PARACORNOPS PARAGUAYENSE, new species. 



In color and general appearance very similar to the insect here 

 accepted as the loiujlpenne DeGeer, but ditfering- from that insect in 

 its much larger size and paler color. It also varies from Joiujlpenne 

 in having the lower lateral edges of the pronotum less sinuate, while 

 the prosternal spine in the present species is very long and slender as 

 compared with the shorter and rapidly tapering one of the other insect. 

 Frontal costa scarcely expanding between the antennn^, shallowly sul- 

 cate, and- with the carina not converging at the ocellus. 



Length of body, female, 33; of pronotum, 6; of tegmina, 28; of 

 hind femora, 16.5; of antennae, 8.25 mm. 



Hahitat. — San Bernardino, Paraguay, a single female collected by 

 the Avriter during the month of September. It was taken among the 

 rank grasses growing in an open glade near a lake. 



PARACORNOPS AQUATICUM, new species. 



General color above grass-green, on the sides and below greenish 

 yellow. Sides of head back of the eyes and upper portion of the sides 

 of pronotum and upper portion of pleura, together with a small basal 

 portion of the costal margin of the tegmina, washed with piceous, 

 which marking is most apparent in the male. 



Head of moderate size, in the male a trifle narrower, in the female 

 about as wide as the front edge of the pronotum, the occiput short; 

 e3^es fairly prominent in both sexes, the vertex about as wide (female) 

 or a little more than one-half the width of the frontal costa (male), 

 the fastigium short, broad, blunt, centrally gently sulcate; frontal 

 costa prominent above where it is somewhat narrowed, as it is also 

 below the ocellus, shallowly and broadly sulcate; the surface coarsely 

 punctate; punctuations of the face piceous, giving it the appearance 

 of being profusely freckled. Antenna^ filiform, about equal to (female) 

 or a very little longer than (male) the head and pronotum taken 

 together. Pronotum subcj^indrical, a little expanding on the hind 

 lobe, profusely and rather coarsely punctate; median carina percur- 

 rent, but not prominent; the anterior margin roundly advanced upon 

 the occiput, hind margin obtusangulate (male) or subrotund (female). 

 Tegmina rather narrow, their apex subacuminate as compared with 

 Jong'ipenne^ extending one-third (male) or one-fourth (female) of their 

 length beyond the tip of the abdomen. Hind femora rather robust 

 and long, surpassing the abdomen in both sexes; hind tibia? unusually 

 broad on their apical portion, the outer edge 7-spined. Prosternal 

 spine short, coarse, and blunt, slightly transverse. Last ventral seg- 

 ment of male abdomen short, the sides of apex provided with a blunt 

 tooth; the supraanal plate marked with two narrow subbasal lines and 

 two black dots.
