POLYGNOTUS VERNALIS. new species. 



Female. — Length about 1.36 mm.; black and shining; front, vor- 

 tex, occiput, and cheeks transversely rugulosc and bare; mandibles 

 fusco-testaceous, a few long, scattered, whitish hairs on clypeus and 

 mandibles; eyes black; antennae lO-jointcd, fusco-piceous; scape 

 about as long as the four apical joints, longitudinally ruguloso, with 

 a few scattered whitish hairs; pedicel oblong globose, nearly as long 

 as first and second joints of the flagellum, pubescence sparse; first 

 and second joints of flagellum cylindrical, closely united, narrowest of 

 all joints, pubescence sparse; remaining joints granoso, rounded at 

 base and truncate at apex, apical joint longest of all; third and 

 fourth joints subequal, shortest of all, pubescence sparse; joints 5, 6, 

 7 thickest of all, rather densely pubescent andforming the club; pro- 

 notum shining, bare, reticulose, mesonotum shining, bare, indis- 

 tinctly aciculated longitudinally; scutcllum convex, smooth and 

 polished, distinctly margined, very faintly aciculated, and sparsely 

 pubescent, foveae at base widened laterally, narrowed medially; 

 parapsidal furrows very indistinct; propleurae shining and trans- 

 versely aciculated; mesopleura smooth and polished with transverse 

 curved aciculations dorsally; metapleura shining with dense whitish 

 pubescence; propodeum with two broad, rugose, median carinae and 

 a transversely striated knob at the apex, with long whitish pubescence 

 except on the knob and between the carinae; lateral carinae distinct; 

 petiole dorsally sulcate, its base flared especially dorsally to receive 

 knob on propodeum, densely pubescent except in sulcus; abdomen 

 ovate, smooth and highly polished, second segment very long, with 

 two shallow, dorsal concave areas at the base, base hairy; four re- 

 maining segments very short, a fringe of fine hairs on apex; coxa^ 

 black, trochanters fusco-piceous, femora black, tibiae black except 

 anterior tibiae which are fusco-piceous at base and apex, tarsi dark 

 testaceous on middle and posterior legs, a little lighter on the anterior 

 legs, all apical tarsal joints black; all tibiae and tarsi with white 

 pubescence; all femora and tibiae aciculated; wings hyaline, very 

 long, about two and a half times as long as the abdomen. 



Allotype. — Essentially the same as the type; second joint of flagel- 

 lum dilated; apex of abdomen not quite so pointed as in female; all 

 tarsi fusco-piceous. Antennae 10-jointed. Length, 1.04 mm. 



This species may be easily distinguished from Polyjnotus hiemalls 

 Forbes by the transversely rugulose head, the long wings, long, slender 

 legs and the body g-3n:)rally of leas robust form.
