COLEOPTERA OF SOUTHERN CALIFORNIA. 153 



Chlamys. A specimen taken at Palm Springs in 

 April, it has not been possible to place with certainty; 

 it is very probably undescribed. 



Exema. E. conspersa is common in most localities; 

 taken by sweeping. 



Cryptocephalus. C. sanguinicollis is rather common 

 from March to May; Pomona, Pasadena, San Diego, 

 etc. ; the variety nigerrimus has not yet been seen from 

 our region, but it occurs near San Francisco, though 

 rarely: castaneus is not rare at Pomona during May and 

 June: spurcus is rather rare; I have seen specimens 

 from Pomona in July, and San Diego in August. 



Pachybrachys. P. analis, rare; Arrowhead Springs 

 and San Diego, late in May: pubescens (of which circum- 

 cinctus and viduatus are synonyms) is quite common on 

 willows during March and April: hybridus, moderately 

 common; Pomona, Pasadena, San Bernardino, San 

 Diego, etc.; May and June; taken by sweeping weeds 

 and bushes near streams and by roadsides: ccelatus, San 

 Diego, Yuma, Pasadena, Pomona; June: livens, Yuma, 

 Pomona, San Bernardino Mountains; May to October; 

 on Salix: lustrans is said to inhabit Southern California: 

 melanostictus and signatifrons are from the State, with- 

 out definite locality: donneri, recorded from Utah and 

 Lower California; it is, therefore, probable that it is to 

 be found in our district; I have seen specimens from 

 Yreka in this State. 



There are many undescribed species in my collection, 

 from various parts of the State, but most of them from 

 the south. 



Diachus. D. auratus is everywhere plentiful: erasus, 

 not rare about San Francisco (Marin County).
