ward being broadly obtuse-angulate in both sexes. First two or three ab- 

 dominal segments strongly rugose-punctate. Supra-anal plate of male 

 triangular, with sides subparallel on basal half, sinuous and converging 

 toward the obtuse-angled apex; its surface with a median sulcus on basal 

 half and another on apical third; furcula very short, narrow, strongly di- 

 verging flattened lobes. Cerci much as in typical sphenarioides, their api- 

 cal halves more acute. Length of body, $, 16 21, 9, 25 33; of antennae,

 6 (W. 8. B.}. The males of this wingless Acridiau, with their 

 pink margined pronotal disk, bright blue hind tibiae and pink tarsi 

 are in life among the most handsome of Florida locusts. They 

 are much more scarce than the females and about Dunedin have 

 mostly been taken by beating the foliage of a tall scurfy Ericad, 

 Xolisnia ferruginea Walt., which grows in clumps in very dry, 

 sandy localities. The females occur on the same shrub, but more 

 frequently on a much lower one, Xolisnia fruticosa Michx,, and on 

 or among low huckleberries and other Ericads in open pine woods. 

 Not more than three males and a dozen mature females have been 

 taken in any one winter, though the nymphs are quite frequent 

 from February to April. The species was described from Fort 

 Reed, Fla., and has been recorded by other collectors from numer- 

 ous localities throughout that State, and from some of the south- 

 ern keys, but is usually everywhere much less common than splie- 

 iiiirioides. Davis (1014, 19G) says: ''This species is active at 

 night and it is no uncommon sight to see several of the grass- 

 hoppers devouring the leaves of the scrub palmetto, in which they 

 make half-moon shaped cuts; eating down to the midrib." 



The known range of A. (iptci-a is practically the same as that 

 of sphenarioides, extending, according to R. & H., "from Jesup and 

 Homerville, Ga., southward over peninsular Florida and on Big 

 Pine Key." As already noted, the males of A. rufovittata Scud- 

 der, are to be referred to this species. 



VIII. PARATYLOTROPIDIA Scudder, 53 1897, 117. (Gr., "beside" + 



"keel.") 



Rather stout, somewhat compressed species, having the head 

 large, protuberant, not broader than pronotum ; face moderately 

 oblique ; vertex broadly arched, not elevated ; fastigium very broad, 

 swollen, feebly declivent, its apex rounded ; eyes oval, one-half 

 longer than broad ; antenna? slender, as long as, female, or longer, 



53 Brunner (1893, 147) characterized and named this genus, basing it on the then unde- 

 scribed species P. brunnca Scudd. which he did not name. Scudder was therefore the 

 first to validate the genus by ascribing to it a fixed species.
