irregular, interspaces of distal section irregular in size and shape; texture cori- 

 aceous. Wings subhyaline, reaching to the tegminal apices, rather narrow. 

 Prosternal process a broad, low swelling bearing on its apex a short, sharp, 

 cephalad recurved tooth: interspace between the mesosternal lobes subquad- 

 rate, in width slightly less than one of the lobes, internal margins of lobes 

 subparallel, appreciably arcuate, caudal angles well rounded: mesosternal 

 lobes narrowly separated caudad. Supra-anal plate elongate, sublanceolate, 

 in transverse section arcuate, lateral margins gently arcuate, convergent to 

 the narrowly rounded apex, proximal half of the plate with distinct lateral 

 inter-marginal low carinae, a distinct medio-longitudinal, elongate-elliptical 

 sulciform impression and a faint transverse division separating the proximal 

 from the distal section of the plate: ovipositor valves elongate, considerably 

 compressed, the tips of both sets of valves strongly hooked, the external 

 margins of the dorsal valves crenulato-dentate. Cephalic and median limbs 

 quite slender. Caudal femora of average build, not markedly slender, sub- 

 compressed, in length equal to two-thirds that of the tegmina, greatest depth 

 contained three and one-third times in its greatest length; dorsal carina very 

 faintly serrulate, regularly supplied with long hairs, dorso-external and ventro- 

 external carinae simple, pattern of the paginae regular, open, dorso-genicular 

 margin with a faint median tooth; genicular lobes with their apices faintly 

 acute, ventral margin of the lobes sigmoid, deepest proximad: caudal tibiae 

 slightly shorter than the femora, faintly sigmoid in outline, slender, armed 

 on the external margin with six spines, on the internal margin with nine 

 spines: caudal tarsi with the proximal joint about twice as long as the second 

 joint; third joint subequal to the first and second joint together. 



General color (specimen dried from liquid preservative) olive-yellow, a pair 

 of broad lateral bars of fuscous black extending from caudad of the eyes, over 

 dorsal two-thirds of the lateral lobes of the pronotum, dorsal section of the 

 pleura, metanotum, dorsum of the thi-ee proximal abdominal segments and 

 over the tegmina, becoming fuscous on the latter. Head with the dorsal 

 section of the antennal grooves, occiput, vertex and on the fastigium weakly 

 fuscous black, regular disposed series of dots of the general color in diverging 

 lines extending from the fastigium around the eyes, a line of callose areas mar- 

 gining the eyes ventro-cephalad and the postocular bar ventrad, these strik- 

 ingly cream-buff; eyes mars brown clouded with fuscous; antennae of the 

 general color. Pronotum with the median and the position of the lateral 

 carinae distinctly of the general color, the base tone of the dorsum more ecru- 

 olive, the pale lateral dorsal lines contrasted mesad by a wash of fuscous; 

 lateral lobes with the greater portion of the pale ventral section callose and 

 cream-buff in color. Pleura with the callose cream-buff hue represented by 

 two oblitiue dashes, one dorso-cephalad of the insertion of each limb. Teg- 

 mina with the region of the anal vein narrowly marked with the general color. 

 Wings washed with fuscous, longitudinal veins strongly lined with fuscous- 

 black, transverse veins paler. Caudal femora with the genicular region and 

 proximal extremity of the tibiae washed with ferruginous, the genicular lobes 

 with several fuscous spots, tibial spines black tipped. 



Length of body, 15 mm.; length of pronotum, 3; greatest (caudal) width of 

 pronotal disk, 2.7; length of tegmen, 13.4; length of caudal femur, 8.7.
