1911] Study of Caterpillars of Sphingidae 273 



Horn decidedly longer than head. With a subdorsal line, 

 and the normal obliques. Spiracles red with white ends 

 (agreeing with the Macroglossa group, Clarina, and some speci- 

 mens of Protoparce). Otherwise like Choerocampa. 



In A. versicolor the horn is nearly twice as long as the head, 

 thick and strongly down-curved; in myron it is shorter, straight 

 and conical, but apparently it is exceptionally variable in all 

 three species. 



Clarina. Horn only about as long as head; tubercles of 

 head very small and inconspicuous; otherwise wholly like 

 Ampeloeca, — with continuous subdorsal. C. syriaca, of Syria. 



Deidamia. Horn rather longer than head. Supraanal an 

 acute equilateral triangle. Spiracles pale with a black bar on 

 each side. Front full as wide as high. Body but little swollen. 

 Otherwise like Amplececa. 



C. syriaca and D. inscriptitm are marked almost exactly 

 like A. myron, but with evanescent obliques. 



Ampliion. Head irregularly roughened, without raised 

 isolated tubercles, squarish, as in related genera. Supraanal 

 as long as wide and acute; spiracles dark. Horn shorter than 

 height of head. Front full as high as wide, third ocellus much 

 enlarged (as in Clarina and Deidamia also). Body but little 

 swollen. Otherwise like the related genera (I, figs. 48 and 53.) 



Sphccodina. Body not at all swollen on the first abdomi- 

 nal segments. Head large, very rough in the last stage, but 

 without raised tubercles; in the next to last as in Ampelceca. 

 Front higher than wide, y height of head. Clypeus broader 

 than in Deilephi/a, etc. Labrum like Pergesa. Horn replaced 

 by a wart; in the last stage similar to that of Pholus, in the next 

 to last high, and cylindrical; before that surmounted by a slen- 

 der horn, which rises, not as in Pholus from its posterior side, 

 but from the middle. Supraanal wide. 



Proserpiiuts (Fig.- 3). Horn normal but rather short (gaurce) 

 or replaced in the last stage by an eyespot, which may be nearly 

 flat (proserpina), or with an obliquely conical center (flavofas- 

 ciata. juanita). Head and skin smooth. Spiracles single- 

 colored, yellow in flavofasciata and proserpina, black in gaurce. 

 Head squarish, higher than wide in proserpina, full as wide as 

 high in flavofasciata. Adfrontals only about \ as wide as 

 front is high, with their setae i below the top of the front. Front 

 nearly half as high as head, broadly triangular. Ocelli normal.
