INSECT NOTES. 



A new kermes, Kcrmes hranigani, was collected by Mr. E. J. Branigan and the 

 writer at the Bath mine, near Forest Hill, Placer County, Cal., November 22, 1913, 

 on the interior live oak (Qtiercus chrysolepis). The species was named after Mr. 

 Branigan by George B. King of Lawrence, Mass. — E. O. EssiG. 



The ladybird beetle, Psijllobora tcrdnta Lee. was found feeding upon orchard mites 

 on March 20th. in the neighborhood of Shively. Humboldt County. It occurred very 

 comTionly on some apple trees infested with the brown mite, Bryobia pratensis and 

 the citrus red spider, Tetranychus mytilaspidis. — Geo. P. Weldon. 



Tipnla simplex Doane, kindly determined by Professor R. "W. Doane of Stanford 

 Univer.«ity, was abundant in Sacramento the first two weeks in March. — E. J. Vosler. 



The milkweed bug, Oncopcltus fasciatus, has been received in considerable numbers 

 fi-om FA Oorado and Lake counties. In the winter time this species collects in large 

 colonies and growers have generally believed it to be destructive to the particular 

 plant upon which it congregates. To our knowledge it feeds only upon the species of 

 milkweed (Asclepias sp.). — E. O. EssiG. 



The rosy apple aphis, Aphis sorbi. is of common occurrence on apple and pear 

 foliage in orchards that have recently been visited in Humboldt, Shasta and Tehama 

 counties. This is becoming one of our very worst species of plant lice — Geo. P. 

 Weldon. 



The pine leaf scale, Chionaspis pitiifoliw, was found occurring in great numbers 

 upon the yellow pine. Pinus ponderosa, at Portola, Cal. The adult insects are at this 

 time of the year all dead but under the shells were found masses of eggs. — Leroy 

 Childs. 



The citrus red spider, Tetfoni/chus unitildsnidis Riley, and the brown or almond 

 mite, Bryobia ])r(ttcnsis Garman, have both been taken working together on apple 

 trees in Humboldt County. In the case of the former this appears to bo the first 

 authentic report of its presence in this county. — Geo. P. Weldon. 



The Italian pear scale. Epidiaspis piricola. has been recently taken on the moun- 

 tain liolly ( Hctcro)ncl(s arbutifolia) , at St. Helena, Butte County, Cal. This instance 

 .''liows the adaptability of foreign pests to establish themselves on distantly related 

 host plants in the countries in which they have been introduced. — Leroy Childs. 



A recent infestation of pear thrips, Euthrips pyri, was found in an orchard near 

 Stockton, San Joaquin County. This is the first official record of the pest in the 

 above county. — Geo. P. Weldon. 



The tanbark oak scale, Asuidiotus drnsiflorrr Bi-cmmer, was taken March 5, 1914, 

 by tlie writei- at \'alley Spring. Calaveras County, on the foliage of the interior live 

 oak (Quercus chrysolepis). Chionaspis qnercus Comst. was also collected on Quercus 

 chrysolepis at Valley Springs, Cal., March 5, 1914. — E. O. Essig. 



The codling moth, Carpocapsn poinonrlla, is mostly in the pupal stage at the 

 present time, April 4th, in Shasta and Tehama counties. This fact was determined 

 by observations in apple orchards during a recent visit to those counties. — Geo. P. 

 Weldon. 



The greasewood eriococcus, Eriococcus adenostomw Ehrh., was taken on grease- 

 wood or chemiso (Adenostoma fasciculatum) at Valley Springs, Cal., March 5, 1914. — 

 E. O. EssiG. 



The clover aphis, Aphis bakcri Cowen, was taken on quince foliage in Shasta 

 County near Anderson during a recent visit to that section. This aphis occasionally 

 becomes of considerable economic importance on fruit trees, especially apple and 

 pear. It sometimes works in the blossoms and may cause serious injury. — Geo. P. 

 Weldon.
