veins and reticulations all very dark-brown, membrane of anal half 

 transparent with pink and green reflection, of humeral half rather 

 strongly infuscated. Length of tegmina 17 mm. 



Variations (13 specimens). — Many of the specimens are in general 

 much paler than the type^ and in the majority the stripes on the outer 

 sides of the posterior legs are much less distinct. The maculation of 

 the tegmina varies from brown to black. In nearly all cases the ante- 

 rior black spots meet each other mesially, and in many the median 

 spots also meet — in nearly all they approximate each other much more 

 than in the type, or are connected by a lateral spreading of a con- 

 densation of the dorsal spots of the intervening area of the tegmina. 

 Nine of the specimens have the slaty color of the gense well marked as 

 in the type, three of the others are everywhere very pale, while the 

 fourth is unusually dark. The ventral surface of the thorax is in all 

 the specimens pale, much paler than the lateral parts. The prozonal 

 markings are best developed in the type; in the others the thorax is 

 usually dull reddish-brown. In a few the small spots of the apical 

 part of each tegmen are so crowded as to form a third dusky area half 

 way between the median blotch and the tip of the wing.

var. nov. 



From Charles Island. 



Description of the Type. Male. — Head almost uniform and pale 

 without stripes, somewhat dusky above and on the front ; genae lacking 

 the slaty color. Pronotum pale yellowish-brown ; metazona dusky 

 along posterior margin ; no sign of stripes on the side of the prozona. 

 Sides of mesothorax and metathorax yellowish-brown ; sterna of the 

 same segments much paler than sides, being a pallid gray. Hind 

 femora pale brownish on outer side with no trace of black bands, a 

 few dusky spots along upper and lower carinae, floor of ventral groove 

 between the inner and median lower carinae black except posteriorly 

 where it is the color of the outer surface of the femur; inner surface 

 with a large black area occupying nearly the anterior half of the 

 femur, and a second smaller one occupying the position of the median 

 black blotch of the Albemarle specimens, both fused below with the
