WINTER NUMBER 105 
Under ‘“‘Timely Notes” the presence of the Saddle-back Cater- 
pillar on trumpet vine at the Experiment Station was reported 
by Professor J. R. Watson. 
The principal paper of the evening, “Birds and Animals In- 
jurious to Farm Products’, was read by Mr. T. Van Hyning. 
Mr. Van Hyning reviewed the records of a number of birds, and 
it is his belief that but few are wholly injurious, most of them 
really being useful in reducing insects. Of mammals, the pocket 
gopher is the worst and a real parasite. Poisoned water is a 
remedy for rats in buildings. 
The second paper of the evening, by E. W. Berger, was a con- 
tinuation of the discussion on “Common Names of Insects” con- 
ducted at the previous meeting. The following principles were 
indicated as guides that may be followed by entomologists and 
others in the selection of common names: 
1. Select a name already in use by the growers or others. 
2. If there is no common name already in use, the scientific 
name may be translated wholly or in part. Thus we have Oak 
Ericoccus for Hricoccus quercus (oak), Flocculent Whitefly for 
Aleurothrixus floccosa, Bay Whitefly for Paralemodes perseae 
(bay), ete. 
3. Some well defined and readily apparent characteristics 
may be used; as Woolly Whitefly, Cloudy-winged Whitefly, Long 
Scale, Chaff Scale, etc. 
4. Sometimes the name of the person who described and 
gave it the scientific name is used as the common name; thus 
we have Putnam’s Scale for Aspidiotus ancylus (Putnam). Or 
the name of the town or locality from which an insect is known 
may be used as the common name; thus we have Jan Jose Scale 
for Aspidiotus perniciosus, Florida Red Scale and California 
Red Scale for Chrysomphalus aonidum and C. aurantii respect- 
ively. 
Scientific names of living things are recognized the world 
over. In other words, whenever an insect is described and given 
a scientific name, that is its name from Washington to Tokio, 
either way around the world. The fact that scientific names are 
written in Latin, either in Latin words or other words having 
the Latin endings, probably accounts for their ready acceptance. 
By using Latin as the language for scientific names, the compe- 
tition between the many other languages is avoided. lLinnaens, 
the noted botanist, first began the use of two latinized names for 
plants and animals nearly 200 years ago.
