A brown scale occurring on elms at Davis, Cal., has been determined by Geo. B. 

 King of Lawrence, Mass., as Eulecanium canadense (Ckll.). The writer has taken' 

 this scale at Clements, San Joaquin County, Sacramento, and received it from Tulare 

 and Fresno counties. — B. O. EssiG. 



Both adults and larvae of the alfalfa butterfly, Eurymus eurytheme (Boisd. ), are 

 at present very conspicuous in the alfalfa fields about Sacramento. — Lerot Childs. 



Serica alternata Lee. is reported as working upon the foliage of fruit trees in 

 Ventura County by R. S. Vaile. — E. O. Essig. 



Tetranychvs bimaculatus Hard., one of the common red spiders of fruit trees, is 

 doing great injury to the foliage of maples this year in the city of Sacramento. The 

 leaves on trees attacked by this pest are losing all of their green color, resulting in 

 the decided marring of the beauty of this popular shade tree. — Lerot Childs. 



A small, gray leaf beetle, Myochorus longulus Lee, was reported to Dr. E. C. Van 

 Dyke as having ruined thirty acres of cotton at Mexicali in April. — E. O. Essig.

 in Shasta County, near Redding. It is locally called the army worm, and has excited 

 considerable alarm by its devastations. — Geo. P. Weldon. 



A hairy scarabseid, Phobetus comatus Lee, has been received from H. H. Bowman, 

 who states that the adults feed upon the foliage of fruit trees in Placer County. — 

 E. O. Essig. 



A species of army worm was collected during the month of June in great quan- 

 tities at Forest Hill, Placer County. It was apparently omnivorous in its food habits, 

 as it was found feeding upon a large number of species of weeds, grass, clover, bushes, 

 and trees, many of which were defoliated. A considerable amount of damage was 

 reported to have occurred to vegetable gardens. Two species of parasites were 

 reared, a Tachinid and an Ichneumonid. Also a black species of Calosoma was 

 found feeding on the larvse. — E. J. Branigan. 



The thistle butterfly, Pyrameis cardui, was noticed in large quantities along the 

 Sacramento River, feeding upon malva, bull thistle and smart weed. Large patches 

 of these plants were completely defoliated during the month of June. — E. J. Branigan.

 Placer County. — E. J. Branigan. 



The red-humped caterpillar, Schizura concinna, has not been so abundant this

 parasites of wliich there are several, the commoner being a species of Ichneumonid, 

 a Tachinid and a Brachonld, apparently Apanteles. — E. J. Branigan.

 effects of this scale. — E. J. Branigan.
