A flea-beetle {Haltk-a folkura) was very injurious to grape foliage at 

 Socorro, N. Mex. 



A scale-insect {Chionasjm hiclavis) was found on orange twigs in 

 California, and in all probability was introduced from Tahiti. 



Stlctocephala inermis proved very injurious to young peach trees in 

 Tehama County, Cal. 



A new Icerya (the notorious Fluted Scale of California being the 

 only species of the genus hitherto known in this country) was reported 

 on Rose and other plants at Key West, Fla., and has been described as 

 I. rosce. 



An undescribed scale-insect of the genus Lecanium was found in- 

 festing grape-vines at Hudson, Ohio, and in Pennsylvania. 



1 have thus enumerated the additions to the list of injurious insects 

 that have incidentally come to the United States Department of Agri- 

 culture in this short period, and were I to enumerate those observed 

 by myself and assistants, or recorded by other workers and other insti- 

 tutions the list would simply weary you. 



NOTES ON THE LARVA OF AMPHIZOA.

In June, 1S91, while on a collecting trip to Great Salt Lake and the 

 mountains of Utah, Mr. E. A. Schwarz and the writer found AmpMzoa 

 lecontei, together with its larva, living in con- 

 siderable numbers in a cold, clear mountain 

 stream which supplies the city of Salt Lake 

 with its drinking water. Other streams from 

 the Wasatch Mountains emptying into the 

 basin of Great Salt Lake produced the imago, 

 and a single larva from American Fork 

 Canyon presents differences which may be ac- 

 cidental. In May of the present year a single 

 larva, indistinguishable from that of A. le- 

 contei, was found at Glenwopd Springs, Colo., 

 at the junction of the Roaring Fork with the 

 Grand River. A few weeks later the larva 

 of AmpMzoa iusolens, with the imago, was 

 found by Mr. Schwarz in the ice-cold waters 

 of a mountain torrent at Korth Bend, in the 

 Cascade Mountains of British Columbia. A 

 careful comparison of the larvae from British 

 Columbia with those from Utah and Colorado 

 to reveal any differences beyond the limits of individual variation
