Bruner reports the species also from Nevada and Arizona. 



Palmer fcmnd this species on grassy slojies, beside brooks. 



The form cniiima appears to be the only one found in the northern 

 part of the range of the species north of central Calitornia, and the 

 form (oUa^fs is rtirely met with anywhere. 



The iV rent forms have not been taken //* coitn with eacli other, so 

 far as I know. The form juvundus besides having very short tegmina, 

 is noticeably smaller than the otliers. 



I can scarcely think the tbrm collaris to be the insect described by 

 Thomas as Caleopteuiift [sic] ffavolincatua,^ as Bruner has supposed. 

 Thomas's description very poorly tits it; he makes no mention of the 

 tumid prozona, and he states, both here and subsecpiently,- that it 

 closely resembles Mehinoplus sprrtusy and that the ]>osterior margin of 

 the subgenital plate of the male is notched, whereas its general appear- 

 ance is very different indeed from M. sprctus; so much so that it can 

 hardly be believed that anyone would select it for comi>arison ; nor has 

 the apical margin of the subgenital i)late the faintest sign of any 

 emargination. Thomas's specimen was derived from Crotch's collection 

 in the Museum of Comparative Zoology; Crotch collected OedaleouotKft 

 enigma coUaris in central, not southern, California, whereas Tho.ias 

 gave his C. JiavolineatuK from southern California. Thomas's description 

 does not at all tit any species from southern California which has come 

 under my notice, and until such a form occurs his name should go for 

 nothing — at least until the Acridian fauna of that region is fairly well 

 known.
