De Geer (Ins., 3, p. 499, No. 16) gives the following, description : 



" Acrydium (ensicornu). Green ; head conic ; antennae compressed ; 

 wings hyaline. 



" Gryllus acrida {brevicornis). Head prominent, green ; antennae com- 

 pressed, long as the thorax, Linn., Syst., ed. 12, p. 692, No. 2. Received from 

 Pennsylvania by M. Acrelius. It is of medium size, about sixteen lines in 

 length ; the elytra a little longer than the abdomen. The head is elongate and 

 conical above. Hat in front, in an oblique plane, so that the mouth appears as 

 though hid under the prothorax. The eyes and the antennae are placed at 

 the highest point of the conic part of the head. Tlie antennae, which are as 

 long as the head and thorax, are flat and enlarged at the base, but acuminate 

 at the apex; the eyes large, oval. The dorsum of the pronotum forms a 

 continuous plane with the head; has three slightly elevated carinee. The 

 elytra are straight ; and the posterior femora are of the same length as the 

 abdomen.'' 



Pal. Beauvois, Ins. Orth., 80, PI. iii. Fig. 3 : 



''TruxaUs notochlorus. — Fuscous; head conical; antennae longer than the 

 thorax ; head, thorax, elytra, and the wings above green ; wings below pale 

 yellowish; posterior femora longer than the abdomen. Saint Domingo, in the 

 humid savannas. This species is remarkable for the color of the back, which 

 is entirely green." 



" TruxaUs viridulus (p. 81, PI. iii. Fig. 4). — Head conic ; elytra green 

 above ; sides spotted with fuscous ; head and thorax pale green ; wings yel- 

 lowish ; antennae shorter than the thorax ; posterior femora a little longer 

 than the abdomen. Same country as the former. It is possible that this 

 species is the female of the preceding."* 



P. punctipenuis, sp. nov. 



Female. — Vertex slightly ascending, nearly in the same plane as the dorsum 

 of the pronotum, rounded in front; margins slightly raised; no lateral foveolae ; 

 the advance in front of the eyes not quite equal to the length of the eye ; a very 

 slight median carina. Face quite oblique ; seen from the side, curves slightly 

 inward Ix-lnw the vertex; regularly widening from Ihe apex of the eyes 



' The tiguies appear to couflrm this opiniou.
