together only a little over one-third length of pedicel and considerably less 
than the tip width of pedicel; increasing in length from 1 to 3; club nearly as long 
as scape and pedicel together, long oval when seen from side, twice as wide as 
pedicel, narrow with parallel sides when seen from above, scarcely wider than 
funicle joint 3. Marginal vein with 6 strong bristles, stigmal with one, submar- 
ginal with one. Middle femora with a strong spine near inner side of tip, tibiw 
with three strong external spines, two near base and one near tip. Color (from 
balsam-mounted specimens only): Head, pronotum, metanotum and abdomen, dark 
brown, nearly black, eyes dark red; mesonotum bright lemon-yellow; all legs and 
antenne fuscous; mouth parts light-brown, mandibles tipped with black; wing 
veins fuscous; fore-wings with an indefinite fuscous patch occupying entire disc 
except at base and apical fourth. 
Male.—Resembles female, except that it is rather larger and has the entire meso- 
scutum brown, leaving the yellow band to include mesoscutellum and metascutum. 
Described from two 2, three 4 specimens reared by D. W. Coquillett, 
from Aspidiotus aurantii var. citrinus, from San Gabriel, Cal., May 30, 
* June 1 and 3, 1887.

(6) APHYCUS IMMACULATUS n. sp. 
The sixth of the Red Scale parasites belongs to another subfamily, 
the Encyrtine. Mr. Coquillett reared two specimens of this form from 
typical specimens of Aspidiotus aurantii October 11, 1887, and unfor- 
tunately mounted both specimens in balsam. The species has not been 
reared since, and hence can not be properly studied from dry mounts. 
Enough of its characters, however, are brought out in the balsam 
mounts to separate it from all described species. It is possible that 
this is the adult of an interesting parasitic larva which Mr, Coquillett
