I'JOT.] NATURAL .SCIKNCES OF rmLADIOLPHIA. 293 



The "ruhu/inofia" individuals from Pablo Beach are identical with 

 individuals from the coast of southern New Jersey, i.e., Cape May and 

 Anglesea. The form found in the interior of the New Jersey pine 

 rei>;ion possesses short tegmina and wings and, as a rule, is of smaller 

 size. If the recognition of alutacea and rubiginosa as distinct species is 

 conceded, it would also be necessary to sej^arate the pine land type 

 from the coast dune type. 

 Schistoceroa obscura (Fabricius). 



This form, which is separated from alutacea by the narrower incision 

 of the subgenital plate of the male and the color of the caudal limbs, 

 is represented by three males and five females. Of these six were 

 taken at Pablo Beach, August 11 and 12, in tall marsh grass and open 

 palmetto scrub; one female at Gainesville, August 16, in undergrowth 

 in pine woods, and another at Denmark, Bamberg County, S. C, 

 August 10, in high w^eeds. The males here referred to this species have 

 the subgenital plate with the lateral portions lapped over the incision, 

 while the caudal tibia) are decidedly blackish in all except in one female 

 which has them blackish purple. The bars on the dorsal face of the 

 caudal femora are indicated more or less distinctly in all the individuals, 

 but in no case are they prominent. The general base color of all the 

 females, and to a lesser extent of the males, is maroon, while the size 

 appears to be greater in the female than in the average of alutacea. 

 The coloration of the female of this species is very striking, but the males 

 do not present so rich an appearance. The real value of this form as 

 distinct from S. alutacea cannot l^e fully determined without the study 

 of a large amount of material, as the single character of the narrower 

 incision of the male subgenital plate alone can be relied upon, the greater 

 length of the antennae, size and coloration being variable in the allied 

 species. 



Two female specimens of this species from Maryland have also been 

 examined, one from Chestertown (August 17, 1898; E. G. Vanatta), 

 the other from Druid Hill Park, Baltimore (September, 1902; H. A. 

 Wenzel). These specimens extend the range of the species consider- 

 ably to the north of the former northern limit— North Carolina. 

 Gymnoscirtetes pusillus Scudder. 



This peculiar species is represented in the collection l)y a most inter- 

 esting series of 153 specimens taken as follows : Pablo Beach, August 

 11, 12 and 13, sixty-eight males, fifty-nine females, two nymphs; San 

 Pablo, August 13, seven males, four females; Gainesville, August 17, 

 foiu- males and seven females; Cedar Keys, August 15, one female. 



As a whole the series shows a considerable amount of variation in
