slightly longer than the transverse cubital nermres ; the recurrent 

 nervure is almost interstitial with the second. The basal two joints 

 of the fore tarsi are as long as the tibiae. Hind coxae fully three 

 times longer than wide. 



XOBIDIXI. 

 GOXIOPEYMXUS, gen. nov. 



Antennae about the length of the thorax ; densely pilose ; the apex 

 with a 3-jointed projection, which sticks out at an angle ; the joint 

 from which it springs bears three stout longish spines, the middle 

 being the stouter. Between and above the antennae is a flat plate, 

 which, above, extends to the antennae, the upper part reduced to a 

 narrow keel, the lower part obUquely narrowed above. Ch'peus 

 roundly depressed. Mandibles curved, edentate. Labrtun large, 

 oblique, its apex rounded. Parapsidal furrows indistinct. Median 

 segment broadly rounded, closely reticulated, without keels, its 

 spiracles oval. Wings without an areolet ; the recurrent nervure 

 received shortly beyond the transverse cubital ; the transverse 

 median behind the transverse basal. Disco-cubital nervure not 

 broken. Transverse median nervure in hind wings broken very 

 shortly above the middle. The first abdominal segment becomes 

 gradually wider towards the apex ; it is more than twice longer than 

 the width at the apex ; the second and third have transverse furrows 

 near the apex ; the third has two oblique furrows which, with the 

 apical transverse one, form a triangle. Legs short ; the coxae longish ; 

 the tarsi shorter than the tibiae ; the calcaria and claws short. 



The ovipositor and palpi are long. Occiput transverse ; the edge 

 bordered by a projecting keel,' hollowed on the inner side. Eyes 

 slightly converging above ; the ocelli are placed well in front of theii' 

 hinder edge. Temples distinct, not narrowed. Pterostigma longish. 



The peculiar form of the antennae readily distinguishes this genus 

 from any of the known African or European genera of Xoridini. 

 A somewhat similar apical process is found on the antennae of the 

 Malay genera Epixorides, Cyaneoiorides and Spiloxorides, but these 

 genera are readily separated, inter alia, by the areolated metathorax 

 and by the different structure of the antennal whip.
