Signiphofa Ashmead. 
Type, S. flavopalliata Ashin. Orange Insects, 1880, p. 30. 
Body robust ; ocelli 3, situated in triangle. Antenme 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 and 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 to a 
point opposite the stigmal. Hind -wings narrow and with very long and delicate 
cilia beginning beyond marginal vein and extending around nearly to hinder ba^e 
of wing. Middle tibia? with a number of stout 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. 
SlGNIPHORA OCCIDENTALS U. Sp. 
Female. — Length, 0'53mm. ; expanse, l'2mm. ; greatest width of fore- wing, 0'09mm. 
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, tibiae 
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 
antennae 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 ineso- 
scutum brown, leaving the yellow band to include mesoscutellum and metascutum. 
Described from two $ , three $ specimens reared by D. W. Coquillett, 
from Aspldiotus aurcmtii var. citrinus, from San Gabriel, Oal., Maj T 30, 
June 1 and 3, 1887. 
(6) APHYCUS IMMACULATUS n.sp. 
The sixth of the Bed Scale parasites belongs to another subfamily, 
the EncyrtinaB. 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
