ON t^OME KEAPvEl) PAllxVSITIC llYMENOPTEKOrS INSECTSFROM CEYLON. Bj' L. O. Howard, Ph. 1).Honorary Curator of Insects,andWm. H. Ashmead,Custodian of the Uiimtnoptera. Ml?. E. ERNE8T Green, of Punduloya, Ceylon, has lon^- l)een study-ing the Coccidii' of that interesting region, and has in preparation alarge work in parts entitled The Coccid;e of Ceylon.' In the course ofhis studies of the Coccidie, he has reared certain hymeuopterous para-sites from them. These he has sent to the U. S. National ^Museum fornames, sending with them a few parasites of lei)idopterous larva* whichhe has incidentally reared.The parasitic Hymenoptera of Ceylon are not well known. A fewspecies have been described by Walker and a number of others byMotschulsky. It is not surprising, therefore, that the majority ofthe species sent by Mr. Green proved to be new, and the material isof additional interest for the reason that in every case the parasite isassociated with its host insect. The most striking feature of the send-ing is the number of parasites reared from one of the lac insects ? Tavli-ardia albizziw. It will be interesting to state that Mr. Green has foundseveral other insects associated with this economically imi)ortant Coccid,among them a Phl(eothrii>s which feeds on the excretion of tlie bark-louse, and a Tineid larva which preys upon the Coccid itself.Of the insects here reported upon, Dr. Howard has studied the Chal-cidida' and Mymaridie and Mr. Ashmead the Ichneumonida- andBracouidje.

It belongs to Wesmael's division Cyclostomi, and on accountof the immargined occiput is allied to the subfamilies Braconina^ andExothecina^, but on account of the shortness of the submedian cell,which readily distinguishes the genus from all others yet described, itwill not fit into either of these; the former has the submedian andmedian cells et^ual, while in the latter the submedian cell is the longer.It may therefore represent a new subfamily if the length of these cellsis still to be considered of primary importance.At present I prefer to place it in the subfamily Braconinte, sinceI am inclined to believe that too much importance has been given tothe length of the basal cells.APHRASTOBRACON FLAVIPENNIS, new species (Ashmead). ^[aJe.?Length, 4,5 mm.
