February, ’24] jones and bradley: tabanidae of Louisiana 47 
Chrysops obsoletus Wd. A larva and a pupa of this species were 
found in mud beside a shallow, slowly-flowing brook in a small clearing in 
woods at Magnolia bn May 8, 1923. The ground along the edge of this 
brook was swampy and covered with an abundant growth of water- 
plants. The larva pupated in confinement without having received 
food and a female adult issued on May 28. The pupa produced a male 
adult on May 15. 
Chrysops pikei Whit. A single larva of this species was taken at 
Magnolia on January 4, 1923, in mud at the edge of a pool of stagnant 
water in a depression in a wooded area. The character of the flora in 
and around the pool indicated that water was present in the depression 
throughout the year. The pupa was found on March 13 and on April 2 
a male adult issued. 
Tabanus americanus Forst. Three larvae were taken from mud at 
the edge of a shallow pool of stagnant water in East Baton Rouge 
Parish on January 10, 1923. In this pool, and on a limited area around 
its edge, there was a heavy growth of hardwood trees and some cypress, 
with a dense undergrowth of rushes and switch cane. Other smaller 
aquatic plants were present, indicating that the pool was more or less, 
permanent. The area was entirely surrounded by cultivated land, 
although the outer edge of an extensive swamp was only about 200 
yards distant in one direction. 
The pupa of one of these larvae was found on May 29 and a male 
adult issued on June 2. Another pupa was found on June 12 and on 
June 16 a male adult issued. The third pupa was found on August 6 
and the adult, also a male, issued on August 16. 
Tabanus benedictus Whit. Two small larvae were taken on Decem¬ 
ber 29, 1922, in East Baton Rouge Parish from mud along the edge of 
shallow, stagnant water in a slough about 100 yards long and about 12 
feet in greatest width. There was not much vegetation growing on the 
margin of the slough, or in it, possibly due to the frequent flooding to 
which the locality is subjected. The pupae of the two larvae were 
found on June 18. One adult female issued on June 27 and another on 
July 1. * 
Tabanus cymatophorus O. S. One larva was taken from mud at the 
edge of a small, shallow, stagnant pool in woods at Magnolia on July 
12, 1923. The pupa was found on August 14 and a male adult issued on 
August 19. 
Tabanus lineola Fab. Of 24 larvae of this species, reared to the 
adult stage in confinement, 22 were found in mud around pools of stag-
