THE CACTUS-FEEDING PHYCITINAE — HEINRICH 343 



consequently appear somewhat more ashy gray than the Colorado 

 specimens ; but this pale suffusion also shows in Kansas specimens and 

 in a number of those from Utah. 



Dodd has also treated doddalis and dentata as separate species. 

 He writes : "In our concept, M. doddalis is distinct from M. dentata. 

 We would give the distribution of dentata from the Panhandle of 

 Texas across to northern Arizona, north through Colorado, Utah, 

 and Kansas to Idaho and "Wyoming. M. doddalis occurs through 

 western Texas and New Mexico to southern Arizona." 



Possibly there may be local races involved, but if so their distribu- 

 tion does not correspond with any consistent differences in color or 

 habitus, for, as stated, the Kansas specimens that fall within the 

 supposed dentata area are more like typical doddalis than they are 

 like Colorado dentata. 



I think that the two names apply to nothing more than local vari- 

 ants of one rather variable species. 



Descriptions of the o^gg., larva, and pupa are given in the paper by 

 Kellogg. 



As pointed out by Barnes and McDunnough, the female paratypes 

 of junctolineella (from Colorado) are not conspecific with the male 

 type (from Texas) but must be referred here. One of these para- 

 types is now in the National collection. 



2. Genus OLYCELLA Dyar 



Olycella Dyab, Proc. Eut. Soc. Washington, vol. 30, p. 134, 1928. (Genotype: 

 Melitara junctolineeUa Hulst.) 



Antemia of male bipectinate, of female shortly bipectinate. Labial 

 palpus obliquely ascending (sometimes in the female the third seg- 

 ment is bent forward, which gives the palpus a porrect appearance, 

 but the second segment is always deflected upward and reaches nearly 

 as high as the top of the head). Maxillary palpus squamous. Hind 

 wing with veins 7 and 8 approximate beyond the cell ; 3 and 5 con- 

 nate. Eighth abdominal segment of male simple. 



Male genitalia with apical process of gnathos bifid; harpe with 

 apex evenly rounded; vinculum short; anellus with base of plate 

 narrowly sclerotized, arms moderately long and stout ; aedeagus stout, 

 moderately long. 



Female genitalia with signum, the latter a small ridged plate ; bursa 

 copulatrix wrinkled, otherwise simple and without scobinations ; 

 ductus bursae with a pair of sclerotized plates on inner wall at genital 

 opening; ductus seminalis from center of bursa. 



Larva white with broad blackish or purplish cross bands on the 

 caudal margins of the segments; sclerotized plates surrounding setae 

 rather small ; three setae in group VII on abdominal segments T and 8.
