Lcitcania phragtiiitidicola Guen. April i, 8. 



Under boards with other noctuid larvae, and under boards in the 

 Devil's Hole, in bunch-grass. A common and generally distributed 

 species. 



Cramhus sp. (indetemiinable). April i. 



The larva of a crambid moth was taken under a log in a fence- 

 row, with other insects. The crambids are characteristic grassland 

 species, the larvae living in grass roots. Hart found a number of 

 individuals of Cramhus hayticUus Zinck., in the neighborhood of 

 blowouts. The species is described from Hayti, and listed from 

 Texas. Mr. Hart was unable to find other records. 



Pyraitsfidae, sp. (indeterminable). April 7. 



Two larvae of this family found on bare sand, at the base of a 

 clump of sumac, Rhus canadensis illinoensis, from the foliage of 

 which they had apparently been blown (the day being windy). No 

 others were found on the leaves. The larvse were kept from blow- 

 ing about on the sand by means of silk threads. 



Order diptkra 



Helobia punctipcnnis Meig. April i. 



This small tipulid was very abundant along a roadside east of 

 Havana. On April i, not long before sundown, numbers of small 

 Tipulidae were seen near the hedge flying up and down four or five 

 feet above the ground, in the manner described as breeding swarms. 

 They were in groups of from five to ten. 



Chironoiiiidac, sp. (undetermined). April 8. 



The larvse of the chironomid midges are aquatic, and are very 

 abundant in the river. In the spring and summer, large numbers of 

 the adult flies emerge, and are found at considerable distance from 

 the river. Those which get into the Devil's Hole and other parts of 

 the sand prairie must add an appreciable food-element to the associa- 

 tion, like the Bphcincridae and other non-predaceous forms with 

 aquatic larvae. 



Sciara sp. (undetermined). April i. 



Found under log in fence-row. This genus belongs to the family 

 Mycctophilidac, or fungus-gnats, the larvae of which live in fungi or 

 decaying vegetable matter. 



Tabanits costalis? Wied. June 28. 



The horse-flies, as the Tabanidae are called, are swift-flying 

 forms which attack horses and cattle, extracting the blood by means
