366 STUDIES IN THE ISCHNOPTERITES (oRTHOPTERA) 



is situated a gently curved, chitinous, flagellate process, which is slightly 

 longer than the mesal production, the sinistral portion of the free margin ia 

 weakly oblique and straight to this flagellate process. Limbs and armament 

 of same as given in generic description. 



Allotype. — 9 ; same data as type. [Hebard Cln.] 



Description of Allotype. — Similar to male in ambisexual characters, differing 

 in the following features. Size larger, form a little broader. Interocular 

 width very shghtly less than that between the less distinct ocelli. Dorsal 

 surface of abdomen not specialized. Supra-anal plate much as in capitata. 

 Subgenital plate much as in that species, but with emargination at bases of 

 cerci more decided and with scarcely any mesal emargination indicated.^*

The series is not sufficiently large to determine the degree of 

 variability which occurs. 



Coloration. — Head, underparts and limbs light buff to ochra- 

 ceous buff; head with interocular area often more suffused with 

 tawny; dots on coxae and ventral abdominal segments as in 

 capitata, but normally very minute. Pronotum antimony yel- 

 low to ochraceous tawny, very slightly paler laterad. Tegmina 

 translucent, warm buff to weak ochraceous tawny. Dorsal sur- 

 face of abdomen much as in capitata, darker markings usually 

 not strongly defined. 



A single immature example before us has the head ochraceous 

 tawny, limbs buckthorn brown, ventral surface of abdomen 

 blackish chestnut. Pronotum, mesonotum and metanotum 

 mars brown becoming darker laterad, there narrowly bordered 

 with ochraceous buff. Dorsal surface of abdomen blackish chest- 

 nut, very narrowly bordered laterad with ochraceous buff. 



^* Were two of the species of the Capitata Group present in the same locality, 

 it would be a difficult task to separate the females, except in capitata and bicolor. 

 In the former a different, though slight, general facics from the others is usual, 

 in the latter this is more decided and constant.
