tapering ; median carina slight, fading in front of the legs ; 

 lateral carinae equally slight, minutely denticulate; surface smooth, 

 very sparsely and briefly pubescent, brownish testaceous, obscurely 

 dotted with black. Tegmina minutely pubescent, slender, reaching 

 the tip of the third abdominal segment, rounded at tip, very light uni- 

 form translucent brown, very faintly iridescent ; wings extending be- 

 yond the tegmina by more than half the length of a segment of the 

 abdomen, colored like the tegmina. Front legs long, pubescent; coxae 

 and femora of equal length, lighter than the prothorax, marked 

 irregularly, or dotted with blackish fuscous, furnished with long 

 spines on apical third; tibiae extremely short, enlarging apically 

 with four apical black tipped spines, of which one is much longer 

 than the others ; tarsi reaching just beyond the middle of the femora. 

 Abdomen very long and slender, of the color of the pronotum, and 

 more abundantly pubescent, with longer white hairs ; supraanal plate 

 long and tapering, triangularly lanceolate, carinate, projecting far 

 beyond the abdomen ; cerci long, equal, depressed, pubescent, 7- 

 jointed ; styles slender, tapering, nearly half as long as the supra- 

 anal plate. 



Length of body, 47 mm.; of antennae, 23 mm.; of prothorax, 

 -12.75 mm.; greatest width of same, 1 mm. ; length of tegmina, 18 mm. ; 

 of fore femora, 8 mm.; of fore tibiae, 1 mm.; of hind tibiae, 10.5 mm. ; 

 of cerci, 4 mm. 



1 d, Ft. Reed, April 24. The species has also been taken in Flor- 

 ida, by Mr. Norton, and I have others from Georgia, all of them 

 males. It differs conspicuously from 0. Scudderl Sauss., supposed to 

 come from Georgia, in the length of the prothorax. The specimens 

 in my collection agree perfectly with those labelled Thespis graminis 

 Bates' Mss., in the British Museum; as Mr. Bates is understood to 

 have abandoned his purpose of preparing a monograph of the Man- 

 tidae, based on the British Museum collection, I have no hesitation 

 in describing it, and adopting therefor the appropriate specific name 

 he has applied. 



A male pupa of another Mantid was taken at Ft. Eeed, April 7, 

 apparently belonging either to Miopteryx or to Thespis ; but cer- 

 tainly not to T. cubensis Sauss., the only species of either genus re- 

 corded from the neighborhood of the Southern States.
