242 NEW NORTH AMERICAN DECTICINAE 



each margin, the proximal three uniform in length, the distal three decreasing 

 in length; dorso-caudal margin with five spines, dorso-cephalic margin with 

 one or two spines. Median femora subequal to cephalic femora in length: 

 median tibiae with at least six pairs of ventral spines, which are hexacentroid 

 but shorter than those of cephahc tibiae; dorsal margins each with five to six 

 spines. Caudal femora about four-fifths as long as the body, slender, moder- 

 ately inflated proximad: caudal tibiae slightly longer than the femora, all 

 margins spined; distal spurs three-paired, the third from the dorsal surface 

 little more than one-half as long as the second, dorsal pair nearly as long as 

 second pair, external first and second spurs slightly shorter than their internal 

 equivalents: caudal tarsi with plantula short, rounded. 



Allotype. — 9; same locality as type. Septeinl)er 2, 1918. 

 (J. A. Kusche.) [Hebard Collection.] 



The features here given are those of difTerence from the description of 



type (cf)- 



Size somewhat larger than in male sex. Pronotum as in male, l)ut eleva- 

 tion of caudal section less decided. Tegmina somewhat longer than the 

 greatest dorsal length of pronotum, ovoid-elliptical in outline, broadly 

 overlapping over dorsal surface of abdomen; greatest width of tegmina (flat- 

 tened) contained about one and one-half times in greatest length of same, 

 point of greatest width slightly proximad of middle: costal margin weakly 

 arcuate mesad, more decidedly arcuate proximad and distad, the apex nar- 

 rowly rounded rectangulate; sutural margin l>roadly arcuate: venation of all 

 but the axillary field much as in male but the veins weaker, axillary field 

 with three irregular oblique veins, which are connected by numerous cross- 

 veins, the areolets thus formed very similar to those of the marginal and dis- 

 coidal fields. Wings of the same structure and proportions as in the male, 

 and therefore actually smaller when compared with the pronotum. 



Abdomen with disto-dorsal tergite divided much as in the male, but the 

 fissation extends far deeper and embraces the whole visible portion of the 

 segment, the lateral angles of fissation not produced but rounded. Cerci 

 relatively short, inflated and incrassate in proximal half, thence tapering 

 rather sharply to the very slender distal section; surface papillose, with erect 

 hairs. Ovipositor subequal to the body in length, robust proximad, becom- 

 ing slender at proximal third, the margins of distal two-thirds parallel, entire, 

 the whole weakly but appreciably decurved, apex very acute, the dorsal 

 margin oblique truncate before apex. Subgenital plate short, subinflated, 

 lateral halves subquadrate in lateral view, the lateral angles rounded rect- 

 angulate: median line of the plate with an elevated lamellate carina in prox- 

 imal half, which mesad gives way to an impressed area with two obscure 

 indented lines, which embrace the end of the carina; distal margin mesad 

 with the distal margins of the lateral halves forming a U-shaped cmargina- 

 tion when viewed from the venter, this having a very small, but similar, 

 emargination at its very base. Seventh sternite with a median subcom- 

 pre.s.scd, trigonal projection, which is more vertical caudad than cephalad.
