140 ENTOMOLOGICAL NEWS. [April, 



Of the remaining species referred to Lithosia in Prof Smith's 

 list, L. b icolor Groie, may remain in the genus; the others are 

 synonyms. 



Family ARCTIID^. 



Crocota intermedia Graef. 

 Var. parvula n. var. 



Differs from the typical form in the width of the black border 

 of hind wings. In inierynedia the border covers two-thirds of 

 the wings; here, one-third or less. 



Type, one 9 , in Mr. Neumoegen collection, caught by Mr. 

 Bruce in western Colorado. 



Mr. E. L. Graef has a similar specimen from Arizona. 



Arachnis picta Pack. 

 Var. citra n. var. 



The ground color of head, thorax, anal tuft of abdomen and 

 primaries varies from light orange to lemon between the normal 

 gray maculations. Fringes of both wings yellow. Abdomen, 

 as well as secondaries, deep red with a purplish sheen. 



It differs from the typical Californian insect by having the sec- 

 ondaries more distinctly subhyaline, especially in the males. 

 Below, primaries lemon to light orange, especially so in basal 

 space and along costa; along costa of secondaries an area of 

 lemon, and the veins of males scaled with the same color. Ab- 

 domen light yellow. The most remarkable feature about this 

 variation is that it is of a much larger size than the typical form. 

 Expanse of wings: %, 50 — 51 mm.; $, 62 — 65 mm. Length 

 of body: % , 12 mm.; $, 15 — 20 mm. 



Types, males and females, in Mr. Neumoegen's collection. 



Hab. — Western Colorado. 



Mr. Bruce, who caught these charming insects and who sug- 

 gested the varietal name, writes us as follows: "This form is 

 found nearly on the western border of Colorado at low elevation 

 (6000 feet), and is very constant in color. I have them even a 

 little pinker and not quite so yellow. The ordinary form is not 

 found at that place at all, yet it is common 120 miles east of there, 

 and I have reared a good many from females taken in the Ar- 

 kansas Valley, all being the ordinary form. It is so local and 

 constant in color, it is surely worthy of a name."
