LARENTIA, Treitschke. 

 Larentia geminata. n. s. (Plate 3, fig. G, %.) 



White. Anterior wings white or whitish, crossed by five broken 

 black bands followed or preceded by continued yellowish testaceous or 

 olivaceous shades. Extreme base, white, with a testaceous shade. First 

 band (basal) entire, continued, irregularly and angulatedly sinuate, 

 followed by a nearly coincident testaceous shade. Second black band 

 usually more distinct and furcate before costa, below which it forms a 

 series of black dots to internal margin. The third is also usually 

 furcate at costa, thence maculate to internal margin, composed of a 

 double series of black spots, more or less connected with the fourth 

 band by black scales clothing the nervures below the disc, and pre- 

 ceded by a testaceous shade band. The fourth band is more continu- 

 ous than the third, similar in appearance, being likewise furcate on 

 costa, below which it is chiefly composed of black scale patches on the 

 nervures of which there is a double series. Here, the wing is tra- 

 versed by one or two testaceous shade bands, more or less coalesced and 

 undefined. Fifth band more continuous than the rest, usually broken 

 on the interspaces between the second and fourth median nervules, an- 

 gulated on the interspaces, followed by a sub-obsolete series of inter- 

 spaceal dots and by a testaceous shade ou the terminal space. A 

 terminal, black, macular line, interrupted at the middle of the inter- 

 spaces. Fringes whitish. 



Posterior wings whitish ; a faint geminate subterminal band com- 

 posed principally of dark scales on the nervures. Fringes whitish. 



Under surface pale, reflecting the ornamentation of the upper sur- 

 face on both pair. 



Head, white; palpi black beneath; a frontal black line between the 

 antemm) ; prothorax with a testaceous tinge. Thorax and tegulaj 

 whitish, spotted with black. Abdomen whitish, with scattered black 

 scales; terminal segment prominently marked with black above; anal 

 hairs whitish. Legs whitish, with black streaks on the outer surfaces. 

 Antenna? simple.

 conspicuous irregular black bands associated with faint yellowish coin- 

 cident shades.
