Melanoplus missionum 18 Scudder. 



A series of seventeen specimens of this species are in the collection 

 before us, all taken in a comparative small area. The localities repre- 

 sented are the following: Arroyo Seco at Pasadena, one male, July 

 20, F. Grinnell, Jr., one female, August 1 ; Arroyo Seco, San Gabriel 

 Mountains, elevation 3,000 feet, October 8, F. Grinnell, Jr.; Altadena, 

 August 8, one male; Mt. Lowe, 4,000 to 5,600 feet, August 8, six 

 males, seven females. There is considerable individual variation 

 in size, specimens from the highest elevation on Mt. Lowe showing 

 the following extremes : 



& 

 mm. 



Length of body, 15.8 



Length of pronotum, . . . . 4.2 



Length of tegmen, 3.2 



Length of caudal femur, . . . . 10 . 2 



The exposed portion of the tegmina varies considerably in length, 

 in one case hardly more than half the average exposed area being- 

 visible. The general coloration shows considerable variation, ranging 

 from quite uniform greenish yellow to dull olive and ochraceous-buff 

 and vandyke-brown. The last mentioned type predominates, the 

 females, however, being much duller than the males. The yellow 

 type is represented by one female from 3,000 feet elevation in the 

 Arroyo Seco, while the single olive specimen is from the Arroyo Seco 

 at Pasadena. The yellowish postocular line is distinct in the majority 

 of the specimens and faintly indicated in the remainder. The femoral 

 bars are distinct in all the males and faintly indicated in all the females 

 except the greenish-yellow specimen, which also has the caudal tibia? 

 yellowish externally and glaucous internally instead of nearly uniform 

 glaucous as in the others. A more or less distinct yellowish pregen- 

 icular annulus is present in the majority of the series. 



Specimens were never taken in numbers, but single individuals 

 were occasionally noticed. 



The only previous record of the species is from Los Angeles. This 

 reference probably should stand as Los Angeles County. 

 Melanoplus fuscipes Scudder. 



Two females of this species were taken in the San Gabriel Range 



18 The senior author's (Edqleonotus truncatus (Ent. News, XVIII, p. 353) from 

 the San Gabriel range near Claremont, California, is a synonym of this species.
