closely welded together and forming a conical tip. at the extremity of 
which are two very minute brown tubercles" (Riley). The length is 
11 to 12 mm , or a little less than half an inch. 
The cocoon. — Transformation to pupa takes place in a cocoon formed 
of earth and constructed near the surface. The appearance of a cocoon 
is well illustrated at e of figure 12. The measurement is a little less 
than five-eighths of an inch in length, and three-eighths of an inch in 
diameter. The outer grains of sand are rather loosely held together, 
but the interior is fairly substantial, the lining being of light-gray 
color, nearly white. 
DISTRIBUTION. 
So far as the writer is aware, no comprehensive list of localities of 
this species, or other data that give any idea of the insect's distribu- 
tion, have ever been published. From material received at this office 
and at the National Museum, and from reports of correspondents, the 
following list of localities has been compiled: 
Newark and Dover, Del.; Cabin John, Marshall Hall, and elsewhere in Maryland; 
Cameron's Mills, Carterton, Chesterbrook, St. Elmo, and Alexandria, Ya. ; Brookland 
and elsewhere in the District of Columbia; Lexington, Ivy.; Springfield, Ohio; 
Aurora and Lafayette, Ind. ; Mount Juliet, Tenn. ; Carbondale and Anna, 111. ; Raleigh, 
N. C; Montreal, Athens, Macon, and Storeville, Ga. ; Alabama; Lone Star, Oxford, 
and Agricultural College, Miss. ; West Point, Nebr. 
From the above list it would seem that the southern distribution of 
this species and its southern origin are well established. The moth 
has been recorded as occurring farther west and north, but injurious 
occurrences are lacking, at least in reports of injuries sent to this 
office. It seems, therefore, that the species attains its highest devel- 
opment in the Lower Austral life zone, although occasionally it 
invades the Upper Austral and even, perhaps, the Transition area. 
This, however, is only temporary. 
RECENT INJURY. 
During 1899 we received this species from Mr. E. Dwight Sander- 
son, at that time at Raleigh, N. C, September IS. They were found 
in numbers on cabbage. Jury 28, Mr. S. S. Simms, Storeville, For- 
syth Count} 7 , Ga., sent this species, also found on cabbage. Septem- 
ber 18, Mr. Thos. I. Todd, Athens, Ga., sent the species, with the 
accompanying information that it did great damage that year feeding 
in the buds and tender leaves of cabbage and turnip, and stated also 
that it was known as "the common webworm," in contradistinction to 
the imported cabbage webworm (Hellula undalis). He stated that 
this species succumbed to Paris green and pyrethrum dusted upon the 
plants, where the imported species did not. 
In 1900, Mr. J. H. Heard, Montreal, Ga., sent this cabbage worm, 
July 5. with information that it was concerned in attack on cabbao-e
