288 PERCY SLADEN TRUST EXPEDITION 



greyish-wliite, crossed by five fuscous fascise of which the three basal are narrowest, 

 and all containing more or less prominent greyish-white spots, on costal margin near 

 apex are some distinct testaceous markings ; wings subhyaline, other structural 

 characters as in generic diagnosis. 



Long, inch tegm. 5 mm. 



Log. Seychelles. Silhouette : Mare aux Cochons plateau. Mahe : Cascade Estate, 

 about 800 feet. 



The description of this very distinct species has been derived from two carded 

 specimens, both of which have been used for that purpose. 



Genus Fescennia. 



Fescennia Stal, Hem. Afr. iv. p. 198 (1866). 



This genus was founded by Stal for the reception of a species described by Coquerel, 

 as Phenice bivittata from Mayotta Isld. and Madagascar. Stal however renamed it as 

 F. laticeps without giving any reason. Coquerel's description is much more obscure than 

 that of Stal's, but it was published in 1859, and should take precedence. I have 

 not seen the type of the genus, but the two species here described seem clearly 

 to belong to Fescennia. 



164. Fescennia himaculata, sp. n. (Plate 51, fig. 11 ffl). 



Body and legs pale ochraceous, more or less greyishly pubescent ; eyes testaceous ; 

 tegmina palely flavescent, a black spot near apex and a similar spot near middle of 

 inner margin ; wings subhyaline, with some opalescent reflexions ; head including eyes 

 about as wide as pronotum, vertex broad, triangular, the apex emarginate distinctly 

 projecting beyond eyes ; clypeus long, tricarinate, a little shorter than face ; second 

 joint of antennse very short ; mesonotum tricarinate, the sublateral carinations obscure ; 

 tegmina elongate, about three times longer than broad, beyond medium a little broadened, 

 about three times longer than clavus ; wings about a third part shorter than tegmina. 



Long. excl. tegm. 4 mm. Exp. tegm. 13 mm. 



Log. Mahe : Mare aux Cochons district, 1000—2000 feet. 



A single example only contained in the collection. 



165. Fescennia aurea, sp. n. (Plate 51, fig. 10 a). 



Body and legs pale ochraceous, more or less greyishly pubescent ; tegmina 

 flavescent with a black spot near middle of inner margin and the apical margin 

 narrowly fascescent ; wings subhyaline with opalescent reflexions. Allied to the 

 preceding species F. bimaculata, but the face a little broadened posteriorly, clypeus 

 a little narrower ; some minor differences in venation of tegmina better shown than 

 described in the figures of the two species. 



Long. excl. tegm. 4 mm. Exp. tegm. 14 mm. 



Log. Seychelles. Silhouette ; Mare aux Cochons. Mahe : Cascade Estate, about 

 800 — 1500 feet. A single example from each locality.
