Paramastax magna Üiglio-Tos. 



Twenty-seven spécimens of a dull-orange winged locust are 

 placed here. They come from the same gênerai locality as all the 

 preceding. These spécimens vary considerahly in both size and color, 

 but the structure seems to be quite stable throughout the séries. 

 The sides of the meso- and metathorax, and the basal half of the 

 abdomen are provided in some spécimens with a more or less well- 

 defined longitudinal flavous band. No females are at band. The en- 

 larged segments at the apex of the male abdomen also vary somewhat 

 in their comparative width. 



Paramastax fascialis Saussure. 



I find a single male spécimen of a second Paramastax that 

 seems to be S a u s s u r e"s fascialis. It differs from the preceding in 

 its somewhat slenderer form, the narrower head which has the face 

 and cheeks pale flavous, as well as the sides of meso- and meta- 

 thorax and basal two-thirds of the abdomen, and in lacking the 

 orange tinge to the wings. Its locality label is identical with the 

 preceding species. 



Apioscelis gracilis Brunn er. 



One of the raost interesting insects of the entire collection is 

 Äjnoscelis gracilis Brunn er von Watt. It is represented by 

 eighteen spécimens, two mature males, two female nymphs and four- 

 teen mature females. These were all taken at Iquitos, in north-eas- 

 tern Peru, durmg February, 1907. 



Orphulella punctulata de Geer. 

 A pair of thèse locusts were captui'ed at the locality already 

 cited by longitude and latitude. Judging from the scarcity of mate- 

 rial at band this must be a rather rare insect in the région where 

 taken. 



Orphulella peruna, nom. nov. 



Zonocerus? bilineatus Scudder, Proc. Bost. Soc. Nat. Hist., 

 xvii, p. 268 (1875). 



There are about a score of individuals at hand, Coming from 

 the same locality, of a second species of tlie genus Orphulella. 

 These appear to belong to the insect described by Samuel H. Scud- 

 der as Zonocerus ? bilineatus, and later referred to Orphulella
