the adjacent portions. Lateral margins of cheeks weakly conver- 

 gent ventrad. Maxillary palpi moderately short for the genus, 

 fourth joint nearly as long as third, large fifth joint three-quarters 

 as long as fourth. Tegmina decidedly reduced, covering slightly 

 less than half the dorsal surface of the abdomen; costal margin very 

 gently arcuate, broadly rounding distad into the broadly rounded 

 distal margin, sutural margin nearly straight, rounding much more 

 suddenly, though broadly, into the distal margin; venation dis- 

 tinct, the caudal margin cutting the veins abruptly, the discoidal 

 sectors (3 to 6 in the series) cut off before reaching a truly longitudi- 

 nal direction, so that the portions shown appear very weakly oblique 

 to the sutural margim\ Wings vestigal, extending to the caudad 

 margin of the metanotum. Supra-anal plate two-fifths as long as its 

 basal width, lateral margins broadly concave-convergent to dis- 

 tal portion, which is bilobate, due to a moderate meso-distal emar- 

 gination (which is sharp in the type, rounded in the paratype). 

 Subgenital plate simple, large, weakly produced, the free margin 

 weakly concave beneath the cerci and mesad, weakly convex be- 

 tween these portions. Ventro-cephalic margin of cephalic femora 

 armed with (4 to 6; in the case of the greater number, with the last 

 two considerably smaller) heavy, elongate, well-spaced proximal 

 spines, succeeded by a row of (11 to 15) minute, closely placede 

 chaetiform spinulae, terminated by three heavy spines, elongats 

 in increasing ratio distad. Pul villi of four proximal tarsal joint, 

 unusually large for the genus, occupying the entire ventral surfaces 

 of the three tarsal joints succeeding the metatarsus, apices acute, 

 Tarsal claws symmetrical, well-developed flanges with (5) teeth 

 decided. Moderately well-developed arolia present. 



Head with vertex light ochraceous-tawny with an orange tinge, 

 a large transverse suffusion of chestnut-brown between the ventral 

 portions of the eyes and dorsal portions of the antennal sockets, 

 ocellar spots and face ochraceous-buff, the latter with a narrow, 

 transverse suffusion of chestnut-brown above the clypeus, which 

 broadens on the cheeks. In one paratype there is an additional 

 narrower transverse suffusion of the same color between these. 

 Pronotum in median portion light ochraceous-tawny with an orange 

 tinge, this bordered on each side by a longitudinal suffusion of 

 chestnut-brown, which broadens caudad; disk with light flecks of 

 chestnut brown,'*'' three in an oblique row on each side mesad, two 

 caudad ; lateral portions transparent, faintly tinged with buffy, mar- 

 gins themselves buffy with an orange tinge. Tegmina showing a 

 continuation of the pronotum coloring, the suffusion of the humeral 



*" This is not true of puerilis, in which the tegminal reduction is as great, but 

 the brief portions of the discoidal sectors are plainly longitudinal to the sutural 

 margin. It would appear that reduction of these organs affects the direction of 

 the veins more in some species than in others. 



^^ In one paratype of more intensive coloration these flecks are supplemented 

 by small, weak suffusions and lines, giving a more nearly pictured appearance.
