Descriptions of New (ieuera and Species 



of P.arasitic Hyiiienoptera taken at Ku- 



cliing, Sarawak, Borneo by Mr. Jolin 



Hewitt B. A. 



By P. Cameron. 

 (Continuation.) 



D i a p r i i n i. 



Loxotropa tricarinata, sp. n. 



Black, smooth and shining, the antennae except the 

 3-jointed club, the head, legs and abdominal jietiole 

 red, the wings hyaline, the nervures fuscous, the edges 

 of both longly, closely ciliated. Metanotum with a 

 stout central keel and a thinner one on either side 

 of it; the sides at the apex tuberculated. Scutellar 

 fovea large, wider than long, rounded at the base; 

 in front of it, bordering the apex of the mesonotum 

 is a straight, narrow furrow; the sides are bordered 

 by a narrow-flat margin or furrow. Base of metano- 

 tum raised , separated from the post-scutellum and 

 raised above the latter, forming in the centre a conical 

 protuberance. Abdominal petiole wider than long, 

 clearljr sef)arated, covered with white pubescence as 

 is also the collar and probably also the metathorax. 

 Antennae sparsely covered with stiff hairs; the basal 

 3 joints of the flagellum longer than the others, the 

 1st not much longer than the 2nd ; the last 3 much 

 thicker than the others, forming a clearlj^ defined 

 club; the last joint longer than the penultimate, 

 conical, the penultimate longer than the basal, which 

 is longer than wide. ?. 



Length 2 mm. 



In the forewings is a distinct basal cellule. In 

 having 3 distinct keels on the metanotum this 

 species differs from the described species of Loxotropa. 

 One species has been described as having 1 keel on it. 



Diabrinae. 

 Galesus cratocerus sp. n. 



Black, the legs inchning to piceous, their tarsi 

 testaceous; wings hj^ahne, longly ciHated, the ner- 

 vures fuscous ; they are Mghly iridescent ; smooth and 

 shining, the flagellum of antennae densely covered 

 with white pubescence. The metathorax and abdo- 

 minal petiole are densely covered with moderately 

 long (longer than that on the antennae) white pubes- 

 cence Ç. 



Length 2,5 mm. 



The 1st joint of the flagellum is as wide as long; 

 the 2nd and 3rd are the longest except the last; the 

 2nd one fourth longer than the 3rd, the 4th and 5th 

 wider than long, bot not much, the others to the last 

 wider than long, the last conical, as long as the 

 preceding 2 united; the last 5 forming a club, mder 

 than the others. Temples longish, obliquely narrowed; 

 the occiput transverse, stoutlj^ margined. Parapsidal 

 furrows \ndened towards the base. Scutellar foveae 

 large, deep, longish oval. Abdomen as wide as the 

 thorax. 



The head is transverse and stoutly keeled behind; 

 before the keel is a weakly crenulated furrow. The 

 parapsidal furrows are distinct deep and curved, 

 strongest at the base ; near the tcgulae is a shorter, 

 weaker furrow. On the basal half of the scutellum 

 are 2 oval foveae. There is a distinct, slightly curved 

 furrow along the top of the mesoplcurae. Metapleurae 

 aciculated, with an irregularly crenulated furrow 

 below. 



Scelionidae. 



Scelioninae. 



Apegusoneura gen. n. 



Post-marginal nervure long, distinct , one third 

 longer than the stigmal which is knobbed at the end 

 and obliquely sloped. Antennae 12 jointed in both 

 sexes, not thickened at the apex, the joints elongated. 

 OcelU in a triangle, the hinder separated from the 

 eyes by half the distance they are from each other. 

 Malar space two thirds of the length of the eyes. 

 Mandibles bidentate. There are 3 parapsidal furrows, 

 the lateral extending from the base to the apex, the 

 central wider and shallower, not reaching to the apex. 

 Scutellum wider than long, the apex broadly rounded. 

 Post-scutellum dejoressed , with 2 keels down the 

 centre, dividing it into 3 divisions or depressions. 

 Metanotum short, flat, margined at the apex above 

 and wth 2 keels down the centre. Abdomen shorter 

 than the head and thorax united, the sides keeled, 

 the basal 3 segments more strongly than the others; 

 the 3rd segment is the longest, being, if anything, 

 longer than wide; the others are wider than long; 

 all, except the last, are transverse at the apex ; the 

 basal 2 are striated, the basal strongly so. 



In the $ the 3rd joint of the antennae is thinner 

 than the others and is twice longer than \Aide; the 

 others are shorter and thicker, longish ovate, the 

 last longish conical, nearly as long as the preceding 

 2 united, in the S the antennal joints are more elon- 

 gate and not thickened. The distinctness of the 

 central mesonotal furrow jDrobably varies. The occiput 

 is transverse and margined ; the head is as wide as the 

 thorax; the front is depressed. 



In Dr. Kieffers table (Arm. Soc. scientifique 

 de Bruxelles, XXXII, 114) it runs to Iriteleia, from 

 which it may be known by the much shorter ab- 

 domen -with only the 3rd segment longer than wide. 

 Its nearest ally, I fancy, is Apegus Joer. nee. Kief., 

 which, like it, has the apex of the antemiae not for- 

 ming a club or thickened in the ?,but has the mandib- 

 les tridentate and the mesonotum with only 2 distinct 

 furrows. The central furrow is not quite so clearly 

 defined as it is shown by Mr. Brues in Hoploteleia in 

 Gen. Ins., Scelionidae PI. 1, f. 3. The neuration is as 

 in the latter Genus, as shown, 1. c. 



The 3 known Bornean species may be separated 

 by means of the following table. 



1 (2) Antennae black, the centre of mesonotum 



not keeled nigricornis. 



2 (1) Antennae fulvous, the centre of the mesono- 



tum keeled. 



3 (4) Mesopleurae longitudinally striated, the tegu- 



lae fulvous carinatus.
