THE little series of Lepidoptera of which the following is an 
account was obtained by Dr. W. F. Dale, and sent to Mr. J. 
Hartley Durrant, who forwarded it to me with the request 
that I would name it. 
The collection contains ten species represented by about 
forty specimens, and is interesting as a contribution to a little- 
known fauna. So far as I can judge, it seems to show 
greater affinity to that of Chili than to any other. 
1. Argynnis siga. 
Argynnis siga, Hibner, Samml. exot. Schmett. Zutr. figs. 677, 678 
(1832). 
One example. 
This is the only butterfly in the collection. No Sphinges 
or Bombyces were obtained ; indeed, the most largely repre- 
sented tribe was the Noctuites. 
2. Agrotis hispidula. 
Agrotis hispidula, Guenée, Noct. i. p. 293. n. 476 (1852). 
Five examples of this somewhat variable species; it was 
originally described from Chili. 
3. Agrotis Dale, sp. un. 
This insect has somewhat the aspect of a Nonagria ; it 
has, however, very coarsely spined tibiee and the antenne: 
are ‘strongly pectinated, each pecten being finely ciliated on 
each side. Primaries above pale sericeous buff (almost dead 
gold in tint) ; costal half sparsely, irregularly, but distinctly 
speckled with black ; a curved discal series of similar black 
flecks from near costa almost to inner margin beyond the cell ; 
a few fine scattered black dots near outer margin and a well- 
defined marginal series; fringe of inner and outer margins 
pale cupreous or rufous-brown, traversed by two grey lines: 
secondaries grey, slightly darker on external border; fringe 
buff, shading into reddish ochreous towards apex: head and 
collar testaceous, the face slightly yellower ; antenne ferru- 
ginous 3 thorax sordid pale buff; abdomen grey, with pale 
ferruginous lateral and anal tufts. Primaries below smoky 
grey, slightly blackish at base of costa; base of median and
