WILLIAM G. DIETZ, M. I). 
As already pointed out by LeConte (op. cit. ]). 109), this cannot 
lie A. he/vohts Boh. (Sch. Gen. et Sp. Cure. vol. vii, 2, p. 224), as the 
description “ feinorihus anteriorihus hreviter unidentatis, posticis 
muticis,” and again, “Thorax latitudine postica nonnihil hrevior,” 
does in no wise correspond with the species under consideration. 
Subgemis Anthonomus. 
I have hut little to add to the definition of the genus as here re- 
stricted, to what has been given in the table. The fifth ventral seg- 
ment of the male is hut rarely emarginate. The funicle is 6-jointed 
in but a small number of species. 
The present suhgenus contains by far the greatest number of spe- 
cies, which j)resent structural differences of considerable importance, 
and which I have made use of in subdividing the species into the 
following groups : 
Funicle seven-jointed. 
Upper surface pube.seeut (scales, if auy, are arranged in spots or lines, except A. 
concinnus ) ; claws strongly toothed. 
Elytra conjointly rounded at the apex; pygidiuin of % very little exposed; 
pubescence dense, arranged in patterns on the elytra. 
nebulosus Group. 
Elytra not conjointly rounded at the apex ; pygidiuin, at least of the male, more 
fully exposed ; pubescence uniform, or condensed in spots or lines 
without distinct patterns. 
Anterior femora bidentate gularis Group. 
.interior femora unidentate. 
Third ventral segment longer than the fourth; fifth segment shorter, 
rarely as long as the fourth in the male. 
Pubescence of elytra uniform, rarely condensed in spots or lines, and 
without denuded patch or fascia. PI. vi, fig. I4...suturalis Group. 
Elytra with spots or lines of condensed pubescence, enclosing a denuded 
patch or fascia. PI. vi, fig. 15 sig-natus Group. 
Third and fourth ventral segments equal or nearly so; fifth segment of 
male longer than the fourth. PI. vi, fig. 16....scutellatus Group. 
Upper and lower surface pubescent; claws armed with a small, inconspicuous 
tooth juniperinus Group. 
Upper and lower surface clothed with scales; tarsi long squamosus Group. 
Funicle six-jointed. 
Claws armed with a large, distinct tooth subfasciatus Group. 
Claws armed with a short basal tooth ung-ularis Group. 
nebulosus Group. 
I have nothing fuither to add to the description of this group, 
as given in the synopsis, except that the tooth of the claws is rather
