BAGWORM MOTHS OF THE WESTERN HEMISPHERE 117 



Wings similar to 0. t. townsendi in shape and general pattern, but 

 with more fuscous scaling, distinctly darker. Primaries with discal cell 

 completely filled with dark, fuscous scales, usually broadly oblanceolate 

 (fig. 355), flat to slightly carinate, with bluntly rounded to slightly 

 dentate apices; dark apical area beyond cell gradually becoming lighter 

 toward wing margin; remainder of wing yellowish brown as in 0. t. 

 tovMsendi; costa relatively straight; apex acute; termen and venation 

 similar to other subspecies; Mo and 3 in both wings usually stalked or 

 connate, rarely separate. Secondaries with cell Ki invariably stalked; 

 termen slightly excavate to nearly straight. Wing expanse 36-45 mm. 



Male genitalia. — -Very similar to 0. t. tovmsendi. 



Female. — Not examined. 



Case. — (Fig. 103.) Length 70-90 mm.; diameter approximately 

 15 mm. Very similar to typical subspecies in size and construction; 

 bag heavily covered with sections of twigs, 20-30 mm. long usually, 

 loosely applied longitudinally; posterior 15-20 mm. of male case bare. 



Type. — In the Zoologisches Museum der Humboldt-Universitat 

 {0. mexicanus) ; American Museum of Natural History {0. multidentatus) . 



Type locality. — Mexico {0. mexicanus) ; Misantla, Mexico {0. 

 midtidentatus) . 



Recorded hosts. — "Pinaceae: Araucaria sp., Pinus leiophylla 

 Schlecht. & Cham., Pinus oocarpa Schiede, Pinus teocote Cham. & 

 Schlecht.; Taxodiaceae: Taxodium mucronatum Tenore; Anacardi- 

 aceae: Schinus molle L.; Asteraceae: Baccharis conferfa H. B. & K., 

 Mordanoa tormentosa Cerv., Stevia sp. ; Fabaceae: Acacia sp., Prosopis 

 juliflora (Swartz) DC; Fagaceae: Quercus sp.; Oleaceae: Ligustrum 

 japonicum Buch.-Ham.; Rosaceae: Rosasp." (Vazc^uez, 1942). 



Distribution. — (Map 10.) Recorded from the Volcanic Section 

 and Atlantic Plain of central Mexico, from Guadalajara east to 

 Misantla, Veracruz. 



Discussion. — Fortunately, I was able to examine Gaede's type 

 specimen of 0. mexicanus and I am convinced that it is identical with 

 the other members of this taxon. Previous workers (e.g., Vazquez, 

 1942, 1953), misled by the brief and inadequate original description, 

 erroneously had applied this name to the light color phase of 

 0. kirbyi, from which the type of 0. mexicanus clearly differs. 



The wing outline of this subspecies is quite similar to that of O.t. 

 townsendi: the front costa is straight and the hindwings are relatively 

 broad and rounded. The termen of the primaries, likewise, is not as 

 strongly oblique as observed in most specimens of 0. kirbyi. The 

 wing pattern is also similar to that of the typical subspecies, but it 

 differs primarily in its darker shade, especially of the entire cell. 



In Mexico some variants of 0. kirbyi approach 0. t. mexicanus in 

 appearance, and a few specimens in poor condition can be determined
