The Bees of Nebraska. II. 



By MYRON H. SWENK and T. D. A. COCKERELL. 



FAMILY PANURGID^E (Concluded) 



Genus SPINOLIELLA. Ashmead. 



1. Spinoliella australior Cockerel!. 



Glen, Crawford and Warbonnet Canon, Sioux County, Ne- 

 braska, July 28 to August 17, common at flowers of Cleonic 

 serrnlata and occasionally on Solidago also. One would expect 

 to find S. scitula Cresson here also, but all the specimens as 

 yet captured are distinctly australior; the differences between 

 the two species, though not great, are very constant. 



2. Spinoliella helianthi n. sp. 



?. Length 6 mm.; clypeus (except for two large, separated, basal, 

 black spots), labrum, mandibles, supraclypeal area, dog's ear marks, 

 and lateral face marks including whole of sides of face up to level 

 of antennae and a little beyond along the orbits, bright yellow. Rest 

 of head shining black, the front coarsely, distinctly punctured, the 

 cheeks indistinctly so. Antennae black, the flagellum pale brown ex- 

 cept the basal joints above, which are blackish. Front with long, 

 erect, dense, gray pubescence, cheeks with similar but shorter and 

 thinner pubescence. Thorax black, dorsum punctured like the front, 

 clothed with long, gray hair, denser and paler on the pleura. Tegulae 

 shining brown. Wings hyaline, nervures brown. Abdomen black, 

 segment I with a complete, median, deep yellow band, 2 with widely 

 interrupted lateral bands, 3 and 4 with broad complete bands, fifth 

 segment largely yellow. Legs black, with all the tarsi and knees and 

 the anterior tibiae, except for a black spot above and below, yellow. 

 Legs and tip of abdomen with long, erect, whitish hair. 



Type: Warbonnet Canon, Sioux County, Nebraska, July 

 12, 1901, on Helianthus (M. Cary), $ . 



S. helianthi is not close to any described species. It runs in 

 the table in Trans. Am. Ent. Soc., XXV, p. 195 to 3\ zebrata, 

 which is a much larger and very different species. The deep 

 yellow marks' of abdomen and black spots on the clypeus will 

 serve to characterize the species. 



Genus CALLIOPSIS F. Smith, 

 i. Calliopsis andreniformis F. Smith. 



Lincoln, Omaha, West Point, Weeping Water, Cedar Bluffs, 

 and Cams, Nebraska, flying abundantly from May 31 to July
