General color fuscous-black, the pale pattern pale ochraceous-buff to naples 
and mustard yellow. Head fuscous-black excepting the mouth-parts, which 
are buff, the pal{)i naples yellow, the distal joint tipped with fuscous. Prono- 
tum with the disk of the general color, the broad lateral borders, the narrower 
caudal margin and a fine thread along the cephalic margin, pale ochraceous- 
buff, the caudal outline of the dark disk sharply contrasted, the others faintly 
blending. Tegmina of the general color, with the marginal field and a broad 
marginal edging to nearly the whole of the scapular field, dull naples yellow, and 
a strongly contrasted, but relatively narrow, dash along the greater part of the 
discoidal vein mustard yellow. \Yings strongly washed with fuscous. Alxlo- 
men with the dorsal surface buckthorn brown, broadly but indefinitely edged 
laterad and distad with weak fuscous; cerci mustard yellow; ventral surface 
of thorax and coxae, excepting an isabelline wash to the cephalic coxae, of the 
general color of the abdomen, colored similarly to the dorsum of the same sec- 
tion, but with the fuscous lateral marginal areas deeper in tone and more 
sharply defined, while distad the subgenital plate is of the paler color. Limbs 
naples yellow; tarsi with a distal spot of fuscous and small ones of the same 
color at the base of the second and fourth joints. 
Length of body, 6.9 mm.; length of pronotum, 1.8; greatest width of prono- 
tum, 2.5; length of tegmen, 8.8; greatest width of tegmen, 2.5. 
The type of this striking species is unique.

Brazil.] 
Tijuca. April 9 to 11, 1913. (Malcolm Burr.) One male. 
This topotypic specimen fully answers the poor description of 
Walker as far as the latter goes except that the ej^es are hardly 
“wide apart.” However, as the type was a female, and the 
present individual is of the opposite sex-, this is easily explained, 
as the difference in this respect is alwaj^s more marked in the 
females of the Blattidae. 
The only locality from which the specjes has been recorded is 
Tijuca.

and his supposed synon 5 ’inous scrohicuJata shows conclusively
