Curtomerus subflavus, new species 



Male: Form robust, somewhat depressed; color uniformly brownish 

 testaceous, appendages slightly paler; pubescence golden, moderately 

 dense. Head finely, shallowly, confluently punctate on vertex and 

 front, area between prominent antennal tubercles shallowly concave, 

 median line not deep; erect, stiff setae numerous around mouthparts, 

 pubescence sparse, short, subdepressed and suberect elsewhere; 

 antennae extending about two segments beyond elytra, segments 

 from second densely clothed with very short, appressed pubescence, 

 long erect hairs dense along inside margin, long hairs also numerous at 

 outside margin of basal segments, scape shining, finely densely punc- 

 tate, sparsely clothed with long, suberect and short, appressed hairs, 

 third segment slightly longer than scape, fourth subequal to scape, 

 fifth longer than third, eleventh longer than tenth. Pronotum about 

 as long as broad, sides rounded, base deeply constricted, impressed 

 at sides, apex feebly constricted, not impressed; disc flattened, with a 

 median, longitudinal, nonelevated, glabrous callus ; punctures around 

 median callus coarse, confluent, rugose appearing from basal margin 

 to apical one-thu'd of disc, punctures finer and separated toward 

 apex, sides at apex and base very sparsely punctate; each puncture 

 giving rise to a long, suberect, yellowish hair ; prosternum not impressed, 

 with distinctly delimited, densely punctate areas extending from sides 

 of pronotum to narrow, glabrous, central area which joins the trans- 

 versely impressed collar, pubescence sparse; meso- and metasternvim 

 sparsely punctate and pubescent; scutellum small, subglabrous. 

 Elytra less than 2K times as long as broad; basal punctures finer than 

 those of pronotal disc, separated, becoming fhier and sparser only 

 at extreme apex; pubescence consistmg of long suberect, recurved 

 bail's, each arising out of a puncture; each elytron strongly bicostate; 

 apices rounded. Legs with femora strongl}^ clavate, minutely 

 punctate, pubescence long, suberect and short, appressed. Abdomen 

 shining, very sparsely punctate and pubescent; apex of last sternite 

 rounded. Length 12 mm. 



Female: Antennae slightly shorter than body; prosternum shining, 

 very sparsely punctate, shallowly rugulose; apex of last abdominal 

 sternite subtruncate. Length 9-10 mm. 



Holotype male (USNM 67326), allotype female from Flat Top 

 Point, Anguilla, B.W.I. , Apr. 13, 1958 (J. F. G. Clarke); one female 

 paratype from Sopers Hole, Tortola, B.V.I., Apr. 5, 1958. 



The coarse, confluent punctures surrounding the median glabrous 

 callus of the pronotum wiU distinguish C. subflavus from the other 

 known Curtomerus.
