A. tnberciilatiis u. sp. — Rhoniboidal, robust, black, anteniife and legs pi- 

 ceous, upper surface very sparsely and finely pubescent, pubescence intermixed 

 with large pale scales, underside clothed with dirt-colored scales. Beak stout, not 

 quite as long as the prothoi^ax. slightly widened towards the apex, distinctly 

 cariuate, finely striate each side, punctured ; antennje slender, funicle 6-jointed, 

 first joint stout, elongate, joints 2-3 shorter and more slender, three outer joints 

 widened towards the clava, latter elliiitic, acuminate ; eyes only partially con- 

 cealed in repose. Head convex, finely and sub-confluently punctured ; prothorax 

 one-half wider than long, rounded on the sides, broadly constricted at the apex, 

 anterior margin entire, subangulate each side, lateral tubercles distinct, acute, 

 dorsal channel evident from base to apical constriction ; disc closely and not very 

 coarsely punctured ; scutel not visible. Elytra little more than one-fourth wider 

 at the base than the prothorax, scarcely rounded on the sides and very distinctly 

 narrowed posteriorly, striae feebly impressed, punctures not distinct, interspaces 

 a little convex, about equal in width, each with a row of large conical tubercles 

 interrupted by a transverse belt before the declivity, tubercles without setae, 

 spaces between the tubercles rugulose; pygidium and under surfrce not coarsely 

 punctured. Legs long, tibiae very slender, middle and posterior not emarginate 

 above the apex, tarsi slender, third joint not very broadly bilobed, fourth shorter 

 than the two preceding joints combined, claws armed with a long slender tooth. 

 Length 2.5 mm. ; 0.10 inch. 



Hab. — Arizona. 



A female s]>ecimen in Dr. Horn'.s coll. The occurrence of a spe- 

 cies with 6-jointed antenna! funicle in the subtribe Conliodes is rather 

 auonialous. Its nearest ally is asper, which it resembles in its promi- 

 nent and conspicuous elytral tubercles, and from which it ditiers aside 

 from the 6-joiuted funicle by its broader form, equal elytral inter- 

 spaces, the tubercles not setiferous, and the simple middle and poste- 

 rior tibiffi. 



A. siibraseiatiis n. sp. PI. xii, fig. 12.— Broadly oval, pitchy black, legs 

 piceous, tarsi paler; very thinly clothed with a very fine and short pubescence- 

 elytra with j)atterns of large white scales. Beak elongate, stout, about as long as 

 the prothorax, slightly widened towards the apex, coarsely sculptured, substriate, 

 stria; irregular, with intervening elevated lines, glabrous in its ai)ical third. Eyes 

 concealed in repose. Head convex, coarsely punctured ; prothorax more than 

 one-half wider than long, about one-fourth wider at the base than at the ai)ex. 

 rounded on the sides, broadly and not strongly constricted at the apex, postoc^ular 

 lobes strongly developed, apical margin with two minute, rather distinct cusps, 

 lateral tubercles distinct, dorsal channel ill-defined ; surface very coarsely punc- 

 tured; scutel not evident. Elytra one-third wider at the base than the pi'otho- 

 rax, not longer than wide, humeri very prominent, rounded on the sides from 

 the humeral prominence to the apex, striae deep, not wide, punctures rather 

 small, interspaces convex, each with a row of very small, acute granules, each 

 bearing a conspicuous, short hair, a cruciform spot of white scales, the transverse 

 bar about one-third from the base and narrowly separated from an interrupted, 

 lateral fascia a little before the middle ; pygidium with large, not close set punc- 

 tures, more strongly convex in the female ; pectoral canal extending upon the
