The pronotal type resembles more closely the normal in the 

 Group Ischnopterites than it does that found in the related genera 

 of the Group Blattellites. 



Material representing four species of the genus is before us.^^ 

 Genotype: Chromatonotus lamprus new species. 



Generic Description. — Size small, form slender, structure not as 

 delicate as is usual in the Group. Interocular space wide; vertex 

 rounding evenly into face; ocellar spots in the male sex decided, 

 with fiat surfaces oblique to intervening area as in Ischnoptera, 

 weakly developed in the female sex; face moderately convex, very 

 brief lateral margins strongly convergent to clypeal suture. Max- 

 illary palpi short, heavy distal joint as long as or longer than any 

 other, Pronotum feebly transverse ; surface convex, more so than is 

 usual in the Group Blattellites, much as in some of the smaller 

 species of Ischnoptera. Tegmina and wings fully developed in both 

 sexes. Tegmina narrow, discoidal sectors (seven or eight) longitud- 

 inal. Wings with anterior field narrow, resultantly short costal 

 veins thickened distad ; discoidal and unbranched median vein con- 

 nected by numerous transverse veinlets; ulnar vein with few (one 

 to (rarely) three) complete branches, showing bases only of. trans- 

 verse veinlets toward fold of the wing; intercalated triangle broad 

 and conspicuous; radiate field ample. Dorsal surface of male 

 abdomen unspecialized; paired plate beneath supra-anal plate 

 highly specialized; subgenital plate asymmetrical. 



Limbs rather heavy and short for the Group. Ventro-cephalic 

 margin of cephalic femora armed with a few well-spaced hea\y elon- 

 gate spines, succeeded by a row of minute chaetiform spines, termi- 

 nating in three heavy and very elongate distal spines in increasing
