and tarsi light testaceous. Abdomen slender, the end blunt; discs of 

 all the segments finely punctured and inconspicuously lineolate, the 

 apical margins and the ventral side of the segments dark brown. 

 Pubescence rather scant, deep ochraceous on the vertex and dorsal 

 half of the thorax, and pale gray on the face, cheeks and legs. 



Hab. Garrison, New York, one $ (=type), nearly 7 mm. 

 long, (Eleth Cattell) ; two $ nearly 7 mm. long (Eleth Cattell) ; 

 Woods Hole, Massachusetts, one $ almost 7.5 mm. long, June, 

 (T. D. A. Cockerell). 



This species and the next seem more related to each other 

 than to any other species ; they probably belong to a group with 

 H. aquilae Ckll., and H. nymphaearum Rob., since they all have 

 plicae on the metapleura. The very rough mesonotum suggests 

 H. pilosus Sm., from which the short round face of H. cattdlac 

 distinguishes it. H. cattellae may be separated from H. 

 perpunctatus n. sp. by the entirely shiny abdomen, and the few, 

 simple plicae of the basal area of the metathorax. 



Halictus perpunctatus sp. nov. 



Female. Length about 6 to 6.5 mm. Head and thorax metallic, 

 blue-green, abdomen brown with more or less distinct, blue-green 

 metallic reflections, the margins of the segments brown shading to 

 pale testaceous on the edge. Face a very little longer than broad ; 

 clypeus produced, its lateral margins entirely free, the broad lower 

 margin shiny black, toothed along the edge; face finely and closely 

 punctured above the antennae, a little more coarsely and scatteringly 

 below, f rons and clypeus shiny ; cheeks rather full and shiny, although 

 finely punctured. Mesopleura with coarse scattered punctures of ir- 

 regular shape; slender plicae crossing the upper half of the meta- 

 pleura, becoming very weak and broken below the middle; mesonotum 

 opaque, rather coarsely and very closely punctured; median groove 

 well developed, parapsidal grooves faint. Basal area of the meta- 

 thorax almost as wide as the scutellum ; with a low, sharp rim ex- 

 tending well laterally; rugae strong and rather numerous, reticulate 

 near the middle. Tegulae bright brown. Wings hyaline; stigma and 

 nervures pale honey color, costal nervure darker. Legs black, shad- 

 ing to brown on the tarsi ; inner spur of the hind tibia with two 

 large and three rather abruptly, smaller, clavate teeth. Abdomen 

 stout; disc of the first segment very shiny, the few scattered punc- 

 tures very fine and shallow, disc of all the other segments with the 

 punctures fine, sharp and close together; segments 3 to 5 closely
