364 STUDIES IN THE ISCHNOPTERITES (oRTHOPTERA) 



The very decided variation, in size and in length of tegmina 

 and wings, has evidently no geographic correlation. Though 

 the series is not sufficiently large to determine the full range of 

 variation, there appears to be sufficient material to show that 

 the normal size is approximately that of the nearly largest exam- 

 ples measured above; that the males normally have the tegmina 

 and wings extending beyond the apices of the cerci, while the 

 females are normally stouter with tegmina and wings extending 

 just beyond the apex of the abdomen. A single female has the 

 tegmina and wings decidedly reduced, falling short of the base 

 of the supra-anal plate, while two of this sex have these organs 

 as fully developed as in any of the males. 



Coloration. — Head warm buff to cinnamon buff, often suffused 

 with ochraceous orange, eyes sepia. Pronotum ochraceous 

 tawny to buff (rare), usually slightly paler laterad. Tegmina 

 translucent, tawny to ochraceous buff (rare). Wings hyaline 

 with a faint brownish tinge, veins brownish, the mesal area 

 of the costal veins at the margin buffy. Dorsal surface of 

 abdomen: (d^) suffused with brownish, with lateral margins 

 narrowly buffy; ( 9 ) suffused with blackish brown particularly 

 distad, the buffy margins in consequence much more conspicu- 

 ous, these continued on and often extending over the entire supra- 

 anal plate. General color of ventral surface and limbs warm 

 buff to cinnamon buff, rarely suffused with ochraceous salmon, 

 and with prouts brown laterad on the abdomen; lateral dots of 

 sepia are present at base of each coxa and laterad on the second 

 to sixth ventral abdominal segments.
