This species occurred with, but was uot so abundant as, Ccvriophanes 

 utilis Cr., tlie parasite of L. cinereuN, previously mentioned. 



Meteorus orchesiw Aslim. was bred from whitish cocoons in old dry- 

 wood of Birch (Betula), infested with the Cistelid, Mycetochares hinotata. 

 Imagos developed during the tirst week of May, Ithaca, !N^. Y. As a 

 considerable number of individuals of both parasite and Coleopteron 

 were bred, and no other insects were present in these twigs, I have no 

 hesitation in placing Mycetochares as the host of this parasite, espe- 

 cially since the type of the species was bred from Orchesia — a genus of 

 a very closely allied family — as recorded in an editorial article in 

 Insect Life, vol. iii, p. 57. 



Euphorus 'plila'otrihi Ashm. is an internal parasite of the adult of 

 Phlceotrihus frontalis, having been reared from pieces of the wood of 

 the White Mulberry {Morus alba) infested by this Scolytid. Although 

 only a single example of the parasite was obtained this rearing is of 

 much interest, for an examination of the galleries of the beetle resulted 

 in the discovery of an empty, whitish cocoon and a dead beetle which 

 had been parasitized, a ciicular hole near the end of its elytra showing 

 where the Hymenopteron had issued. This species is thus shown to 

 conform closely in habit to the congeneric sculjHtis Cr., a common 

 parasite of the adult MegiIJa macuhifa, which has been treated by Dr. 

 Eiley in vol. i of Insect Life (pp. 101, 338). It is probable, judging 

 by the size of the species under consideration compared with its host, 

 that the latter dies before or soon after the issuance of the parasite.

Romalotylus ohscnrus How. was reared by me from three different 

 species, representing as many genera of Coccinellidie. Three examples 

 were bred from larvae of Cocvinella 9-notata. The infested larva had 

 attached itself for pupation about September 20, and the adult para- 

 sites emerged in October, Spring Lake Beach, IST. J. A number of 

 these parasites were also bred from the larva oi Fsyllohora 30-maculata 

 taken with uuinfested larva? and the pupa^ and imagos of the same at 

 Ithaca, IS". Y., October 3 on the European Ash. Adult parasites issued 

 from April 24 to May 10 and earlier. Only a single parasite was bred 

 from each Coccinellid larva as far as could be ascertained. A third 

 rearing was from Myda puUata^ a ladybird confined almost exclusively 

 to pine trees and other Coniferjie. Eleven examples, an exceptionally 

 large number, were reared from a single larva, taken May 21, attached 

 to a pine needle. Each of these eleven parasites had, as in the first 

 case, issued from a separate hole in the body of the host. Other para- 

 sitized larvai were also seen. 



This insect was described from specimens bred by Mr. H. G. Hub- 

 bard from larvte supposed to have been those of Coccinella sanguinea 

 (Bulletin No. 5, Division of Entomology, p. 22). Subsequently Mr.
