368 STUDIES IN THE ISCHNOPTERITES (oRTHOPTERA) 



Allotype. — 9 ; same data as type. [Am. Mus. Nat. Hist.] 

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

 in the following features. Size very slightly larger, form appreciably broader. 

 Interocular width very slightly less than that between the less distinct ocelli. 

 Dorsal surface of abdomen unspecialized. Supra-anal plate much as in 

 capitata. Subgenital plate much as in that species, but with emargination at 

 bases of cerei more decided and without a mesal emargination."

Coloration. — Head light buff to ochraceous buff, rarely washed 

 with ochraceous tawny between the eyes. Limbs and under- 

 parts of same general coloration, the ventral surface of the abdo- 

 men occasionally ochraceous tawny, the segments and coxae 

 with lateral dots of sepia as in capitata, these sometimes repre- 

 sented by large spots on the abdominal segments, while one 

 female has a dark brown spot mesad on the subgenital plate. 

 Pronotum ochraceous buff to ochraceous tawny, usually dis- 

 tinctly paler and buffy laterad. Tegmina translucent, pale 

 buckthorn brown. Dorsal surface of abdomen suffused to vary- 

 ing degrees with dark brown, narrowly margined laterad with 

 buffy, supra-anal plate blackish brown proximad with produced 

 mesal portion buffy. 



Specimens Examined: 17; 3 males, 6 females^^ and 8 immature individuals. 



Saona, Hayti, VII and VIII, (N. L. Orme Jr.), 1 9, [A. M. N. H.]. 



^1 One paratype shows a very slight emargination at this point; the female 

 subgenital plate can hardly be said to afford differential features between this 

 and the closely allied species of this group. 



62 As we have no males from Hayti, Porto Rico proper and the Danish West 

 Indies, there is a possibility that other species are included. These specimens 

 agree so closely with unquestioned females of flagellata, however, that we 

 believe additional material will substantiate their proper assignment here.
