OCCURRENCE OF SPECIES. 29 
The range of the Microdontomerus is evidently western. ‘T'wenty- 
three per cent were secondary parasites. 
2. Eurytoma tylodermatis Ashm. This species, while not veryimpor- 
tant in any part of the State, is very well distributed. It was recorded 
continuously after July 12, 1906. Specimens were bred from mate- 
rial collected at Beeville, Brownsville, Calvert, Cuero, Dallas, Goliad, 
Hallettsville, Overton, Palestine, Trinity, Victoria, and Waco, Tex., 
and at Mansfield and Many, La. No records were obtained from 
Corpus Christi, Corsicana, Junction, Kerrville, Lula, Marshall, Mine- 
ola, and Taylor, Tex.; nor from Orange, La. Specimens were sent in 
by Prof. A. L. Herrera from Allende, Coahuila, Mexico, with the note 
that it was abundant at that place. 
3. Bruchophagus herrere Ashm. This parasite has not been taken 
in the United States. It was described from Coahuila, Mexico. 
4. Cerambycobius cyaniceps Ashm. This parasite has been taken 
- at all points investigated except those in the Edwards Plateau region. 
5. Catolaccus incertus Ashm. This parasite has not been taken at 
Overton or Marshall in northeastern Texas, but is common at all other 
points investigated. 
6. Sigalphus curculionis Fitch has not been recorded since the first 
specimen was bred at Calvert, Tex. 
7. Urosigalphus anthonomi Cwfd.t One female was bred from a 
cocoon in a weevil cell from material collected September 5 at Browns- 
ville, Tex. As the former record wasalso from Brownsville, this species 
may be taken to be Mexican in origin. 
8. Urosigalphus schwarz. Cwfd.t From 300 squares Mr. E. A. 
Schwarz and Mr. H.S. Barber bred 5 females and 1 male of this newly 
described species at Cacao, Finca Trece Aguas, Alta Vera Paz, Guate- 
mala, during April, 1906. 
9. Bracon mellitor Say was bred from all points, except Overton and 
Marshall in northeastern Texas. The form known as bracon xan- 
thostigma has only been bred from the weevil between September 16 
and April 28 in the various years of this investigation. A specimen 
of this species is recorded on the Bureau of Entomology files (D. A. 
6424 (412)) as bred from the boll weevil at Coahuila, Mexico, Novem- 
ber 15, 1902, by Professor Herrera. Specimens were sent in by Pro- 
fessor Herrera from Allende, Coahuila, Mexico, during 1906, with the 
notes that they were quite common. - 
10. Bracon dorsator Say was not bred until October in 1906. It is 
only known to occur between August 2 and December 17 in Texas. 
It is probably another instance of seasonal dimorphism and identical 
with Bracon mellitor. 
11. Braconid. One female of this species was bred September 1 
from a cocoon in material collected on the ground at Victoria, Tex. 
The specimen was lost in transit.
