NEW ICHNEUMONID^ FROM BORNEO. 83 



close to Xylophrnrus, which may be known from it by the trans- 

 verse median nervure being broken beloiv the middle. 



In size, form, and coloration this genus resembles Allostomus 

 here described, but may readily be separated from it by the semi- 

 circular oral opening, and by the presence of an areolet in the 

 fore wings. In Ashmead's tables the genus runs near to Gabimia 

 and Xylophrurus, with neither of which has it any close relation- 

 ship. 



Paraxylophruriis maculiseutis, sp. nov. 



Black ; face, under side of antennal scape, the lower side of pro- 

 pleurae, the line dilated at the base, the apex gradually narrowed, 

 tegulge, the scutellum except the basal slope, the mark rounded at the 

 base, a semicircular mark on apex of post-scutellum, tubercles, a 

 small mark below the hind wings, the first abdominal segment behind 

 the spiracles, and lines on the apices of all of them, lemon-yellow. 

 Legs of a brighter lemon-yellow ; the apical two-thirds of the hind 

 coxge above, the basal three-fourths of the lower side, the apical joint 

 of their trochanters and a band between the middle and apex of the 

 hind tibiae, black. Wings hyaline, the stigma and nervures black. ? . 

 Length, 13 mm. ; terebra, 7 mm. 



Kuching (John Hewitt). 



The antennae have a broad white band in the middle. Head, 

 pro- and mesothorax smooth and shining, the metathorax closely 

 reticulated all over. Abdomen smooth and shining. The four 

 anterior tarsi and the apex of posterior fuscous. Tarsi closely 

 spinose. 



Allostomus, gen. nov. 



Wings without an areolet ; neither the disco-cubital nor the 

 second recurrent nervure broken by a stump ; transverse median 

 nervure received very shortly beyond the transverse basal ; transverse 

 median nervure in hind wings broken distinctly above the middle. 

 Eyes large, converging below, reaching close to the base of the 

 mandibles. Clypeus separated from the face, bounded at the sides 

 and below by furrows, the lateral furrows the wider and ending above 

 in a fovea. Mandibles unequal, edentate, bluntly pointed. There is 

 a tubercle above and between the antennae ; the latter are as long as 

 the body. Temples well developed, roundly dilated ; occiput mar- 

 gined, roundly incised. Mesonotum trilobate. Metanotum longish, 

 closely reticulated, the spiracles placed behind the middle, longish 

 oval, about three times longer than wide. First abdominal segment 

 longer than the second, its base half the length of the apex. Legs 

 (including the four hinder coxae) long, slender ; the base of the tibiae 

 not contracted. The antennae are broadly ringed with white. There 

 is a long ovipositor. The prothorax broadly projects laterally, and 

 is thus clearly separated from the mesothorax. Calcaria short. Claws 

 conspicuous, curved. There are eight abdominal segments. 



A distinct genus. In Ashmead's arrangement it comes in 

 near Clepticus and Epixorides, with neither of which can it be 

 confounded. Lethulia, Cam. (from Borneo) has three areae on 

 the metanotum, the abdominal petiole is longer than the follow-
