As confirmatory of the fact that the Apple-worm

I last fall received specimens of this fruit, infested with it, from Geo. 

 T. Anthony, of the Kansas Farmer. 



ALREADY FOUND IN CALIFOIINIA. 



There were several reports, during the last year, that this in- 

 sect has been noticed in California; though how truthful they are, 

 I have no means of ascertaining. 



NATURAL ENEMIES— DISCOVERY OP TWO PARASITES. 



In addition to the two cannibal larv?e which I have described as 

 feeding on the Apple-worra, I can now add two genuine parasites to 

 the list of its enemies. It we except a species of hair-snake, belong- 

 ing probably to the genus Mermis., and which Mr. P. H. Foster, of 

 Babylon, New York, has found on two occasions infesting it,* no true 

 parasite of the Apple- worm has ever been discovered in this country. 

 I have the past year discovered two. Both of them are Ichneumon- 

 flies, and the first may be called 



[Fig. 26.] 



The Ring-legged Pimpla {Pimjyla annu- 

 lipes Br.) — This is a black lly, varying con- 

 siderably in size, the female sometimes 

 measuring but :j, at others fully ^ inch, ex- 

 clusive of ovipositor; the male somewhat 

 smaller. The genus Pimpla was briefly 

 characterized in my last Report, (p. 43), 

 where it was shown that this same species 

 attacks the Walnut Case-bearer (Acroia- 

 sis juglandis LeB.) I annex a lateral out- 

 line of a female Pimpla (Fig. 26). The 

 male has a more slender abdomen, which 

 is unarmed. 



Pimpla Axxunriis is black ; the abdomen rongli punctured above, with the borders 

 of the joints polished and inclined to brown. The tegulte ai"e white, and the leg's are 

 reddish, with the exception of the middle and hind tibiae, which are dusky — especially 

 the hind pair — and have a broad white annulus, sometimes indistinct on the middle 

 pair. The posterior tarsi are dusky, especially at tip. The palpi are pale-yellow. Cres- 

 son says it may be dlstiniruished from the other species of the genus, by the scutellum 

 being black, the te^uke white, and the anterior coxiie yellowish-red. 



This fly eats its way through the chrysalis and cocoon of the Cod- 

 ling-moth, without having previously made any cocoon of its own. It
