466 DR. 1. A. CHAPMAN ON THE SPECIES [ Apr. 27, 
indistinguishable from those of L. owgarra (placidula) from New 
Guinea. 
1 entertain no doubt that they are races of one species. The 
green tone of tlhe upper surface is a confirmation so far as it goes. 
The differences are the large amount of white on the upper 
surface of tenella, of which owgarra shows no indication in any of 
the specimens I have seen but in one specimen of placidula there 
are distinct white areas; and that on the under side the mark- 
ings are much blacker in éenella, but the marginal markings have 
only the marginal spots, at least the arched line that surrounds 
them in placidula (and a majority of Lycenopsids) is only faintly 
indicated.

The clasps are very short and broad, and very broad at the 
extremity, the spinous process is minute and fused to the margin 
of the clasp along the dorsal third of the extremity. 
It is very similar to melena and to singalensis. The clasp is 
much broader than in melena, and singalensis is larger and has 
the terminal half of the clasp distinctly narrowed.
