smallest 5 mm. in length. Collected in Knox County, Texas. Listed 

 from Texas by Coqiiillett, Revis. Tachin. N. A. 1897, p. 102. 



Plagia americana v. d. Wulp. A medium-sized, shiny black 

 species. Most common in early spring. Collected frequently in low 

 damp places from foliage near the ground. Rarely taken in midsum- 

 mer. Quite uniform in size, varying from 6 to 9 mm. in length. 

 Collected also in Knox County, Texas. 



Plagiprospherysa parvipalpis v. d. Wulp, Common in the spring 

 and summer. 17 specimens taken in the insectary in June and July. 

 Collected from aphid-infested cotton and cucumber foliage. Speci- 

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



Senotainia rubriventris Macquart. Not very abundant but present 

 throughout the year. Collecting dates range from March to Novem- 

 ber. Frequently collected from bare ground. Probably a parasite of 

 some soil-burrowing host. Prof. Herbert Osborn observed this spe- 

 cies entering the burrow of a pompilid wasp (Ohio Naturalist, Vol. 7, 

 p. 38). The specimens vary from 4.5 to 8.5 mm. in length. 



Senotainia trilineata v. d. Wulp. Abundant from April to Octo- 

 ber. Like the above species, it is most commonly collected from the 

 ground and it probably parasitizes some similar soil-burrowing host. 

 Dr. Aldrich, Ann. Ent. Soc. Amer., Vol. 8, March, 1915, p. 82, states, 

 "Presumably they parasitize these (burrowing) Hymenoptera as their 

 European congeners do, but none have been bred in this country." 

 A large series of specimens taken, varying from 3 to 6 mm. in length. 

 Listed from Texas by Coquillett, Revis. Tachin. N. A. 1807, P- 80. 



Sturmia albifrons Walker. A medium large species, not fre- 

 quently collected here, adults taken from low foliage. Specimens vary 

 from 7 to 10 mm. in length. Reported from Paris and Waco, Texas, 

 by Coquillett, Revis. Tachin. N. A. 1897, p. no. 



Sturmia distincta Weidemann. One of the more robust species 

 of this genus. Rather common from July to October, but not abundant 

 at any time. Frequently taken from cowpea foliage. Varies from 8 

 to II mm. in length. Previously reported from Palestine, Texas, by 

 Coquillett, Revis. Tachin. N. A. 1897, p. in. 



Sturmia limata Coquillett. Not often collected. Smaller than 

 either of the above species and may be recognized by the shiny black 

 color of the last two abdominal segments. Several specimens taken 

 from low foliage, one from Bacckarius helium folia L. About uniform 

 in size, measuring 6 to 7 mm. in length.
