46 PARASITES OF THE COTTON BOLL WEEVIL. 
8. Anthonomus nigrinus Say is an eastern weevil which breeds in 
the buds of Solanum carolinense and various other solanaceous plants, 
occurring principally in the spring and early summer, but not con- 
fined to one generation. It oviposits in the buds, causing them to 
fall. The larva makes its cell in the center of the bud through the 
pistil and all of the stamens and pupates in this cell. It is a host of 
Catolaccus incertus. 
9. Anthonomus albopilosus Dietz is a fall species which breeds in 
the seed of Croton capitatus and C. engelmanmi, weeds which are very 
abundant in pastures. The larve eat out one seed and then enter a 
second and form their pupal cell in this. The weevil serves as a host 
to Cerambycobius cyaniceps, Catolaccus incertus, and Bracon mellitor. 
10. Anthonomus xneolus Dietz is a spring species which breeds in 
the buds of Solanum torreyi, S. rostratum, and S. eleagnifolium. The 
larvee feed within one or two anthers, in the latter case forming a cell 
which cements the two together. In many cases the flower does not 
fall, and is able to fruit. The weevil is a host of Catolaccus incertus. 
11. Anthonomus eugeni Cano (xneotinctus Champ.), the pepper 
weevil, is a recent introduction from Mexico. It is a fall species, 
which breeds in the interior of the cultivated peppers. (See Plate III; 
A, C.) Itisa host to Catolaccus incertus, Bracon mellitor, and Pedi- 
culoides ventricosus, as determined by Professor Herrera. Anthonomus 
mexicanus Boh., another pepper weevil, is very likely identical. 
12. Anthonomus squamosus Lec. breeds in the heads of (rindelia 
squarrosa, a fall plains plant, which is very abundant in semiarid 
Texas. The weevil larva makes a cell among the seed, which is 
formed of the hardened. gum of the flower and excreta. It has 
probably only one generation. It is very highly parasitized and 
principally by Bracon mellitor and Hurytoma tylodermatis. 
13. Anthonomus disjunctus Lec. breeds in the heads of Heterotheca 
subaxillaris, a fall plant, which is very abundant along roads, waste 
places, and on meadows. The weevil larva makes a small cell, formed 
of the hardened gum and excreta of the weevil, among the seed. 
There is but one generation. Hurytoma tylodermatis and Catolaccus 
incertus have both been bred from this weevil. 
CRYPTORHYNCHINI. 
14. Conotrachelus affinis Boh., the hickory nut weevil, has been 
found to be the host of Myiophasia xnea. It is an early. summer 
weevil. Pupation is in the ground. 
15. Conotrachelus nenuphar Herbst, the plum and peach curculio, 
breeds in the fleshy part of the fruit and pupates in the ground. It 
is the host of Sigalphus curculionis, which has once been bred from 
Anthonomus grandis.
