Class I, HEXAPODA. 



Order XI, ORTHOPTERA. 



A NEW CYRTOXIPHA FROM THE UNITED STATES 



By a. N. Caudell, 

 Washington, D. C. 



The genus Cyrtoxipha is represented in the United States by two 

 small species hitherto reported only from the southern states. These 

 are gundlachi and delicatiila. The latter species I have taken in the 

 District of Columbia and Mr, Banks has taken it at Falls Church, Va. 

 Gundlachi is in the National Museum from Florida and from Cuba. 



A third United States species has just been discovered. It may 

 be known as C. columbiana and can be distinguished by the following 

 table : 



Table of United States Species of Cyrtoxipha. 

 A. Color yellowish green ; wings decidedly less than twice as long as the elytra. 



B. Smaller and more slender ; ovipositor of the female apically armed with acute 

 serrations; dorsal area of the female elytra with inconspicuous cross veins. 



gundlaclii Sauss. 



BB. Larger and stouter; ovipositor of the female armed apically with blunt 



tubercles ; dorsal area of the female elytra with more conspicuous 



cross-veins colutnbiana n. sp. 



AA. Color reddish brown ; wings twice or more than twice as long as the elytra. 



delicatula Scudd. 



Cyrtoxipha columbiana, new species. 



Color uniformly yellowish green except the ovipositor of the female and the eyes 

 of both sexes, which are black. The anterior tibia is moderately swollen at the tym- 

 panum, which is distinct on both faces. Antennas long and slender, unhanded, 

 darker apically. Pronotum almost twice as broad as long, broader posteriorly, and 

 above slightly flattened, the posterior margin a little rounded. Elytra ample, surpas- 

 sing slightly the tip of the abdomen, the cross-veins of the dorsal area of the female 

 more conspicuous than in our other species of the genus. Wings caudate, about one 

 half as long again as the elytra. Ovipositor curved upwards and apically armed above 

 with several minute tubercles, below nearly smooth ; at the extreme base the ovipos- 

 itor is reddish yellow but beyond that it is piceous. 



Measurements, $ and 9 : Length, of body to apex of the elytra, 8.5 mm.; 

 pronotum, 1. 5 mm. ; elytra, 6 mm.; wings, beyond the tip of the elytra, 3 mm.; 

 posterior femora, 5.5 mm.; ovipositor, 3.5 mm.
