Platydasys, n. gen. 



Allied to the preceding genus and to Cotanda ; the wings of the 

 same form as in Dissolophus ; the antennae most like those of 

 Cotanda but thicker, the femora and tibiae of all the legs and the 

 tarsi of the middle and hind pairs very densely clothed with coarse 

 hair-scales. Type P. pryeri. 



Platydasys pryeri, n. sp. (Plate VI. fig. 6.) 



Sepia-brown with faint roseate reflections ; the primaries with 

 black and white lines and spots almost exactly as in the European 

 Methorasa latreillei ; but the renifonn spot is larger and more 

 indented in front, and the pink hastate spot immediately beyond the 

 sinuous black-edged white discal line and situated upon the upper 

 radial vein is much less prominent, so that it is scarcely distinguishable 

 from the remaining portion of the pale stripe bounding the external 

 edge of the disca! line. Expanse of wings 34 millim.

A fragment of the female was obtained by Mr. Pryer in Sanda- 

 kan. This species should be among the insects described by 

 Walker ; but, if so, the description is not good enough to render its 

 identification possible. 



PcECiLOGRAMMA, n. gen. 



Nearest to Gnamptocera, but in the pied character of its markings 

 very dissimilar, superficially, from any of the allied genera ; antennae 

 normal in character, with short sparse ciliations ; palpi broad, 

 compressed, curved obliquely upwards, with short terminal joint ; 

 collar and tegulae ample ; metathorax with prominent central crest ; 

 basal segment of abdomen probably tufted ; legs long, the front 

 tibifB broad, the external edge being densely fringed with coarse 

 scales; femora of middle pair of legs flattened and grooved, the 

 tibiae densely clothed with hair and with two long terminal spurs ; 

 posterior legs almost naked, the tibiae with the usual spurs. Type 

 P. picata. 



PCECILOGRAMMA PICATUM, U. Sp. (Plate VI. fig. 4.) 



Primaries above sepia-brown, spotted and streaked with black, 

 the internal area whity brown ; base white, marked with two black 

 spots, an oblique bisinuated white stripe from the base of the costa 

 to an oblique white band across the basal two-fifths of the wing, 

 the latter band is traversed by a black line and is angulated at its 

 costal extremity ; an oblique white streak from the apex, interrupted 

 by the reniCorm spot, which is white, oval, and encloses two unequal 

 black spots, and the postniedian stripe, which is white, internally 

 edged with black, zigzag and very irregular, a slightly sinuous 

 white submarginal stripe, connected on the second median interspace 

 by a white spot, with a marginal series of internally white-edged 

 black dashes ; fringe whitish, spotted with grey : secondaries grey, 

 with diffused darker external border : head and collar blackish, partly
