40 PARASITES OF THE COTTON BOLL WEEVIL. 
No dark forms of this species were bred until September 10, 1906, 
except a single 6. dorsator which was bred from Cuero material col- 
lected August 31. The rest were all bred from material collected 
at Brownsville, September 29; Dallas, October 2, 6, 10; and Waco, 
October 12. The record of all Bracon bred after October 10 is as 
follows: 
October 10, Bracon mellitor, 3 males, 5 females. 
ae Do. 1 male. 
12: Do. 1 male. 
113}, Do. 1 female; mellitor xanthostigma, 2 females. 
15, Do. 1 female. 
18, Bracon mellitor xanthostigma, 3 females. 
20, Do. 2 females. 
22, Bracon mellitor, 3 females; mellitor xanthostigma, 2 females; mel- 
litor dorsator, 2 males, 1 female. 
24, Bracon m. xanthostigma, 1 female. 
Die Do. 2 females; m. dorsator, 1 female. 
ol, Do. 2 females. 
November 1, Do. 3 females; m. dorsator, 1 male. 
5, Do. 1 female. 
6, Bracon mellitor dorsator, 1 female. 
14, Bracon mellitor canthostigma, 1 female. 
11. An undetermined braconid of the size of Bracon mellitor, but 
with the base of the abdomen black and belonging to a different sub- 
family, was bred September 17 from a yellow cocoon in a fallen 
square collected at Victoria, Tex., sabe 1. Unfortunately this 
was lost in the mails. 
12. Myvophasia aznea Wied. ‘This species is recorded as a parasite 
of Balaninus nasicus Say, Chalcodermus sp., Conotrachelus juglandis 
Lec., and Sphenophorus parvulus Gyll. (Coquillett, 1897), and also of 
Ampeloglypter sesostris Lec. (Aldrich, 1905). One specimen was bred 
July 6 by the writer from a larva of Conotrachelus affinis Boh. found 
in a hickory nut collected June 8 at Logansport, La. As parasites 
of the boll weevil from fallen squares collected at Many, La., August 
23, 1 male was bred September 5 and 1 female September 8, while 
1 failed to mature. From a hanging square collected at Waco, 
Tex., August 29, a puparium was obtained but the fly not bred. 
From a small boll collected at Victoria, Tex., July 12, a deformed 
fly was bred. 
Parasitism by this species can always be positively proved if the 
puparium is found, as it is inside of the stretched skin of the weevil 
larva. The affected larva is of a tawny parchment color and shows 
the projections of the appendages of the fly puparium. 
The developmental period is undoubtedly in excess of 28 days, as 
shown by the first record above. 
13. Several attempts have been made to introduce Pediculoides 
ventricosus Newp. into Texas as a parasite of the boll weevil, but.
