198 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



Allotype. — cf" ; Milneburg, Orleans Parish, Louisiana. Juty 22, 

 1905. (A. P. Morse.) [Morse Collection.] 



Descripiion of Allolype. — Very similar to type, size slightly smaller. Tegmina 

 very similar to those of aigialus, delicate in structure, abbreviate, reaching to 

 base of penultimate dorsal abdominal segment, tympanum short and broad, 

 veins and veinlets very delicate; wings slightly shorter than tegmina. Distal 

 portion of abdomen, including cerci, raw sienna. Cerci elongate, mesal por- 

 tion ovate, bulbous and swollen with that portion above ventro-proximal tooth 

 produced in an overhanging knob-like protuberance, at the proximal base of 

 this swelling is situated interno-ventrad a slender decurved tooth, directed mesad 

 and nearly perpendicular to the shaft of the cercus, the external margin of which 

 is weakly concave, beyond the mesal sweUing the cercus is greatly depressed 

 and flattened, this distal portion strongly produced with sides very weakly 

 converging to the broadly rounded aiyex. Subgenital plate bearing disto- 

 laterad short styles, the distal margin of the plate is weakly convex.

Coloration. — General color pale green (bright green in life). 

 Eyes cinnamon brown. Dorsum of head and pronotum with a 

 weakly indicated band of pale brown. Tegmina and wings trans- 

 parent, warm buff. Distal half of male abdomen, including cerci, 

 raw sienna; in life prol^ably much more brilliant and approaching 

 orange more closely in shade. In the female the abdomen at the 

 base of the ovipositor is washed weakly with this color. Genic- 

 ular areas of caudal femora yellowish. 



The unique female of the present species before us is macro p- 

 terous, while the unique male is brachypterous. 



The ventro-external margins of the caudal femora are armed 

 with small but heavy spines; in the female 2-2, and in the male 

 3-4. 



The present species is only known from the localities given 

 below. 



Specimens Examined: 2; 1 male and 1 female.

 marsh), 1 9, type, (macropterous).
