tected by the larval skin, which merely splits on the back and is 

 loosened from the inclosed body, instead of being entirely worked off 

 behind, as is the normal fashion with insects. On apple-trees, they 

 usually crowd together on the rougher portions of the trunk, where 

 the general similarity in color to the surroundings renders them 

 sufficiently inconspicuous ; but on the pines, they more frequently 

 congregate around the ends of the twigs, which then appear as if 

 covered with prickly burs, reminding one strongly, as Dr. Fitch well 

 observes, of the ripened spikes of the Hounds-tongue {Cynoglossum 

 oMcinale)^ and presenting a decided nole-me-tangere aspect. 



The manner in which this memberless pupa shrinks and separates 

 from the armed and membered larval skin furnishes a good illustra- 

 tion of that in which the larval scale of the Bark-louse itself is 

 formed; and, were the skin ruptured below and behind instead of 

 above and before, and strengthened by a secretion from the retreat- 

 ing body, the analogy would be perfect. As I have found the full- 

 grown larva as early as the first of April, there is every reason to 

 believe that the Twice-stabbed Ladybird hibernates both as larva 

 and beetle. 



Still another insect of this family, namely, the Painted Ladybird 

 {CoGGinella piota Randall), I have discovered preying on our Pine- 

 leaf scale, as well as on the afore-named Chennes. 

 The beetle (Fig. 37 c, enlarged ; J, natural size) is 

 of a pale clay-yellow or straw color, marked with 

 black as in the figure ; and its dusky-brown and 

 paleryellow larva (Fig. 37, a) has never before 

 * been connected with it or described. Hence I sub- 

 join the following description : 



CoccixELLA PiCTA Rauclall. — Larva — Form normal, rather stout, 0.36 inch long 

 when full grown ; 12 joints, exclusive of head. Color dark sooty -brown, with a medio- 

 ■dorsal pale yellow stripe, narrowing at each extremity, broadening posteriorly on 

 thoracic joints, and brightest on joint 3 ; a similarly pale lateral stripe. The ordinary 

 tubercles — 4 dorsal rows on abdominal joints, the two each side coalescing on the tho- 

 racic joints — polished black, with short bristle-stubs. Described from 3 specimens. 

 Pupa — naked and suspended. No description taken. 



It is not so numerous as the Twice-stabbed Ladybird, which is, 

 perhaps, to be accounted for by the fact that its helpless pupa is not 

 protected by any such mimic cJievaux-de-frise. 



REMEDIES. 



Few trees suffer more from the loss of their leaves during sum- 

 mer than do the pines. Mr. Thos. Meehan, though not supported by 

 many other botanists, considers that, physiologically, they are not 

 true leaves, but half leaf, half branchlet ; and, however, much truth 

 there may be in such a view, it is certain that they can not be replaced 

 by new ones, as true leaves often can. But I have experimentally
