On some Acridioidea from Puerto Bertoni, Paraguay. 



BY LAWRENCE BRUNER, University of Nebraska. 

 The following named locusts were submitted to the writer 

 recently for determination. They were taken by Arnold de 

 Winkelried Bertoni, of Puerto Bertoni, Paraguay. Although 

 the collection is a comparatively small one, it is nevertheless 

 of more than usual interest since it contains at least three ap- 

 parently new species. In it are also represented two or three 

 other forms of more than ordinary interest. 



Orphula pagana Stal. 



This species is represented by both sexes ( $ , No. 710 and 

 9 , No. 717). They are of the normal size and color. 



Orphula gracillcornis n. sp. 



A moderately robust, medium sized, variably colored insect 

 with long, slender and but little flattened antennae and in 

 which the wings are more or less smoky with all the veins 

 bright ochraceous. 



Head large, a trifle wider than the front edge of the pronotum, 

 shorter than the latter, the occiput and vertex ascendent, the latter in 

 front of the eyes about as wide as long (?) or a little longer than 

 wide (5), more or less acuminate in front, the lateral walls sharp 

 and bordered internally by a deep groove. Eyes fairly prominent, 

 more or less acuminate above, with their anterior edge almost straight, 

 about as long as that portion of the cheek below them, separated above 

 by a space fully twice as great as the width of the frontal costa be- 

 tween the antennae. The latter 18 or 19 jointed, rather elongate, in 

 the female about equalling the combined length of the head and the 

 pronotum, in the male almost a half longer or nearly as long as the 

 hind femora, the joints of the basal half flattened, of the outer half 

 cylindrical, in nowise ensiform as in the typical species of the genus. 

 Frontal costa prominent, a little expanding from the ocellus down- 

 ward and a very little contracting just above, quite deeply sulcate 

 throughout in the $ , but in the $ sometimes nearly plane between 

 the antennae. Pronotum a very little expanding posteriorly, the lat- 

 eral carinae fully as prominent as the median and parallel to the last 

 transverse sulci, beyond this point more widely separated, a little less 

 prominent and plainly divergent to the hind margin ; hind edge of 

 disk obtusangulate, the surface of the hind lobe both on the disk and
