The measurements of all the specimens before us of the present 

 species are given above, these indicate that there is considerable 

 variation in the proportions of griseus, but in other respects the 

 specimens are very similar. 



Color Notes. — The specimens we have examined are quite similar 

 in coloration. General color, in pale specimens, hair brown; in 

 dark specimens, clove brown washed with grayish. Head below the 

 antennae deep shining piceous, above of the general coloration with 

 two or sometimes three usually distinct, dark, narrow, longitudinal 

 stripes on the occiput. Eyes wood brown. Maxillary palpi with

penultimate segment the palest, terminal segment very dark. Dor- 

 sum of pronotum, dorsal surface of abdomen and of caudal femora of 

 the general coloration, excepting that the first segments of the 

 abdomen, concealed beneath the tegmina, are shining black, while 

 the exposed segments have each a small dark median spot. Lateral 

 lobes of pronotum broadly banded with clove brown, the ventral 

 margin narrowly marked with buff, which marking is, in the majority 

 of specimens, a mere line. Tegmina translucent; male with dorsal 

 field of the general coloration, the discoidal vein narrowly outlined 

 in buff, lateral fields clove brown becoming pale toward the costal 

 margin; female with dorsal field broccoli brown, in some specimens 

 somewhat tinged with rufous, intermediate channel somewhat paler 

 with a black line on the dorsal margin bordering the median vein, 

 lateral field similar in coloration to the dorsal field with the exception 

 of a dark area between the humeral and mediastine veins, which in
