all of which except as noted below are from the more 

 northern parts: obliterates, soror, plagifera, rubida, sub- 

 argentata, impura, vexatrix, mattheivsii, grossa, central 

 and northern Sierras; propinqua, Kern River; carbonata, 

 dehiscens, sanguined, Icetifica (these last two rare at 

 Kaweah, Tulare County) (Hopping), common farther 

 north; quadrillum, chrysocoma, dolorosa, behrensii, Ala- 

 meda County; scripta, gnathoides, cubitalis. Several un- 

 described species exist in collections. 



Ophistomis. 0. ventralis, "So. Gal.;" El Taste, Lower 

 California. 



Ipochus. 7. fasciatus is not uncommon under bark, 

 and by beating, especially Rhus. Blaisdell reports 

 larvae taken from the wood of Rhus integrifolia at Coro- 

 nado, and Rhus laurina at Poway. Larvse have been 

 found by Coquillett in dead and dry apple twigs. The 

 beetles are abroad from February to Sept. 



Monilema. M. spoliatum has been taken by Mr. W. G. 

 Wright, exact locality not stated. 



Monohammus . M. maculosus is not rare at Lake 

 Tahoe (Fenyes) and north. 



Synaphceta. S. guexi, rare at Pomona and Pasadena, 

 March arid April; it has been bred from dead limbs of 

 sEsculus calif ornica, by Rivers. 



Ccenopceus. C. palmeri has been taken in numbers at 

 San Bernardino by Mr. W. G. Wright; breeds in Opuntia. 



Hyperplatys. The form of aspersus described by 

 Casey as californica, and which according to Leng is 

 only a variety of Say's species, is not unfrequently 

 taken about San Francisco. I have myself found it in 

 Marin County in August.
