50 T. D. A. and W. P. Cockerell on Bees. 
we have a male from the Khasia Hills, India, sent by 
Mr. Sladen. The face is yellow below the antenne ; scutel- 
lum prominent and bilobate; abdomen marked on apical 
segments with yellow. This has the mouth-parts nearly as 
in Megachile, but the ornaments of an Anthidium. It appears 
to be the most primitive of the Anthidine. 
ANTHIDIUM, Fabr. 
Here falls A. manitcatum and such American species as 
A. Portere and A. maculosum. 
Diantuiptiuy, Ck. 
This was described as a subgenus, but it should probably 
be regarded as a genus. Its type is D. curvatum (Anthidium 
curvatum, Smith), and D. parvum (Anthidium parvum, Cress.) 
1s quite congeneric. 
The little group of D. gilense (CkIl.), D. Hhrhorni (CkIl.), 
D. notatum (Latr.), D. perpleaum (Smith), and D. strigatum 
(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 Mianthidium. LD. gilense, in 
particular, falls with Anthid/um if 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 w :— ;

The nesting-habits of Dianthidium and Anthidium seem 
not to be the same; compare J). consimile (Hut. News, 1896, 
p. 25) with Anthidium manicatum and A. parosele. 
PARANTHIDIUM, subgen. nov. 
Type Dianthidium perpictum (Anthidium perpictum, Ckll.). 
This has the primitive character of 3-jointed maxillary palpi, 
but the venation of Dianthidium.

* We have this species from Marseilles, France, sent by M. Ernest 
André. It seems that, according to the law of priority, it ought to be 
called D, minus (Apis maculata, var. minor, Rossi, 1790),
