SUBFAMILY II. OEDIPODIX.E. 295 



from Virginia and North Carolina having the hind tibiae suffused 

 with reddish or pinkish, thereby approaching the southern Florida 

 form. Davis (1914, 195) records a Fire Island, N. Y., specimen 

 with pink tibiae. Hart (1907, 201) has mentioned the finding of 

 specimens at Waukegan, 111., with well marked orange tibiae. 



126a. TRIMEROTROPIS MARITIMA ACTA Hebard, 1915b, 402. Southern Sea- 

 side Locust. 



More slender and somewhat smaller than typical maritima from which 

 it differs mainly by the characters given in key. General color more buffy; 

 anal fields of tegmina usually immaculate, rarely speckled with darker; 

 discoidal and marginal fields usually much suffused or speckled with 

 darker buff, these markings often concentrated to form two vague darker 

 bands; other markings as in key. Disk of pronotum slightly more com- 

 pressed and narrowed in front of the principal sulcus; hind margin less 

 produced, the angle being normally rectangular. Measurements and varia- 

 tions in size all falling within the extremes as given for maritima. 



Little River, Fla., March 1719 (W. 8. B.) ; Palm Beach, Fla., 

 May 27 June 13. (Dury). There is no doubt but that acta is 

 only a southern form of maritima, replacing the latter along the 

 South Atlantic coast and bearing to it the same relation, be it color 

 variety, race or what not, that 8. picta does to 8. niarniorata. Davis 

 has numerous specimens taken at Riverhead, N. J., and near Ft. 

 Monroe, Va., that are intermediate in coloration between maritima 

 and acta. Of nine Ft. Monroe specimens, five have the hind tibiae 

 in great part pink, while in the others they are pale orange yellow. 

 The secondary genital organs of male are the same in both forms. 



T. in. acta is recorded by Hebard as being "widely distributed 

 but few in numbers everywhere along the middle and upper ocean 

 beaches at Miami, Fla. Individuals were, without exception, en- 

 countered on loose sand, either along the landward border of the 

 middle beach, or less often immediately back of this in areas of 

 high seaside oats, Uniola /><uii<-iil<ita L. The flight much resem- 

 bles that of maritima and is more direct than that of citrhui." It 

 is also known from Capron and Palm Beach, on the east coast, 

 and from several islands in and about Charlotte Harbor on the 

 west coast of Florida. 



127. TRIMEROTROPIS CITRINA Scudder, 1876a, 265. Citrus-winged Locust. 

 Form of T. maritima, the female somewhat larger. General color ash- 

 gray or yellowish-brown, sprinkled more or less with fuscous. Face usu- 

 ally light gray. Tegmina yellowish-brown, the dark spots aggregated into 

 three dark cross-bars, often indistinct in female, usually plainly visible in 

 male. Wings pale lemon-yellow at base, the fuscous band broad, its width 

 from one-fourth to one-fifth the length of wing; submarginal ray short, ex- 

 tending less than half way to base. Inner face of hind femora yellow with
