Vertex sanguineous, a large pale greyish spot near middle 

 of each lateral margin and a much larger and more ochra- 

 ceous-grey spot at base ; pronotum obscure ochi-aceous, a 

 central longitudinal carinate line and a broad sublateral 

 fascia on each side sanguineous ; scutellum sanguineous 

 (imperfectly seen in type) ; abdomen above, body beneath, 

 and legs pale ochraceous ; face and clypeus sanguineous, the 

 pale lateral spot on each side of vertex above continued and 

 distinct on each side of face ; vertex about as long as breadtli 

 betvreen eyes, moderately narrowed to apex, which is rounded, 

 ocelli near eyes ; pronotum a little longer than vertex, rugu- 

 lose, and in places coarsely granulose, a distinct transverse 

 impression before anterior mar2;in, strongly sinuate before 

 scutellum ; face broadly longitudinally flattened and de- 

 pressed_, roundly foveate at centre of base, the lateral areas 

 transversely striate ; tegmina greyish, with a pale flavescent 

 tint, with a central, longitudinal, much waved, brownish line, 

 very finely wrinkled and punctate, posterior claval and teg- 

 minal margins narrowly brownish ; wings greyish, subhyaline.

Type, P. marmorafa, Fabr, 



The type given by St.-Farg. & Serv. for Proconia was 

 P. cristata, Fabr. ; tliat given by Laporte for Germaria was 

 G. cucuUata. As will be seen by the following synonymy, 

 both these species are synonyms of C. marmorata, Fabr., 

 and the two genera must also therefore be synonymous. 

 Kirkaldy^s proposed new name constitutes another synonym.
