Goleopterological Notices, VI. 687 



The genus Anthicns, as here limited, may be said to comprise 

 those species of the tribe Anthicini which ha^e the mesosternum 

 normal and undilated, the last joint of the antennae entire, the 

 pronotum unmodified in structure, and the vestiture simple, — that 

 is, consisting of a single set of hairs, disregarding in this connec- 

 tion the erect setse which are especially tactile in function. The 

 last joint of the maxillar}' palpi is moderate in size and securi- 

 form, and the antennie are comparatively short and gradually 

 enlarged toward apex, — never capitate as in Sapintus. It is very 

 abundant in species throughout the United States, but, in com- 

 mon with all other heteromeride groups, is particularly well rep- 

 resented in the southwestern parts of the country and in the 

 regions bordering the Pacific Ocean. 



The species known to me may be identified by the following 

 provisional table : — 



Elytra with distinct humeri 2 



Elytra oval and convex, without humeri 27 



2 — Body hispid throughout with very long erect setoe 3 



Body with shorter pubescence 4 



3 — Head strongly rounded behind in circular arc 1 . Iiorridus 



Head truncate at base 2. rtlf tllus 



4 — Head strongly and semi-circularly rounded behind the eyes. 



Pale testaceous, the elytra biguttiilate :}. cribratus 



Bla<?k, the elytra quadriguttulate 4. becate 



Head truncate or broadly arcuate at base, the temporal angles more or less di.s- 

 tinct ; pronotum normally convex throughout, not modified near the 



apex 5 



5 — Larger or medium species, seldom under 2} mm. in length, the sides of the 

 prothorax generally oblique and arcuate toward base or the subbasal con- 

 striction, and broadly rounded anteriorly 6 



Small species never exceeding 21 mm. in length, the sides of the prothorax 

 generally more or less prominently rounded anteriorly, and oblique and 



nearly straight or feebly sinuate thence to the base 19 



6 — Abdomen rather coarsely and more spar.sely punctate; body jiale in color...? 



Abdomen always minutelj' and more or less densely punctate 10 



T — Pronotum simply punctate; apex of the copulatory sheath rapidly nar- 

 rowed, the extreme tip minutely prominent S 



Pronotum sculptured in longitudinal ruga;, the copulatory sheath gradually 



and arcuately narrowed to an ogival point, at least iu compositu>< 9 



8 — Temporal angles broadly rounded. 



Pubescence relatively long, coarse and conspicuous; elytral fiiscia generally 

 distinctly black. 



Eyes large, much longer than the tempora 5. eplii|>i>iuiii 



Eyes smaller, subequal in lejigth to the tempora 6. siniiolii^i
