Celatoria diabroticae Shinier. A large series of specimens 

 taken from flowers and sweeping grass. Abundant throughout the 

 spring and summer. The specimens vary in size from 4 to 6 mm. 

 The characters which serve to separate this species from Tachinophyto 

 florid cnsis are obscure and the species may easily be confused. 

 Coquillett's description appeared under the name of Celatoria crawii, 

 Insect Life, Vol. 2, February, 1890, p. 235, and later it was placed in 

 synonymy with Celatoria diabroticae. A few characters which serve 

 to separate it from Tachinophyto floridensis may be mentioned here. 



Eyes bare, face much receding below ; antennae nearly as long as 

 face, arista thickened on basal half. Scutellum with three pairs of 

 marginal macrochaetae and a short discal pair, apical cell terminating 

 nearly at extreme wing tip and closed in the margin, third vein with 

 one strong 1)ristle at base. This species is a parasite of Diabrotica 

 vittata and 12-punctata. Reported from College Station. Texas, by 

 Coq-iillett, Revis. Tachin. N. A. 1897, p. 59. 



Exorista pyste Walker. Common throughout the summer. Char- 

 acterized by a high-pitched note in flight, not unlike Winthcmia 

 quadripustulata, which species it resembles in nature. Collected from 

 various flowers and particularly from foliage near the ground. Also 

 collected in Knox County, Texas. A parasite of Lepidoptera. Speci- 

 mens vary greatly in size, ranging from 4 to 8 mm. in length'. Pre- 

 viously reported from Tiger Mills, Texas, by Coquillett, Revis. Tachin. 

 N. A. 1897, p. 93- 



Frontina archippivora Williston. Not common, one male speci- 

 men taken in the insectary. May 4, 1918. Eight additional specimens 

 collected from flowers of broom weed, Amphiachyris dracunculoides 

 Nutt., in October, 1917. A moderately large species, the specimens 

 are nearly uniform in size. Reported as a parasite of several species 

 of caterpillars. Also collected in Knox County, Texas. Listed from 

 Texas by Coquillett, Revis. Tachin. N. A. 1897, p. 106. 



Gonia capitata DeGeer. In this locality this species is uniformly 

 light yellow and more robust than the dark form of the north. Not 

 abundant, most common in late summer and fall. Collected from a 

 large number of wild flowers, most frequently on broom weed, Amphi- 

 achyris dracunculoides Nutt. Also collected in Wilbarger County, 

 Texas, in May, 1919. A series of 34 specimens taken ; all robust, 

 nearly uniform in size, but with large variations in color markings. 

 Collecting dates range from May 3 to November 11. Reported from 

 Texas l)y Coquillett. Revis. Tachin. N. A. 1897, p. 133- 



Heteropterina nasoni Coquillett. Not abundant, but persistently 

 present throughout May, June and July. It has been reported as bred 

 from a grasshopper, by W. R. Walton, Proc. U. S. N. M., 1914, Vol.
