THE CANADIAN ENTOMOLOGIST. 139 



The Platygaslerids, so far as we know, are parasitic only upon 

 Dipterous insects, and probably this species will be found to be a 

 hyperparasite upon a Dipteron infesting the scale insect. 



Family LXVII. — Encyrtice. 

 Genus Coccidencyrtus, Ashmead. 



(2) Coccidencyrtus flavus, new species. 



<j> . — Length, 0.8 mm. Golden yellow; legs yellowish white; 

 antennal club brown ; eyes brown-black. Wings hyaline, the marginal 

 vein punctiform, not longer than thick, the postmarginal scarcely longer 

 than the radius or stigmal vein ; the stigmal vein, although comparatively 

 short, is fully twice as long as the punctiform marginal vein and 

 terminates in a little knob. 



The flagellum is subclavate, the funicle 6-jointed, the joints sub- 

 moniliform, increasing in width and size to the club, the first three or four 

 joints being very small, narrower than the pedicel, the sixth about as wide 

 as the pedicel, the club stouter, cone-shaped and as long as, or a little 

 longer than, funicle joints 3 to 6 united. 



Type.— Cat. No. 5728, U. S. N. M. 



Hab. — Cape Colony, South Africa. 



Host. — Rhynch. : Dactylopius sp. on Gorse. (Chas P. Loundsbury.) 



Evidently the same thing, only slightly differently coloured, being 

 more of a brownish yellow, having the sutures of the thoracic sclerites, a 

 spot on the anterior part of the thorax and a band across the base of the 

 abdomen, dark brown, but otherwise agreeing structurally ; was bred by 

 Prof. Loundsbury from a Lichtensia sp. on Pittosporum. 



Family LXXI. — Eulophid.e. 



(3) Tetrastichus prospaltce, new species. 



$. — Length, 0.7 mm. Black (possibly polished, the specimens 

 being mounted on a slide in balsam, and the sculpture, if any, not being 

 noticeable) ; face anteriorly and the legs, except the hind femora, 

 apparently pale yellow ; hind femora brown. Wings hyaline, the teguhe 

 and veins pale yellowish ; the front wings, from base to the origin of the 

 marginal vein, are wholly hairless, beyond they are closely, finely hairy 

 and ciliate at margins ; the marginal vein is very slightly longer than the 

 subcostal, while the stigmal vein is much less than its length.
