SPHIKX CHIONANTHI. 103 



came forth on the wing July 20th. It is not a 

 common moth. 



" Of those insects "which go into the earth, and 

 breed twice in the year, it is best to procure the 

 spring caterpillars, which are much more likely to 

 survive, the autumnal ones commonly dying in chry- 

 salis in the winter." 



On the same plate with the preceding caterpil- 

 lars, we have figured a very beautifully marked 

 larva (fig. 3) of an American species of Humming- 

 bird Hawk-moth, described by Abbot and Smith 

 under the name of Sphinx Ganrcc. It is nearly re- 

 lated to the S. Medea and S. (Enothercv of Fabricius. 

 The moth has the wings dentated ; the anterior pair 

 olive-green, with two whitish transverse streaks, 

 and a discoidal small rounded spot of the same 

 colour; the hinder pair ferruginous, with a pale 

 streak exteriorly. The caterpillar feeds on the 

 gaura (Gaura biennis) in the month of May. The 

 moth is rare in Georgia and most other parts of 

 America, and in its habits seems closely to resemble 

 our own Humming-bird Hawk -moth.
