 Since the specific name bilineatus was used for Stenobothrus hiline- 

 а1ия in 1862 M, and it has been shown subsequently that this latter 

 insect also belongs to OrphideUn, although as a variety or syno- 

 nym of A. aequalis Scudder, it becomes necessary to give it 

 another name, and périma is suggested. 



Toxopterus miniatus Bolivar. 

 This species is represented by eight spécimens, five maies and 

 three females. It also cornes froni the gênerai locality cited above. 

 The bright red wings of this insect must render it very conspicuous 

 among the other locusts of the région. 



Ommexecha brunneri Bolivar. 

 It is represented by four individuals, three females and a single 

 maie. They were collected during the months of October and No- 

 vember. 1906. The locality is the same as that from whichthe ma- 

 jority of the spécimens contained in the présent collection come. 



Tropidostethus bicarinatus Philip pi. 

 It is very interesting indeed to find tlie named species among 

 insects taken on the eastern slopes of the Andes mountains and so 

 mach farther to the north than where it was originally collected. 

 It comes from 7.5° 17' W and 11° 3' S. 



Prionolopha serrata Linn. 

 This large and attractive locust seems to be présent throughout 

 ail tropical South America at suitable localities. It is represented 

 by seven mature and three nymph spécimens. It does not differ from 

 individuals coraing from other localities. The material at hand was 

 taken at the locality already mentioned in connection with other 

 species. 



Tropinotus strigatus Bru ne r. 



This Tropinotus whicli I bave ealled strigatus, is represented 

 by a single maie from the gênerai locality situated on the east slo- 

 pes of the Andes to the eastward of Cerro de Pasco. It can be re- 

 cognized by ist rather slender form and gênerai cinereous color and 

 ])aler lengthwise strigate tegmina that lack maculations. There are 

 ten spines on the external margin of the liind femora and the pos-
