with all the abdominal bands divided into spots as in A. 

 macnlosum ; pubescence white, some blackish on scutellnm, 

 and vertex, and especially just behind ocelli ; clypeus bright 

 lemon yellow, not spotted, not at all obscured by hair, its 

 narrow lower edge black ; lateral face-marks, mandibles ex- 

 cept iipes, and small spot above each eye, yellow; first and 

 second mandibular teeth broad and sharply pointed : an- 

 tennae entirely black ; thorax all black except two small 

 yellow marks on scutellum ; tegulae with a large yellow spot 

 in front and a small one behind ; wings not very dark ; legs 

 black, with the basal joints of the middle and hind tarsi 

 cream-color (but basal joint of anterior tarsus is black) ; ab- 

 dominal segments with thin marginal fringes of black hair ; 

 sixth segment with four spots like the others, seventh ail 

 black ; lateral apical processes long and narrow ; venter of 

 abdomen black. 



Hab. — Pecos, New Mexico, at flowers of Lupiniis near Harri- 

 son 's store, June 30, 1903, collected by W. P. Cockerell. By 

 the structure of the last two dorsal abdominal segments, 

 this is closely related to A. banningense; but it is smaller 

 and differs in several jjarticulars. 



Anthidium tricuspidum, Provancher. 



Los Angeles, Calif., three collected by Dr. Davidson. Provan- 

 cher 's description, is incomplete, but as his material was 

 from the same locality, and the rather peculiar bright yellow 

 pattern of the abdomen agrees, I assume that I have the in- 

 sect he described. The ventral surface of the abdomen is 

 light ferruginous. 



Anthidinm californicum, Cresson. 



Los Angeles, Calif., five collected by Dr. Davidson. In these 

 specimens the hair on vertex and thorax above is white, not 

 dull yellow. I have not seen authentic material of A. cali- 

 fornicum, but the Los Angeles insect fits the description so 

 nearly that I assume it to be the same. 

 Anthidium palmarum, n. sp. 



Male; length about 9 mm.; pubescence Avhite, dense on face, 

 covering clypeus : clypeus and very small lateral face-marks 

 (separated from orbital margin), mandibles except tips, and 

 small spots above eyes, light yellow ; mandibles with first 

 and second teeth acute ; antennae entirely black ; thorax all 

 black except an interrupted yellow line on scutellum ; teg- 

 idae a warm red; wings rather clear; legs black, marked 

 with light yellow and ferruginous, the lighter colors includ- 

 ing the knees, stripes on anterior and middle tibiae, and 

 spots at base and apex of hind tibiae, the last also being red- 

 dish behind; basal joint of tarsi yellow, the other joint light
