aiitumnafa, are referred by Mr. Prout to dilutata var. christyi. 

 In addition to bred specimens. I captured a fair number of 

 autmnnata this j'ear. Of the captured specimens only one was a 

 female, and only one was seen at rest on an alder trunk. All 

 the others were disturbed from the alders, as in 1898, though 

 this year they seemed not to fly so high. 



A. few notes on 0. fiUgrammaria by way of contrast. It 

 occurs on the open moors in Lancashire, and may be found at 

 the end of August and in the first half of September, at rest on 

 stone walls, where it is easily captured without net. I believe 

 it may also be taken at dusk. It is smaller than autumnata, and 

 runs into glossy dark brown forms, such as do not seem to occur 

 in autumnata, though the lighter forms oi Jilicirammaria resemble 

 autumnata very closely. The larvae of 0. filigrammaria hatch 

 early in February. They have in all stages distinct yellow 

 stripes in addition to the spiracular line, differing in this 

 respect from O. autumnata, though, like it, they never show 

 any trace of purple marking. 



CARADRINA AMBIGUA IN HAMPSHIRE. 

 By J. Hy. Fowler. 



During the last week in September I put about a dozen 

 females of Caradrina amhigua in a box amongst primrose leaves, 

 and succeeded in obtaining some hundreds of ova, which were 

 deposited indiscriminately upon the leaves and on the sides of 

 the box ; the ova were very small, pale yellowish white. The 

 larvae hatched out in about sixteen days' time, and were long and 

 thread-like, at first dark brown grey in colour, and hairy. As 

 they grew to full size they became much less hairy ; they had 

 two hairs upon each segment, forming a row lengthwise upon 

 each side of the dorsal stripe, each hair placed upon a slight 

 pale tubercle ; the spiracles black and hairy ; numerous very 

 short grey hairs scattered about the body also. 



When full grown the larva is just an inch long, stout, and 

 onlj' slightly tapering towards the head ; it is several shades of 

 brown and grey, underneath a little paler than the sides, lateral 

 stripe semi- double and yellow, bordered broadly dark brown 

 with fine black lines, which radiate into the dorsal stripe ; 

 dorsal stripe light brown, narrowing towards the head, latter 

 small and shining brown, divided by a yellow V, which contains 

 a black dot in the middle. The first three segments are more or 

 less dark all over ; on the upper surface is an interrupted white 

 line bordered with dark brown, followed by eight arrow-head 

 markings, the barbs being hair-like, with the terminals having 

 distinct dots ; the anal spot is long and centred with paler. I
