LOCUSTARI^E. 



Thyreonotus dorsalis (Burm.) Scudd. 2 d", 1 ?, taken at Ft. 

 Reed, April 4-20. This species does not agree in structural character- 

 istics with any of the genera of Decticidae given by Herman, but 

 approaches Thyreonotus more closely than any other. 



Beloceplialus subapterus Scudd. (Acanthacara acuta Thorn, 

 nee Scudd.) A larval <3 was found at Ft. Reed, April 1 7. 



Xiphidium ensiferum Scudd. A single pupa of this or an 

 allied species was taken at Ft. Reed, April 21. 



Amblycorypha rotundifolia (Phylloptera rotundifolia Scudd.). 

 A single female came with the collection of Mr. Comstock, but un- 

 labelled. As some western specimens were sent, this may not have 

 been taken in Florida. I have received it from as far south as 

 Georgia. 



Microcentum retinervis (Burm.) Scudd. A male, a female 

 and two pupae were taken at Ft. Reed between April 4 and May 2. 



ACRYDII. 



Dictyophorus reticulatus Thunb. A considerable number of 

 larvae and pupae were taken May 6. They differ rather remarkably 

 from the perfect insect, being of a very deep metallic bronze-green 

 color approaching black, marked with yellow deepening into red in 

 spots, or wholly with blood-red ; this is most conspicuous in a slender 

 dorsal stripe the whole length of the creature, extending over the 

 fastigium half way down the lateral edges of the frontal costa; the 

 lateral carina? of the head, the lower border of the front and the lower 

 half of the posterior border of the head are also marked broadly 

 with it, as also the hinder edge of the pronotum; the antenna? are 

 black throughout. 



Aptenopedes ('a7m?'y, izrjddw) nov. gen. 

 Head projecting, front strongly oblique, whole summit of head hor- 

 izontal, scarcely convex, triangular; the eyes nearly meeting above, 

 and the fastigium in advance of them slightly tumid ; front sub- 

 appressed, particularly in the ? ; frontal costa distinct and equal 

 throughout; eyes long oval, not prominent, in the ? depressed and 

 tapering above; antennae moderately slender, linear, subdepressed, 

 about as long as (?) or slightly longer than (c?) the pronotum; palpi 

 rather small, the last joint nearly cylindrical, not in the least ex- 

 panded. Pronotum regularly expanding posteriorly in the ? , only
