the preceding joint, fourth much longer than the third ; claws connate one-third 

 their length. Length 2.5 — 2.75 mm.; 0.10 — O.ll inch. 



Hah. — Arizona. 



Two specimens, S and 9 » Mr. Ulke's and iny own collection. 

 My specimen was collected by Mr. Wickham. A rather unusual 

 form, resembling somewhat Anthonomus afftnis Lee. in form and color 

 of its scales ; the latter, in conjunction with the form of thorax, 

 short second joint of funicle and narrow tarsi, makes this species 

 easy of recognition. 



S. lutuleiitu!^ n. sp. — Oblong-oval, black, shining when denuded of scales, 

 densely clothed with closely adherent and somewhat matted together, dark, 

 dirty gray or brownish scales. Beak (male) somewhat slender, curved, cylin- 

 drical, subopaque, punctured and scaly nearly throughout, except near the apex ; 

 basal tufts prominent, incision rather deep. Antennte moderate, first joint of 

 futiicle robust, second and third equal, short, clava small, basal joint subglabrous. 

 Head punctured and scaly. Prothorax one-half wider than long, narrowed an- 

 teriorly, about one-fourth wider at the base than at the apex, rounded on the 

 sides, apex constricted, densely punctured, punctures entirely concealed by the 

 scales, latter intermixed with stout, erect, scale-like hairs. Scutel very small, 

 almost invisible. Elytra one-third and rather suddenly wider than the protho- 

 rax. a little more than one-half wider than long, humeri prominent, sides ap- 

 pi-oximately straight for one-half their length, then broadly rounded to the apex, 

 striae impressed, not concealed by the scales, punctures somewhat approximate, 

 interstices slightly convex, setae erect, paler than the scales, obvious. Prosternum 

 not short iu front of the coxte, postocular lobes not very prominent. Thighs 

 strongly clavate; tibiae not slender, widened toward the apex, anterior eniar- 

 ginate in their distal half within; tarsi not very slender, third joint feebly bi- 

 lobed ; claws free nearly to the base. Length 2.0 mm. ; 0.08 inch. 



Hah. — Texas. 



Two males, Mr. Ulke's and my own collection. The dirty, grayish 

 brown color of its mattet scales, small size and short second funicular 

 joint readily distinguish this species from any other of the present 

 subo-enus. From pumlhis, which it resembles somewhat in appear- 

 ance, it is distinguished by its more compact form and dark blackish 

 legs. 



Griseus Group. 



The few species comprising this group recall here the facies of 

 certain Desmoris. The beak is straight, or approximately so ; slender, 

 especially in the female, the second joint of the funicle longer than 

 the third. The tarsi long and slender, the third joint deej)ly and 

 broadly bilobed, and the fourth shorter than the two preceding joints 

 combined. 



They may be distinguished as follows :
