Dec, 1917-] Davis: Sonoran Cicadas. 211 



Carrabelle, August 9, 1903, in the collection of Prof. Albert P. Morse. 

 In the author's collection are the following: Baldwin Co., Alabama, 

 July 8, 191 7, male collected "in a cypress on the beach by the bay" 

 (H. P. Loding) ; Ship Island, Miss., August 24, 191 5, female (Rehn 

 and Hebard) ; Mandeville, La., June, 1916, female (H. Edw. Hubert) ; 

 Timbalier Island, Terre Bonne Co., La., August 12, 1917, two males 

 captured among the black mangroves, Avicennia nitida (E. C. Wurz- 

 low). In Texas Mr. Knight collected at Richmond, June 23, 1917, 

 five males, and at Wharton, June 24, 1917, four males. These places 

 are about fifty miles from the coast. 



The twenty-five specimens in the author's collection of Uhler's 

 reperta, or viridifascia Walker, as we think it should be called, from 

 the Atlantic coast, differ in markings from those from the Gulf coast, 

 and still more so from those from Texas. The Atlantic coast speci- 

 mens are darker with the venation largely orange in color, the disk 

 of the pronotum is black with the elevated portions fulvous as de- 

 scribed by Uhler, and the collar, or hind margin of the pronotum, 

 is yellowish, or greenish, in some individuals. The w-mark has the 

 lower extremities of the w quite rounded. The tergum is dark, in 

 most of the twenty-five specimens of a chocolate color. There is the 

 dark area in the basal cell, as described by Uhler. 



The specimens from the Gulf coast so far examined are much 

 lighter in color, the disk of the pronotum is not as conspicuously 

 blackened especially along the front margin of the collar; the w-mark 

 has the lower extremities of the w more pointed, and the tergum is 

 more tawny. The nine specimens from Texas are marked like those 

 from along the Gulf coast, the basal cell in the fore wing, however, 

 is clear, slightly touched with black along the fore margin, and the 

 eyes are more prominent than in specimens from the Atlantic coast. 

 The genitalia appear to be alike in all of the specimens. Some of the 

 features mentiojied may be seen by a comparison of the figures given 

 on the accompanying plate. We consider that the Gulf coast and 

 especially the Texas examples, constitute a variety for which we 

 propose the name bequaerti. As the type of this variety a male from 

 Richmond, Texas, June 23, 191 7, has been selected, and is shown on 

 the plate at fig. 6. The male viridifascia figured, came from Beau- 

 fort, North Carolina.
