femora with distinct dorsal genicular spines: caudal tarsi with metatarsus 

 slightly more than one-half of the total tarsal length; arolia present. 



General color of head, thorax, abdomen and tegmina burnt sienna to chest- 

 nut; pronotum with disk dark seal brown. Head with a transverse bar between 

 the most approximate portions of the eyes cream color, this having a fine median 

 penciling of dark seal brown; eyes prout's brown; antennae and palpi buff- 

 yellow. Pronotum with the disk solidly colored, the caudal margin pale 

 ochraceous-buff, narrowing mesad, lateral margins broadly and cephalic 

 margin narrowly hyaline, tinted with light buff. Tegmina with marginal field 

 and almost all of distal two-thirds of scapular field, and a narrow costal margin- 

 ing connecting these two, subhyaline tinted with buffy, an obUque, faintly 

 arcuate bar, directed disto-caudad and placed at the apex of the anal field and 

 broadly connecting with the costal edging, of similar character. Wings 

 strongly washed with fuscous, the region of the costal veins for a considerable 

 section of the distal half opaque light orange-yellow. Thoracic segments and 

 dorsal apex of the abdomen washed with seal brown. Limbs buff-yellow. 



Length of body, 6.S mm.; length of pronotum, 1.7; greatest width of prono- 

 tum, 2.7; length of tegmen, 6.8; greatest width of tegmen, 2.2. 



The type of this beautiful and striking species is unique. 

 Chorisoneura personata new species (Plate XV, fig. 31.) 



Apparently close to C. inquinata Saussure and fordida Brunner, 

 differing from the former in the much smaller size, in the colora- 

 tion of the front and vertex and in the absence of any trace of a 

 humeral tegminal band. From sordida the present species differs 

 in the fewer rami to the discoidal vein of the tegmina and the 

 more fulvous coloration. 



Type. — 9 ; Independencia, State of Parahyba, Brazil. (Stan- 

 ford Expedition; Mann and Heath.) [Acad. Nat. Sci. Phila., 

 Type no. 5262.] 



Size small: form depressed, elongate ovate. Head but faintly projecting 

 cephalad of the cephalic margin of the pronotum, broad, depressed: occiput 

 gently arcuate when seen from the dorsum, the least interspace between the 

 ej'es equal to one and a half times their depth: antennae at least as long as the 

 body, proximal joint slightly enlarged: palpi with the third joint moderately 

 elongate, straight; fourth joint shorter than the third joint, slightly and 

 regularly enlarging distad; fifth joint subequal in length to the third joint, rather 

 slender, subequal proximad, tapering from the proximal two-fifths. Pronotum 

 moderately transverse, subreniform-ovate, its greatest length contained one 

 and a half times in its greatest width: cephalic margin relatively narrow, gently 

 arcuate; latero-cephalic angles very faintly indicated, regularly and broadly 

 rounded; lateral margins diverging oblique arcuate; latero-caudal angles 

 broadly rounded; caudal margin arcuato-truncate; greatest width slightly 

 caudad of the middle: disk arcuate dorsad when seen in section; hj^aline lateral 

 sections moderately declivent. Tegmina elongate lanceolate, very faintly 

 surpassing the apex of thesubgenital plate: costal and sutural margins regularly
