The larvae of the Sarcopltaga are deposited and the Aphae- 

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

 the pnparia which form after the larvae have buried them- 

 selves in the ground. Several individuals of the ApJiaereta 

 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 ^4. minor is described as having no sulcus 

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

 African species should resemble the ISTorth 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 Sarcophaga palli- 

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

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

 Mr. Timberlake. 



CYNIPIDAE, Eucoilinae. 



9. Bothrochacis stercoraria n. sp. 



$. 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 carin i 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 Eticoila; 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 nmi.
