FOUR NEW SPECIES OF HALICTUS FROM MAINE. 



BY JOHN H. LOVELL, WALDOBORO, MAINE. 



Halidus hortensis, n. sp. ? . — Length, 5 mm. Head and thorax 

 green, abdomen black, with the apical margins of the segments brown. 

 Head nearly as broad as long, face finely and densely punctured, thinly 

 clothed with a short white pubescence ; mandibles bidentate, rufous at 

 tips ; antennas black, pubescent, flagellum with minute appressed hairs, 

 brownish beneath. Mesothorax nearly bare, finely and sparsely punc- 

 tured ; disc of metathorax rounded or somewhat triangular, evenly and 

 finely rugulose or roughened. Wings hyaline, iridescent, nervures and 



stigma testaceous, tegulse testaceous, pubescent, impunctate. Eegs 

 brown-black, tarsi ferruginous, hind spur with four long teeth. Abdomen 

 impunctate, or with a few very fine punctures, the discs of the first and 

 second segments bare and shining, the apical segments thinly clothed with 

 a short white appressed pubescence. 



I have taken this bee in my garden on the flowers of the rhubarb, 

 blackberry, plum and rose. It is the smallest species of Halictus with 

 which I am acquainted in this locality. 



HalicUis versans, n. sp. $ . — Length, 6 to 7 mm. Head and 

 thorax dark green, abdomen oval or elliptical, black. Head broad, face 

 closely and finely punctured, clypeus dark purple, coarsely and sparsely 

 punctured, fringed with ferruginous hairs ; mandibles rufous at tips ; 

 antennae black, flagellum slightly testaceous beneath. Mesothorax densely 

 and finely punctured ; disc of metathorax rounded, with fine radiating 

 raised lines not extending to posterior margin ; truncation with a medial 

 fissure. Wings fuscous, stigma and nervures reddish-brown, tegulse black 

 with a piceous spot. Abdomen black, nearly bare, shining, a patch of 

 white pubescence at base of second and third segments, apical segments 

 very thinly and unevenly clothed with a whitish pubescence. 



^ . — Length, 6 mm. Like the female, the coloration is unusually 

 dark ; antennae testaceous beneath ; disc of metathorax rougher, with a 

 more or less salient rim. Two males taken on Solidago are referred to 

 this species. 



The female is described from specimens taken on Epilobium cmgus- 

 tifolium ; it has also been found on Solidago and other flowers. The 

 head and thorax are a. very dark green, the abdomen is remarkably regular 



February, 1905.
