ALLOCA.MPTUS. STAUKOPODOCTONUS. 375 



basal half less sinuate and two especially prominent lateral meta- 

 thoracic carinaB. 



The type was captured by Thwaites in Ceylon in 1873. 

 A female was bred in the Calcutta Museum from the larva 

 of a moth, Trabala vishnu, found on a castor-oil tree in that 

 city; it emerged from its host on 26th March, 1894. 



272. Allocamptus inflexus, sp. n. 



c? $ . A large, pale testaceous species, the only black marks being 

 at the base of the front wings behind the tegulse. Head narrow 

 behind eyes. Thorax with the metathorax finely and not very 

 distinctly traus-striate, with the stria3 laterally all equally strong. 

 Scutellum margined. Wings with a distinct glabrous area in first 

 cubital cell, the base of the radial nervure testaceous, strongly 

 Insinuate, and the costa and stigma testaceous. 



Length, $ 27 millim. ; tf 17 millim.

Type $ in the Oxford Museum. 



This species differs from A. slnuatus in its shorter and stouter 

 basal segment, more finely striate metathorax, distinct nervelet, 

 much shorter first discoidal cell, testaceous costa and stigma, with 

 the latter much broader and emitting the concolorous radius less 

 obliquelv and more directly. It is extremely like A. undulatas, 

 Grav., but I am able to distinguish it by the posteriorly very much 

 more narrowed head, the less basal ly sinuate and testaceous radial 

 nervure and the distinct nervelet, which is emitted from the 

 geniculate centre of the first cubital nervure, whereas in the latter 

 species it is geniculate, with no nervelet distinctly beyond the 

 centre ; the angle at which the stigma emits the radius and the 

 conformation of the basal segment is the same in both. 



The male differs from the female in nothing but its much smaller 

 size and more slender conformation ; it closely resembles Henico- 

 spilus flavicaput.

Clypeus apically transverse ; labrura prominent, apically roundly 

 constricted and often longer than half the clypeus. Abdomen 

 strongly compressed and more than double the length of the head 

 and thorax. Transverse cubital nervure angled shortly but dis- 

 tinctly below the centre; disco-cubital nervure roundly and 

 broadly curved, rising before the discoidal nervure ; nervelet
