smaller than the Miami individual, but has the o\'ipositor longer. 

 Both are of a brownish color, which apparently is the natural coloration. 

 The tcgmina and wings are present as very small pads. 



Pyrgocorypha uncinata (Harris). 



This striking species is represented by four specimens, two from 

 Miami, one taken July 11, 1903 (immature), the other without date, 

 and two from Chokoloskee. They agree very well with Mexican 

 specimens. 



Conooeplialus mexicanus Saussure. 



Three specimens represent this species, one from Tampa, taken 

 January 15, 1904, the others from Miami, taken February 5, 1903, and 

 February 6, 1904. 



Tampa. — I took this specimen in a marshy spot on the shore of 

 Tampa Bay. 



Miami. — One specimen was captured in a bush about 9 P.M. It 

 was making a deafening noise. I saw and heard several other speci- 

 mens, but all these when approached flew swiftly aw^ay. 



Conocephalus lyristes n. sp. (PI. I, figs. 8 and 9). 



Type: 6^, Chokoloskee, Monroe county, Florida. [Hebard collec- 

 tion,] 



Apparently allied to Conocephalus truncatirostris Redtenbacher from 

 Brazil, C. exiliscanorus Davis from Staten Island, and C. bruneri 

 Blatchley from Indiana. From the former it can readily be distin- 

 guished by the slenderer head and smaller size, while the shape of the 

 fastigium will separate it from the latter species. 



Size medium; form rather slender and moderately compressed. 

 Head v/ith the occiput and vertex horizontal, the rostrum elongate 

 and produced into a rather slender, bluntly rounded process which is 

 distinctly longer than the interspace between the eyes, ventral surface 

 with a blunt basal tooth; frontal fastigium produced, but not quite 

 touching the process of the rostrum; eyes rounded ovate in outline, not 

 very prominent. Pronotum deplanate dorsad; lateral angles not dis- 

 tinct cephalad, distinct but rounded caudad; cephalic margin subtrun- 

 cate, caudal margin broadly arcuate; lateral lobes equally long and 

 broad, the ventral margin obtuse-angulatc, humeral sinus rather broad 

 and shallow. Tegmina long and narrow, very considerably surpassing 

 the caudal femora. Cerci thick, heavy and parallel, apically with a 

 strong, recurved, aculeate spine on the internal margin, dorsad of which 

 is placed another of similar character but smaller size; subgenital plate 

 with a broad apical V-shaped emargination and with short but distinct
