Descbiption of Femat.e and Male of Lesticocampa leucopus (Labva Unknown) : 



Female. — Proboscis long, slender, uniform, labellse rounded, with minute 

 outstanding setse; vestiture brownish black. Palpi moderate, one-fifth as long 

 as proboscis, uniform black, with a blue reflection, a few outstanding setae. 

 Antiennas moderate, basal joints about four times as long as wide, the terminal 

 ones increasingly longer, rugose, pilose, black; tori subspherical, with a cup- 

 shaped apical excavation, luteous, shaded with blackish; hairs of whorls long, 

 sparse, moderate, black. Clypeus broad, rounded, blackish brown, nude, with a 

 slight pruinosity. Eyes black, contiguous at the vertex. Occiput smoothly 

 clothed with flat appressed scales, black with metallic-blue reflection, silvery in 

 some lights, a row of erect forked black scales along the posterior margin, a row 

 of setae along margins of eyes, two coarse bristles at vertex. 



Prothoracie lobes large, elliptical, remote dorsally, luteous, sparsely clothed 

 with small silvery scales, a row of setae along anterior margin. Mesonotum 

 brown, clothed with narrowly elliptical scales, grayish brown, with a submetallic- 

 purplish reflection, a row of bristles around edges of disk and ante-scutellar 

 region. Scutellum trilobate, vestiture of broad, flat metallic blue and green 

 scales, each lobe with a tuft of brown bristles. Postnotum elliptical, prominent, 

 with a median carina, dark brown, with a tuft of small setae posteriorly. Pleurae 

 dark brown in the middle, coxae luteous, clothed with patches of silvery-white 

 scales. 



Abdomen subcylindrical, with many stout terminal bristles ; dorsal vestiture 

 black with a blue metallic reflection ; venter golden yellow, the colors separated 

 on the sides in a line indented on fifth, sixth, and seventh segments. 



Wings rather narrow, slightly infuscated; petiole of second marginal cell 

 one-half as long as its cell, that of second posterior cell slightly shorter than its 

 cell ; basal cross- vein nearly its own length beyond anterior cross-vein ; out- 

 standing scales of veins narrowly elliptical, brown, with green reflection. Hal- 

 teres black, brown at the base. 



Legs long, slender, black with purple metallic reflection, the femora with 

 brassy reflection beneath nearly to apices; spines on hind tibiae large; vestiture 

 somewhat roughened ; hind legs with apical portion of tibia and basal portion of 

 first tarsal joint ciliate, apical third of fourth tarsal and all of the fifth joint 

 white; mid tarsi with last three joints and apex of the second with yellowish- 

 silvery sheen, white below. Claw formula, 0.0-0.0-0.0. 



Length : Body about 5 mm. ; wing 4.5 mm. 



Maie. — Antennae with last two joints long and slender, rugose, black, with 

 long pile; the other joints about four times as long as wide, with very slightly 

 thickened rings at the insertions of the hair-whorls, blackish, slightly paler 

 before the rinp ; hairs long, moderate, not plumose, black, a secondary whorl 

 of small hairs at middles of joints. Proboscis long and slender, black. Palpi 

 about two-thirds as long as the proboscis, very slender, uniform, the last two 

 joints with a few short coarse outstanding setag. Coloration as in the female. 

 Wings slightly narrower than in the female, the stems of the fork-cells longer. 

 Abdomen long, slender, expanded at tip, last segment and genitalia blue-
