points ; the fine hairs are smaller than in rnmicis, and being 

 black easily elude notice, at least on segments 12 and 13. 



Acronycta {Viininia) myricce. — My acquaintance with this 

 species is not of that intimate character that results from 

 frequently meeting with it in its natural home. I have only 

 once captured the larva in Great Britain, and not unfrequently 

 the same or a closely allied form in Switzerland. I have, 

 however, several times reared the larva from the Q.gg. 



I have not learned the precise limits of its range in Great 

 Britain. Its head-quarters appear to be at Rannoch, and that 

 portion of Scotland to the north-east of Rannoch. Whether 

 it occurs in the north-west of Scotland I do not know ; it does 

 not occur in the south, and as regards the west and south-west 

 my solitary capture was made in Argyle shire, where it must be 

 excessively rare, probably an occasional immigrant, or I should 

 have seen more of it. 



It appears to emerge in its northern habitat as early as 

 ruinicis and its congeners do in the south, that is to say, in the 

 first half of June, or later in some seasons. 



The &g% is laid in the imbricated manner characteristic of 

 Viininia, but in smaller batches, and more often solitarily than 

 in the other species. It differs also by varying in size more 

 frequently than any of the others do. Two adjacent eggs, for 

 example, measured in diameter i mm. and 1.33 mm., the 

 average being about 1.15, and the height 0.5 mm. ; the ribs 

 are about 66 in number. The colour is somewhat richer than, 

 say, rnmicis has, the yellow soon becoming of a pale salmon pink, 

 and passing on to a purplish brown, with paler reddish brown 

 spots ; these pale areas are smaller and more irregular than in 

 anricoma, but preserve more the form of separate roundish 

 spots than they do in ruinicis, where they run together and 

 form bands and streaks. 



The ribs unite together somewhat regularly as they approach 

 the vertex; there are no transverse stris, but the ribs are 

 waved or crenulated much as in the other species of the genus. 



The newly hatched larva is almost impossible to distinguish 

 by description from that of the other species of Viniinia ; after 

 it has fed a few days each species differs somewhat in the 

 aspect of the pale markings of the pale segments, and can be 

 distinguished when compared together. These differences are 

 fully shown in the drawings of these larvae. The length is 

 2 mm., with hairs as long, the hairs are black and vary in 

 thickness, looking nodulated when magnified. The predomi-
