on anterior margin, and large spots on tergite 6 which are irregularly 

 emarginate externally, deep yellow. Clypeus with two strong lateral teeth 

 on each side of the apical margin between which the margin is transverse 

 and smooth. Inner faces of tarsi with reddish hair, otherwise pubescence 

 wholly whitish. Ventral scopa white. Pygidium broadly rounded with 

 weak lateral teeth or angulations. Wings slightly darkened, nervures dark 

 brown. 



Type. — Pacific Grove, California, July, 1894, $. 



Allied to A. hesperium and A. h. dentipygum, just described, 

 but differing in smaller size, yellow clypeus without a median 

 black area, transverse intradental clypeal margin, yellow lines on 

 anterior margin of mesoscutum, narrower yellow tibial stripes, 

 lack of yellow stripe on hind femora, less extensively yellow 

 pygidium, etc. It is of the same size as A. montivagum Cresson, 

 but differs at once in the mostly yellow clypeus, the band on 

 tergite i divided into four spots, the deeper yellow color of the 

 ornaments, etc. 



Anthidium sagittipictum n. sp. 



$. Length 7 mm. Black; two spots on sides of clypeus which are nearly 

 confluent with two spots on lower corners of face, a sagittate spot in the 

 trapezoidal median dark clypeal area, mandibles except tips, elongate marks 

 on vertex which extend inward until opposite outer ocelli, spot on tegulae 

 in front, narrow line over tegulae, tubercles, two elongate spots on meso- 

 scutellum, basal yellow stripes on the outer faces of the tibiae which ex- 

 tend nearly the entire length of the joint on anterior pair, four spots on 

 abdominal tergite i, medially interrupted bands on tergites 2-6 which are 

 broadly emarginate on anterior margin on 2-4 and involve most of the 

 tergite on 6, yellow. Sides of apical margin of clypeus with a pair of 

 prominent teeth, the margin between them concave and even. Head and 

 thorax dull, roughened by an exceedingly close, fine puncturation. Pubes- 

 cence all pale, dense on face above antennae, on pleura and sides of abdo- 

 men, very sparse and short on mesoscutum. Hair of legs pale except the 

 pale reddish hair on tarsi within. Ventral scopa white. Pygidium broadly 

 rounded or subtruncate on apical margin and with a very feeble tooth or 

 angulation on each' side. Wings hyahne, nervures brown. 



Type. — Pullman, Washington (C. V. Piper), $. (Washing- 

 ton Exp. Sta. No. 127.) 



A distinct little species, scarcely needing comparison with its 

 congeners of like size.
