CAMPOPLEX. 451 



closely punctate and not very narrow posteriorly ; frons simple, 

 and the scrobes a little elevated externally ; mandibles, except at 

 apex, testaceous and basally as broad as the cheeks; palpi black. 

 Antenna? immaculate, with the basal flagellar joints not discrete. 

 Thorax with the metanotum finely scabrous and not at all 

 impressed, with no trace of carinaa ; spiracles elongate. Scutellum 

 coarsely punctate, and not carinate. Abdomen obsoletely punctate, 

 black, with the third, fourth, and base of the fifth segments bright 

 red ; postpetiole linear and hardly broader than the petiole, 

 valvulae large and exserted. Legs black, somewhat slender, with 

 only the front coxae apically, their femora and tibiae internally, 

 testaceous. Wings hyaline, with the tegulae and stigma black ; 

 areolet vertical, somewhat broad, with its petiole hardly a fourth 

 the length of the internal nervure, external nervure straight, 

 emitting the recurrent uervure from distinctly before its centre : 

 radius externally sinuate, lower basal nervure elongately post- 

 furcal ; lower wings with basal abscissa of radius half as long 

 again as recurrent; nervellus neither geniculate nor intercepted, 

 but slightly curved below. 



Length 9 milliin. 



UNITED PROVINCES : Mussoori, 7000 ft., x.06 (H. M. Lefroy). 



Ti/pe in the Pusa collection. 



In size and coloration it closely resembles 0. zonatus, but the 

 conformation of the areolet, etc., is very distinct. Its facies 

 closely resembles that of C. lapponicus, Holmg.
