[Mar. 
Cerceris (Apiratrix) eriogoni V. & C. 
Viereck and Cockerell, Jour. N. Y. Ent. Soc., 12: 139, 
1904. 
Two from Tempe, 31 July, and 2 August (Bequaert). 
Cerceris (Apiratrix) acanthopJiila Ckll. 
Cockerell, Entom., 1897, 135. 
Several from Arizona, Tempe, August 1 and 2 (Be- 
quaert) ; August 5 (Wheeler) ; Tucson, July (Bequaert) ; 
Tucson, September 1-5 (Carpenter). Two females, 4 
August, from Tempe, agree with the description of C. 
chilopsidis Vier. & Ckll. and are, I believe, the female of 
acanthophila. 
Cerceris (Apiratrix) vierecki sp. nov. 
Female. Black. Face with a large pale yellowish spot 
on middle lobe of clypeus, a spot on outer side of each lat- 
eral lobe, a supraclypeal spot, and an elongate spot each 
side by eye. This leaves on each side a black streak be- 
tween the supra-clypeal mark and the eye-spot running 
down on the lateral lobe. Basal joint of antennae pale 
beneath, also most of the mandibles, and a small spot be- 
hind each eye ; most of the antennae pale below and brown 
above. Pronotum with a spot each side, tegulae, spot 
each side on scutellum, line on postscutellum, all yellow- 
ish ; sometimes a spot below tegulae. 
Abdomen with a narrow apical band on the first seg- 
ment, a broad band on the second, broadly emarginate in 
front; third and fourth segments with a more broadly 
emarginate band, very narrow in the middle ; fifth with 
a narrow apical band, all yellowish; venter unspotted. 
Legs very pale, the femora largely black, front and mid 
pairs with apical fifth pale; hind tibiae with large black 
spot over apical half, and the tarsi (except basitarsi) 
brown. 
Wings faintly infumate, stigma brown, and a broad 
brown streak beyond. Body densely and rather coarsely 
punctate. Hair on face pale and very short, that on ver- 
tex and thorax longer and darker ; propodeum and basal 
segment with long white hair, rest of abdomen hardly 
hairy above, and few hairs in the ventral bands.
