This species differs from Hampson's diagnosis of Surattha in fol- 

 lowing items: 



Antenna simple, not bipectenated. 



Tibial spurs, both pairs nearly same length, outer at least three- 

 fourths as long as inner. Otherwise the venation is identical with 

 Hampson's figure. The conical process on front of head is a curious 

 chitinous extension of the clypeus (?), and is no doubt used by the 

 moth for effecting its escape from its probably earthy, dry, and 

 hard pupal habitation. Fig. 3 shows outer end of fore wing. 



SURATTHA INDENTELLA, new species. 



Expanse, male, 22.5-23.5 mm. 



Head white in front, light ochreous above; labial palpi white in- 

 ternally, externally pale ochreous, shaded with brown at apex; 

 maxillary palpi pale ochreous; antenna bipectinate, with long- 

 branches, stalk whitish, branches blackish brown; thorax creamy 

 ochreous, the outer ends of scales slightly darker, especially of 

 patagia?; abdomen light grayish ochreous, posterior edge of each 

 segment narrowly white above, the three first segments shaded with 

 ochreous above; legs whitish, dusted with pale ochreous. 



Fore wing, ground color creamy ochreous ; the outer ends of scales 

 are light brown, giving a speckled appearance under lens; there is 

 a dark brown oblique fascia from inner fifth of costa to inner third 

 of dorsum, almost obsolete at costa, but broad and well defined on 

 low^er four-fifths ; a dentate transverse brown line at middle of wing, 

 Avith two strong outward spurs; both the basal fascia and the den- 

 tate inner line are edged on both sides by paler lines. The subtermi- 

 nal line from outer sixth of costa is only slightly oblique to upper 

 third, then slightly convex to outer fifth of dorsum, it is white, over- 

 laid with shining pinkish scales ; inwardly it is defined by a dark brown 

 line ; below middle of wing the white extends into marginal space and 

 is marked by three horizontal black dashes; above middle, ground 

 color is brown w^ith a whitish cloud before apex. Terminal edging 

 brown. Between subterminal line and inner dentate line is a small 

 brown discal dot on upper third of wing. Cilia whitish ocherous, 

 shaded with light fuscous, cut by a white dash at middle ; above this 

 the basal half of cilia is conspicuously darker than outer. 



Hind wing, dark smoky brow^n, paler toward base, cilia whitish; 

 underside lighter, with a whitish streak from base to termen, through 

 middle of cell and between veins 4-f 5 and 6. Underside fore wing 

 light ochreous brown. 



Two male specimens, from National Museum collection, Amarillo, 

 Texas, August 30, 1902, Cockerell. 



Cotypes. — Cat. No. 11048, U.S.N.M., and in Author's collection. 



The venation and structure of this species agrees exactly with 

 Hampson's, fig. 47, p. 9G5, Proc. Zool. Soc. Lond., 1895, except that 

 termen of fore wing is slightly indented at veins 4 and 5.
