rounded projection mesad ; very brief portion of plate between bases of styles 

 minutely triangular!}- produced, unspecialized, fitting tightly between bases of styles. 

 Cephalic femora with ventro-cephalic margin supplied with a long row of short, 

 closely placed, microscopic piliform spines, terminated by a single elongate and 

 moderately slender spine. Other ventral femoral margins unarmed except distad, 

 but supplied with a few moderately elongate hairs, both margins of median and 

 caudal femora with a single elongate, moderately slender distal spine. Median and 

 caudal femora with an elongate, moderately slender, dorsal genicular spine. Caudal 

 metatarsus very much longer than combined length of succeeding joints, supplied

In the type the wing is 7.1 by 4.5; the appendicular field, 1.9 by 2 mm. 



Head with vertex pale ochraceous-tawny, to a broad, blackish chestnut brown 

 band between the eyes, face entirely buffy. Underparts and limbs ochraceous- 

 bufif, ventral surface of abdomen light buff. Pronotum with disk pale ochraceous- 

 tawny, remaining portions transparent, very weakly tinged with buckthorn brown. 

 Tegmina, including veins, transparent, weakly tinged with buckthorn brown, ex- 

 cept narrowly along costal margin, where they are very weakh' tinged with the same 

 color. Wings transparent, with an exceedingly faint yellowish-brown tinge; in 

 area of costal veins and distad in anterior and radial fields faintly tinged with ochra- 

 ceous-buff. Dorsal surface of abdomen light buff, cerci light ochraceous-buff. 



In the specimen from Porto Bello, intensification in coloration is shown. The. face 

 and abdomen is buckthorn brown, the disk of pronotum and \ertex light cinnamon 

 brown. 1"

Chorisoneura specilliger'" new species (Plate VI, figures 16 to 19.) 



The present insect has the vertex showing two white hands, very 

 similar to those foiuid in C. translucida (Saussure), hut the ad- 

 jacent and intervening areas are all pale brown; the tegmina are 

 broader, show distinctive features of venation and taper more 

 evenly and decidedly distad from their point of greatest width.
