NO. 2332. VARIO US NEW SPECIES OF HYMENOPTERA—GJRA ULT. 191 



Male flagelliim filiform (club not seen), the funicle joints subquad- 

 rate, shorter than the pedicel. Sculpture (female) very fine scaliness, 

 the thorax with punctures like those of the frons. 



BLASTOTHRIX BRITTANICA, new epecies.J 



In Mayr's table to Encyrtus runs also to meges Walker and allies 

 but bears no punctures; to sericea Dalman but the antennae are 

 wholly concolorous as are the legs (the middle tibiae concolorous ex- 

 cept at each end). 



Females. — Length, 1.20 mm. Dark metallic green and densely 

 pin-punctate. Wings hyaline the venation dusky. Knees broadly, 

 tips of the tibiae and the tarsi dull yellow to white. Proximal half 

 of tegula silvery white. Propodeum and abdomen scaly. Scape 

 but moderately dilated ventrad, yet distinctl}^ so; pedicel nearly a 

 half longer than wide at apex, longer than any funicle joint; funicle 1 

 a little longer than wide, subequal to 2, 3 and 4 subequal, a half 

 more longer than wide, 5 and 6 subquadrate, widest. Club a little 

 over half the length of the funicle, wider than it, ovate. Second 

 tooth of mandibles broadly truncate. Marginal vein twice longer 

 than wide, a third or more shorter than the stigmal, the latter long 

 but somewhat shorter than the subelongate postmarginal, the latter 

 tapering. Axillae with a short carina between them. Cheeks 

 longer than the eyes, the frons moderateh^ broad. Male, the same 

 but the antennae paler, the club solid, longest, the scape short and 

 dilated, the pedicel globular, shortest; funicle joints as in male 

 Eurytoma, longer distad. In the male, the three distal veins of the 

 fore wing are subequal, the stigmal a little the longer. Hairless line 

 fore wing complete. Three pairs from Lecanium capreae, Cheshire, of 

 England, (A. D. Imms). 



Type. — Cat. No. 20853, U.S.N.M., two males, one female on a 

 tag, appendages on a slide. 



PARASTENOTERYS NIVEICLAVA GirauU. 



Parastenoterys niveiclava Girault, Chalc. Nova Marilandensis, II, 1917, p. 1. 



Fejnale. — ^Length, 1.00 mm. 



Dark metallic green, the scutellum bronze and lighter, the legs 

 (except the coxae) and the scape reddish yellow, the wings hj-aline, 

 the venation yellowish. Club snow-white except the dusky basal half 

 of the first joint. Body scaly, the abdomen subglabrous, the scutel- 

 lum densely, finely punctate, a double row of punctures on the 

 vertex, along each eye, the scutum and axillae with many, scattered 

 setigerous punctures. Axillae barely separated or not at all. Scu- 

 tellum nearly as hairy as the scutum, the hairs soft, prostrate or 



iThe description for this species was published by Imms (Quart. Journ. Micr. Sci., vol. 63, 1918, p. 

 295,341, 24 text figs.) but the name accredited to Girault. Since then Silvestri (Boll. S. Z. A. Portici 

 vol. 13, 1919, p. 164) has synonymized the name with Blastnthrix sericea (Dalmau).— S. A. Rohweb.
