Bostrychus. — A single specimen of B. calif oo^nicus was 

 secured in the San Bernardino Mountains in July. 



Amphicerus. — A. fortis, Colorado River: pundipennis, 

 Riverside, Redlands, Pomona, Long Beach; June to 

 October; often taken at electric lights: teres, Yuma; 

 unknown to me. 



Dinapate. — D. wrighfii is a mammoth Bostrychide 

 known only from the canons leading up from the west- 

 ern borders of the Colorado Desert, at and near Palm 

 Springs, where it depredates on the Washingtonia palms 

 (NeoivaHhingtonia filifera). It was originally discovered 

 by Mr. W. G. Wright, and has since been found by 

 Mr. H. G. Hubbard, whose most interesting letters to 

 Mr. E. A. Schwarz, describing the rediscovery, with 

 much information concerning the larval habits, have 

 been recently published by Mr. Schwarz. 



Dinoderus. — D. pacijicu.s, San Bernardino Mountains, 

 not rare: sobrinus, from the same locality; scarce: trun- 

 catus, "California" (Horn). 



Polycaon. — P. stoutii is common throughout maritime 

 Southern California; once taken in numbers from 

 beneath the loose bark of eucalyptus in early summer: 

 confertus is also widely diffused; it depredates on grape 

 vines. Of megalops two examples only have been seen, 

 one of which was taken at light at Pomona, September 

 25; the other is in the collection of Dr. E. C. Van Dyke. 



Psoa. — P. maculata and P. 4--^i9'>'>(ii'^<^ are both rare 

 insects in Southern California.

 trict from Yuma to the Coast: parvulus, rare, Pomona, 

 June: californiciis, Yuma (Casey): curtulus, described
