198 BRAZILIAN DERMAPTERA AND ORTHOPTERA 



margin of interspace arcuate. Ovipositor valves moderately compressed. 

 Median femora with the ventral margin sublamellate and sinuate, the distal 

 extremity of the femur much heavier than the proximal portion, cephalic 

 and dorsal faces subcarinate. Caudal femora but slightly shorter than the 

 tegmina, moderately compressed, dorsal margin with distinct serrate projec- 

 tions inclined distad; dorso-external carina with a similar median projection 

 and proximad and distad other smaller but similar points, ventro-external 

 carina with a median pair of serrate projections; external pagina with a close, 

 impressed, sub-imbricate pattern of chevron-shaped figures; dorso-median and 

 lateral genicular lobes produced, narrow: caudal tibiae robust, armed on the 

 external margin with nine spines; caudal metatarsus slightly longer than the 

 second and third tarsal joints together. 



General color verona brown, paling to sayal brown on the pronotum, with 

 certain pale areas on the lateral lobes of the pronotum and caudal femora, clay 

 color. Eyes buckthorn brown, antennae of the general color. Pronotum with 

 scattered lines of blackish on certain of the points; lateral lobes of pronotum 

 with an irregularly indicated pale area ventro-caudad. Tegmina weakly 

 lineate with bone brown along the principal veins and marmorate with the 

 same in the median area of the tegmina, as commonly found in the genus, also 

 distinctly painted with the same color on the rami of the disto-sutural section. 

 Wings washed with blackish. Al:)domen mars brown. Limbs of the general 

 color; caudal femora with three transverse pale areas, irregularly outlined, 

 but subchevron-shaped on the external face, the distal pale area distinctly 

 indicated on internal face alone. 



Length of bodj', 30 mm. ; length of pronotum, 9.2; greatest width of pronotal 

 disk, 9.3; length of tegmen, 16. S; greatest width of tegmen, 5.2; length of 

 caudal femur, 15.4. 



The type of this striking species is unique. 



Parossa ampla new species (Plate X, figs. 8 and 9.) 



AlUed to P. bimaculata (Giglio-Tos), but differing in the blunter 

 caudal angle of the pronotal disk, in the broader tegmina (see 

 plate X., figs. 9 and 10) which are subequal in width to the great- 

 est dorsal pronotal width, in the apical region of the tegmina 

 being much less acute and rounded at the extreme apex instead 

 of acuminate as in bimaculata, and in the shorter and blunter 

 ovipositor jaws. 



Type. — 9 ; Franga, State of Sao Paulo, Brazil. January, 

 1911. (E. Garbe.) [Acad. Nat. Sciences Phila., Type no. 5279.] 



Size medium : form as usual in the genus : surface of the peculiar texture and 

 with the usual vestiture found in the related P. himaculata. Head as in P. 

 bimaculata. Pronotum identical with that of P. bimaculata but with the caudal 

 margin of the pronotal disk very Ijroadly obtuse-angulate and hardly produced. 

 Tegmina relatively broad, in greatest width subequal to the greatest caudal 

 width of the pronotal disk; in length the tegmina surpass the apices of the
