Report OQ an interestiüg collection of Locusts from Peru, 



The loUowing iiamed locusts are contained in a collection iiiade 

 by Mr. N. I к n II i к V in Peru, South America, during- tlie year 1906, 

 aiul later submitted to the präsent writer for deternnnation and 

 study. Altliough only forty species are contained in this collection at 

 least a dozen of them appear to be new to science and are de- 

 scribed herewith. It is to be reg-retted that several of the new forms 

 are represented by single sprecimens, hence only one sex can be 

 characterized. It is especially unfortunate that it has been necessary 

 to estahlish three new gênera on single individuals. Still, thèse in- 

 sects are so manifestly distinct fi'om all hitherto described foi'ins 

 that it was out of the question to try to include them in known 

 gênera. 



It is to be hoped that further collections Coming from the 

 same and other Andean régions of the upper Amazon in Peru and 

 Ecuador will disclose the missing sex and add still other forms wliicli 

 will assist in determining the affinities of two or tiiree of those now 

 described. The types of the new forms are to tte found in M-r Ikon- 

 n i к v"s collection at Moscow. 



Amorphopus notabilis Serville. 

 The collection contains l'ivc sjtocimens of this pecular flat-bo- 

 died locust. They were taken at a point in Peru 75^ and 17' west 

 IVoni (ireenwich and 11° and 8' south latitude. Tliey are typical. 



Otumba marcapata Hancock. 



A single male individual was taken at the sanie place as the 

 preceding species.
