108 ME. F. "WALKER ON HETEROCEROUS LEPIDOPTERA 



95. Lithosia discalis, n. s. Mas. Testacea, antennis subsetulosis, 

 abdominis fasciculo apicali compresso, alis anticis vix acutis litura dis- 

 cali gibba nigricante fasciculata. 



Male. Testaceous, rather flat. Antennae minutely setulose. Abdomen 

 with a compressed apical tuft. Fore wings hardly acute, with a gib- 

 bous blackish tufted mark on the discal areolet, which is concave be- 

 neath ; costa hardly convex ; exterior border very oblique. Hind 

 wings paler. Length of the body 3^ lines ; of the wings 8 lines. 



Gren. Blayia, n. g. 



Mas. Corpus gracile. Proboscis subobsoleta. Palpi brevissimi. An- 

 tenna breviusculae, setulosae. Abdomen alas posticas vix superans, 

 fasciculo apicali parvo. Pedes graciles ; femora sulcata ; tibiae pos- 

 ticae calcaribus quatuor longiusculis approximatis. Alee elongatae ; 

 anticae apice rectangulatae, costa recta, margine exteriore subobliquo 

 vix convexo. 



Male. Body slender. Proboscis almost obsolete. Palpi very short. 

 Antennae rather short, distinctly setulose. Abdomen hardly extend- 

 ing beyond the hind wings ; apical tuft small. Legs slender ; femora 

 furrowed; hind tibiae with four rather long approximate spurs. 

 Wings elongate, moderately broad. Fore wings rectangular at the 

 tips ; costa quite straight ; exterior border hardly convex, slightly 

 oblique ; 2nd superior vein forked near the base ; no 3rd or 4th infe- 

 rior veins. 



This genus, perhaps, may not belong to the Lithosiidce.

 brown towards the exterior border. Length of the body 3 lines ; of 

 the wings 8 lines. 



Gen. Mantala, n. g.

 frontem perpaullo superantes, articulis indistinctis. Antenna se- 

 baceae, compresssc, subserratac, setulosae, basi robustae. Abdomen alas 

 posticas non superans, fasciculo apicali parvo. Pedes sat validi; 

 tibiae posticac quadricalcaratae. Alee elongatae ; anticae apicc rotun- 

 datae, areola discali fimbriate, costa vix convcxa, margine exteriore 

 sat obliquo. 



Male Body rather slender. Proboscis distinct. Palpi porrcct, ob- 

 tuse, extending very little beyond the front; joints indistinct. An-
