PAEASITES REARED FROM EGGS OF GTPSY MOTH. H 



cocoon hidden among the egg-masses and so covered with wax as 

 probably to be inchstinguishable. 



Several species of Elachertines of this general type, including at 

 least one undescribed genus in addition to Atoposoma and Zagram- 

 mosoma, have been reared from Microlepidopterous larvae. The first 

 one that the writer ever saw was reared from Lithocolletis fitchella 

 in Washington in 1879. Others were reared from leaf-miners from 

 Florida, but none of these striking forms was described until Ash- 

 mead'* described the genus Hippocephalus for a species, multiline- 

 atus, reared by Mr. C. L. Marlatt from Lithocolletis ornatella. On 

 account of the preoccupation of the name FlippocepJialus, Ashmead, 

 in his monograph of the Chalcidoidea, changed the name to Zagram- 

 niosoma. Masi's type of Atoposoma (A. variegatum) fed in the 

 larval state exteriorly on a larva of the Lepidopter, (EcoplujUembius 

 neglectus. The present genus, Atoposomoidea, appears to be the first 

 Chalcidid of this markedly beautiful and peculiar facies to have been 

 reared from a Braconid cocoon, and we must assume from the great 

 numbers in which these rearings have been made that the habit is 

 normal for this species.

The type series of this beautiful little parasite was reared in Feb- 

 ruary, 1900, by A. Koebele from a scale insect of the genus TacJiardia 

 on an ornamental plant at Singapore, Straits Settlements. All of 

 the other species of the genus have been reared invariably from scale 

 insects and nothing else. A record of the issuance of P. javensis 

 from gipsy moth eggs is therefore open to doubt, and one's first im- 

 pression is that it must have come from some scale insect over wliich 

 a dispar egg-mass had been laid. Nevertheless, according to Mr. 

 Fiske, the single female submitted to the writer for determination 

 came from a dispar egg received from Professor Kuwana from near 

 Tokyo. The apparent great discrepancy between this statement 

 and the previous records renders it desirable to give an explicit state- 

 ment of the facts as observed by Mr. Fiske. From his original notes 

 it is found that December 9, 1908, a lot of 250 egg-masses of dispar, 

 collected in Tokyo November 5, 1908, by Professor Kuwana, was 

 received. One of these egg-masses was thin, with the hairy covering 

 badly weathered, and many of the eggs exposed. Critical examina-
