sparrows dominate and exclude the native birds. All sorts of trees are 

 attacked. The insect has also spread to Staten and Long Island, and in 

 June and July is attracted in large numbers to the electric lights. 

 Radical measures are out of question. Palliative measures are, during 

 the dates of flight provide electric lamps in parks and shaded streets 

 with pans below with enough oil to kill the insects that are attracted and 

 fall into them.

Series MICROPTERIGIDES. 



In this series we have a remnant of ancient conditions, the two pairs of wings 

 being held together by a "jugum" or fold at the base of the fore-wings, as 

 occurs in the order Trichoptera, from which the Lepidoptera are derived. The 

 two pairs of wings are similar in size and venation, and are fastened to a loose- 

 jointed body, to which are attached a minute head and a long cylindrical 

 abdomen. 



The Hepialidce are large or very large, known as "ghost moths" from their 

 peculiar hovering silent flight. The Micropterygida: are small or very small 

 and also very rare, no specimen having been taken in New Jersey by any col- 

 lector, though I have no doubt that two or more actually occur with us.
