Subfamily Tropiduchinse. 

 Daradaxoides, gen. nov. 



Head long, strongly produced, longer than pronotum, almost as long as mesonotum, 

 the lateral margins somewhat obliquely straight from base to anterior margins of eyes 

 and then obliquely narrowed to apex which is truncately rounded, the margins strongly 

 ridged, and a central longitudinal ridge ; eyes longer than broad ; face long, centrally 

 and laterally ridged, slightly concave at region of eyes, obliquely narrowed before apex ; 

 clypeus short, broad, centrally ridged ; pronotum short, discally, conically produced 

 between the eyes where it is centrally and laterally ridged, depressed at lateral areas, 

 the lateral angles prominent behind eyes, posterior margin angularly concave ; meso- 

 notum strongly, discally tricarinate; posterior tibise with three spines a little beyond 

 middle ; tegmina a little more than twice as broad as long, costal membrane slightly 

 broader than radial area, the first and apical margin closely obliquely veined, the 

 second more sparingly veined, the discal veins longitudinal for about two-thirds from 

 base, the subapical area more or less reticulate ; wings shorter than tegmina, the 

 posterior margin moderately waved, longitudinally veined except on apical area where 

 the veins are more or less furcate. 



Allied to Daradax Walk., a genus represented in Malacca and Borneo. 



161. Daradaxoides mahensis, sp. n. (Plate 49, fig. 5 a). 



Body and legs pale virescent ; eyes a little darker and more testaceous in hue ; 

 tegmina semiopaque, the veins pale virescent ; wings hyaline. Structural characters 

 as in generic diagnosis. 



Long. excl. tegm. 5^ to 7 mm. Exp. tegm. 12 to 15 mm. 



Log. Seychelles. Mahe : 5 specimens ; from near Morne Blanc ; Cascade Estate ; 

 top of Mount Sebert, nearly 2000 feet ; Mare aux Cochons district, 1000 — 2000 feet. 



Subfamily Achilinse. 

 Paeakosalya, gen. nov. 



Head including eyes a little narrower than pronotum, vertex longer than broad, 

 distinctly projecting before eyes, its margins carinate and with a distinct central ridge ; 

 face longer than broad, towards clypeus moderately ampliate, laterally and centrally 

 ridged ; clypeus about half as long as face with a strong central ridge and its lateral 

 margins carinate ; pronotum short, centrally tricarinate, posterior margin strongly 

 angularly emarginate ; mesonotum, slightly longer than vertex and pronotum, tri- 

 carinate ; legs long and slender, posterior tibiae with one spine before middle, posterior 

 tarsi with the basal joint very long ; tegmina apically moderately widened, distinctly 

 amphate behind the clavus, two series of more or less complete transverse veins on 

 apical half, wings considerably wider than tegmina. 



Allied to the Oriental genus Kosalya Dist., from which it differs by the longer 

 and more projecting vertex of head, the different shape of the face, the shorter meso- 

 notum, and only one spine to the posterior tibiae.
