situated a heavy style (dextral), bent strongly sinistrad from its base, about 
twice as long as the short, straight i)ortion of its sinistral margin, tapering 
slightly to its rounded apex which is armed dorsad with minute teeth, im- 
mediately beyond the point o])posite the apex of this style on the margin 
a (sinistral) style of half the bulk siulngs erect, straight, with more sharjily 
rounded ajiex similarly armed; a bilef distance dextrad of the heavier style 
springs another process, with base slightly thicker than its cylindrical shaft, 
nearly eight times as long as its median width or three times as long as the 
smaller style, erect, nearly straight, cuiving weakly caudad, with rounded 
apex armed dorsad with minute teethd* 
Limbs and armament of same as characteristic of the genus. 
Head dark chestnut brown, ocelli light buff. Antennae, including first 
joint, mummy brown. IMouthparts, maxillary palpi, limbs and ventral 
surface of abdomen ochraceous-buff, the latter strongly tinged with cinnamon 
brown. Pronotum with disk heavily suffu.sed with cinnamon brown in a 
vague jjattern; latt'ral ])ortions ochraceou.s-buff, this narrowly invading the 
disk cephalad of the latero-caudal sulci; caudal portions transparent. Teg- 
mina translucent, dresden brown, the marginal field j)aler. Wings trans- 
parent, area between costal veins dark chestnut brown, shading to cinnamon 
brown toward the free margin and in the entire distal jrortion beyond the 
humeral vein, colorless between the dark chestnut brown princii)al veins. 
Dorsal surface ol abdomen buckthorn brown, suffused laterad with prout’s 
brown. Cerci j)rout’s brown. 
Length of body, 14.2; length of pronotum, 3.3; width of i^ronotum, 4.6; 
length of tegmen, 14.8; width of tegnien, 4 mm. 
The type is iinitpie. 
Ischnoptera implicata new species (Plate VIII, figure 11.) 
The present species is extreinely close to the Peruvian [.anguslr 
frons Hebard, Iteing: readily distingnishaltle only by the different 
development of the male g;enitalia within the anal chamber. In 
other respects, when compared with the male type of atnjustifrons, 
the unique male of implicata is seen to differ only in the consider 
ably more slender form, very slightly wider interocular space, 
less ample pronotum showing the latero-caudal sulci of the disk 
moi'e decided, suiti’a-anal plate with more extensive subchitinous 
area, and minor differences of coloration.

not noted in any other species (rf Isctnioptera, though the subgenital jilate of
