Collected in Southern California by Mr. Crotch, and obtained by me 

 from the Museum of Comp. Zool., Cambridge, Mass. 



This very interesting species is the first, so far as I am aware, that 

 has been found in the United States belonging to this genus. 



Oimnatolampis hrevipennis, sp. nov. 



Elytra and wings shorter than the abdomen, green; dorsum rufous or 

 reddish-brown, and a black stripe on the sides of the pronotum. 



Female. — Tip of the vertex prominent in front of the eyes, diamond- 

 shaped and slightly indented in the middle; eyes closely approximate 

 above, j)rominent ; face suboblique; frontal costa deeplj" sulcate through- 

 out, reaching to the clypeus, parallel ; lateral carina3 subdistiuct and 

 nearly parallel. Pronotum subcylindrical, scarcely expanding pos- 

 teriorly; sides nearly parallel ; median carinas subdistinct; lateral cari- 

 nae obliterated; posterior transverse incision distinct, situated behind 

 the middle, about two-thirds the distance from the front; apex obtuse- 

 angled, rounded at the point. Elytra and wings extend over about 

 two-thirds of the abdomen. 



Color. — General color green, with the following markings: Fastigium, 

 a central spot in the face, a stripe along the middle of the pronotum; 

 the dorsal portion of the elytra (closed) and a dorsal stripe on the abdo- 

 men rufous; a narrow stripe along the external margin of the posterior 

 femora, and the entire anterior and middle femora bright coral-red. A 

 black stripe on each side of the pronotum extendingback only to thepos- 

 terior transverse sulcus ; it is sometimes interrupted by a yellowish and 

 reddish spot near the i)osterior end, and is usually bordered below by a 

 narrow yellowish or orange stripe. Antennae bright rufous except the 

 basal joint, which is green. Posterior tibiae green ; spines same color, 

 except the tips, which are black. 



Male. — Differs from the female only as follows: Is smaller; the anterior 

 and middle transverse incisions of the pronotum more distinct; elytra 

 and wings nearly as long as the abdomen ; subanal plate strongly curved 

 upward and somewhat pointed at the apex. Prosternal spine in both 

 sexes robust, somewhat conical. 



Dimensions. — 5 , Length, 0.90 inch ; elytra, 0.48 inch ; posterior femora, 

 0.52 inch; posterior tibiae, 0.48 inch. S , Length, 0.70 inch; elytra, 0.37 

 inch; posterior femora, 0.44 inch. 



Taken in Kew Jersey in August, and communicated to me from Pro- 

 fessor Uhler, through Professor Glover. A specimen in Lieutenant 

 Wheeler's collection fromlSTevada resembles this somewhat closely; but 

 as it is alcoholic, I cannot compare colors.
