Jfdhltaf. — The colloctioiis made at Sapucay, Paraguay, by W. T. 

 Foster, and sent to both the U. S. National Museum and the writer, 

 contain a number of individuals of both sexes. It is also common in 

 portions of Argentina and Bolivia. 



STIRAPLEURA Scudder. 



Although no specimens of this genus are at hand, nor none appar- 

 ently have been reported from Paragua}', it is quite possible that 

 Stirapleura is represented in the country. They may be looked for 

 on sandy o})en country. Stintplevra variabilis Bruner, from Argen- 

 tina, is figured at hg. 2, on Plate XXXVI, in order that the genus 

 may be recognized if found. 



MELOSCIRTUS, ne^A^ genus. 



Related to Stenohotli nis and Bruneria., but differing from both of 

 these genera in a ruimber of respects. Rather below medium in size; 

 in the female with abbreviated tegmina and wings. The face, occi- 

 put, the disk, and sides of pronotum and meso- and metathorax pale 

 streaked. 



Female. — Head moderately large, a little wider than the front edge 

 of the pronotum. Eyes subpyriform, about as long as the cheeks 

 below them, separated above by a space twice the width of the frontal 

 costa between the antennai. Fastigium rather deeply sulcate and pro- 

 vided with a faint median longitudinal carina, meeting in front in an 

 obtuse angle; lateral foveolre small, about twice as long as wide, onlv 

 partially visible from above. Front viewed in prolile roundly oblirjue; 

 frontal costa fairly prominent, evenl\' divergent and continuous to the 

 clypeus, sulcate. Antenna^ tiliform, a little longer than the combined 

 length of head and pronotum. The latter short, a very little con- 

 stricted at middle, broadl}' rounded in front, obtusangulate behind; 

 lateral carina arcuate and greatly interrupted between the transverse 

 sulci, median carina fairl}' prominent throughout, cut by the last 

 transverse sulcus a little back of its middle; lateral lobes a little 

 higher than long, the lower edge rounded and provided on each side 

 near the hind margin with a more or less prominent, raised, pale- 

 colored tortuous carina. Tegmina somewhat abl)reviate, about half 

 as long as the abdomen, acuminate, the costal border a little ampliate 

 near the base, without an intercalary vein. Hind femora rather 

 robust, their tip coincident with that of the abdomen; hind tibia? pro-
