LIFE-HISTORY AND HABITS. 
The life-cycle is as yet imperfectly known, but so far as can now be 
judged is as follows: When the insects first appear the eggs are depos- 
ited in the squares and bolls, and the larva? hatch and feed on the 
interior substance of the buds and bolls. The larva; sometimes feed 
on the interior of the seed, leaving only the shell, but usually eat seed 
or fiber indifferently. The larva gradually reaches full growth, having 
by this time formed a cell of sufficient size to accommodate itself, and 
in this it pupates. The cell is usually formed next the outer wall or 
pericarp of the boll, so that the weevil, when transformed, has only to 
make its way through this wall to escape. In issuing, it thus leaves a 
small hole in the pericarp, which marks the cell in the infested lock of 
the boll. As many as eleven larva; have been found in one boll. 
Judging from the habits of the allied species. Anthonomus signatus, 
and allowing for differences in size and climatic conditions, the dura- 
tion of the life-cycle is probably about thirty days. 
In the newly infested region in Texas, the weevils were first noticed 
in the cotton fields from about the middle of August to the last of 
September: in the newly infested region of Coahuila, a month earlier; 
in the older infested regions of Texas (Brownsville) and Coahuila 
(Hermanasj, as early as May to June. Approximate dates of their 
first appearance in newly infested regions have been received as 
follows: Corpus Christi (Xueces region), middle of August; Beeville, 
last of August and first of September; San Diego, first of September. 
Nothing is known positively concerning the number of annual 
broods, but I think there is no doubt that there were two broods in the 
newly infested region, and in the older districts, where the weevils 
appear in May and June, there must be four or more broods annually. 
At San Juan Allende, Coahuila, two very small larvae were found in 
buds, November 23, and at Alice, Tex., another was found in a green 
bud. December 12. This seems to indicate a very late brood if, indeed, 
the broods are at all regular. I am inclined to think that, egg-laying 
goes on at all times, so that the broods are more or less irregular. 
Food plant* and habits of feeding of the adult. — The only food plant 
so far as known is cotton. The adults seem to feed both on the buds and 
boll::, and throughout the season as long as the weather is warm. By 
means of the small jaws at the end of its beak, the weevil eats through 
theskinof the bud or boll, making a small hole therein. Specimens were 
found as late as December 10,36 miles north of Brownsville, with their 
beaks sunk to full length in half-grown green bolls, apparently feeding 
on the juices within. 
Extended inquiry, confirmed by my own observations, shows that the 
weevils always remain within the squares or on the bolls, and never 
feed on the leaves, nor are they ever seen on the latter. 
The weevils were found at SanTomas, and just north of Brownsville, 
infesting fields of sea-island cotton as badly as the upland variety.
