Tachinid.^ 



Cistogaster iminaciilata Macq. 



A single specimen of this fly was taken on the flower of rattlesnake- 

 master, Br yngium yucci folium (Sta. II) Aug. 13 (No. 55). 



The larva is parasitic on lepidopterous larvae (Townsend, Psyche, 

 Vol. 6, p. 466. 193) ; and has been bred from the army-worm, Leiicania 

 unipuncta Haw. Two undetermined species of tachinids were taken 

 by T. L. Hankinson (Sta. I) July 3, 191 1 (No. 7665). 



Trichopoda ruficauda V. d. W. 



A single specimen of this fly was taken along the railway track 

 (Sta. I) Aug. 12 (No. 38). 



An allied species, T. pemiipes Fabr., has been bred from the 

 squash-bug (Cook, Rep. Mich. State Board Agr., pp. 1 51-152. 1889), 

 and another, phunipes Fabr., has been bred from a grasshopper, Dis- 

 sostcira vcmista Stal (Coquillett, '97, p. 21). 



SCIOMYZID^ 



Tctanoccra plumosa Loew. (PI. XLVIII, fig. 2.) 



Taken in a colony of Spartina (Sta. I, a) Aug. 28 (No. 179). 

 This species is figured by Washburn (Tenth Ann. Rep. State Ent. 

 Minn., p. 121. 1905). The larvae of this family are aquatic. Need- 

 ham (Bull. 47, N. Y. State Mus., pp. 580-581, 592, PI. 14. 1901) 

 describes and figures T. pictipes Loew. (Cf. Shelford, '13a.) 



Trypetid^e 

 Buaresta cequalis Loew. 



This insect was taken in sweepings among a colony of the cone- 

 flower, Lepachys pinnata (Sta. I, e), Aug. 12 (No. 40). Marlatt (Ent. 

 News, Vol. I, p. 168) records the rearing of this fly from the seed-pod 

 of the cocklebur (Xanthium). 



EmPIDID/E 



Bnipis claiisa Coq. 



A specimen of this fly was taken from a pair of copulating ambush 

 bugs, Phymata fasciata, on the flowers of Solidago (Sta. I) Aug. 12 

 (No. 43), and great numbers, so many that they darkened the flowers 

 on which they rested, were seen upon Asclepias syriaca (Sta. I) Aug. 

 12 (No. 27). The specimen was determined by J. R. Malloch. 



McAtee (Ent. News, Vol. 20, pp. 359-361. 1909) gives an account 

 of the habits of Bmpididcc, and Schwarz (Proc. Ent. Soc. Wash., \'ol. 

 20, pp. 146-147. 1893) states that one kind captures small flies, and
