200 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



situated a slender decurved tooth which is, however, broad at its base, this tooth 

 directed mesad and nearly perpendicular to the shaft of the cercus, the external 

 margin of which is weakly angulato-concave, beyond the proximo-mesal 

 swelling the cercus is greatly depressed and flattened particularly on the inner 

 side, this distal half strongly produced with sides very weakly converging to 

 the broadly rounded apex. Subgenital plate bearing disto-laterad very short 

 styles, distal margin of the plate very weakly convex, nearly transverse. 

 Cephalic and median limbs much as in brevipennis, caudal limbs decidedly 

 longer, caudal femora with ventro-external margins armed with a number of 

 small stout teeth (3 and 3), genicular lobes strongly bispinose. Coloration of 

 insect distinctive and striking. 



Allotype. — 9 ; data same as the type. 



Description of Allotype. — Similar to type, very shghtly larger. Tegmina 

 lanceolate with rather sharply rounded apex, half as long as abdomen; wings 

 sHghtly shorter. Ovipositor distinctly but not decidedly longer than caudal 

 femur, broad, approximately straight in du-ection but showing a very evident 

 open-sigmoid curve. Subgenital plate similar to that of hygrophilus. Colora- 

 tion distinctive and striking as in type.

■""' The material upon which these color notes are based was, when fresh, 

 kept in a 3% solution of formaldehyde for about ten hours. This treatment 

 has preserved the gi-een coloration almost in its entirety, but the other delicate 

 colors are not as brilliant as in life and the coral red spots of the caudal femora 

 have wholly disappeared. Still weaker solutions of formaldehyde, applied for 

 a longer time, may l)e found to hold these evanescent colors. At present our 

 exj)criinents are preliminary but have shown a definite im])rovement over sim- 

 ply drying the material.
