irnknowxi to me. The sp<icies is certainly not a true TelenomiiH, and 

 appears to me, judging from liis description, a Ceraphronid. 



TRISSOLCUS Ashinead. gen. nov. 

 (Type T. brofhi/memr. Asbin.) 



Head very large, transverse, niucli broader than the thorax, the frons 

 convex, the occiput deeply concave, the upper edge of which is sharp. 

 Ocelli 3, triangularly arranged, Avidely separated, the lateral a little 

 distant from the margin of the eye, and <onne(>ted with it by an oblique 

 grooved Ihie. Eyes large, subovate. 



Antenuje inserted close to the moutii, in 9 ll-jointed, davate, the 

 funiele .S-jointed, the club (J-jointed. in i 12-jointed, filiform, with the 

 flagellar joints moniliform or submoniliform, pubescent. 



Maxillary palpi 3-jointed. 



Mandibles bifid. 



Thorax short, ovoid, convex, the collar not visible from above, the 

 mesonotum with 3 furrows abbreviate*! anteriorly, the scutellum semi- 

 circular, the metathorax very short. 



Front wings pubescent, the marginal vein usually sluut, the stigmal 

 vein rather long, oblique; postmarginal long. 



Abdomen broadly oval, depressed, subsessile, the second segment tbe 

 longest, but always broader than long. 



Legs as in Telenomus. 



This genus is closely allied to Telenomus, but is leadly distinguisiied 

 by the three abbreviated mesonotal grooves, broader head, and the wide 

 second abdominal segment. 



It seems to be i)arasitic only on the eggs of plant bugs belonging to 

 tlie family Peutatouiidfv. 



Our species may be thus tabulate<l:
