ing, sajj once a year, to discuss new discoveries, aud particularly to ex- 

 change experiences as to methods of work, whether iu field or laboratory. 

 Such a coming together of those engaged in kindred work aud the con- 

 sequent interchange of experience and intercommunion could not fail to 

 be productive of good both socially aud scientificall}". Economic ento- 

 mology has heretofore greatly suffered by the writings and pretensions 

 of those who have no sort of appreciation of its real value aud impor- 

 tance, but who, writing at second hand, upon subjects of which they 

 have no personal knowledge whatever, are just as apt to disseminate 

 error as truth. We should like to get an expression from those of the 

 readers of Insect Life interested in the work as to the desirability 

 aud feasibility of such a national organization, and particularly as to 

 how many could attend a meeting once a year in some one of our large 

 cities. 



Kerosene Emulsion— An Error corrected. — We have unfortunately been 

 misquoted of late relative to a statement made in the Introduction to 

 our 188 !J report. We there stated that where milk is not accessible a 

 satisfactory kerosene emulsion can be made with the white of egg 

 and a little sugar, and gave the most desirable proportions. We no- 

 tice, however, that Orchard and Garden for February, 1888, and other 

 journals on previous dates have published the entirely unwarranted 

 statement that " Professor Eiley has had the best results in fighting 

 scale insects with a kerosene emulsion prepared after the following form- 

 ula," quoting the white of egg and sugar recipe. Our position is thus 

 entirely misrepresented. 



It will be news to most entomologists to learn that the Wm. H. Ed- 

 wards collection of Ehopalocera has been purchased by the Rev. W. J. 

 Holland, of Pittsburg, Pa. Tlie collection of Dr. Holland, as thus en- 

 riched, is probably one of the largest as well as typically the most per- 

 fect collection of the Ehopalocera of temi^erate North America. In ad- 

 dition to the collection of Wm. H. Edwards it contains the entire collec- 

 tion of Mr. Theodore L. Mead, aud a large number of specimens derived 

 from Morrison, Wright, Behrens, Eicksecker, aud other collectors, in all 

 fully 8,000 specimens, representing the nearly 700 species credited to our 

 fauna. As an illustration of the richness of this collection, it may be 

 mentioned that Li)cwn% i)seudargiolus is represented by 256 specimens, 

 ranging in their distribution according to their localities from St.' 

 Michaels, Alaska, to southern Florida, and from Quebec to Arizona, 

 with a large series of bred specimens arranged according to pedigiee 

 from one brood to another, showing the lineage of the seasonal or 

 dimorphic forms. 



The Ehopalocera of other lands are well represented, notably by speci- 

 mens from tropical America, Africa, and Asia, and by fine suites of the
