'GEtfOTFPE, Campo pleas decipiens, Gray. 



Head transverse and not buccate ; clypeus not discrete ; 

 mandibles of normal breadth, with the teeth of subequal length ; 

 eyes internally strongly emarginate. Antennae filiform and hardly

 petiokr area not excavate ; spiracles elongate and not circular. 

 Scutellum deplanate, subquadrate and not acutely carinate 

 laterally. Abdomen petiolate and strongly compressed from the 

 second segment; basal segment narrow, with its apex strongly 

 dilated and the spiracles beyond its centre. Legs normal ; tarsal 

 cla\vs basally pectinate ; femora stout and not dentate. Areolet 

 wanting, the submarginal nervure emitted before the recurrent ; 

 radial nervure not short and broad. 



Range. World-wide. 



The species of this distinct genus are known to prey upon 

 Zygaenid and Pyralid moths, and in the United States, Ashmead 

 has bred one from a species of Apatura ; they spin a blackish 

 cocoon within that of their host and closely adherent thereto (cf. 

 Bridgman, E. M. M. 1889, p. 185) ; but the Indian species appear 

 to construct pendulous cocoons, a habit hitherto unobserved in 

 this genus. Walker has described one species, which he doubt- 

 fully ascribes to this genus from Japan, under the name G.luteipes 

 i(Cistula Entom. i, 1874, p. 307); the type is no\v lost.
