as the abdomen; the lateral marginal stripe white; the abdomen a shin 

 ing dark-brown. 



JDimensions. — 9 , Length, 1.25 to 1.5 inches. Specimens were received 

 from Mus. Comp. Zool., Cambridge, and from the Agricultural Depart- 

 ment, Washington. 



Pyrgomorpha brevicornis, Walk. 



Male. — Sides of the head, prohotum, and of the closed elytra perpen- 

 dicular, flat, compressed. Top of the head slightly ascending to the tip of 

 the vertex; the vertex between the eyes rather broad, slightly convex ; the 

 portion in front of the eyes short, scarcely exceeding its width, rounded at 

 the apex ; a very slight median carina in the front portion ; margins 

 scarcely raised ; no foveolae. Face quite oblique, straight, narrow above 

 and expanding below, quadricarinate ; the carinse minute but distinct, 

 moderately divergent, reaching to the clypeus. Antennae longer than the 

 head and thorax, enlarged at the base, triquetrous. Byes placed high 

 and well forward, oblique, ovate, acuminate at the apex. Pronotum a 

 little longer than the head; sides parallel; tricarinate, the three carinse 

 distinct but not elevated, the lateral consisting of the angle formed. by 

 the perpendicular sides with the nearly flat disk; one minute transverse 

 incision a little behind the middle. Elytra and wings extend about one- 

 third their length beyond the extremity of the abdomen; the former 

 obliquely truncate at the tip. Posterior femora slender, nearly as long 

 as the elytra. Subanal plate conical. 



Color. — Brown and green. Face, and the entire dorsal surface, uni- 

 form bright green; the entire sides fuscous brown; anterior and middle 

 legs and posterior femora green; posterior tibiae dusky; spines white, 

 tipped with black; antennae brown. 



dimensions. — Length, 0.91 inch; length to tip of elytra, 1.25 inches; 

 elytra, 0.86 inch; posterior femora, 0,64 inch. 



Bemarlc. — This specimen, which is from Texas, received from Mus. 

 Comp. Zool., is evidently Pal. Beanvois' Truxalis notochlorus. I am 

 now very strongly inclined to the opinion that my F. punctipeniiis is but 

 a variety of this species. I am also well satisfied that this is the species 

 I saw at Murphysboro, Illinois, which produced such a loud crackling 

 noise in leaping. (Rept. Ills. St. Agl. Soc, vol. v.) 



Gompliocerus simplex, Scudd. 



I have a specimen of what I am inclined to think is Mr. Scudder's G. 

 simplex, which was collected by Mr. Uhler in Maryland, and communi- 

 cated to me by Prof. T. Glover ; but as it varies somewhat from Mr. 

 Scudder's description, I give here a full description : 



3Iale. — Back part of the head ascending, tricarinate; these three carinas 

 minute, but distinct and close together ; the lateral ones bend suddenly 

 outward at the upper angle of the eyes and connect with the raised 

 margins of the vertex; the median carina continues to the tip of the 

 vertex; vertex slightly ascending and rounded in front; no lateral 

 foveolae. Face quite oblique and slightly arcuate ; frontal costa rather 

 broad, of equal width throughout, and sulcate ; lateral carinae distinct, 

 divergent. Antenna about as long as the head and thorax ; the club very 

 distinct, commencing at the thirteenth or fourteenth joint. Pronotum 

 with the sides nearly parallel ; the lateral carinaB curving inward slightly 

 about the middle ; the three slight carinae of the head are continued 

 with equal distinctness along the middle of the pronotum, parallel, and 

 preserving the same distance from each other as on the head ; the lateral
