the Lepidoptera of St. Helena. 
much pointed exteriorly just below the costa, and continued 
obliquely to the inner margin (where it becomes more suf¬ 
fused and patch-like) ; whilst the second one (which is better 
defined) is angulated in the same way below the costa, and 
almost joins (anteriorly) a conspicuous brownish spot on the 
inner margin. The extreme tip of the apex is white, trun¬ 
cated by a straight narrow black line. Hind wings pale 
smoky glossy white, the outer margin having a black line at 
the apical angle. Thorax concolorous with the anterior 
wings ; body similar in hue to the posterior ones. 
This extremely small Prionapteryx (which Professor Zeller 
observes is the smallest known to him) does not appear to be 
common ; indeed, judging from my own observations, it is 
decidedly rare, the very few examples which I obtained 
having been met with at West Lodge, immediately beyond 
the house. It was about the foliage of the common white 
Brugmansia , or “moon plant,” that I captured my specimens; 
but whether the habitat was merely an accidental one I am 
unable (not having observed the larva) to say. I have dedi¬ 
cated the species to the Rev. II. Whitehead of Woodcot, from 
whom we received much kindness and valuable assistance 
during our six months’ residence at St. Helena.

This single little representative of the Phyckhe appears to 
be decidedly a scarce moth at St. Helena, and one which 
occurs (so far, indeed, as I am able to judge from the capture 
of merely two individuals) at intermediate altitudes. One of 
my examples was taken at Plantation, and the other from 
an old gumwood between Peak Hale and Lufkins; and I 
think it far from unlikely, therefore, that the species belongs 
properly to the now fast disappearing gumwood fauna. If 
so, we may expect it to be found more abundantly in the few 
spots where those curious and interesting trees are still left; 
and the probability that the Plantation district was once 
well supplied with gumwoods, is rather in accordance with 
this supposition.
