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. — G. sanguinicollis is rather common 

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

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

 our region, but it occurs near San Francisco, though 

 rarely: castmieus 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: puhescenH (of which circwm- 

 cindus and vidiudiis 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: ccda.tus, San 

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

 Pomona, San Bernardino Mountains; May to October; 

 on Salix: lustrans is said to inhabit Southern California: 

 melanostidus and sif/mdifrons 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. aiiA-atits is everywhere plentiful: erasus, 

 not rare about San Francisco (Marin County),
