Melanoplus herbaceus Scudcl. 

 Melanoplus pictus Scudd. 

 Melanoplus yarro-wii Thorn. 



This species is represented by eighteen specimens, several of 

 which are tinged with greenish. 



In a small collection of Arizona Orthoptera, made by Mr. E. 

 A. Schwarz some years ago, mostly in Madera canyon in the 

 Santa Rita Mountains, are some quite interesting forms. The 

 most interesting of these are here noted. 



Vates sp. 



An immature specimen belonging to the genus Vates occurs 

 in the collection. It is too young to permit of a specific determi 

 nation, but there is no doubt of its belonging to this genus. 



Litaneutria spp. 



In this collection occur six male specimens belonging to the 

 genus Litaneutria. They evidently represent two species, but 

 the condition in which the species of this genus have been left by 

 Professor Scudder's insufficient descriptions* makes their deter 

 mination impossible without an examination of the type speci 

 mens. 



Ischnoptera uhleriana Sauss. 



A male from Madera canyon is somewhat larger than those 

 commonly taken in the East, measuring 18 mm. in length of 

 elytra. 



Latindia sckivarzt sp. nov. 



Testaceous, head brown. Thorax transversely elliptical. Elytra long, 

 veined as in L. delicatula. Wings hyaline with an opaque infuscated area 

 beyond the middle of the costal margin, at rest reaching slightly beyond 

 the tips of the elytra. Cerci about as long as the pronotum, curved so 

 strongly downwards as to almost form a circle. 



Length, pronotum, 1.5 mm., elytra, 7 to 8 mm., width, pronotum, 2.25 

 mm. 



Type No. 6706, U. S. National Museum. 



Three male specimens from Madera canyon, Santa Rita 

 Mountains, collected June 8 and July 7, 1898. 



This species is very closely allied to L. delicatula, from 

 Guatemala, the main differences seeming to be the longer wings 

 and the less infuscated state of the under wings. 



Myrmecophila for mi car um Scudd. 



Two specimens of this species were taken in Madera canyon 

 with Camponotus sp. This seems to be the first published record 

 of any species of this genus being taken in Arizona.
