calif ornicum by Fowler; most likely his specimens belonged with 

 the transversumAike females with which he associated them. 



Anthidium incurvatum n. sp. 



c^. Length 12 mm. Black; clypeus, lateral face marks ending trun- 

 cately at lower level of insertion of antennae, mandibles except tips, two 

 large round spots on vertex behind tops of eyes, large L-shaped marks on 

 antero-lateral angles of mesoscutum which extend inward one-third across 

 the anterior margin of mesoscutum and backward over tegulae, front half 

 of tegulae or nearly that, tubercles, four spots on mesoscutellum, the outer 

 and slightly smaller pair of which are on the axillae, outer faces of basi- 

 tarsi, small spots on apices of last four tibiae, four spots on abdominal 

 tergite i, the inner pair of which are sometimes large and sagittate but 

 often very small or subobsolete, tergites 2-6 with bands which are some- 

 times all complete (in type), but often medially interrupted on 2, 3 or 6, 

 and always very deeply emarginate on anterior margins of 2-5 and me- 

 dially greatly attenuated and incised on anterior margin, and sometimes 

 lateral spots on pygidium above, yellow. Antennae deep black, joint 3 

 one and one-third as long as 4 in the shortest plane. Pubescence copious, 

 long and white on face, pleura, legs and sides and venter of abdomen, on 

 thorax above erect and pale ochreous. Hair on inner side of basitarsi 

 reddish, deeper red on terminal joints. Wings slightly darkened basally 

 and distinctly darkened beyond submarginals, nervures black. Outer lobes 

 of pygidium broad and with their tips produced and incurved as in cali- 

 f ornicum, only even more acutely so, the middle lobe narrow, slightly 

 curved, nearly as long as the outer lobes and continued across the tergite 

 as a median carina. Tergite 6 with long curved lateral spines. 



Type. — ^Ute creek, Costilla county, Colorado, on sage flats, 

 July 19, 1907 (H. S. Smith), ^. 



Paratypcs. — Type lot, 2 ^. 



Obviously allied to A. calif ornicum Cresson but differing in the 

 yellow tubercles, yellow marks on antero-lateral angles of meso- 

 scutum, yellow spots on mesoscutellum, etc.

 recorded it from New Mexico and Robertson recorded it from
