accompanied the specimen, besides an empty pupa-skin, both pro- 

 bal)ly belonging to tlie same species. 



FULGORID^E. 

 RiCANIA FLAVICOSTALIS, Sp. n. 



Exp. al. 20 nnillim. ; long. corp. 7 millim. 



Mule. Head yellow, with four keels ; vertex depressed, brown, 

 except at the sides and on the median line ; front quadricarinate, the 

 angles of the outer carinse very prominent, the middle ones hardly 

 projecting on the frontal edge ; all the carinae black, and with a short 

 dark line on the clypeus between them, the middle ones rather wide 

 apart, and meeting in a point at the extremity of the clypeus. 

 Thorax and abdomen blackish brown above, the thorax tricariuate, 

 varied with ferruginous on the sides and along the outer edges of the 

 two outer carinse ; abdomen with the second segment greenish, and 

 the base of the three following segments ferruginous. Under surface 

 of the body and legs yellowish ; the four front tibiae brownish above ; 

 abdominal segments edged behind with a green line ; the last two 

 segments reddish brown. Wings hyaline ; fore wings with the 

 costal space yellow as far as the black stigma, beyond which is a 

 hyaline space ; hind margin broadly purplish brown, intersected by 

 a curved line nearly parallel to the hind margin ; within the middle 

 of this runs a narrow vitreous stripe covering the outer half of seven 

 cells ; one or two very irregular series of transverse cells beyond the 

 middle of the wing, not even uniform on both sides; inner marginal 

 region tinged with yellow, but less strongly than the costa ; costal 

 cross-nervures not forked, but most of the apical nervures beyond the 

 stigma and on the hind margin are forked. Hiud wings hyaline, 

 brown along the hind margin, the first six or seven marginal nervures 

 from the tip furcate or bilurcate. 



The neuration of this and the two following species somewhat 

 resembles that of R. panorpa^formis, Spin. No dates of capture are 

 attached to any of the specimens. 



RiCANIA AFFINIS, Sp. n. 



Exp. al. 22 lin. ; long. corp. 9 lin. 



Male. Very similar to the last species, but darker above, the 

 brown bands on the clypeus beyond the inner carinse darker ; under 

 surface of body yellow, with irregular black markings beneath the 

 wings, and a large spot on the pectus between the first two pairs of 

 legs ; abdomen not banded with green above, but with a row of 

 yellow spots on the sides. Wings hyaline, not tinged with yellow on 

 the costa or inner margin, but with a yellow spot on the costa (like- 

 wise edged with black within) before the black stigma ; below the 

 stigma are some small brown blotches along the line of the inner row 

 of transverse cells ; there are also two small brown spots nearer the 

 base on the lower half of the wing ; hind margin brown for al)out 

 cue sixth of the width of the wing, and marked with two irregular 

 hyaline spaces, each covering several cells ; close to the hind margin 

 runs an interrupted row of small hyaline dots. Hind wings hyaline.
