and this would destroy, incidentally, the breeding grounds of the 

 Scolytid beetles such as Tomicus laricis, Hylurgus piniperda, &c. 

 Further, it would be as well to limit the growth of heather 

 (unless required for game purposes) for the same reason. None 

 of the above spiders and Phalangids, except the Drassids and 

 Lycosids, are averse to living in trees, for I have beaten 

 nearly all from conifers, and they would form an effective patrol 

 for the woods when C. laricella was out as an imago, and, 

 incidentally, in the case of the small forms, many Aphids would 

 be captured, and in the same way the larger forms would secure 

 many beetles and sawflies. 



In all of the woods examined, beetles, either weevils or bark 

 beetles, were but few in numbers, and have never at any time 

 caused appreciable damage. Possibly the commonest beetles in 

 the woods were the Coccinellids mentioned above, and Rhagium 

 bifasciatum. As was said, the ladybirds are friendly insects, 

 and in all probability Rhagium should be placed in the same 

 category, as its larva feeds on, and demolishes, decaying stumps 

 which otherwise would be lurking places for destructive insects 

 of all kinds. 



It was said that Phigalia pedaria (the Brindled Beauty Moth) 

 was in sufficient numbers to affect the foliage of the larch in the 

 larval condition. It can never become such a pest as C. laricella, 

 for it emerges at a time when insect food is scarce, and owls 

 make short work of it, as the huge number of wings lying about 

 in March and April shows. It is only the immense quantity of 

 eggs laid by the wingless females that keeps its numbers up. 



NEW BUTTERFLIES FROM NIAS.

$ . Upper side. Fore wing with costa, apical third and outer 

 margin blackish, three submarginal white spots ; hind wing white, 

 outer margin blackish, enclosing three white spots on inner edge. 



Under side. Fore wing white, apex yellowish, a subapical 

 blackish band containing a white spot between upper and middle 

 median nervules ; hind wing uniform yellowish. 



This appears to be a rare species. There are ten males and 

 the female here described, which is, I believe, unique, in Coll. 

 Adams. 



* The types of all the species described in this paper are in the Adams 

 Collection, which is now at the Natural History Museum, South Kensington.
