103. A. pyrirurine Smitli.— Moderately rohiist, wider behind, jeneopiceous; 

 elytra reddish hrowu ; suture darker; pubescence whitish, moderately conspicu- 

 ous, condensed at the bases of the third elytra) intervals and in a post-scutellar 

 sutural spot, forming a more or less evident triangle. Beak thick, sliorter than 

 the head and protliorax, punctate and pubescent. Antennse rather slender, first 

 joint subequal to the next two, second about reaching the eye. Front narrower 

 than the tip of the beak, with the two lines of punctures, which tend to coalesce ■ 

 eyes not prominent. Prothorax as long as wide, subcylindrical, a little wider 

 behind, moderately punctate, with a linear basal fovea. Elytra widening to 

 behind the middle; humeri not prominent; striae coarse; intervals rather 

 strongly convex, wider than the striae. Beneath moderately punctured ; claws 

 with a rather small tooth. Length 1.6-2 mm. ; .065-.08 inch. (PI. V, fig' 17). 



Hab. — Arizona. 



The females differ only by the slightly more slender, less pubes- 

 cent beak. The peculiar coloration will at once separate pyriforvie 

 from anything else in our fauna. It seems thus ftir not to have been 

 brouglit in by many of our collectors, all the specimens seen coming 

 apparently fi-om one source. 



104. .4. lividiiiii Smith.— Ferruginous; legs yellowish ; pubescence fine 

 sparse, yellowish. Beak ( ^ ) a little shorter than the head and prothorax, feel)ly 

 dilated at base and slightly narrowing toward the tip; ( ?; as long as the head 

 and prothorax, more slender, sparsely punctulate in both sexes, but smoother in 

 the female. Antennse inserted near the base, first joint but little longer than the 

 second and nearly reaching the eye. Front narrower than the tip of the beak, 

 with two lines of more or less confluent punctures; eyes rather prominent, more 

 coarsely granulate than usual. Prothorax a little wider than long; sides just 

 visibly converging to a little before the middle, then more suddenly narrowed 

 and strongly constricted before the apex; surface moderately closely punctate ; 

 basal fovea small, punctiform. Elytra one-half longer than wide: humeri moder- 

 ate; sides subparallel; intervals not much wider than the strife, more or less 

 convex. Beneath moderately punctate ; legs slender. Length I 6-1 8 mm • 

 .06-.07 inch. ■ - 



Rab.— Florida. 



Taken in some numbers, especially at Crescent City, by Messrs. 

 Hubbard or Schwarz. In his description Smith compares this spe- 

 cies with turbuleiitaiii on a basis of similarity in form. This is only 

 true in a very superficial sense, as structurally there is little affinity 

 between them. Though not very close, lividum must, by any 

 scheme, be placed in the vicinity of emaciipes and cannatam ; its 

 separation from these species here being merely for convenience in 

 tabular arrangement. Its cf)lor will always "be sufficient for its 

 instant recognition.
