Head about as long as broad between eyes, the lateral 

 lobes considerably divergently spinously produced in front 

 of the apex of the central lobe, the lateral lobes are also 

 longly louiritudinally produced from near their ba'<e to the 

 base of the first joint of the antcnnse ; ocelli near eves ; 

 antenniferous tubercks prominently spinous externally ; 

 antenna four-jointed, first joint stoutest, sparingly strongly 

 hirsute, longly produced in front of head, second joint about 

 twice as long as first, third and fourth subequal, each much 

 shorter than second ; pronotum about half as long as breadth 

 between the lateral angles, the lateral margins strongly 

 sinuate and in front of the posterior angles dentate, the 

 angles shoitly obtusely spinously subprominent, basal margin 

 truncate in front of scutellum, anterior margin slightly con- 

 cave; scutellum much longer than broad at base, the apical 

 area attenuated, a small l)lack foveatc spot at each basal 

 angle ; corium about as long as [)ronotum and scutellum 

 together, the lateral margins a little rounded, the apical 

 margins oblique ; membrane passing the abdominal apex, 

 the veins longitudinal ; rostrum passing the anterior coxie, 

 first joint about or almost reaching base of head, second and 

 third joints subequal in length ; abdominal segments 1-5 

 ■with a transverse strigose \itta behind the spiracles; legs 

 moderately long, posterior legs longest, posterior femora 

 sulcate beneath and with two short spines near apex ; tarsi 

 triarticulate. 



This genus appertains to the group of genera distinguished 

 as Platycoraiia, liergr. (a name since altered by Kirkahly to
