distacl toward the dividing vein; axillarj- vein biraniose, one ramus diverging 

 mesad, the other distad; medio-discoidal area divided into ten rectangulate 

 areas of varying size by cross nervures; medio-ulnar area with several divisions 

 of similar character distad. Abdomen broad, depressed: supra-anal plate 

 trigonal, arcuate-emarginate laterad, narrowly bilobate with a deep narrow 

 sinus mesad, with long setae in the distal region; cerci elongate fusiform, 

 depressed, with scattered elongate setae; subgenital piate broad, margin 

 arcuate, weakly emarginate mesad. Femora without spines beneath except a 

 strong distal spine on each margin except the cephalic ventro-caudal; cephalic 

 femora with ventro-cephalic margin having a close series of short pile: dorsal 

 genicular spine absent from cephalic femora, present on median and caudal 

 femora: caudal tarsi with metatarsus faintly longer than the remainder of the 

 tarsus: arolia large. 



General color dull ochraceous-orange with the lateral portions of the pro- 

 notum and the marginal field of the tegmina clear hyaline, the ochi-aceous- 

 orange of the tegmina paling distad. Eyes fuscous. Dorsal surface of the 

 abdomen of the general color, darkening distad, ventral surface of the abdomen 

 ochraceous-tawny, the segments laterad and distad narrowly margined with 

 white. Limbs becoming ochraceous-buff distad. 



Length of body, 6.4 mm.; length of pronotum, 2.2; greatest width of prono- 

 tum, 2.6; length of tegmen, 6.8; greatest width of tegmen, 2.3. 



A badly damaged female individual from Manaos, Brazil 

 (collected by Miss H. B. Merrill), in the collection of the United 

 States National Museum, we have provisionally referred to this 

 species. The Manaos specimen has lost all of the limbs and the 

 apex of the abdomen is not perfect. If, as appears evident, this 

 individual and the tj'-pe are identical, the species has a consider- 

 able distribution. 



Chorisoneura pulcherritna new species (Plate XV, figs. 23, 24 and 25.) 



While apparently related to C. discoidalis Burmeister, the 

 pattern of this species is so distinctive it needs comparison with 

 none of the other forms of the genus. 



Type.— c^; Para, State of Para, Brazil. (C. F. Baker.) 

 [Acad. Nat. Sci. Phila., Type no. 5260.] 



Size rather small: form depressed: surface glabrous. Head with the occiput 

 largely exposed cephalad of the pronotum, broad, nearly straight in outline, the 

 least interspace between the eyes equal to one and one-half times the greatest 

 depth of the eye and but faintly less than the interspace between the antennal 

 scrobes: face gently rounded: ej^es when viewed from the cephalic aspect are 

 seen to have the margins distinctly converging to the position of the interocular 

 color band, then strongly sinuate about the antennal bases: antennae surpass- 

 ing the body in length, pro.\imal joint robust, slight!}' ciu'ved; second joint not 

 quite one-half as long as the proximal one; third joint slender, slightly more 

 than one-half as long as the proximal joint; remaining joints moniliform, very
