ant, as Polycrgus lucidiis (Wheeler, 'loa, p. 482; Tanquary, '11, 

 p. 302). 



MUTILLID^ 



Sphccrophthahna sp. Velvet Ant. 



This wasp was taken on the bare footpath at the margin of the 

 Bates upland woods (near Sta. IV, a) Aug. 23 (No. 151). It is prob- 

 ably parasitic in the nests of bees. 



Myzinid^ 



Myzinc scxcincta Fabr. 



This black-and-yellow-banded wasp was very abundant on flowers. 

 It was taken Aug. 8 (Sta. I, ^) on flowers of Asclepias incarnata (No. 

 i) and from Pyciiaiithcnium flexnosiim (No. 6) ; from the flowers of 

 goldenrod, Solidago (near Sta. I, a), Aug. 11 and 12 (Nos. 20 and 

 26) ; by T. L. Hankinson (Sta. I) July 3, 191 1 (No. 7665) ; on flow- 

 ers of Pycnanthenmm (Sta. II) Aug. 13 (No. 52) ; and from the 

 flowers of Bryngium yuccifoliiim (Sta. II) Aug. 13 (No. 55) ; and 

 from the cleared area bordering Bates woods (Sta. IV, a) Aug. 2^ 

 (No. 146). 



Packard (Guide to the Study of Insects, 8th ed. p. 177. 1883) 

 states that this wasp flies "low over hot sandy places." This is one 

 of the species found by Banks (Jour. N. Y. Ent. Soc, Vol. 10, p. 210, 

 1902) to sleep in grass, and by Brues (idem, Vol. 11, p. 229. 1903) 

 resting during the day and night upon plants. 



ScouiD^ 



Scolia bicincta Fabr. 



This hirsute black wasp, with two yellow transverse dorsal bands 

 on the abdomen, is represented in our series by four specimens. Three 

 of these were taken on flowers of Pycnanthenmm pilosum from the 

 clearing bordering the upland portion of the Bates woods (near Sta. 

 IV, a) Aug. 23 (No. 146) ; the others, from an open space in the up- 

 land forest (Sta. IV, «) Aug. 26 (No. 163). I have also taken this 

 species at Bloomington, III, Aug. 23, 1892, and Aug. 25, 1896. 



Packard (Guide to the Study of Insects, 8th ed., p. 176. 1883) 

 states that in Europe Scolia bicincta burrows sixteen inches in sand 

 banks, and that it probably stores its nest with grasshoppers. Riley 

 (First Rep. U. S. Ent. Comm., p. 319. 1878) states that species of 

 Scolia are known to have the habit of stinging grasshoppers and 

 digging nests, j)rovisioning these with grasshoppers, on which they 

 lay eggs as does the wasp Chlorion cyaneum Dahlb. (C. ccrrnleiiin 

 Drury). (Cf. with Kohl, Ann. des K. K. naturhist. Hofmuseums, Bd.
