5. T. Bondii, Z^^^^'^^^.s ; Morrisii, Mcijrick. — Expanse 1| 

 to 1^ inch. Thorax and abdomen slender ; fore wings chalky- 

 white, very faintly dusted with grey, and tinged between the 

 nervures with pale smoky-brown ; hind wings shaded from 

 white to smoky-brown. 



Antenna of the male short, simple, without perceptible 

 ciliation, white ; palpi slenderly tufted, white inside, brown 

 outwardly, apical joint rather long ; head smooth, white ; 

 thorax narrow, with long shoulder-lappets, white ; fascicles 

 white ; abdomen slender and rather long, smooth, brown-

 down ; costa a little arched at the base, thence very faintly 

 curved; apex bluntly rounded, almost angulated; hind 

 margin rather oblique, very obscurely rounded ; dorsal margin 

 nearly straight; colour smooth chalky-white with a super-

 nervures in the hinder half, or even over the whole surface, 

 yet hardly sufficient to produce any change in the chalky 

 whiteness of the whole ; no markings except a series of 

 black dots placed upon nervures, and indicating the usual 

 second line, much curved in toward the costa. These vary 

 in distinctness and number, but seem to be pretty constantly 

 present. Cilia white, absolutely continuous with the white 

 surface — that is, wholly devoid of any dividing-line. Hind 

 wings short toward the anal angle but elongated to the apex, 

 which is bluntly and suddenly rounded, the hind margin 

 there being somewhat elbowed and the portion below it 

 almost straight; greyish-white, shading off to pale smoke 

 colour along the hind marmu, where this forms an ill-defined
