intercalary area rather small but distinct, extending about a sixth the 

 way to the base of the wing, the apical margin of the area ver}^ gently 

 obtuse-angulate. Supra-anal plate transverse, somewhat produced 

 mesad and very narrowly emarginate; cerci about equal to the sub- 

 genital plate in length, tapering in the distal half; subgenital plate 

 somewhat transverse, the distal margin arcuate, not emarginate and 

 not distinctly excavated for the cereal bases. Cephalic femora armed 

 on the ventro-cephalic margin, with about five large spines placed 

 mesad and a number of slightly smaller ones distributed between the 

 larger spines and the distal extremity; median and cephalic femora 

 with the ventral margins armed. 



General color vandyke brown, narrow lateral areas on the pronotum 

 and the basal areas of the tegmina ochre yellow. Head uniform except 

 for the antenna, the regions of their insertion and the clypeiis which 

 are dull ochraceous. Pronotum with the median area very dark, 

 almost seal brown, the lateral light areas being connected by a thread 

 of the same color, which extends around the cephalic margin. Teg- 

 mina almost ochraceous-rufous when viewed by reflected light, the 

 area of the right tegmen covered by the left being vandyke brown. 

 Wings washed with vandyke brown, the anterior field with the suf- 

 fusion very strong, the color being quite solid around the costal veins 

 Abdomen with the segments margined with seal brown, a broad bar 

 of the same color paralleling the lateral margins and suffusing the 

 subgenital of the preceding plate. Limbs ochraceous, the coxae each 

 with two transverse bars of seal brown connected along the lateral 

 sulcus of the coxa by a longitudinal bar of the same color.

BLATTELLA CaudeU. 

 Blattella minor (Brunner). 



1865. Ph[yllodromia] minor Brunner, Nouv. Syst. Blatt., p. 94. [Brazil.] 

 One male. 



This specimen fits Brunner's description of this species, except that 

 the bars on the pronotum are fairly well separated, while Brunner says 

 ' ' linea separanti tenuissima. ' '
