ART. 2. CHALCID-FLY GENUS CHRYSOPLATYCERUS TIMBERLAKE. 3 



short, somewhat wider than long and as thick as the scape; flagel- 

 lum much thicker than the pedicel or scape, slightly tapering toward 

 the apex, compressed so that the funicle joints are narrowly oval in 

 cross section; funicle six-jointed, each joint in broadside view about 

 one-half wider than long and each deeply cupped at both ends with 

 a long stout connecting stalk as seen in transparent slide mounts; 

 club solid, narrowly oval, truncate at base and pointed at apex, as 

 long as the fifth plus sixth and one-half of the fourth funicle joints 

 combined and slightly narrower than the preceding joint; scape 

 and pedicel with coarsely reticulate surface and provided with a 

 few very short inconspicuous bristly hairs; flagellum clothed with 

 similar somewhat liner hairs at the base, but these gradually de- 

 crease in size and prominence towards the apex where they are 

 visible only under high magnification; flagellum also provided with 

 Aery numerous linear projecting sensoria, producing a fringe of 

 short spiny points around the tips of the joints and imparting a 

 13eculiar rough appearance to the surface of the joints. 



Mandibles about as in the female, small, slender, bidentate at apex 

 with the inner or upper tooth much longer than the other. Maxillary 

 palpi four-jointed, the third joint shortest, the fourth somewhat 

 longer than the preceding joints combined ; labial palpi short and two- 

 jointed. 



Thorax robust and strongly convex above from side to side; the 

 pronotum short and strongly arcuate; mesoscutum about twice as 

 wide as long or a little less; axillae short, transverse meeting medially 

 and either almost perfectly depressed or somewhat elevated with a 

 slight indication of a transverse median carina; scutellum more or 

 less distinctly shorter than the mesoscutum, convex, well elevated and 

 strongly declivous at the sides, the apex well rounded and without 

 a fascicle of hairs ; propodeum very short and transverse. Abdomen 

 small, strongly depressed, triangular in shape with the corners 

 rounded off, and a little longer than half the thorax ; vibrissal plates 

 situated on the lateral margins a little before the middle, the vi- 

 brissae inconspicuous but reaching nearly to the apex. 



Legs moderately long and slender, showing no marked peculiari- 

 ties, the middle tarsi only slightly thicker than the hind pair. Wings 

 shorter and proportionally wider than in the female, entirely hyaline, 

 the discal and marginal ciliation about normal for the family ; mar- 

 ginal vein about two or three times as long as thick, the stigmal very 

 much shorter than in the female, straight, forming an acute angle 

 with the postmarginal and reaching to the middle of the wing- 

 length; postmarginal indistinct distad but at least a little longer 

 than the stigmal. 



Face smooth and polished especially in the scrobes, cheeks finely 

 reticuhite, frontovertex finely rugosely wrinkled and with numerous
