the scape in the male. From A. emarginatum (Say), it is dis- 

 tinguishable by the deep ochreous color of the pubescence of the 

 thorax above and the dark colored scopa in the female and by the 

 yellow stripe on the scape and the more broadly rounded pygidial 

 lobes in the male. 



SPECIES FROM OUTSIDE NEBRASKA 

 Anthidium praedentatum trianguliferum n. subsp. 



$. Length lo mm. Belongs to the placiium group, the species of which 

 have the pygidial tergite yellow or mostly yellow. Agrees with Cresson's 

 description of the unique type of A. placitum from Nevada (Trans. Am. 

 Ent. Soc, VII, p. 206), except that there is no fuscous hair on mesonotum 

 and very little on vertex (the pubescence being all whitish, becoming 

 strongly tinged with ochreous on vertex), the median stripe on the clypeus 

 is attenuated below so as to form a triangle of black subequal to the yellow 

 triangles set off on either side, the band on the vertex is so broadly inter- 

 rupted as to be practically reduced to elongate cuneate lateral spots, the 

 tegulae have a yellow spot on the posterior margin, the axillae are mostly 

 yellow and are nearly confluent with the mesoscutellar lines, the yellow 

 bands on tergites 1-4 are narrowly interrupted medially, and the abdomen 

 is narrower, parallel-sided, and rather distinctly punctured. In the broadly 

 interrupted band on the vertex, the yellow-banded axillae, and the inter- 

 rupted bands on tergites 1-4, it agrees with A. praedentatum Ckll. (de- 

 scribed originally as a subspecies of A. blanditttm Cresson and later re^ 

 f erred to as a subspecies of A. placitum, but probably a distinct species), 

 from Boulder, Colorado (The Entomologist, XL, p. 99), but differs from 

 that form in the triangular, not W-shaped, black clypeal mark. In the 

 clypeal marking it agrees with the female of A. poudreum Titus (Proc. U. S. 

 Nat. Mus., XL, pp. 248-249), but the yellow lateral mesoscutal stripe is 

 angulated anteriorly and the femora have broad yellow stripes. From A. 

 hlanditum Cresson and A. blanditum pecosense Ckll., it differs in the dark 

 median band on the clypeus, that species having the clypeus yellow or 

 mostly yellow.

 (L. Bruner), ?. 



Anthidium hesperium n. sp. 



?. Length 9-10 mm. Form stout. Black; clypeus except a broad par- 

 allel-sided median band, triangular areas on sides of face extending up 

 to level of insertion of antennae, mandibles except tips, small round spots 

 on vertex behind eyes, large spots on front and hind margins of tegulae, 

 spot on wing bases, line over tegulae, tubercles, four spots on mesoscu-
