COLEOPTERA OF SOUTHERN CALIFORNIA. 93 



perplexus has been taken at Castle Crag (Fenyes): hornii, 

 recorded from the "Pacific States" by Jayne, but I 

 have seen no specimens from California; it is rather 

 frequent in Arizona, and it is likely that it may occur 

 in the adjacent desert region of California. 



Trogoderma. T. ornatum, common and widely dis- 

 persed: sternale, much rarer; I have taken a single 

 example on Catalina Island. 



Anthrenus. A. scrophularicv and A. verbasci are both 

 abundant everywhere on flowers; the latter has on one 

 occasion been reared from larvae found in one of my 

 duplicate boxes. 



Cryptorhopalum. C. apicale, common on blossoms of 

 willow in April: bcdteatum, much scarcer; on flowers, 

 Pomona: ruficorne, two examples; Pomona and Yurna. 

 An undescribed species is not rare at Pomona and 

 Pasadena. 



Orphilus. 0. niger is common nearly everywhere on 

 flowers. 



HISTERID.E. 



Hololepta. H. yucateca is said by Blaisdell to be 

 rather plentiful at San Diego from May to November, 

 in decaying fruit of Cucurbita, Echinocactus viridescens, 

 and leaves and stalks of Opuntia occidentalis. I once found 

 a dozen or more examples in a decaying flower-stalk of 

 Yucca ivhipplei, near Pomona in June. These latter were 

 apparently the form described by Blaisdell as pervalida, 

 and are easily separable from Arizona specimens of the 

 typical yucateca, and it is not unlikely that Blaisdell's 

 name will be restored to specific standing. H. cacti is 

 abundant at San Diego in decaying cacti, and is fre- 

 quently taken from beneath bark of decaying and water- 

 soaked wood of the willow (Blaisdell); I have never seen
