92 HENRY L. VIERECK. 



westcottii, Albuquerque, New Mexico. 

 erebus, Mesilla Park, New Mexico. 

 hamata, La Cueva, Organ Mts., New Mexico. 

 trita, Las Graces, New Mexico. 



Two co-types and seven homotypes of danaus in Coll. Am. Ent. 

 Soc. are Photopsis and not Odontophotopsis. 



Type and metatype of bellerophon have no crenulate ridge on 

 mesosternum, which is simple; therefore they belong to Photopsis. 



0. trunculus n. sp. may be the same as simplieiventris Mel. 



0. mellicaixsa Blake has a fringe of plumose hairs on edge of 

 second and third segments, some plumose hairs on disc of third seg- 

 ment, beyond the hairs are simple. To this extent the types disa- 

 grees with Mr. Melander's interpretation. 



The contiguous punctures of mesonotum and the pit on the front 

 instead of an impressed line will readily separate 0. sevens n. sp. 

 from westcottii, to which it is closely related. In serous the first five 

 segments have an apical fringe of plumose hairs, beyond this point 

 the hairs are simple. 



0. avellanus appears to be nearest erebus Mel., and like that spe 

 cies has an apical fringe of plumose hairs on all abdominal segments. 



0. delodontus is related to erebus, and has plumose fringes on all 

 segments. It is separated at once by the size and the well-separated 

 punctures on the mesonotum.
