HYMEXOPTEROUS PAKASITES. 1887 



Chalcis robusta Cresson. 



Black, clothed with a short, golden-yollow pubescence ; head broader than the pro- 

 thorax, the face, cheeks and occiput densel}' clothed with golden pubescence. Thorax 

 closely and rather deeplj' punctured, opaque; scutellum somewhat produced behind, 

 carinate at tip which is densely clotlied with golden pubescence, as well as the extreme 

 sides near the base ; metathorax roughly rugose ; tegulae bright yellow. Wings 

 faintly tinged with pale fuscous. Legs, excepting the coxae, bright yellow ; po.sterior 

 coxae robust, polished; their femora much swollen, black within except near the tip, 

 above and on the outside a large, oblique, black spot not reaching the upper margin, 

 but confluent beneath with the black of the inside; in one specimen this spot is entire 

 and not confluent beneath with the black of the inside, and the apical third within is 

 yellow; lower margin armed with a row of nine or ten small, obtuse black teeth and a 

 large obtuse one near the base; their tibiae curved, acute a t tips ; tarsi black at tips. 

 Abdomen subsessile, robust, convex, ovate, sometimes faintly compressed and pointed 

 at tip, smooth and polished, and the posterior margins of tlie apical segments more or 

 less fringed with yellowish pubescence. Length, 6 mm. to 8 mm. ; expanse of wings, 

 10-12 mm. (After Cresson.) 



This large and handsome chalcid has been reared by Mr. H. G. Hub- 

 bard at Crescent City, Fla., from the chrysalis of Heraclides cresphontes, 

 from which it issued through a large hole in the thorax. It was originally 

 described by Mr. Cresson from Cuba. 



Genus ENCYRTUS Dalman. 



Female. — Antennae U-jointed, inserted not far from the border of the mouth, modei-- 

 ately thick, and, with the exception of the scape, very seldom compressed; the scape 

 is often strongly broadened; the club is rounded, or with a slight oblique truncation 

 at tip. The facial impression is rather large and often quite deep. The mesouotum is 

 transversely arched, shagreened, and more or less lustrous; the scutellum shows a 

 different sculpture. The wings are always developed and ciliated ; the marginal vein is 

 present, seldom very short j the stigmal is moderately long. The ovipositor is not so 

 long as half the abdomen. 



Male. — The flagellar joints are slightly or not at all compressed, and covered equally 

 (not in half whorls) with hairs. 



Encyrtus montinus Packard. Fl. 89, fig. 4. 



Female. — Scape of antennae somewhat broadened below near tip ; pedicel cylindri- 

 cal, twice as long as broad ; first f unicle joint longer than broad ; succeeding joints in- 

 creasing very slightly in width but not increasing in length ; club nearly as long as 

 preceding three funicle joints together, ovate, but little broader than sixth fnnicle 

 joint. Fore wings cloudy, with a single, broad, clear band extending across the wing 

 from just beyond the stigma to posterior border, curving .slightly outwards ; an oblique, 

 hairless line also extends from the stigma across towards base of wing, and the course 

 of one of the spurious veins is seen extending from the hairless line to the hyaline 

 band. The mesonotum is very finely shagreened and is also covered with sparse, 

 large punctures. The general color above is light metallic green; the head, prono- 

 tum, tegulae and tip of abdomen dull yellow; the whole body below and at sides dull 

 yellow or testaceous ; legs yellow, the hind thighs somewhat dusky above; antennal 

 scape testaceous, pedicel and first four funicle joints yellowish brown with dark hairs, 

 funicle joints five and six white with white hairs, club black with black hairs. Length, 

 2 mm. ; expanse, i mm. 



This description is drawn up from Mr. Sanborn's original specimen, 

 which is a female, however, and not a male as Dr. Packard supposed, and 

 from a captured female received from Mr. Scudder.
