ENTOMOLOGY. 61 



Temperature experiments as affecting received ideas on the hibernation 

 of injurious insects, L. 0. Howard (pp. 18-20). — According to the result 

 of experiments extending over a period of two years a change from a 

 temperature of about 18° F. to one of 40 or 50° and then back again 

 to a lower temperature, is fatal. 



Motes on certain species of Goleoptera that attack useful plants, F. H. 

 Chittenden (pp. 20-25). — The following insects are noted: Orsodachna 

 atra, on pear and cherry; grapevine colaspis (Colaspis brunnea), which 

 has been found on beans, clover, Le Conte pears, potatoes, corn, 

 tick trefoil, and the New Jersey tea plant (Geanothus americanus) ; 

 horse-radish rlea-beetle (Phyllotreta armoraciw), which has been taken 

 in Wisconsin and may travel eastward; Psylliodes punctulata, which is 

 found on rhubarb in the District of Columbia; corn and grass feeding 

 Clnctocneinas (Ghcetocnema pulicaria, G. conjinis, and C. parcepunc- 

 tata), which have been found upon corn and C. denticuhtta in Maryland 

 on barnyard grass; the locust leaf miner (Odontota dorsalis), the range 

 of plants liable to be attacked by which seems large and which has 

 been found feeding on red clover under locust trees, and also on the 

 hog peanut (Falcata conwsa) ; Ghelymorpha argils, found on the sweet 

 potato; Epicauta trichrus, also found on the sweet potato and on hedge 

 bindweed (Conrolrnlns sepium), and in Illinois on the may weed (Ma rata 

 [Anthemia] cotula) ; false rose chafer (Macrodactylus august at us), 

 which seems to prefer the black or sour gum (Xyssa multi flora), chest- 

 nut (Castanea dentata), oak, particularly chestnut oak (Quercus priuus 

 et al.) and sassafras, and has also been beaten from dogwood, hickory, 

 and persimmon, but the leaves of these did not appear to be fed upon 

 to any noticeable extent; and the potato-bud weevil (Anthonomus 

 nigrinus), found on the eggplant in Maryland. 



An experience with Paris green, T.D.A. Gockerell (p. 2o). — The author 

 notes that in the case of an application of Paris green to the peach, as 

 a remedy against Allorhina mutabilis, the poison which entered over- 

 ripe peaches passed into the circulation of the tree so as to affect 

 neighboring branches injuriously. 



The present status of the Man Jose scale in Michigan, W. B. Barrows 

 (pp. 27-30). — The scale occurs in the State in thirteen different local- 

 ities. The introduction of the scale into ( Ottawa County is traced 

 to stock received from New Jersey in 1890. As it winters in Ingham 

 and Ottawa counties, it is thought very likely it will winter safely 

 further north. 



Vernacular names of insects, G. P. Gillette (pp. 32-34). — A list of 

 common names is given with a view to improvement in orthography. 



Notes on Gape of Good Hope insects, G. P. Lounsbury (pp. 34-38). — 

 Among the insects noted as injurious in South Africa is the red- 

 winged locust (Acridiwm purpuriferarum), which has decreased in 

 numbers from attacks of a fungus disease identified with Empusa 

 grylli. Artificial propagation of the disease was tried, but owing to
