PSYCHE. 



[October 1895. 



its relative development on the piozona 

 and metazona, and also the overlapping 

 of the lobes. The anal, and sometimes 

 also the posterior half of the discoidal, 

 area of the tegmina is occasionally of 

 a marked rosaceous tint. Eight speci- 

 mens from the Gulf coast of Texas are 

 noticeably larger and more bulky and 

 have the postei'ior process of the pro- 

 notum more produced than those from 

 Dallas. 



Prof. Bruner has sent me a specimen 

 from Tiger Mills, Texas, and reports it 

 also from San Antonio, and S. VV. 

 Texas, and Barbour Co., Kansas. The 

 National museum material consists of 

 three examples from Dallas, and a pair 

 from Carrizo Springs, Texas, the latter 

 taken Aug. 28 by Dr. A. Wadgyniar. 

 Scudder's collection contains about forty 

 specimens chiefly from Dallas, taken by 

 Boll, a number collected by Belfrage, a 

 single example from Dingo Bluffs, 

 N. C, Nov. 15, and one from Talla- 

 hassee, Fla., Glover. These latter are 

 the only examples known from the 

 eastern States.

Examination of a considerable num- 

 ber of specimens indicates that the forms 



described as collare., zvyomingianum 

 ( = oculaium) , and scudderi approach 

 each other so closely that it is at the 

 present writing impossible to definitely 

 limit them. Although typical spec- 

 imens of these forms may be readily 

 distinguished, others cannot be referred 

 to any one of them with certainty : for 

 this reason it seems best to regard them 

 as races of one composite species. Yet 

 it is not improbable that with more sys- 

 tematic collecting and observation in 

 the territory where the tbrms overlap a 

 limitation may be found possible. To 

 this group belongs also the Oed. iita- 

 hensis of Thomas and other western 

 forms described here.

This race, the typical collare of 

 Scudder, is a widespread and common 

 form in the central part of the country, 

 and varies much in color and size. 

 Only about one-third of the specimens 

 seen are of the •' collared" ty^se of col- 

 oration. The hind femora sometimes 

 have the proximal two fuscous bands 

 slightly connected internally, but never 

 to such an extent or depth of tint as in 

 scudderi. Individuals vary much in 

 wing-length, and in size, as the follow- 

 ing measurements show : —
