eyes, the infuscate pronotum and longitudinal fuscous lining of 

 the caudal femora. 



Type. — 9 ; Franga, State of Sao Paulo, Brazil. January ,, 

 1911. (E. Garbe.) [Acad. Nat. Sci. Phila., Type no. 5337.] 



Size rather large: form slender (for the genus), subcompressed : surface 

 covered with adpressed golden pile. Head ^\Tth its caudal width subequal to 

 the cephalic width of the pronotum, greatest depth of the head nearly one 

 and one-half times the greatest width of the head across eyes: occiput rather 

 strongly inflated and rounded, strongly arcuate declivent to the interocular 

 region, which is hardW produced or angulate when seen from the side, in width 

 slightly less than that of the proximal antennal joint; median ocellus poorly 

 indicated; facial section of the rostrum weakly compressed: eyes but little 

 prominent, rather small, broad ovoid in basal outline, their depth but slightly 

 greater than that of the infra-ocular portion of thegenae: palpi elongate, slender, 

 the third and fourth joints su])equal in length, the fourth more slender, par- 

 ticularly proximad, than the third joint; fifth joint subequal in length to the 

 fourth joint, infundibuliform, very broadly arcuate, the distal margin 

 strongly oblique, arcuate, the immediate apex blunted : antennae nearly three 

 times as long as the body; proximal segment inflated on the ventral surface. 

 Pronotum stronglj' arcuate dorsad in transverse section, broadly rounding 

 into the lateral lobes, greatest median length of the pronotum subequal to 

 the greatest caudal width: cephalic margin of disk strongly and regularly 

 arcuato-emarginate; caudal margin rather strongly arcuate; lateral borders 

 of disk faintly converging cephalad: lateral lobes of pronotum longitudinal, 

 the greatest depth caudad and this contained i\\\ce in the length of the lobes; 

 ventro-cephalic angle rather Ijroadly rounded; ventral margin straight, slightly 

 declivent; ventro-caudal angle broadly rounded rectangulate, the lobes mod- 

 erately impressed ventro-caudad: all margins of the pronotum cingulate, the 

 ventro-caudal section of the lobes broadly so. Tegmina reaching to the apex 

 of the abdomen: lateral field broad, its greatest width contained not quite 

 four times in the tegminal length, full, the costal margin arcuate; mediastine 

 vein with four rami, the field with three proximal free veins; humeral vein 

 simple, following the curve of the mediastine vein: dorsal field subequal in 

 width to the lateral field; median vein with three suVjlongitudinal rami distad, 

 the median origin of which is not sharply indicated; ulnar vein biramose; anal 

 vein simple; axUlarj' veins four in number, all the veins and rami of the dorsal 

 field parallel, but weakly oblique, cross-veins indicated, and then but weakly, 

 distad and mesad. Wings surpassing the closed tegmina by nearly three- 

 fifths the pronotal length. Ovipositor three-fourths the length of the caudal 

 femora, gently arcuate in lateral outline, depressed; distal valves faintly wider 

 than the main shaft of the ovipositor, the base of the dorsal valves indicated 

 by a very weak, transverse carina, the external margin being weakly toothed 

 at the marginal end of the carina, external margins of the dorsal valves regu- 

 larly arcuate-convergent from the middle to the acute apices of the valves, 

 the distal third of the surface of the valves transversely scored, this area 

 obliquely deUmited mesad and causing the external margin to be finely crenu- 

 late: ventral valves of approximately the same length and shape as the dorsal
