Plate VII represents the so-called "Owl Butterfly." This 

 individual specimen is Caligo atreus, and flies in America in the 

 Equatorial region. The underside photographed, looks very 

 much like an owl, the ocelli representing the eyes, and the various 

 shadings of brown representing the feathers. Insect collectors 

 frequently represent the body of the owl by other lepidopterous 

 insects, or in some cases brilliant Coleopfera, and use a species 

 of Caligo for the head, thus making a pleasing picture. There 

 are about twenty-five species in the genus, and they are all fine, 

 large insects, some of them very beautiful, but not so brilliantly 

 colored as the allied genus Morpho. They fly in Mexico and 

 Central America, and in Tropical South America. They are 

 represented in the East Indies by an allied genus, Thaumantis, 

 which also contains large and beautiful butterflies of a dozen 

 species. The specimen represented is, unfortunately, somewhat 

 broken, but shows the character of the underside of the fly very 

 well. This also shows the utility of the orthochromatic process, 

 as this species has colors on the underside which would not be 

 shown in an ordinary plate. 



This plate, like others we have given in the News, was made 

 by the Crosscup & West Engraving Company of Philadelphia,
