184 BRAZILIAN DERMAPTERA AND ORTHOPTERA 



moderately robust, in length subequal to the third, second joint very short, 

 fourth joint rather short, thence distad the joints are moniliform, longitudinal, 

 regularly increasing in length; dorsal surface of the head with the usual sulci 

 subobsolete, caudal margin faintly emarginate mesad. Pronotum with great- 

 est length subequal to median width, cephalic margin truncate, cephalo-lateral 

 angles narrowly rounded, lateral margins straight and regularly diverging 

 caudad, caudo-lateral angles well rounded, caudal margin considerably arcuate, 

 lateral margins finely cingulate; a delicate medio-longitudinal line is finely 

 impressed cephalad and faintly elevated caudad. Tegmina slightly shorter 

 than the pronotum; strongly and continuously cingulo-carinate at the lateral 

 bend; sutural margins straight, attingent; distal margin obliquely arcuato- 

 truncate, the slope of the same directed laterad. No exposed wings. Abdo- 

 men faintly fusiform, the second and third dorsal segments with poorly defined 

 lateral folds; disto-dorsal segment transverse, its greatest width more than 

 twice its greatest length, lateral margins of same subparallel, distal margin 

 shallowly arcuato-emarginate at the base of each arm of the forceps, shallowly 

 arcuato-emarginate dorsad of the base of the pygidium, a distinct X-shaped 

 impressed area present me.sad and not quite touching the caudal margin; forceps 

 heavy, symmetrical, slightly shorter than the abdomen, proximal two-thirds 

 of the arms straight, distal third gently arcuate inward, the extreme apex 

 faintl}' hooked, the internal margin at five-eighths the length from the })ase with 

 .a short but distinct tooth, proximad of which there is a continuous though 

 narrow projection of the margin, moderately arcuate with several very fine 

 serrulations; process of the pygidium almost half as long as the abdomen, 

 linguiform, faintly narrowing from the base to the middle, then faintly expand- 

 ing again distad to the apex, which latter is obtuse-angulate emarginate; disto- 

 ventral segment transverse, free margin arcuate with a very shallow V emargi- 

 jiation mesad. Limbs rather short; femora moderately robust. 



Allotype. — 9 ; Same data as type. 



Differing from the description of the type chiefly in the features here given. 

 Disto-dorsal alidominal segment with distal margin truncate mesad and faintly 

 obhque truncate at base of forceps; forceps much lighter in build than those 

 of the male, little more than half as long as the abdomen, triquetrous in proxi- 

 mal section, regularly attenuate from base, nearly straight in basal half, gently 

 bending inwards in distal half with the extreme apex as in the male, the arms of 

 the forceps well crossed, internal margins of forceps sublamellate proximad with 

 several distinct serrations; pygidium tucked between the forceps; disto- 

 ventral abdominal segment with the free margin well arcuate with a faint 

 median angulation. 



General color blackish brown with a touch of maroon on the abdominal 

 segments, the translucent lateral margins of the pronotum showing up dark 

 honey yellow. Mouth parts clay color; antennae verona brown; limbs mikado 

 brown; forceps and pygidial process kaiser brown.
