VARIETIES. 
Two varieties and a subvariet}^ of the bollworm moth have been des- 
ignated from the United States; one varietv from Hawaii, one from 
Europe, and one from Australia, with two subvarieties. With the 
forms occurring in the United States, at least, there is almost every 
intergradation in color and markings, and it is doubtful if these ma}^ be 
referred to in a more definite waj^ than as the more abundant types. 
In a collection of 65 moths, bred during the present investigation from 
larvae taken on corn, cotton, and other phmts in Texas, 35 may be 
classed as variet}^ ochracea^ with some of them approaching y?^^<:?«, and 
30 as variet}^ innhrosa. The forms which have thus far been indi- 
cated are given in the table below^ with their essential points of dif- 
ference, as taken from the British ]\Iuseum Catalogue (1. c), and 
Tutt's British Nocture and Their Varieties.* 
Heliothis obsoleta Fab. 
Table of varieties and subvarieties. 
(1) orhracea Ckll. Ordinary tawny colored form figured in Fourth Rept. U. S. Ent. 
Comm., 1885, pi. 3, fig. 7. 
(2) fusca Ckll. Dark brown (European). 
(3) umbrosa Grote. Usually rather large, paler, and more olivaceous than the Euro- 
pean type (Southern United States esjjecially ) , the larva, the common boll- 
worm. 
(a) sub-var. eumacnlata Ckll. Stigmata margined with ferruginous (Colorado). 
(4) haicaiiensis, n. var. Fore-wing with prominent angled dark brown median band , 
diffused on outer side ( Hawaii ) . 
(5) rubescens, hind- wings with the groimd color orange yellow (Australia). 
(«) Head, thorax, and fore-wing suffused with rufous. 
(6) Head, thorax, and fore-wing suffused with dark pink. 
COMMON NAMES. 
Owing to the fact that the boUworm attacks a great variety of plants, 
and to the further fact that it occurs in most parts of the civilized s\'orld, 
it has become known under numerous common names. 
In the United States it is very generally known under the name of 
bollworm'or corn-ear worm. In the States of the cotton belt the 
former name is ver}^ generalh^ used in referring to this specie^, or it is 
"A bombyx, with wings deflexed and j^ellowish; with a middle spot and posterior 
obsolete streak, rather obscure. Habitat, islands of South America [W^st Indies?]. 
Collector, Father Smith. Of medium size. The antennas simple. The body yellow- 
ish, with wings yellowish, with a more obscure middle spot. Posteriorly with an 
obsolete streak which is spotted with very small j)unctures. Hind ma'gins brownish. 
Hind wings yellowish, with posterior margin fuscous [smoky?].— e. a. s.
