274 Notes on Some Parasites of Sugar Cane Insects etc. 
1. Gonatocerus bifasciativentris new species. 
Female: — Lensth, 1.20 mm. 
Black and golden yellow and belonging to the group of species 
with graceful fore wings, the abdomen as in rivalıs, the ovipositor 
exserted for a length equal to a third that of the abdomen. Funicle 
and club, the propodeum, cephalic third or less of mesoscutum, 
cephalic half of parapside (making two triangular spots on each side), 
a subquadrate spot at base of scutellum at the meson, immediate base 
of abdomen, exserted valves of the ovipositor and a broad black band 
just distad of center of abdomen, in the dorsal aspect sometimes narrowly, 
divided into two stripes, velvely black. Pedicel yellow, suffused with 
dusky, the scape yellow, dusky along dorsal and ventral edges. Meso- 
pleurum black. Fore wings with about 21 lines of discal cilia; mar- 
ginal vein long for the genus; posterior wings with a paired line of 
discal eilia around each margin. Funicle of antenna with no globular 
joints, all longer than wide, 1 and 2 subequal, smallest, 3 somewhat 
longer, subequal to the pedicel, 4, 5 and 6 subequal, longest, 7 only 
sligthly shorter than 6 while 8 shortens. Fore wings fumated slightly 
along distal margin. 
(From many specimens, °/s: inch objective, 1: inch optie, Bausch 
and Lomb.) 
Male: — The same but the abdomen sometimes with three black 
stripes. Longest funicle joints nearly thrice their own width, 
(From 8 specimens, the same magnification.) 
Though colored somewhat like. the Australian cingulatus and 
comptei, this species resembles in habits spinozai and bicolor of Australia 
and rivalis of North America because of the more slender abdomen, 
the exserted ovipositor and the absence of globate joints in the antennal 
funiele. But it is quite slender. Fight males and fifty-four females. 
Habitat: Java. 
Host: Eggs of a leafhopper embedded in the leaves of sugar cane. 
Types: In the Queensland Museum, Brisbane, 1 6, 16 ®’s on a slide 
in xylol-balsam. 
2, Trichogramma minutum (Riley). 
Four males, eleven females of this species reared from the eggs 
of Chilo infuscatellum Sn. 
3. A New Genus of Omphaline Eulophidae. Omphalin:. 
Parachrysocharis new genus. 
Female: — Like Ührysocharis Foerster but the postmarginal vein 
absent; antennae slender, three funicle and club joints, 
the third elub joint terminating in a spur. Stigmal vein 
long. Thorax without grooves, the parapsidal furrows 
complete. 
Male: — The same but the funicle 4-jointed, three club joints, 
10 antennal joints. Antennae clothed with long, fine hairs. 
Type: Parachrysocharis javensis new species. 
I. Parachrysocharis javensis new species. 
Female: — Length, 1.25 mm. 
Black, the base of the abdomen rather broadly, the ventral half 
of the thorax and the legs golden yellow; venation and antennae dusky
