The larvae of the Sarcopliaga are deposited and the Aphae- 

 reUi oviposits in them the same day, the adults emerging from 

 the puparia which form after the larvae have buried them- 

 selves in the ground. Several individuals of the Aphaereta 

 emerge from a single puparium. 



Ashmead described muscae as without a longitudinal median 

 impressed line on hte occiput behind the ocelli, but in the form 

 found in the Hawaiian Islands such a line is present. 



The European A. minor is described as having no sulcus 

 at the base of the scutellum. It is singular that the South 

 African species should resemble the ]S'orth American species so 

 much more slosely than the European. 



In this connection it may be well to record definitely that 

 A. muscae in the Hawaiian Islands attacks Sarcopliaga palli- 

 nervis Thompson, a species known only as breeding is cow dung. 

 It has been repeatedly bred from this host by Mr. Swezey and 

 Mr, Timberlake. 



CYNIPIDAE, Eucoilinae. 



9. Bothrochacis stercoraria n. sp. 



5 . Black, highly polished and shining ; mandibles in the middle, an- 

 tennae, legs and abdomen dark rufous ; the wings brownish yellow fading 

 to hyaline in the radial cell and below, apically. Antennae T3-jointed, the 

 seven apical joints larger, moniliform; third joint longer than fourth, 

 twice as long as broad ; pedicel globular ; scape pyriform. 



Pronotum truncate in front ; collar costate, the carina emarginate 

 in the middle ; three or four longitudinal radiating striae in the superior 

 angle of the side of the pronotum where it joins the collar carina; below 

 this is a dense brush of fulvous hairs as in Encoila; mesopleura as in 

 Eucoila ; mesonotum entirely without furrows, ridges or punctures; fovea 

 of the base of the scutellum divided by the carina at the base of the 

 cupuliferous elevation, the cupule on the posterior face of the elevation; 

 back of the fovea is a small oval shallow impression on either side. 

 Second tergite with a ring of dense pubescence at base. 



Wings with median, transverse median, basal and radial veins fully 

 developed; brown; second abscissa of radius straight, at right angles with 

 the first ; from the angle of the radius obscure vestiges of veins extend 

 in a curve apically and basally. The radial cell is open about its apical 

 two-thirds on the wing margin, wings entirely without pubescence, apical 

 margin entire and rounded. Length 3 -.5 mm., wing 3 mm.
