narrowing abruptly like the cut wood, while the following ones are relatively very 

 narrow, and resemble the lead ; the pointed anal extremity is armed with some 

 orange coloured or whitish hooked bristles. The colour of the whole pupa soon 

 darkens to orange-brown, and then gradually to black before the escape of the imago. 

 The fifth and sixth abdominal segments were the only " free " ones in the several 

 pupae examined, so most probably this is the case in both sexes. 



The pupa is enclosed in a small and closely-spun white silk 

 cocoon, well concealed between the united leaves of the shoot of the 

 food-plant. The moths emerged from June 7th to 14!th. 



It has been suggested to me before now that Aproasrema Sangiella, 

 Stn., is specifically identical with A. coronillella, Tr., but the idea is 

 quite untenable. Whereas the larva of the former, which feeds on 

 Lotus corniculatus, is, at any rate from an early stage and presumably 

 throughout, dark reddish-hrown or brownish-red, that of the latter, 

 which feeds on Goronilla varia, and has also been recorded as found 

 on C. minima, Vicia, Genista tinctoria. Ononis spinosa, Lathyrus pra- 

 tensis, Astragalus glycypJiyllos, A. hceticus, and Aster amellus, but not 

 on Lotus corniculatus, is, when feeding up, ^''greenish, spotted with 

 reddish, indistinctly towards the head, but more distinctly posteriorly," 

 and when full-fed is no longer green, but " pale amber, with the red 

 spots more distinct," as described by Staintou in Nat. Hist. Tin., vol. 

 X, where the imago, larva, and mode of feeding are also figured. The 

 distinctions between the imagines are much less obvious, but Stainton 

 points out that A. Sangiella has the fore-wings longer, narrower, and 

 more pointed, the costal spot more oblique, and the dorsal spot less 

 distinct, than coronillella, and has also when in fine condition a decided 

 bluish gloss, which is wanting in the latter. Meyrick lays stress also 

 on the difference in the colour of the pale spots, which are pale 

 ochreous in coronillella, but ochreous-whitish in its ally. As regards 

 the shape, direction, and distinctness of these spots, it must be added 

 that they vary immensely in Sangiella. The distribution of both 

 species seems in Britain to be strangely limited, for whereas coronil- 

 lella is only known to have occurred at Mickleham, in Surrey, where 

 Stainton suggests that the larva probably feeds on Onohrychis sativa, 

 Sangiella has, I believe, never yet been met with outside the county of 

 Durham.
