NOTES AND NEWS. 



Aspidiotus rapax, a scale-like insect, has recently been re- 

 ported for the first time as occurring on the fi"uits of the orange 

 and the lemon in Southern California. 



A fine specimen of a Cycad was discovered in some gravel from 

 the bed of the North Umpqua river, near Roseburg, Oregon, by 

 Mr. Russell, of Yoncalla, Oregon. 



The Oregon Alpine Club has for its objects the acquirement of 

 information about the rivers and mountains of the northwest 

 coast, and relating to the geological formation, mineral resources, 

 and the fauna and flora of that region, together with the forma- 

 tion oi a museum. Its membership already includes hundreds 

 of the best learned men and women in the State, and other lo- 

 cahties may profit by its example. We hope to publish the pro- 

 ceedings of this and other societies as they may be furnished. 



The hop crop of Oregon and Washington for 1890 was nearly 

 60,000 bales, valued at $1,800,000, while the loss sustained by 

 this crop from the hop louse (Phorodon humuli) is estimated as 

 fully one-fifth of that amount. The ability to destroy $360,000 

 worth of crops in a single season renders this eastern pest, ap- 

 parently so insignificant in itself, worthy of careful study and in- 

 vestigation as to methods for its destruction. 



Coloradia pandora, the large moth which was attracted the 

 past season by the electric lights in southern Oregon in such vast 

 numbers, was originally described from Colorado (whence the 

 name) by Chas. A. Blake, one of the older members of the 

 American entomological society of Philadelphia. The larva 

 (presumed to be of this species) has lately been described as fol- 

 lows, from a specimen found feeding on sage brush in Montana 

 by Mr. Wiley: Mature larva all black, with shiny spines which 

 sting the hand like Hyperchiria io. Pupa somewhat resembles 

 that of H. io, but smaller, and less robust, nearly black.
