Recognition. Linogeraeus perscitus View in CoL is a 2.4–3.2 mm long, reddish brown species with a distinctive color pattern, i.e., with light yellow scales on the pronotal flank, at the base of interstriae 1 and 3, and variously scattered elsewhere ( Fig. 39 View Figs ). Remotely similar species occur only in South America.

Distribution. This species has been found from the United States southward to Uruguay and Argentina as well as in the Lesser Antilles.

Type locality. North America, site not specified.

Material examined. United States: Arizona ( USNM 1 About USNM ) , Connecticut ( CWOB 2 ) , District of Columbia ( USNM 2 About USNM ) , Florida ( USNM 1 About USNM ) , Georgia ( CWOB 1 ) , Iowa ( USNM 4 About USNM ) , Kansas ( USNM 13 About USNM ) , Maryland ( USNM 4 About USNM ) , Massachusetts ( USNM 1 About USNM ) , Minnesota ( CWOB 3 ) , Mississippi ( USNM 5 About USNM ) , Missouri ( USNM 1 About USNM ) , Nebraska ( UNSM 5 About UNSM , USNM 6 About USNM ) , New Jersey ( USNM 1 About USNM ) , New Mexico ( CWOB 1 ) , New York ( USNM 1 About USNM ) , Ohio ( USNM 2 About USNM ) , Oklahoma ( TAMU 1 , USNM 1 About USNM ) , Rhode Island (2 larvae, USNM) , South Dakota ( USNM 1 About USNM ) , Texas ( CMNC 2 , CWOB 2 , TAMU 10 , USNM 5 About USNM ) . Argentina ( CWOB 14 ) , Colombia ( USNM 14 About USNM ) , Costa Rica ( CWOB 1 , USNM 2 About USNM ) , Curaçao ( USNM 3 About USNM ) , El Salvador ( USNM 1 About USNM ) , Guatemala ( TAMU 1 ) , Mexico ( TAMU 1 , USNM 6 About USNM ) , Nicaragua ( USNM 1 About USNM ) , Peru ( USNM 9 About USNM ) , Trinidad and Tobago ( CWOB 1 ) , Uruguay ( CWOB 7 ) , Venezuela ( CWOB 1 ) . Total 138 specimens .

Temporal occurrence. May to August, October [2 dates].

Plant associations. Chenopodiaceae : feeding on sugar beet (Bruner 1891; UNSM, USNM). Malvaceae : ‘‘bred in cotton boll’’ [ Gossypium sp. ], Peru (Townsend, cited by Pierce 1915; USNM); ‘‘on Cotton,’’ Colombia (J. Diaz,

observation). Portulacaceae : reared from roots and stem of Portulaca sp. (Mallia and Tuthill, observation; USNM, larval collection).

Note. Linogeraeus perscitus is widely distributed in North and South America but rather uncommon. In the United States, most specimens were collected in the Great Plains. The isolated records from the east coast ( Fig. 79 View Figs ) may indicate that L. perscitus has been at least partially dispersed by commerce. Several specimens in the USNM collection were found in association with cotton and it is conceivable that the weevil expanded its range with this or other crops. Linogeraeus perscitus seems to have been relatively common in the southern United States between 1895 and 1910.
