being suffused with blackish, some darker dashes 
under the spiracles, and a darker irregular central line. 
These larvee formed compact little cocoons in the 
sand, and one bit up a piece of paper, and made itself 
a very neat little envelope. (J. Hellins, July, 1868 ; 
H.M.M., September, 1868, V, 98.) 
ACIDALIA BISETATA. 
Pl CXVIL, fig: 3. 
Hees sent me by Mr. Doubleday on the 26th July, 
1867 ; larve hatched on the 30th; fed on Polygonum 
aviculare and withered bramble leaves; spun up in 
May; moths out June 20th to 25th, 1868. 
he egg of A. bisetata is obtusely oval in outline, 
not quite cylindrical, but rather depressed ; irregularly 
covered with fine shallow reticulation ; colour salmon- 
pink, with large spots of deeper tint. 
Putting A. imitaria in its place as the lengthiest of 
the Acidalia larve, and A. rusticata as the stumpiest, 
A. bisetata seems to occupy a middle station, and, as 
far as I have seen, to form the connecting link between 
the two forms; being more slender and of more 
uniform bulk than the short larvae, and more rugose 
than the long ones. 
When full-grown, length about three-quarters of an 
inch, in form slightly flattened, slender, tapering very 
gently towards the head, which is notched, and scarcely 
smaller than the second segment; skin rugose ; bristles 
slightly clubbed; position m repose something lke 
that of A. scutulata. The colour is variable; I think 
I have seen three good varieties. 
Var. 1.—Ground colour dingy drab, warmer on 
the back, and duller below; the six segmental folds 
between four and ten showing as_ broad blackish- 
brown bands round the body, and shaped on the back by 
some dark oblique dashes, which reach to the spiracles, 
into a sort of broad, clumsy A, pointing forward ; there 
is a double dark brown dorsal line to be traced where
