50 T. D. A. and W. P. Cockerell on Bees. 



we liave a male from the Khasia Hills, India, sent by 

 Mr. Sladen. The face is yellow below the antennae ; scutel- 

 lum prominent and bilobate ; abdomen marked on apical 

 segments with yellow. This has the mouth-parts nearly as 

 in Megac/iile, but tiie ornaments of an Anthidium. It appears 

 to be the most primitive of the Anthidiinae. 



Anthidium, Fabr. 



Here falls A. manicatum and such American species as 

 A. Porterce and A. maculosuni. 



DiANTHIDIUM, Ckll. 



This was described as a subgenus, but it should probably 

 be regarded as a genus. Its type is D. curvatum (Anthidium 

 curvatuni, Smith), and D.parvum { Ani/iidium porvuni, Ciess.) 

 is quite congeneric. 



The little group of B. gilense (Ckll.), D. EhrhorniiGkW.), 

 D. nolatnm (Latr.), D. pirjiJcxum (Smith), and D.strigatam 

 (Panz.) *, all described under Anthidium, is possibly of sub- 

 generic value, and in respect to its labial palpi falls more or 

 less between Anthidium and Dianthidium. D. gilense, in 

 particular, falls with Anthidium \i its mouth alone is regarded, 

 and so far presents an argument against the generic status 

 of Dianthidium. 



The following measurements of the first two joints of the 

 labial palpi are in /x : — 



D. strigatum ... (1) 650, (2) 870. 



D. gilense .... (1) 7:^0, (2) 760. 



D.parvum ... (1) 720, (2) 1220. 



D. inrpictum . . . (1) 6.50, (2) 1200. 



A . manicatum . . . (1)1300,(2)1320. 



A. Portenv ... (1) 1200, (2) 1000. 



The nesting-habits of Dianthidium and Anthidium seem 

 not to be the same; compare D. consimile (Enl. News, 1896, 

 p. 25) with Anthidium manicatum and A. paroselce. 



Paranthidium, subgen. nov. 



Type Dianthidium perpictu7n [Anthidium perpictum, Ckll.) . 

 This has the primitive character of 3-jointed maxillary palpi, 

 but the venation of Dianthidium. 



East Las Vegas, New Mexico, U.S.A., 

 October 20, I'JOO. 



♦ We have this species from Marseilles, France, sent by M. Ernest 

 Andr^. It seems that, according to the law of priority, it ought to be 

 called D. mintis (Ajns maculata, var. minor, Rossi, 1790).
