. DESCRIPTIONS OF NEW CURCULIONID BEETLES OF 
THE TRIBE ANTHONOMINI. 
By W. Dwicur Pierce, 
Bureau of Entomology, Department of Agriculture, Washington, D. C. 
In the search for available parasites to use in the fight against the 
boll weevil (Anthonomus grandis), numerous new species have been 
found and records of hitherto unknown breeding habits made. A few 
interesting species contained in the U. S. National Museum are here 
described, either because they were collected in Texas or because of 
records accompanying them. This paper is published by consent of 
the officials of the Bureau of Entomology. The immature stages of 
the bred species will be described later. 
MACRORHOPTUS SPHAERALCIAE, new species. 
Numerous specimens were bred from the fruit capsules of Sphoe- 
ralcia angustifolia from material collected May 4, 1907, at Devils 
River, Texas, by F. C. Bishopp. 
Length 1.25 to 1.75 mm. Oblong, black, with elytra, legs, antennae 
and tip of beak, ferruginous. Densely clothed with elongate pale 
scales, which are somewhat concave, and are mixed with inclining 
clavate bristles. Vestiture of prothorax densest at posterior angles. 
This species is readily separated from either of the described species 
by its hight color (when unrubbed), its small size, and the inclining 
bristles. 
Type.—Cat. No. 10051, U.S.N.M. 
SMICRAULAX, new genus. 
Claws toothed; middle coxae separated by mesosternum ; posterior 
tibiae mucronate; scrobes short, almost reaching eyes, directed beneath 
eves; elytra quadri-tuberculate at base. The genus belongs near 
Cionistes, 
Name derived from optxpos, signifying short, and avlaé, signifying 
furrow, referring to the short scrobe. 
Type of genus.—Smicraulaa tuberculatus.
