AMERICAN COLEOPTKRA. 239 



Metasternuni sparsely nearly uniformly punctured from side to side. Eighth 

 anteunal joint triangular and nearly one-half longer than wide. Front tibiae 

 unisulcate, the posterior groove lacking or extremely indistinctly indicated, the 

 anterior groove fine and close to the margin. Middle tibiae not grooved. Length 

 1.8-2.5 mm. 



Hab. — Arizona, Tucson and Hot Springs, June ; Catalina Springs, 

 July (Hubbard and Schwarz collection); "Arizona" (Morrison); 

 Pinal Mountains (Wickhain) ; Nevada (Reno, Wickham) ; Califor 

 nia (Palm Springs). One specimen collected at Winslow, Arizona, 

 by Wickham is also referred here, though not true to type. 



16. C ca rin a I n in n. sp. — Brown, form elongate, parallel, a little less than 

 half as wide as long, not in the least gibbous in profile, pubescence very fine and 

 thin. Coarser punctures evident on the head, distinct at the sides of pronotum, 

 rather numerous but not very conspicuous on the elytra. Metasternuni strongly 

 carinate, punctures sparse throughout, but finer and more remote laterally. 

 Eighth antennal joint quadrate-triangular, very little longer than wide. Front 

 tibiae rather strongly dilated apically, the anterior sulcus lacking; middle tibiae 

 feebly grooved close to the hind margin. Length 2 mm. 



Hab. — Crescent City, Florida. Hubbard and Schwarz collection. 



Described from a single specimen, probably a male, as the eyes 

 are unusually large, being separated by only about two and one-half 

 times their horizontal diameter as seen from the front. Quite simi- 

 lar in appearance to ventrale, but the latter is a little less elongate, 

 with slightly longer pubescence and non-carinate metasternuni. 



17. C Ventrale Lee. — Color varying from red brown to piceous brown, 

 ventral surface paler. Form parallel, twice as long as wide, not at all gibbous in 

 profile, pubescence fine, rather sparse. Coarser punctures inconspicuous or 

 nearly absent on the head and thorax, very fine and sparse on the elytra. Meta- 

 sternuni sparsely punctate from side to side, the punctures a little larger and less 

 remote at middle. Eighth antennal joint quadrate-triangular. Front tibiae with 

 posterior groove. Middle tibiae finely grooved close to the posterior margin. 

 Length 2-2.4 mm. 



Hab. — Columbus, Texas, May ; New Iberia, Louisiana, June. 

 (Collection Hubbard and Schwarz). LeConte's type was from 

 Illinois. 



18. C pu no tat II in Lee. — Brown, cylindrical, twice as long as wide, not at 

 all gibbous in profile. Pubescence moderate; coarser punctuation always dis- 

 tinct, but variable. Metasternum strongly carinate, punctate throughout. 

 Eighth antennal joint quadrate-triangular, scarcely longer than wide. Front 

 tibiae deeply bisulcate, middle tibiae plainly sulcate. Length 2.1-2.8 mm. 



LeConte's type is from Louisiana; he also mentions a second 

 specimen from Georgia The material at hand includes specimens
