EEHN AND HEBAED 143 



Description of i^emaZe.— Gainesville, Alachua County, Florida, August 

 16, 1905, (Rehn&Hebard), [Hebard Collection]. Size large; form elongate 

 and compressed. Head with the greatest width immediately ventrad of 

 the eyes contained one and one-half times in the greatest depth; occiput 

 considerably and regularly declivent; fastigium acute trigonal, low, elon- 

 gate fossulato-sulcate mesad, apex subdepressed, well separated from the 

 low, broad, slightly acutQ frontal fastigium; eyes prominent, slightly com- 

 pressed, very elongate elliptical, the greatest width contained twice in the 

 depth, the latter slightly greater than that of the infra-ocular portion of the 

 genae; antennae several times as long as the body." Pronotum moderately 

 sellate, nearly straight dorsad when seen from the side, but slightly elevated 

 cephalad and caudad, as a whole considerably compressed, the disk narrow, 

 moderately compressed mesad with the greatest caudal width of same con- 

 tained twice in the length; cephalic margin of disk sinuato-truncate, caudal 

 margin of disk moderately produced, very slightly acute-angulate; lateral 

 portions of disk with traces of angles cephalad and indications of shoulders 

 caudad ; surface of disk slightly caudad of middle with a broad V shaped im- 

 pressed figure; lateral lobes with the greatest depth contained one and one- 

 half times in the greatest dorsal length, cephalic margin sinuato-truncate, 

 ventro-cephalic angle rotundato-rectangulate, ventral margin sinuato- 

 truncate, ventro-caudal angle roundly obtuse-angulate, caudal margin 

 obliquely truncate, humetal sinus very broad, shallow, arcuate, the surface 

 of the lobes appreciably impressed immediately cephalad of the same. 

 Tegmina a third again as long as the body (exclusive of ovipositor), the 

 width at distal fourth contained about eight times in the length of the 

 same, the width at the proximal third being slightly but appreciably less 

 than at distal fourth; marginal field considerably expanded on proximal 

 fourth of tegmen, subarcuate, more sharply rounded distad than proxi- 

 mad; distal extremity narrowly rounded; discoidal vein with five to six 

 rami, the proximal of which is in the usual position of the median vein 

 and with which it appears to be analogous. Wings projecting distad of 

 the tegmina a distance equal to about a third the length of the latter, sub- 

 acute, the costal margin broadly arcuate distad. Abdomen subcomprcssed 

 proximad; disto-dorsal segment truncate distad, slightly arcuato-cmargi- 

 nate at the base of the cerci; supra-anal plate semi-elliptical in form, with 

 a medio-longitudinal sulcus which is' also indicated on the distal por- 

 tion of the adjacent segment; cerci terete, acute; ovipositor subequal in 

 length to that of the dorsum of the abdomen, deep, the greatest depth nearly 

 two-thirds the greatest length, decidedly bent-arcuate proximad, margin of 

 the dorsal valves serrulate on distal half, margin of ventral valves finely 

 crenulate for almost its whole length, becoming scrrato-dentate distad, sur- 

 face of the dorsal valves distad with approximately seven rows of low tooth- 

 like ridges, the ventral row with more numerous teeth than the others, sur- 

 face of the ventral valves with a number of similar tooth-like ridges placed 

 transversely on the distal section, these regularly spaced only along the 



" Not complete in the present specimen.
