AUSTRALIAN HYMENOPTERA CHALCIDOIDEA, VII.—GIRAULT. 41 
delicate. Scutellum finely longitudinally striated, without an apparent cross-suture near apex. 
Fore wings quite as in Aphelinus; infusecated. Scutellum long. Like Aphelinus but the eyes 
convergent, the face inflexed, the antennz with a ring-joint, the middle tibial spur stout. 
1. EUTRICHOSOMELLA ALBICLAVA new species. Female. Genotype. 
Length, 0.80 mm. Honey yellow, the scutellum and abdomen orange yellow; face of 
pronotum, mesopleura, a stripe across base of abdomen and another across at distal three 
fourths, dusky. Fore wings stained under the marginal vein, the stain accented at apex of 
submarginal and stigmal veins. Thorax finely scaly. Discal cilia proximad of the oblique 
hairless line twice coarser than the main ciliation, about from 7 to 8 lines. Scape, pedicel, 
funicle 1 and the legs orange yellow; club white, rest of antenne yellowish white. Funicle 1 
shortest, a little wider than long, 2 and 3 subequal, each a little longer than wide. Pedicel 
long, two thirds the length of the funicle. 
Habitat: Gordonvale (Cairns) and Cooktown, Queensland. Jungle, May 8, 1913 
(A. P. Dodd) at Gordonvale (type). 
Type: No. Hy 2907, Queensland Museum, Brisbane, the specimen on a tag, the head on 
a slide. 
2. EUTRICHOSOMELLA MULTIFASCIATA new species. 
Female :—Length, 1.10 mm. 
Very similar to albiclava Girault but differing in the following particulars: The pedicel 
is distinctly longer, subelongate; the funicle joints are longer, 3 a little longer than 2; the 
caudal pair of the four bristles on margin of scutum are minute, not large, coarse and equal 
to the cephalic pair as in the genotype; the cephalic pair of bristles on scutum are smaller; 
the disc of scutum is naked, not with a half dozen or so scattered sete; the bristle on each 
axilla and the four on scutellum are all smaller; the scutellum is densely polygonally reticulated ; 
the axille meet inwardly, not rather widely separated; the abdomen bears about five cross- 
stripes of black; the fore wings are more uniformly infuscated, the infuscation only accented 
proximad of the hairless line at base of marginal vein and there rather indefinitely; the cilia 
proximad of the hairless line are finer and there are about eleven lines (only about six in the 
genotype); and the middle tibiwe are fuscous except at tips. The funicle is wholly white in 
both species, the hind tibiz fuscous below knees. The same otherwise. 
General color pale yellow. Cross-stripes on abdomen commencing some distance out 
from base. 
From one female captured from a window, December 14, 1912. 
Habitat: Gordonvale (Cairns), Queensland. 
Type: No. Hy 2908, Queensland Museum, Brisbane, the above specimen on a slide. 
3. EUTRICHOSOMELLA BLATTOPHAGA new species. 
Female :—Length, 1.15 mm. 
Very similar to albiclava Girault but not marked at all with black and the infuscation 
under the marginal vein of fore wing is very faint and uniform. Sides and venter of thorax 
lemon yellow. Only the abdomen and vertex is orange yellow. Cephalic femur swollen. 
Abdomen squarely truncate at apex. 
From many specimens reared with Blatticida ashmeadi from native blattid eggs, February 
(A. P. Dodd). Jungle. , 
Habitat: Babinda, Queensland. 
Type: No. Hy 2910, Queensland Museum, Brisbane, five females on a slide with type 
Blatticida ashmeadi Girault.
