THE LARGER CANNA LEAF-ROLLER. 



diameter is l."25 nun. ; height about 0.7 mm. Eggs have not been seen 

 by the writer, and the color does not appear to have been designated. 



The laroa^ or caterpiDar, is quite remarkable because of its semi- 

 transparency. Its surface is Avithout hair, and the general color is 

 moderatel}' j^ale green, with dark-orange subtriangular head, •which 

 is marked by a frontal subtriangular space. The thoracic segments 

 are greenish testa- 

 ceous and more or 

 less tinged Avith 

 orange, at least 

 in preserved spec- 

 imens. The re- 

 mainder of the 

 body is nearly 

 transj^arent, pre- 

 senting a view of 

 the vascular and 

 nerv^ous system be- 

 neath the skin, as 

 illustrated in fig- 

 ures 1 and 6, h. 

 The length of the 

 larva, when full 

 grown, is about \\ 

 inches, but when 

 fully extended it 

 reaches 2| inches. 



The inipa is 

 nearly as striking 

 as is the larva. It 

 is of similar pale 

 greenish color and 

 of the appearance 

 shown in figure 6, 

 <r, d. Tlie head is 

 prolonged into a 

 curv^ed process, and 

 the tongue extends 

 in a nearh' straight 

 line considerably 

 beyond the prolonged anal tubercle. AVithout the projection^ it is 

 nearly as long as the unextended larva. 



DISTHIIU'TION. 



Scudder states that the principal range of this species is from Cen- 

 tral America to the northern ])ai(s of the South American Continent,
