material sent him foi' the ])rivileg(' of retaiuing such specimens as may 

 be needed for description or for completing the collection of the U. S. 

 National Musenm. We earnestly hope that those of our readers who 

 are sufficiently interested will, by complying with this request, help 

 themselves, Prof. Smith, and Lepidopterology; for every encouragement 

 should be given to those who have the time and the ability to do good 

 monographic work, which is the chief means by which our science is 

 ndvanced along systematic lines. 



PH^ISM IN INSECTS. 



In connection with the exhibition of dark specimens of Zygmna 

 minor, at a recent meeting of the Entomological Society of London, 

 which were not representatives of complete melanism, Mr. J. Jenuer 

 Weir suggests the use of the word plmeism as a correct term to apply 

 to snch departures from the normal coloration of the species. 



CAUTION TO HOP-GROWERS. 



Apropos of what has recently been said in these pages regarding the 

 superiority of the kerosene emulsion over the quassia chips, we quote 

 the following editorial from the California Fruit Grower of August 6: 



Smooth agents are said to be reaping quite a harvest from the Washington hop- 

 growers in the sale of quassia chips and other alleged remedies for the Hop Louse. 

 Hop-growers would do well to seek siich information as they need from responsible 

 sources, such as the experiment stations, or reputable journals, rather than give 

 their confidence and good money to wholly irresponsible traveling agents. 



A NEW SIMULIUM. 



A new Simulium allied to the notorious Buffalo Gnat of the South is 

 reported from southern New Mexico by Mr. C. H. T. Townsend, who 

 states that it breeds in the Eio Grande, issuing during May and June. 

 These gnats are a great annoyance to man, more so apparently than to 

 animals, and many persons are stated to be so susceptible to them as 

 to preserve through the gnat season a chronic inflammation of the ex- 

 posed parts of the face and neck resulting from the repeated bites which 

 in some instances give rise to sores. The inclination of the gnats to 

 flight increases with the advance of the season, but they disappear with 

 the falling of the water to its normal level in the rivers. The habits 

 and early stages have not been investigated, and the female fly, com- 

 prising the biting swarms, only has been studied. The species is de- 

 scribed as ^imidium occidentalis.
