1922] Ball and Hartzell: Review of Orgerini 145 



Variety rhyparus Stal. 



(Plate XII, Fig. 15). 



This variety is characterized by its rather uniform testaceous color 



and appears to be one of the rarer forms. It has been found in the 



foothills around the Sacramento and San Jauquin valleys and extending 



over the range towards the Salton Sink as far as Cabazon. 



Variety clitellus n. var. 



Resembling var. rhyparus, large, obese forms with a testaceous color 

 sharply set off by the shining black elytra. 



Described from three examples from Santa Margarita, Chico 

 and Colfax, California. This variety was found with the pre- 

 ceding and appears to be a still rarer adaptation to these dry, 

 hot situations. 



Variety concordus n. var. 



Large, obese form with the females averaging from 5-6 mm., uni- 

 form dull fuscous above, with a slightly pearl-gray sheen. 



Described from two pairs from Cabazon, California, and 

 Ti Juana, Mexico. This is the common variety in southern 

 California extending from Visalia and Cabazon south and west 

 to Ti Juana, Mexico. 



Variety pajaronius n. var. 

 Small, rather slender, female not over 4 mm. in length, resembling 

 concordus above but much smaller and with the face much more fre- 

 quently transversely banded with light. 



Described from two pairs from Salinas and Watsonville, 

 California. This variety occurs on the Coast Range from the 

 Salinas Valley north to San Francisco and a pair were taken on 

 the eastern slope of the Sierra Nevadas near Le Grande, Oregon. 



Variety ventosus n. var. 

 Resembling pajaronius in size and form, dimorphic in color, the 

 female mottled fuscous and white, the central tablets of the pronotum 

 and scutellum almost creamy, the face trifasciate with light. Male 

 clear yellowish-white with a few fuscous spots on the lateral carinas of 

 the vertex. 



Described from three pairs from Mojava, California, taken 

 July 30. This peculiar form appears to be strictly confined to 

 the sparse vegetation of that windy and inhospitable desert 

 region. Most of the specimens were beaten from a low, spiny 

 white shrub.
