for it the name Limothrips allii. Remedies for all the insects are given, 
that for the Onion Thrips being kerosene emulsion in the usual propor- 
tions thrown forcibly upon the plants, care being taken to thoroughly 
wet the axils of the leaves where the young congregate. He advises 
making the application in the evening or the early morning, when the 
mature forms are more sluggish than in the heat of the day. 
Alabama Station, Bulletin 45.— Bulletin 45 of the Alabama Station (June, 
1893), by Prof. J. M. Stedman, is still another republication of well- 
known facts about common insects and remedies, and will serve a very 
useful purpose in furnishing the farmers of Alabama with data for the 
recognition and treatment of insects which, from lack of circulation of 
older publications, have not been accessible to them hitherto. 
Imported Beneficial Insects. — We have had little to say in INSECT 
Life as to the results of Mr. Koebele's last mission to Australia and 
the status of the imported insects, though we have endeavored to 
record every fact of importance connected with these insects. As the 
mission was undertaken under the joint auspices of the State Board of 
Horticulture and this Department, we recently instructed Messrs. 
Coquillett and Koebele to make a thorough examination of the colonies 
of imported insects, and report. It will be noticed from their reports, 
published in this number, that the insects from which the best results 
were expected, as indicated in previous numbers of Insect Life (viz, 
Orcus chalybeus and 0. australasice), seem to have increased at but one 
of the points at which they were colonized, and even here very slowly, 
while another species, of which little has been said hitherto, namely, 
Rhizobius ventralis, was found by Mr. Koebele to have multiplied in a 
remarkable manner at Santa Barbara. 
We also publish a somewhat extended review of Dr. H. Eouzaud's 
important paper upon the life history of Erastria scitula, a European 
Lepidopterous enemy of the Black Scale, Lecanium olece. This insect 
we hope to import into this country in the near future, as, from all that 
can be gathered, it keeps the Black Scale effectually in check in parts 
of Southern Europe which, in climate, agree fairly well with that of 
Southern California.
