SOME MAINE SPECIES OF HALICTUS. 



BY JOHN H. LOVELL, WALDOBORO, MAINE. 



This paper continues the enumeration of the species of Haliclus 

 found in Maine, begun in the Canadian Entomologist for February, 

 1905, page 40. 



Halidus similis, Snnith, J $ . — A very common species in this 

 locality, taken from June 19th to August 24th. It visits a great variety 

 of flowers, as the blackberry. Iris versicolor, Sagittaria latifolia, Aralia 

 hispida, Cornus Canadensis, and the thistles and goldenrods. Professor 

 Cockerell, who has examined Smith's type in the British Museum, states 

 that the Maine specimens agree with it in all the more important charac- 

 ters. It is a broad, thickset bee, with the mesothorax closely punctured ; 

 the metathorax is sharply truncate, with the basal area not well defined, 

 and coarsely sculptured or ridged ; the first segment of the abdomen is 

 distinctly punctured, and there are lateral fascias, sometimes entire, on 

 the second and third segments. It differs from Smith's type in the lighter 

 brown colour of the stigma ; and the apical fimbria, which, in the type 

 light fulvous, is brown in the Maine form. 



Balictus pectoralis, Smith, ? $. — Collected on the blackberry, rose, 

 goldenrod, etc. The specimens are typical, not very common. 



Halidus Foxii^ Robt., $ $ . — Taken on Diervilla trifida and the 

 wild rose. Agrees with authentic material of If. Foxii in the produced 

 clypeus, absence of hair patches at base of abdominal segments, and in the 

 sculpturing of the metathoracic area. The differences are slight. 



Halidus divergens, n. sp., 9- — This species is very closely allied to 

 H. quadrimaculatus, Robt.; but the head in that species is nearly round 

 viewed from in front, while in H. divergens it is decidedly longer than 

 broad ; the wings are darker and the nervures a dark brown. Length, 6 

 mm. In other characters it agrees with H. quadrimaculatus ; the meso- 

 thorax is finely punctured ; the metathorax is rounded, with numerous 

 raised lines not extending to the apex ; and at the extreme sides of 

 abdominal segments 2 and 3 there are patches of white pubescence. 



Halidus nelumbonis, Robt., $ . — I have taken this species only on the 

 flowers of Nymph?ea (Nuphar) advena, not common. It agrees with the 

 description, and was also a few years ago determined for me by Dr. 

 Ashmead. 



Halidus pilosus, Smith, 9 (^ . — A common species. Collected on the 

 flowers of Salix Bebbiana, Clematis Virginiana, and Epilobium angusti- 

 folium. 



August, 1903
