BAGWORM MOTHS OF THE WESTERN HEMISPHERE HI 



and Veracruz in the Sierra del Sur Section and Atlantic Plain, re- 

 spectively, of southern Mexico. 



Discussion. — Vazquez's published photograph of the type of 0. 

 w.ortonjonesi appears to be nothing more than a rather heavily scaled 

 example of 0. toumeyi. In the collection of the United States Na- 

 tional Museum there are specimens of 0. toumeyi from Tucson, 

 Arizona, in which the wings are intermediate in scaling between 

 Vazquez's type and the typical, nearly scaleless form of 0. toumeyi. 

 In the same collection from Misantla, Mexico, two specimens agree 

 very closely -svith typical 0. toumeyi. Further, the larval cases of 

 0. mortonjotiesi and 0. toumeyi are indistinguishable. For these 

 reasons, it is believed that these two names represent the same 

 species.

Oiketicus assimilis Vazquez, Anales Instit. Biol., vol. 13, no. 1, p. 268, figs. 32-35, 

 45, 1942; in Mem. Congr. Cient. Mex., Vll-Cienc. Biol., pp. 324, 339, 1953. 



Male. — (Fig. 48.) Antennae approximately 35-segmented with 

 apical % strongly biserrate. Vesture of body dark brown. Epiphysis 

 about K length of foretibia. 



Wings slender, semitransparent, with a sparse scattering of dark 

 fuscous scales. Discal scales of forewing linear oblanceolate, bluntly 

 rounded to truncate tips; outer margin of primaries as in 0. toumeyi, 

 that of hindwing decidedly more excavate, range of variation not 

 known. Wing expanse 35 mm. 



Male genitalia. — As described for genus. 



Female. — Unknown. 



Case. — (Fig. 100.) Length 60 mm.; greatest diameter 15-20 mm. 

 Heavily ornamented with circular thatching of short twigs and very 

 small leaf fragments, imparting extremely irregular, spindle-shaped 

 outline to case, partially covered by very thin, incomplete sheet of 

 greyish white silk. 



Type. — In the Instituto de Biologia, Mexico City. 



Type locality. — Not definitely stated; either Patzcuaro, 

 Michoacan, or Tepoztlan, Morelos, Mexico.
