Type coll. H. L,. Viereck. Co-type coll. Acad. Nat. Sci., 

 Philadelphia. Type, locality North Woodbury, Gloucester Co., 

 N. J., June 22 and August i, 1901 (H. L. V.). Two females, 

 one male. This species is maculated like P. albipcs Ashm., but 

 is evidently distinct from that species. 



Plenoculus atlanticus, n. sp. 



Clypeus narrow, broadly truncate with a blunt corner, front with a 

 longitudinal line running from the fore ocellus. Dorsulum uniformly 

 sculptured, metanotum transversely striate. Apical dorsal segment with 

 with a few indistinct punctures. 



^ Length 4.5 mm. -Clypeus with the truncation as broad as its length, 

 shining and sparsely puncttired. Front slightly convex, not distinctly im- 

 pressed laterally, very minutely and uniformly sculptured, opaque, a shin- 

 ing impressed line running from the anterior ocellus down on the face to 

 near the insertion of antennae, cheeks more shining almost similarly 

 sculptured. No part of the head thickly sericeous, the pubescence 

 heaviest on face ; excepting on cheeks, where it is silvery, the pubesence 

 is golden. First joint of the flagellum about as long as the second, man- 

 dibles internally with a distinct tooth near the middle. Dorsulum finely 

 uniformly sculptured with two parallel shining lines medially, not extend- 

 ing to the middle. A line starting before the middle laterally extending 

 almost to the posterior border, mesopleurae with a curved impressed line 

 anteriorly, microscopically, uniformly sculptured. Metanotum longitudi- 

 nally impressed medially, with tranaverse fine striae, some of which origi- 

 nate on the anterior border and radiate off to the sides, the small triangular 

 polished impression on the superior half of the metathoracic truncation 

 distinct, the base of the truncation and the metapleurae sculptured much 

 like mesopleurae. Second recurrent nervure received by the second 

 submarginal cell distinctly beyond the middle. Abdomen dull, apical 

 segments becoming shining, the apical segment with sparse ill defined 

 punctures. 



Black ; clypeus ochre yellow, mandibles, exceping brown apices, lemon 

 yellow, part of scape, anterior femora beneath, the apices of all the femora 

 and all tibiae and tarsi more or less tawny ochraceous.

Type, locality North Woodbury, Gloucester Co., N. J., June 

 13, 1901 (H. L,. V.). In the co-type the striae of metanotum 

 are almost entirely missing. This species is closely related 

 to P. davisii Fox, from which it can be distinguished by 

 the clypeus, the finer sculpture, and quite readily by the 

 coloration.
