Super-family SPHINGOIDEA. 



These are the "hawk-moths," so called from their rapid darting flight, 

 and habit of remaining poised in the air for a time, in front of a flower. 

 They are usually crepuscular, flying in the early twilight, hovering over 

 deep flowers like petunia or evening primrose, into which they extend 

 their long flexible tongue to reach the nectar at the base; but some 

 species fly in the bright sun of mid-day. They are of moderate or large 

 size, robust build, with usually pointed wings, conic abdomen, and an- 

 tennae that are fusiform, prismatic and with a short, recurved tip. In 

 some species the tongue is nearly six inches in length when fully un- 

 coiled, but in others it disappears completely. 



The larvae are as characteristic as the adults, and most of them have 

 a curved horn on the dorsal segment of the end segment, or, in place of 

 it, a polished, eye-like spot. They look formidable, but are actually 

 harmless, and it is from their habit of sometimes resting with head and 

 anterior segments elevated, that they get their "sphinx" appellation. 



A few of the species are of economic importance, but as a rule they 

 are kept in check by their parasites and other natural enemies. All of 

 the caterpillars are susceptible to arsenical poisoning. 



Family SPHINGID^. 

 Sub-family MACROGLOSSIN^. 



These are the "humming-bird" hawk-moths, in which the wings are 

 partly transparent, the colors are metallic bronze or brown and yellow, 

 and the abdomen has lateral and terminal flattened tuftings. They fly in 

 the bright sunlight about flowers, favoring lilacs while these are in 

 bloom, and are often mistaken for true humming birds.
