from any known Chalcid. Abdomen somewhat sharply pointed and ending in a 
rather Jong ovipositor. Wings well rounded and strongly ciliated. Cox almost 
touching. 
In the Annual Report of the U. S. Department of Agriculture for 
1880 (p. 371), we called attention to this remarkable insect and stated 
that Mr. Ashmead was probably in error in locating the “ anomalous 
five-lobed appendage ” upon the hind legs instead of upon the middle 
legs, since it is probably homologous with the apical spur of the middle 
tibia so strongly developed in the Aphelinine and Encyrtine. 
Subsequent rearings of specimens from Mytilaspis gloverti and Aspid- 
iotus cydonie trom Florida, from an Aleyrodes on oak from California, 
by Mr. Coquillett, and from dspidiotus aurantii by the same gentle- 
man, as well as the deposit of one of Mr. Ashmead’s types in the col- 
lection of the U.S. National Museum, have enabled us to make a careful

study of this peculiar genus. It differs so markedly from all other 
known Chaleididze that it must be placed in a subfamily by itself, and 
we therefore propose for it the subfamily name Signiphorine. Several 
important points in the structure of the insect were not made out by 
Mr. Ashmead, and with more abundant material at our disposal we 
have drawn up a somewhat closer description of the genus and have 
characterized the subfamily, adding a description of the new species 
reared by Mr. Coquillett from the Red Scale.

Tarsi 5-jointed. Apical spur of middle tibia long and with several long spines on 
inner edge. Pronotum reaching nearly to tegule. Mesoscutum entire. Mesoscutellum 
represented by a narrow transverse band. Mesopleura short, sharply divided from 
metapleura. Metascutum with a differentiated triangular central sclerite, resembling 
the normal mesoscutellum. Antenne at most 8 jointed. Ovipositor cleft of female 
abdomen extending back to 3d segment.
