is of interest that this larva, which is recorded from the ''Southern 

 and Southwestern States" and Colorado, was found on the prairie 

 of Illinois. It is another example illustrating the southwestern and 

 western affinities and origin of many elements in the prairie fauna. 

 Mr. C. A. Hart informs me that he took the moth at a light Sept. lo 

 and 17, 1909, at Urbana, and that it was taken at Pekin, 111., in August. 



Spragucia leo Guen. 



This little moth was taken once on the flowers of Solidago (near 

 Sta. I, a) Aug. 11 (No. 20); again, in a similar situation, Aug. 12 

 (No. 26) ; and a third time in the cleared area near the Bates woods 

 on the flowers of Pycnanthemiim pilosum (Sta. IV, a) Aug. 23 

 (No. 146, two specimens).

Gnorhnoscheiiia gallcrsolidaginisKiley. (Caterpillar Gall) (PI. XLVI,

This common gall was taken by T. L. Hankinson on Solidago at 

 Sta. I, Aug. 8, 19 10 (No. 7462).

DiPTERA 

 Cecidomyiid/E 



Cecidomyia soUdaginis Loew. (Goldenrod Bunch Gall.) (PI. 

 XLVI, fig. 5.) 



This gall was taken on Solidago Aug. 12 at Sta. I (No. 42), 

 and by T. L. Hankinson at Sta. I, on Aug. 8, 19 10 (No. 7462). 

 This gall forms a rosette or terminal bunch of leaves on Solidago. 



Cecidomyia sp. 



A willow cone-gall was found Sept. 13 by T. L. Hankinson on 

 willows at Sta. I. (Cf. Heindel, '05.) 



CULICID^ 



Psorophora ciliata Fabr. Giant Mosquito or Gallinipper. 



This is our largest species of mosquito. It was taken among the 

 swamp milkweeds, Asclepias incarnata (Sta. l,d), Aug. 10 (No. 

 13) ; and in the prairie grass colony (Sta. I, g) Aug. 12 (No. 44). 

 Both of these places were near moist or wet areas. Individuals were 

 not abundant, although the species is particularly adapted to living 

 where the moisture is variable. Morgan and Dupree (Bull. 40, Div.
