Of the species given above, only nymphalis is known to me. 

 In creberrimus and inconspicuus the color of the anterior mar- 

 gin of the clypeus is not given, as they are included above. 



Halictus mariuus n. sp. ?. Green, inclining to olive, with a very 

 slight brassy reflection, clothed with abundant white pubescence, long 

 and conspicuously plumose on the sides of face, pleura, scutellum, post- 

 scutellum, metathorax, base of first abdominal segment and lateral mar- 

 gins of other segments ; head closely and moderately coarsely punctate, 

 facial quadrangle distinctly longer than wide ; clypeus with large sparse 

 punctures, apex smooth, purplish-black ; antennae black, the flagellum 

 dull ferruginous beneath ; mesothorax finely roughened, finely and 

 closely punctate, scutellum with two smooth spots on disc ; mesopleura 

 rather coarsely punctate, metapleura finely roughened ; medial and par- 

 apsidal grooves apparent but not very distinct ; base of metathorax 

 finely, strongly longitudinally rugose to apex, not enclosed, truncation 

 finely roughened, rounded at top ; legs dark brown, femora with aeneous 

 reflection, pubescence white ; inner hind spur with four long teeth, the 

 last rather short ; wings hyaline, splendidly iridescent, nervures and 

 stigma very light honey color ; tegulae dark, pubescent, very large and 

 pointed behind as in tegularis, punctate all over ; abdomen finely trans- 

 versely lineolate, finely, sparsely punctate, the first segment with finer, 

 very sparse subobsolete punctures ; apical margins of segments 1-2 

 rather narrowly testaceous, of 3-4 broadly testaceo-hyaline ; all abdo- 

 men, except disks of segments i and 2, rather thinly covered with whitish 

 plumose, sub-appressed pubescence, more abundant toward apex ; ven- 

 ter dark, apical margins of segments lighter. Length 6-7 mm. 



unknown. 



Four specimens from Ocean City, N. J., June 19, '01 (Vier- 

 eck, coll.) 



' Swept from grass Sdrpus, Ammophila, etc., growing along 

 the strand just within the beach, and constituting the first 

 zone of plant life from the ocean maybe they they were fly- 

 ing up from their nests in the sand." (Viereck in litt.) 



Received from Mr. H. L,. Viereck, who remarked : "Allied 

 to pilosus Sm., but distinct by whitish pubescence and larger, 

 less crowded punctures on dorsulum." It is also distinguished 

 by the tegulse, which place it in the tcgularis group, but the 

 large size easily separates it from those species. Nymphcearum 

 also has the tegulae punctate, but they are rounded behind ; 

 the metathorax is very coarsely rugose, and the abdomen 

 black, easily separating it from marinus.
