102 COLOMBIAN DERMAPTERA AND ORTHOPTERA 



Genera] coloration of male pale ochraceous-tawny, the lateral portions of 

 pronotum and tegmina transparent, tinged with ochraceous-buff. Head 

 ochraceous-buff with interocular area suffused with prout's brown, three pairs 

 of suffused flecks of this color (remnants of transverse bands) below on the face 

 and a fleck of this color below each antennal socket. Underparts and limbs 

 clear ochraceous-buff. 



Females similarly colored but with interocular area paler, in one scarcely 

 suffused, in the other weakly clouded with ochraceous-tawny; facial flecks as 

 pronounced as in male. This sex also has the tegmina more heavily suffused 

 with ochraceous-buff in median .section, beyond this hardly at all suffused and 

 ventral surface of the abdomen ochraceous-buff with a lateral marginal suffu- 

 sion of chestnut, becoming broader and deep shining chestnut-brown along the 

 free margin of the subgenital plate. 



In addition to the type and allotype, a single paratypic female, 

 bearing the same data, is at hand.

Ischnoptera apolinari new species (Plate XV^I, figs. 6 and 7.) 



The present species is widely distinct from any of the described 

 forms of the genus. With I. pallipes, pampaconas^^ and colomhiae,

The description of this insect is insufficient. The dried alcoholi'c type before 

 us shows differences from /. apolinari in the decidedly longer, uniform blackish 

 chestnut pronotum and less delicate wings with veins blackish chestnut. 



The genitalic features are distinctive. Supra-anal plate of same form as in 

 apolinari, but with disto-dorsal surface heavily supplied with hairs and ventral 

 surface unspecialized and not hairy. Subgenital plate with margins rather 

 strongly concave to the median produced jiortion, which is not large, subquad- 

 rate, with distal angles rounded, the disto-dextral angle very ))roadly rounded; 

 sinistral style situated at sinistral base of produ(!tion, small, simple, cylindrical, 

 feebly curved dextrad, tapering to the sharply rounded apex; dextral style 

 (Plate XVI, fig. 5a) situated at disto-dextral angle of production, proximal 

 portion developed into a large, globose, smooth swelling, from which dorso- 

 caudad projects caudad the rather stout, distal cylindrical portion, the 'apex
