The illustration this month represents two rare Hesperids, 

 which were described in Vol. I, p. 23, of Entomological 

 News. Owing to circumstances the figures could not be given 

 sooner. The plate represents the so called half-tone process 

 of photo-engraving invented by Mr. Ives, of this city. The 

 plate was made by the Crosscup & West Company of 911 Filbert 

 Street, Philadelphia. In previous issues we have presented a 

 number of plates made by the Crosscup & West Company, and 

 it can be readily seen how well adapted the method is for illustra- 

 ting objects in this branch of natural history. Perhaps the greatest 

 advantage of the method is its comparative cheapness. The older 

 plan of lithography is an excellent one, but it is a luxury that can 

 only be enjoyed by the wealthy, as it necessitates the employment 

 ot an artist to make the drawings, and a lithographer to do the 

 lithographic work and printing, all of which are expensive. A 

 plate by the Ives process can be made from a good photographic 

 print of the object, but it is best to have it made from the nega- 

 tive when possible. If the photograph is made on one of the 

 new orthochromatic dry plates, the true color values of the ob- 

 ject will be obtained. One of the great drawbacks to the study
