The width of the caudal femur in the series is: d\ 3 to 3. 4; 9 , 3. 4. 4-4. 1 mm. 



Coloration very similar in the series, except that in the males the average 

 is slightly more contrasting and brilliant. Occiput, disk of pronotum and 

 dorsal surface of mesonotum and metanotum dull sayal brown (individually 

 varying from cinnamon to warm sepia in the specimens of maximum recessive 

 and intensive coloration). Cephalic and median limbs of this coloration, 

 showing vague irregularities of shade. Dorsal surface of male abdomen, in 

 proximal half shining blackish brown laterad, with a narrow medio-longi- 

 tudinal band of pinkish cinnamon, remaining portions sayal brown; in females 

 much more uniform, less shining, with latero-proximal portions only slightly 

 darkened and medio-longitudinal band very weakly defined, in some individ- 

 uals unicolorous. Remaining portions of head, lateral lobes of pronotum 

 and underparts clay color, except for a weakly defined postocular bar on each 

 side of the head (heavy in occasional specimens), which is continued on the 

 dorsal portion of the pronotal lateral lobes as a broad, solidly colored, shining 

 black band, in females often weak cephalad and caudad. On the sides, the 

 meta-episternum and the meta-epimerum are shining black. Tegmina 

 cinnamon-buff to clay-color in dorsal half, blackish brown to black and usually 

 shining in ventral half. Caudal femora of the general coloration dorsad, 

 paling to the ventral coloration ventrad, the external pagina vaguely and not 

 solidly suffused with a darker shade, which in some females shows a faintly 

 greenish tinge. Caudal tibiae varying from grenadine to peach red. 



This type of caudal femoral coloration is strikingly different from the normal 

 for huachucana, but a single male is before us agreeing fully in this respect with 

 that species. In that individual the external pagina is strikingly bicolored, 

 the dorsal portion almost black, the ventral portion ochraceous-buff. 



We would note that the usual difference from huachucana in the caudal 

 femoral coloration is also shown in the immature stages, when dark markings
