 Insect Life, iv, Nos. 1 and 2, October, 1891, pp. 32, 33. 



Short paper read before the "Washington meeting of the Association of Economic Ento- 

 mologists regarding the alleged difference between the emulsion consisting of kerosene ex- 

 tract of pyrethrum with soap and water and the emulsion prepared from an aqueous extract 

 of pyrethrum with soap and kerosene. Adduces a communication from Prof. J. McNeill to

 separate under above title. 



A systematic enumeration of the Lepidopterous insects composing the superfamily Tineina 

 hitherto described from North America. In a note (pp. 94, 95) the author points out the diffi- 

 culties in preparing a satisfactory list of Tineina with our present state of knowledge of 

 these insects. An "Addendum to the Tineina" (pp. 112-114) gives a generic synonymical

The author complains that valuable inventions and discoveries made by Government em- 

 ployes during investigations carried on by Government institutions can be appropriated and 

 patented by outsiders upon mere legal technicalities. As an instance of this sort the gas 

 treatment for scale insects is discussed.
