prove the most satisfactory method of preventing injury that could be de- 

 vised. The specially interesting series of experiments were those made 

 with bacterial diseases. Quite a number of disease germs were cultivated, 

 but the efforts made to inoculate the Boll worm were in all cases practical 

 failures. This accords very well with what has been observed in other 

 cases, and it lends weight to conclusions that have been arrived at, that 

 msect diseases depend too much upon conditions which are not under the 

 control of man to be at any time considered as reliable, except in very 

 peculiar instances.

ENTOMOLOGICAL GLEANINGS FROM ALL QUARTERS 



OF THE GLOBE. 



[The Conductors of Entomological News solicit, and will thankfully receive items 

 of news, likely to interest its readers, from any source. The author's name will be given 

 in each case for the information of cataloguers and bibliographers.] 



To Contributors.— All contributions will be considered and passed upon at our 

 earliest convenience, and as far as may be, will be published according to date of recep- 

 tion. Entomological News has reached a circulation, both in numbers and circumfer- 

 ence, as to make it necessary to put " copy" into the hands of the printer, for each number, 

 three weeks before date of issue. This should be remembered in sending special or im- 

 portant matter for certain issue. Owing to low subscription rate, " extras" will be charged 

 for, and when they are wanted, it should be so stated on the MS. along with the number 

 desired. The receipt of all papers will be acknowledged. — Ed. 



Dr. J. E. Talmage, of Salt Lake City, Utah, disposes of the assertion 

 often made that no living thing can exist in the waters of the Great Salt 

 Lake. He records the presence of Artemia fertilis Verrill ; larvae of 

 Tipulidae, probably Chirotiomus oceanicus Packard; a species of Lcrrixa^ 

 probably C. decolor Uhler; and lastly the larvae and pupae of a fly Ephydra 

 gracilis Packard. 



" Hitherto the two groups Macro- and Micro-lepidoptera into which 

 butterflies and moths have been divided have been characterized by the 

 former including all the large and conspicuous species, and the latter only 

 containing small and inconspicuous moths. Dr. Chapman, in a commu- 

 nication to the Entomological Society of London, has endeavored to raise 

 the Micros in general favor by transferring to that group .several of our 

 finest moths. According to him the pupa of the Goat-moth ( Cossus lig- 

 niperda) possesses all the characteristics of a typical Micro-lepidopterous 

 pupa, and for a similar reason the genera Sesia, Zygcsiia, Procris and 

 Hepialus should be placed among the Micros.'' — Exchange. • 



Recently my attention was called to a cocoon which was found in a 

 shell of the snail known as Helix albolabris, collected at Lake Hopat- 

 cong, New Jersey. Thinking the cocoon to be that of one of the dipter-
