SMICRONYX WEEVILS—ANDERSON 343 
Briotoay: There is no information available on the biology of this 
species. 
Discussion: It is unfortunate that there are only three specimens 
of S. floridanus available for study, particularly in regard to the 
genitalia, but since the available material does not closely resemble any 
other species, the name is allowed to stand at this time. To some 
extent, this species resembles S. compar Dietz in regard to general 
body shape, color, and prothoracic punctation. However, the scales 
of the dorsum are a mixture of white and light tan in S. jfloridanus, as 
opposed to various shades of yellow in S. compar, and the rostrum of 
the male of S. floridanus is distinctly carinate before the antennal 
insertions, which is not true of S. compar. 
Distripution: From the type locality (Florida) and a single speci- 
men in the Dietz collection marked ‘‘Geo.,” it is evident that S. 
floridanus must exist at various points in Florida and Georgia, but 
more specific information is lacking.

MCZ 1916 (Dietz collection). 
Description: Rostra of both sexes reddish brown, slightly curved; 
roughly punctate and squamose behind antennal insertions, closely 
punctate before antennal insertions in male; less roughly punctate 
behind antennal insertions, very smooth and shining before antennal 
insertions in female. Head reddish brown, finely alutaceous and 
sparsely punctate. Antennae reddish brown, second funicular seg- 
ment subequal to first. Prothorax dark reddish brown, moderately 
rounded at sides, moderately narrowed and slightly constricted toward 
apex; disk closely and coarsely punctate, a trace of a smooth median 
line near apex; scales elongate-oval, pale luteus to white; prosternum 
shallowly emarginate, transversely impressed. 
Elytra reddish brown; intervals covered with scales similar to those 
of the prothorax. Underside of thorax and abdomen covered with 
broadly ovate, white scales. Femora reddish brown, moderately 
clavate, covered with elongate-ovate yellowish white scales. ‘Tibiae 
reddish brown, thinly covered with elongate yellowish white scales. 
Tarsi piceous to reddish brown; fourth segment extending well beyond
