selfe white, long, conspicuous. Prosteinuni rather short in front of tlie eoxse, 

 transversely impressed, prothoracic lobes moderately prominent. Legs and tarsi 

 as in the preceding. Length 2.2.") mm.; 0.10 inch. 



Hab. — Montana, Texas. 



Two specimens, % un<l 9 , in Dr. Horn's collection. Very closely 

 related to the preceding, from which it differs by its nearly uniform 

 ashey gray scales, the greater length of the second joint of the fu- 

 nicle, the less broadly oval elytra, and the shorter and transversely 

 inipresse<l prosternum ; the elytral setxe are also longer and more 

 conspicuous. 



S. iiiii>re!<$!>iiro»it.ris n. sp. — Subovate, modei-ately convex, black, antenna; 

 and legs rufopiceous, densely clothed on the underside with large, white or yel- 

 lowish white scales, scales on the upper surface smaller, brownisii, with irregu- 

 larly scattered {>aler sciiles intermixed. Beak longer, than head and prothorax. 

 feebly curved ; very robust in the male, slender in the female: indistinctly striate 

 and very feebly subcarinate, punctured throughout and scaly from base to l)eyond 

 the middle, in the male; less densely punctured, somewhat shining and sparsely 

 scaly in the female; basal tufts feeble, constriction marked, before the latter there 

 is a broad, distinct impression in the male; scrobes oblique. Head finely rugu- 

 lose, front punctate, scaly. Prothorax scarcely wider than long, narrowed in front, 

 not constricted at the apex, widest at the middle, sides rounded, feebly convergent 

 and nearly straight behind the middle; surface not very densely and rather 

 finely punctured, not closely scaly, an interrupted and not very evident vitta 

 each side of disc white; scutel distinct, glabrous. Elytra oval, less than one- 

 third wider at the base than the prothorax, sides regularly rounded, somewhat 

 compressed before the apex, striae rather fine, distinctly and remotely punctured, 

 interstitial setse moderately long, distinct; indistinctly mottled with pale, gray- 

 ish brown scales. Prosternum rather long in front of coxse, broadly sulcate. 

 Legs as in the preceding two species, tarsi not very stout, fourth joint projecting 

 nearly the length of the third ; claws connate one-half their length. Length 

 2.5 mm. ; 0.10 inch. Plate vii, fig. 10. 



Hub. — S. Illinois. 



A male and female specimen in my collection. Differs from the 

 preceding species by the thorax scarcely wider than long, and the 

 broad transverse impression at the base of the beak, which is more 

 feeble in the female; it diflers further from tesselatvs by the elongate 

 second funicular joint and the nearly unicolorous vestituie. 



profusus Group. 



This group contains some of the largest, as well as smallest, S})ecies 

 of the genus under consideration. They are generally elongate in 

 form with hun)eri prominent and the sides of the elytra parallel, 

 straight or nearly so. The beak in nearly all of them is rather 

 stout, especially in the males, the second joint of the funicle never
