GASTROPACHA (EPICNAPTERA). 185 



2. Termen not dentate ; hindwings with one or two pseudoneuria — ilicifolia 

 (— Gastropacha) . 



This tribe is the restricted Gastropacha of Germar (Bomb. Spec, 

 sect. 2, p. 50), and is practically the coitus Phyllodesmae 'of Hiibner 

 (Verz., p. 190), details of which may be obtained by reference to 

 vol. ii., pp. 450 — 451. Meyrick notes it as a small European and 

 Asiatic group. There would appear also to be a very fair extension 

 of Gastropacha into North America, if Kirby's references to this genus 

 are accurate. Kirby gives {Cat., p. 824): G. americana, Harr. (N. 

 America), ferruginea, Pack. (Michigan), calif omica, Pack., and roseata, 

 Stretch (California), alascensis, Stretch. He also doubtfully adds two 

 Panama species — modesta, Druce, and thyatira, Druce. Huguenin 

 records {Mitt. Schw. Ges., iv., p. 30) a case of supposed hybridity 

 between" Eutricha quercifolia and Gastropacha betulifolia (tremu/ifolia).

The genus Gastropacha is diagnosed {Die Schmett., iii., p. 259) 

 by Ochsenheimer as follows : 



This genus falls into several families, each of which has, indeed, its distinguishing 

 characters, but which cannot well be separated, since the most unmistakable 

 transitions from one to another occur. Excepting the superior thickness of the 

 abdomen in the ? , no general distinctive character is to be found, unless one goes 

 upon larval conditions ; therefore I took the generic name from the Greek 

 yaar^ozzzx enter, and 7r«£oe=crassitudo.
