Genxjs MARLATTIELLA Howard. 
Eore wings with an oblique hairless line; antenna) in the female 4-jointed, one small

normal. 
1. MARLATTIELLA ALEYRODESII Cameron. 
Cameron, .19.12, pp. 2 15421 6. 
I take the principal characters of this species from the original description: — Yellow; 
mesonotum and dorsum of abdomen reddish orange; wings hyaline; body smooth and shining; 
.submarginal vein longer than the marginal; scape a little shorter than the club. 
Habitat: Broken Hill, New* South Wales. 
Type: Unknown. 
Genus PLASTOCHARELLA Girault. 
Differs from Thysanus Ilaliday in having three true funicle joints (instead of three 
ring-joints, the funicle absent) and the marginal cilia of fore wings very short. Scutum and 
iscutellum with a median grooved line. Antenna* 6-jointed. Eore wings with an oblique hair- 
less line, densely ciliated. Male only. 
1. PLASTOCHARELLA FtJSCI PENNIS Girault. Male. Genotype. 
Orange yellow', the abdomen black, also the legs except the trochanters, knees, tips of 
tibia) and the tarsi; antenna) dusky, last two joints black; hind wings embrowned, clearer 
toward tip, tho fore wing similarly so but less clear toward tip, clear and nearly naked proxi- 
mad of the bend of the submarginal vein. Mesopleurum and tegula black. 
Habitat: Ingham, Queensland. 
Type: Ifo. Hy 1746, Queensland Museum. 
Genus MYOCNEMELLA Girault. 
Differing from all the genera of the subfamily in being 9-jointed antenna) with two 
minute ring-joints. With the habitus of A bier us Howard, the ovipositor strongly exserted for 
a third of the length of the abdomen; intermediate tibiae and first tarsal joint greatly, foliately 
flattened, also the femur somewhat flattened toward tip. Third funicle joint abruptly short and 
transverse, the funicle 3-jo'mted, the club 2-jointed. Hind femur compressed. Club somewhat 
as in the genus Aphelinoidea of the Trichogrammatidao. Marginal vein distinctly shorter 
than the submarginal. The male is not known. 
1. MYOCNEMELLA BIFASCIATA Girault. Female. Genotype. 
Dark metallic blue, the legs and antennae black; middle tarsal joints white; fore wings 
with two crescentric cross-stripes of brownish, one from the apical two thirds of the marginal 
vein (the broader), the other between the end of the stigmal vein and apex of wing; also a 
•spot proximad at caudal margin which is large and sends out an arm to the first cross-stripe. 
A patch of coarse cilia under marginal vein, distal half. Other discal ciliation absent except 
from distal stripe to wing apex and along caudal half or more of first stripe. 
Habitat: Capeville (Pentland), Queensland. 
Type: No. Hy 1747, Queensland Museum.
