NO. 1403. ORTHOPTERA FROM SOUTHERN ARIZONA— CAUDELL. 463 



niarg-iii of the elytra. It corre.spond.s with the variety tiigrlcans of 

 //. hoUiaria, and may be called //. ajxieJui var infmcata. 



A typical male (vpacha^ also taken \ry Kuiize at Phoenix, on May 13, 

 i.s below the record in size, measuring- as follows: Lenoth of elytra, 

 12 mm.; pronotum, 3.5 mm.; width of pronotum, 4. .5 mm. 



YERSINIA SOLITARIA Scudder. 



One specimen, apparently immature, Huachuca Mountains, August 

 13. 



This species occurs also in New Mexico, one of the specimens 

 recorded as Litajieutiua minor by Scudder and Cockerell" being this 

 species. I also have it from Las Vegas Hot Springs, New Mexico, 

 August 11, and Dinnnit Lake, New Mexico, August 21, all collected 

 by Cockerell. 



LITANEUTRIA MINOR Scudder. 



There are specimens of l)oth sexes in the collection of the U. S. 

 National Museum. From a study of Scudder\s original specimens it 

 is seen that the four species now contained in our lists are very nearly 

 allied to each other. (Jhscura and pacijica are scarcely distinct from 

 wln<>'t\ and lorealis is retained with much doubt, being known onl}^ 

 from the female, and separable from tvpical minor only b}^ the 

 smoother pronotum, a variable character. These nominal species 

 are separable as follows: 



1. Wings of the males without a sul)basal fuscous spot pacifica. 



Wings of the males with a sub))asal fuscous spot 2. 



2. Wings of the males quite deeply fuliginous throughout obscura. 



Wings of the males, aside from the subbasal fuscous spot, lightly fuliginous 3. 



3. Pronotum roughened in the female minor. 



Pronotum smoother in the female horealis. 



Typical minor^ represented in the U. S. National Museum by six 

 males and six females from Colorado, Arizona, and California, has the 

 wings of the males lightly fuliginous, rareh^ if ever completely hya- 

 line. This infuscation is variable and merges into the ohscvro type. 



Ohxrura, represented in the national collection l)y four males and 

 four females from Arizona and California, has the wings of the males 

 whollv infuscated more deeply than in typical ininor. The elytra is 

 also usually much darker and the veins more distinctly marked with 

 black than in minor. One specimen from California, however, has the 

 elytra light colored as in mi nor ^ and this specimen has the anal ara^ of 

 the elytra infuscated at the base. 



Pacijica^ not represented in the collection of the U. S. National 

 Museum, has the wings of the males feebly and uniformly fuliginous, 

 the subbasal fuliginous spot not represented.
