pale at base. Head not very large ; vertex between the eyes scarcely 

 so broad as the basal joint of antennas, shallowly and broadly sulcate 

 in advance of the eyes; frontal ridge moderately broad, shallowly 

 sulcate throughout, slightly and regularly expanding beneath, obsoles- 

 cent next the clypeus. Pronotum broadening slightly and regularly 

 throughout, the anterior lobe almost twice as long as the posterior, 

 its surface very faintly and very sparsely punctate, the median carina 

 sharp but slight and equal ; posterior lobe with the median carina not 

 sharp but rather inconspicuous, the surface of the lobe both above 

 and on sides delicately rugulose ; lateral carinas wholly obsolete. 

 Terminal segment of male strongly upcurved, tumid posteriorly; 

 cerci rather stout but laminate, tapering at the very base, beyond 

 nearly equal, moderately broad, directed inward and backward and 

 bent obliquely a little downward, slightly expanded, well rounded 

 and scarcely thickened at the tip. 



Length of body, 15.5 mm.; of antennas, 8 mm.; of tegmina, 3 

 mm.; of hind femora, 10 mm. 1 d", Jacksonville, May 6. 



Pezotettix puer nov. sp. Caloptenoid m form. Head livid 

 brown, heavily mottled with dusky brown in small spots, often deep- 

 ening, especially above, to blackish brown; antennas dull yellowish 

 brown, deepening to dark fuscous beyond the middle, the basal joint 

 longitudinal, streaked more or less noticeably with blackish. Prono- 

 tum brownish yellow, more or less infuscated above, the upper por- 

 tion of the deflected lobes, especially in the male and in front, 

 heavily marked with piceous, sometimes scarcely infuscated in the 

 female only. Tegmina shaped and colored as in the preceding species, 

 but paler in the female than in the male, widely separated. Legs 

 variable in color, but generally dull yellowish brown, the hind femora 

 generally twice banded above, besides the black apex, the hind tibias 

 dull yellow mottled with brown at base and extreme tip, the rest 

 purplish glaucous. Head and pronotum shaped and sculptured as in

 out and straight, but not sharp. Terminal segment of male a little 

 upturned, the anal cerci slender beyond the thickened base, scarcely 

 tapering, gently incurved, the tip bluntly pointed.
