thorax. Male beak as long as head and prothorax combined, slightly 

 curved, moderately dUated laterally and ventrally at antennal inser- 

 tion, nearly cylindrical beyond middle, tip slightly expanded; punc- 

 tures sparse, very fine, with a lateral row of coarse punctures above 

 antennal insertion, apical half shining, pubescence inconspicuous. 

 Female beak slightly longer than head and prothorax, slightly curved, 

 nearly cylindrical throughout, expanded slightly ventrally in basal 

 fourth, apex expanded; in basal half with a lateral row of coarse punc- 

 tiu-es above antennal insertion, apical half dull, alutaceous, pubescence 

 inconspicuous. Antennae inserted at distance from eye one-half 

 greater than width of frons, of male inserted slightly distad of basal 

 third, of female slightly distad of basal fourth; first segment equal to 

 next two segments, second segment equal to next two, club 0.18 by 

 0.08 mm. Ej^es moderately prominent; frons narrow, wider than 

 dorsal tip of beak, with a wide shallow median impression and a row 

 of four or five coarse punctures lateral to this; underside of head 

 deeply excavated and strongly polished. Prothorax one-third wider 

 at base than long, middle slightly narrower than base, apex three- 

 fourths as wide as base; sides moderatel}^ expanded laterally at base, 

 nearly parallel to middle, slight!}'" rounded to slightly constricted 

 apex; in profile dorsal surface nearly flat; punctation shallow, 0.03 mm. 

 in diameter, interspaces narrower than diameter of punctures; basal 

 fovea rounded, shallow. Elytra at humeri one-third wider than 

 prothorax at base, three times as long as prothorax, length to width 

 as 9 : 7 ; intervals twice as wide as striae, nearly flat, alutaceous, with 

 one row of fine, distant punctures bearing very fine scales; striae not 

 deep, with a row of scales slightly more conspicuous than those on 

 intervals. Scutellum triangular, about 0.06 by 0.04 mm., smooth. 

 Front femora 2.75 times as long as wide. Claws with acute basal tooth. 



Special male characters : Tibiae 2 and 3 armed with minute, simple 

 mucrones. 



Types: I hereby designate as lectotj^De of this species the male 

 specimen in the Fall Collection labeled Key West, Fla. (MCZ 25100). 

 Cotypes with the same data are in the J. L. LeConte Collection 

 (MCZ 364) and in the U. S. National Museum (USNM 4235). 



Material examined: Lectotype and 20 specimens. 



Known distribution: 



United States: Florida: Biscayne; Key West (MCZ, USNM). 

 Mexico: Tamaulipas: Tampico, December 8, E. A. Schwarz (USNM). 



Remarks: Material in the U. S. National Museum was reared by 

 E. A. Schwarz from Piscidea erythrina. 



The specimen from Mexico undoubtedly belongs to this species. It 

 differs in that the beak is somewhat more distinctly punctured toward 

 the apex.
