202 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



originally reported from similar environment near Emporia and 

 Enterprise Junction) . Like the latter species it is probably very 

 locally distributed and is supplanted in the surrounding more 

 extensive areas of different ecology by related races or species. 



It is superficially quite similar to altera simplex here de- 

 scribed, but the dorsal lobes of the penis are definitely more 

 chitinous, produced in a blunt decurved finger dorsad and a 

 smaller and much shorter finger ventrad, with intervening lat- 

 eral margin broadly concave. This is much like the type 

 developed in aptera coquinae here described except that in that 

 southeastern race the dorsal finger is much shorter and heavier. 

 The dorsal pair of parameres rather suggest those of aptera 

 aptera but are definitely narrower and more produced. 



It is probable that this race will be found only locally, in 

 central eastern Florida. Intergradation with aptera coquina 

 may appear in material from along the northern portion of the 

 Indian River. 



Type. — S ; DeLeon Springs, Florida. September 9, 1917. 

 {Rehn and Hebard). [Hebard Collection, Type No. 1294]. 



Generally similar in external structure to aptera simplex here described, 

 differing as noted above. Size and form similar, averaging smaller and 

 less robust than the other races. Penis with basal portion very large, dorsal 

 lobes dark, more strongly chitinous than in the preceding races (but agree- 

 ing with aptera coquinae) of distinctive form as described above; dorsal pair 

 of parameres rather suggesting those of aptera aptera but more produced, 

 very much less produced than in aptera coquinae, in dorsal aspect other- 

 wise similar to those of aptera aptera but not as much expanded. 32 



Allotype. — $ ; same data as type. [Hebard Collection]. 



Indistinguishable from females of aptera simplex. 



Coloration as described for aptera simplex. Lateral pronotal lines and 

 medio-longitudinal dorsal band of abdomen of males usually whitish, some- 

 times faintly tinged with pinkish. Females with the abdominal band only, 

 this narrower, not continued on the pronotum in either sex. 



Specimens Examined. — 16; 8 males and 8 females. 



Florida: DeLeon Springs, IX, 8 and 9, 1917, (Rehn and Hebard; not 

 scarce in dwarf oaks throughout extensive sandy scrub area) , 8 $ , 8 $ , type, 

 allotype, paratypes. 



32 Atypical material of aptera coquina more strongly indicates that aptera 

 saturiba is definitely more closely related to it than to aptera aptera.
