species, but we have no evidence of this as yet. We suggest this 

 since a very similar condition in H. gillettei is clearly only of 

 geographic racial value in that case, as treated below. 



Specimens Examined: 6; 2 males and 4 females. 



Florida : Ocala and De Leon Springs. 



A male bearing the same data as the type and a female taken 

 the following day by Hebard are designated paratypes. The 

 series was taken between September 8 and 20, 1917 by Rehn 

 and Hebard. The species was exceedingly scarce, very long 

 search on four days having been made to secure the six examples. 

 It was evident that the date was very late for this species, as three 

 of the specimens when taken had each lost one of the caudal 

 limbs. 



Like gemmicula the species was found peculiar to very sandy 

 areas. At De Leon Springs one individual was beaten from a 

 dwarf oak in a wide sand scrub area, the other from dwarf oaks, 

 bay cedar and other bushes more than a mile distant in the sand 

 scrub. At Ocala the four specimens were secured in sandy flat- 

 woods by beating the undergrowth, which was composed of a 

 leguminous plant and bunch grass. 



Hesperotettix nevadensis termius 21 new geographic race (Plate VIII, 

 fig. 17.) 



This geographic race is based on a condition showing greatly 

 reduced tegmina and wings, developed over an apparently 

 restricted area of the species' distribution. Comparable with 

 this is Melanoplus occidentalis brevipennis Bruner. 22 In both these 

 species such a condition is constant over a certain area, elsewhere 

 in their distribution never being found 23 ; in the present species 

 intermediates from the regions of intergradation with nevadensis 

 gillehei are at hand. 24 It is possible that H. osceola, may prove to 



21 From Tepfjiios =last; as showing the highest specialization in this species. 



22 Described as flabellifer brevipennis. We find Melanoplus flabellifer Scudder 

 to be an absolute synonym of Melanoplus occidentalis (Thomas). 



23 We would note that in the normally short-winged Melanoplus scudderi 

 (Uhler) a long-winged condition is found, .though very rarely. In that species 

 the structure of the tegmina shows that such a condition is wholly attributable 

 to individual reversion to the primitive type, and should in no way receive 

 nominal recognition. 



24 Without the large series at hand it would be impossible to determine the 

 correct value of the features shown by the present material.
