 costa to well before apex, sUghtly pointed at posterior end; a transverse 

 spot in apex, a parallel streak of black suffusion, ending in a metallic 

 obhquely oval spot in apex and along upper half of termen; a small 

 wedge-shaped horizontal mark in middle of disc below anterior end of 

 preceding black streak, pointed posteriorly; a black horizontal broad 

 streak edging preceding spot anteriorly and below and running to 

 middle of termen; a large metallic spot in tornus, occupying less than 

 lower half of termen and tornus and emitting anteriorly two pointed 

 horizontal processes further than halfway towards cell, continued by 

 blackish lines; all markings narrowly, and those in apex and termen 

 broadly, edged with black; a jet-black spot on costa before apex con- 

 nected by a line of the same color along apex and termen with a similar 

 smaller spot on dorsum before tornus. Ciha bright orange, apical

The species is closely allied with L. lamprodesma Meyrick, from Java 

 but is larger, deeper orange, the markings differ slightly. The geni- 

 talia show considerable differences from those of the above named Jav- 

 anese species and are quite distinct. Apparently Meyrick refers to 

 this species in his description of lamprodesma, where he states: "I 

 have a closely allied undescribed species from the Philippines" 

 (Zool. Meded., vol. 7, p. 85, 1922). The long tufts of the hind tibia are 

 peculiar.
