by the delicate cocoon. None, so far as we know, seek the larva in the apple. Professor 

 Riley states that the Pennsylvania soldiev-heetle {Chauliorniathus pennsylvanicus, DeG.),and 

 the two-lined sol Aier-heetle{ Tel ephorus bilineatus, Say), in their larval states feed upon the 

 larvre of the codlin moth after they have issued from the apples. He also mentions the 

 fact that the larvte of a species of Trogosita also helps in this good work. Dr. LeBaron 

 treats of this insect at some length, but of late years it has not been found. The species 

 has never been determined. Mr. Koebele has recently sent us from California two Der- 

 mestid beetles, which are stated to destroy the pupse of the codlin moth. These are Tro- 

 goderina tarsale and Peri meg atoitia variegntum. Experiments made indicate that they will 

 kill the chrysalids in confinement, but as to destroying them in the open air on trees we 

 have no absolute evidence. Mr. Koebele has, however, been instructed to make close 

 observations upon this point. An undetermined soldier-bug was observed by Mr. G. W. 

 Shaw, a correspondent of Dr. LeBaron's, who states that he has actually observed the bug 

 to pierce an apple with its beak and draw out the apple-worm, which, however, is a state- 

 ment which may be taken with a great deal of allowance. An unbred and undetermined 

 coleopterous larva was received by Professor Riley, in 1874, from Professor A. J. Cook, 

 with the statement that it fed upon both larvre and pupre of C'arpocapsa pomonella. This 

 larva, according to Professor Riley's notes, bore a close resemblance to that of the Clerid 

 Necrobia riifipes — the red-legged ham-beetle. 



Both the Pimpla and Macrocentrus are figured in the report of tlie United 

 States Department of Agriculture of 1887. 



PEACH MOTH. 



Order, Lepido-ptera ; Family, Tineidse. 



Anarsia lineatella, peach moth, or straivberry root borer (Figure No. 26), 

 which has of late become quite a serious pest in our orchards, has likely- 

 been imported on strawberries, on the roots of which it feeds in the Eastern 

 States. I am not aware that it has proved anything troublesome to the 

 strawberry growers, although it is possible that it does some damage. It 

 must not, however, be confounded with the borer generally infesting straw- 

 berries in this State, which lately has been determined by Professor Riley 

 to be the larvse of a clear-winged moth (xgeria impropria. H. Edwards). 



As the insect demands general attention, we have deemed it well to have 

 an illustration of it, copied from Saunder's " Insects Injurious to Fruits," 

 from which I also take an account of its habits in the Eastern States. 



When occurring in great numbers, this insect is very injurious, playing 

 sad havoc with the strawberry plants. The borer is a small caterpillar, 

 nearly half an inch long, and of a reddish-pink color, fading into a dull 

 yellow on the second and third segments; the anterior portion of the sec- 

 ond segment above being smooth, horny-looking, and brownish yellow, like 

 the head. On each segment there are a few shining, reddish dots, from 

 every one of which arises a single, fine, yellowish hair. The under surface 

 is paler. This borer eats irregular channels through the crown, sometimes 

 excavating large chambers, at other times tunneling it in various direc- 

 tions, eating its way here and there to the surface. If examined in the 

 spring, most of the cavities will be found to contain a moderate-sized, soft, 

 silky case, nearly full of castings, which doubtless has served as a place of 

 retreat for the larvse during the winter. 



Early in June, when mature, the caterpillar changes to a small, reddish- 

 brown chrysalis, either in one of the cavities excavated in the crown, or 

 among decayed leaves or rubbish about the surface, from which the moth 

 escapes early in July. 



The moth is very small, of a dark-gray color, with a few reddish-brown 

 spots and streaks on the fore wings. The fringes bordering the wings are 

 gray, tinged with yellow. Tlie nioth lays an egg on the crown of the plant 

 late in July or early in August, which soon hatches; the small cateri)inar 

 burrows into the heart of the plant, and remains in one of the chambers 

 during the winter, occupying one of the silky cases referred to. The
