INSECUTOR INSCITI/-E MRNSTRUUS 199 



two other species occur in the flood-pools, although not breed- 

 ing exclusively in them. These are Acdes vexans Meigen and 

 Acdes cinereus Meigen, both common to America and Europe, 

 and not at all particular in their habits. I made a visit to 

 Mission City, British Columbia, July 14, 1930, where Mr. 

 Hearle very kindly took me over the ground and explained 

 the problem. All three species noted above occurred, the first 

 two in abundance, the latter rarely. The adults were on the 

 wing at this time, although some larvae were left. Specimens 

 from this breeding were taken at Sumas, Washington, July 15, 

 1920 (H. G. Dyar). 



Similar floods occur in the lower Columbia River, In 

 passing Vancouver, Washington, on the train, high water was 

 noted, and a trip to a forest in the general vicinity resulted in 

 showing both aldrichi and vexans well spread in the timber. 

 Specific locality for both species: Montavilla, Oregon (6 miles 

 east of Portland), July 36, 1930 (H. G. Dyar). I have also 

 both species from Hood River, Oregon, vexans, July 17 and 

 September 34, 1917 (F. R. Cole), the latter worn and almost 

 unrecognizable, and aldrichi, June 13, 16, 30, and July 7, 1917 

 (F. R. Cole). 



It seems possible that A'edes goninms D. & K., from Kerr- 

 ville, Texas, is a flood-species allied to aldrichi. The mark- 

 ings are similar, the dark mesonotal stripes narrower, the 

 ground color more golden. The region about Kerrville is sub- 

 ject to floods, being in a region of low hills of coral rocks. 

 However, nothing certain can be said until the male has been 

 discovered.
