30 THE BLATTIDAE OF PANAMA 



Coloration dark. Head with occiput, to just above ocelli, deep bay ; eyes blackish ; 

 ocelli buffy; face ochraceous-buff, shading through ochraceous-orange to ochraceous- 

 tawny mesad toward clypeus. Antennae and maxillary palpi prout's brown. Pro- 

 notum solid shining blackish brown, except narrow lateral margins which are trans- 

 parent, faintly tinged with buffy. Tegmina translucent, blackish brown, shading 

 to dresden brown distad and in area of dextral tegmen concealed when at rest; 

 marginal field transparent, faintly tinged with buffy. Wings hyaline, faintly tinged 

 with brown, except in area of costal veins and distal portion of anterior field, where 

 the suffusion is more decided, dresden brown, reaching the maximum in the area 

 of the enlarged costal veins, there translucent, deep prout's brown. Dorsal sur- 

 face of abdomen buffy, heavily tinged with blackish brown, this suffusion solid on 

 supra-anal plate and preceding segment. Cerci blackish brown, except meso- 

 dorsal area which is dresden brown. Ventral surface of insect suffused laterad with 

 blackish brown; remaining portions of coxae and the limbs translucent, buckthorn 

 brown, except dorsal margins of the femora, tibiae and tarsi, which are suffused 

 with blackish brown. Ventral surface of abdomen ochraceous-buff with an orange 

 tinge, suffused with ochraceous-tawny, except narrowly laterad, where brief but 

 decided suffusions of blackish brown occur on each segment. 



In addition to the type, a single paratypic male, bearing the 

 same data, but taken July 28 to August 5, 1916, is before us. This 

 specimen fully agrees with the type. 



Two small immature examples from Gatun, and one from Porto 

 Bello, are probably referable to the present species.
