which it may be confused, but is distinguished from it 

 by the subterminal Hne being further from termen and 

 more obhque, and consisting mainly of black points on 

 the veins with some yellow hairs mixed; by the shorter 

 palpi, the hght fascia in the cell being more diffused, and 

 by the hind-wing having 4, 5 stalked. Vein 11 of fore-wing 

 anastomoses with 12 as in C. sectitermina. 



Crambus lacteella, sp. n. 



Female. Head, palpi except at the sides, thorax, both wings on 

 upper- and hind-Aving on underside pure white; abdomen Avhitish, 

 tinged at basal half with ochraceous-buff ; palpi at sides and maxil- 

 lary palpi at basal half, tegulae and patagia ochraceous- tawny 

 (xv) ; fore-wing with the costal area at basal half and a fascia below 

 the cell ochraceous-tawny ; this fascia is sharply defined on upper 

 edge and diffused at lower edge; costal and terminal area, and 

 inner- marginal area above vein 16 for two- thirds of wing irrorated 

 Avith jjinkish-buff (xxix), except on the veins, which remain white; 

 a pinkish-buff diffused streak in cell; black terminal spots on the 

 veins from veins 2 to 8; cilia white, with a line of pinkish- buff at 

 one-third and tipped with the same colour. Hind-wings pure 

 white, slightly irrorated with pinkish- buff ; cilia pure white. 



Underside : — fore-wing densely irrorated with hair-brown except 

 on inner- marginal area and near termen; cilia as above; veins 

 even darker than on upperside. Hind-wing white; costal area 

 irrorated with, hair- brown. Fore- legs on outerside hair- brown, 

 mid- and hind-legs and abdomen on underside vinaceous-bulf (xl). 



Exp. 24 mm. 



Hab. Only one female specimen from Waterval Onder, 

 21. xi.' 1910. 



According to Mr. Tams this species is very close to 

 C. mesomhreUvs Hmpsn., which is unknown to me. 



Fore-wing moderately broad for a Cramhus, costa some- 

 what hollowed out at middle, apex acute, termen oblique 

 and rounded towards tornus, veins 4 and 5 connate at 

 base for a short distance; 11 anastomosing with vein 12. 

 Hind- wing large, semicircular; 2 from before middle of 

 wing; veins 4, 5 shortly stalked. Palpi over two times 

 head; antennae very shortly ciliate. 



Diatraea argentisparsalis Hmpsn., fuscata, var. no v. 



Male, female. Fore- wing densely irrorated with fuscous 

 and the medial and subterminal lines are often noticeable
