Notes on Some Parasites of Sugar Cane Insects etc. 



]. Gonatocerus hifasciativentris new species. 

 F e m a 1 e : — Length, 1 . 20 mm. 



Black and golden yeilow and belonging to the group of species 

 ^vith graceful fore wings, the abdomen as in rivalis^ 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 triangulär spots on each side), 

 a subquadrate spot at base of sciUellum 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 yeilow, suffused with 

 dusky, the scape yeilow, 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 cilia around each margin. Funicle of antenna with uo 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 man}^ specimens, 73- ii^c^^ objective, 1*. inch optic, Bausch 

 and Lomb.) 



Male; — The same but the abdomen sometimes with three black 

 stripes. Longest funicle joints nearlj^ thrice their own width. 

 (From 8 specimens, the same maguification.) 

 Though colored somev/hat like the Australian cingulatus and 

 comptei, this species resembles in habits spinozai and bicolor of Australia 

 and rimlis of North America because of the more slender abdomen, 

 the exserted ovipositor and the absence of globate joints in the antennal 

 funicle. But it is quite slender. Eight males and fifty-four females. 

 H a b i t a t : Java. 



Host: Eggs of a leaf hopper eiybedded in the leaves of sugar cane. 

 TJy pes : In the Queensland Museum, Brisbane, 1 d, 16 9 's on a slide 

 in xylol- baisam. 



2. Trichogramma minutum (Rile}^). 

 Four males, eleven females of this species reared from the eggs 

 of Cliilo infuscatellum Sn. 



3. A New Genus of Omphaline Eulophidae. Omphalini. 

 Parachrysocharis new genus. 

 Female: — Like Chrysocharis Foerstev but the poslmarginal vein 

 absent; antennae slender, three funicle and club joints, 

 the third club 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. 

 ' T y p e : 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 yeilow; venation and antennae dusky
