226 BRAZILIAN ORTHOPTERA 



surpassing) the apices of the tegmina, greatest width contained faintly more 

 than one and one-half times in the greatest length: costal margin subtruncate 

 in distal half, apex well rounded: anterior field quite broad; intercalated tri- 

 angle small, elongate: discoidal vein straight, except for a slight arcuation 

 distad; costal veins fourteen in number, occasionally these are bifurcate, non- 

 clavate; median vein sinuate; medio-discoidal area slightly wider than the 

 medio-ulnar area, divided into a great number of rectangulate, generally trans- 

 versely oblong, areas by distinct transverse veins; medio-ulnar area divided 

 nto rectangular, generally cjuadrate, areas, less numerous than those of the 

 medio-discoidal area and with the cross-veins in large part incomplete ceph- 

 alad; ulnar vein with two complete rami reaching the apical margin and 

 five incomplete rami toward the dividing vein; axillary vein biramose mesad. 

 Sixth dorsal abdominal segment with its margin broadly V-emarginate mesad; 

 seventh dorsal abdominal segment depressed meso-cei)halad under the emar- 

 gination of the preceding segment, moderately vaulted and broadly U-emar- 

 ginate meso-caudad; eighth dorsal abdominal segment very short, bearing 

 mesad a rounded glandular area; ninth dorsal abdominal segment broadly 

 arcuato-emarginate. Supra-anal plate transverse, margin weakly and rather 

 broadly sinuate laterad, broadly arcuate and moderately produced mesad^ 

 margin strongly hirsute; when seen from the caudal extremity the ventral 

 surface of the plate is seen to have on the dextral side an elongate peg-like 

 process, which is directed ventro-mesad within the subgenital plate: cerci 

 depressed, subfusiform, acute distad, hirsute, i)articularly ventrad: subgenital 

 plate moderately uns3'mmetrical, styles median, small, slender, simple, 

 subequal in length and in approximately their usual position. Cephalic 

 femora with the ventro-cephalic margin bearing four large median and proxi- 

 mal spines, distad of which is a series of short, fine, regularly disposed and 

 subequal spinules, three apical spines on the same margin large. Median 

 and caudal femora with the ventral margins armed with regularly placed 

 spines: no dorsal genicular spines on the cephalic femora, distinct ones on 

 the median and caudal femora: caudal tarsi with the metatai'sus faintly 

 longer than the remaining tarsal joints; arolia small. 



Allotype. — 9 ; Same data as type. 



The features here given are those of difference from the description of the 

 male type given above. Interspace between the eyes broader than in the 

 male sex, but retaining its relative proportion to that between the ocelli; eyes 

 with their greatest depth but little greater than the interocular space. Abdo- 

 men with no scent-gland opening on dorsal surface. Supra-anal plate mod- 

 erately transverse, sinuate laterad, broadly V-emarginate mesad and the mar- 

 gin rounded laterad of the same : subgenital plate broad, the margin rounded. 



The differences between the recessive and intensive types of coloration is 

 very decided, although the pattern changes but little and the depth of the 

 tone is almost entirely responsible for the apparent diversity. General color 

 cinnamon-buff to clay color, the head, disk of the pronotum and the vicinity 

 of the proximal section of the mediastine vein infuscate with warm sepia to 

 blackish. Head dark; mouth-parts, palpi and ocelli warm buff to ochraceous- 

 tawny; antennae prout's brown to fuscous, proximal jo nt paler; eyes very 

 dark chestnut brown. Pronotum with the dark disk pattern reversed tri-
