 figs. 16 a, b (1909). 



Lac. Amirantes : Desroches Island, 1905. Seychelles : Mah^, Praslin, Silhouette, 

 from near sea-level (not fi-om the mountain-forests). 



I have figured a variety in which the markings of the tegmina are darker and 

 the basal joint of the antennse paler than in the type previously delineated. 



204. Ugyops facialis, sp. n. (Plate 49, fig. 2 a). 



Body above ochraceous ; vertex of head with four black longitudinal lines ; pro- 

 notum with a few dark spots on each lateral area ; mesonotum with five longitudinal 

 dark carinate lines which are usually black ; abdomen spotted and suffused with 

 castaneous, especially on disk and lateral margins ; body beneath and legs ochraceous, 

 face darker in hue and suff'used with small paler and darker macular markings ; 

 tegmina subhyaline, the venation darker, the longitudinal veins considerably ochraceously 

 broken, a series of longitudinal veins crossing disk of tegmina beyond middle and 

 a few transverse veins before apex ; wings hyaline, the venation fuscous ; antennse 

 with the first and second joints ochraceous, about apical half of second, black ; head 

 with the central lobe distinctly prominent at apex, face long, narrow and prominent, 

 extending for some distance before eyes, moderately widened from about anterior margin 

 of eyes and again slightly narrowed before clypeus, central longitudinal ridge promi- 

 nent, duplex for about anterior half, lateral margins distinctly reflexed ; tegmina a 

 little more than three times as long as broad. 



Long. excl. tegm. 7 to 7f mm. Exp, tegm. 20 mm. 



Loc. Seychelles. Silhouette : near Mont Pot-k-eau, all over 1000 feet, and from 

 Mare aux Cochons and forest above. Mah6 : Mare aux Cochons district, over 1000 feet. 

 Aldabra : 1908 (Fryer). In contrast to the preceding species, this species was found 

 in the Seychelles at considerable elevations and in endemic-forest districts. 



205. Ugyops seychellensis, sp. n. (Plate 49, fig. 4 a). 



Body and legs bright castaneous, lateral longitudinal sulcations to face, black; 

 tegmina pale bronzy-brown, the veins darker, a few linear darker markings on claval 

 vein; wings subhyaline, the veins fuliginous; head projecting a little beyond anterior 

 margins of eyes; face elongate ampliated beyond eyes towards clypeus, prominently 

 centrally longitudinally carinate, the lateral longitudinal black sulcations, profound ; 

 antennee brownish-ochraceous, first and second joints robust ; pronotum strongly centrally 

 ridged ; mesonotum with five longitudinal ridges ; abdomen distinctly centrally ridged ; 

 tegmina with the veins more or less distinctly finely setigerous ; posterior tibiae with 

 three distinct spines.
