Galerucella notulata Fab. Taken on ragweed (Ambrosia), July 6. 



Oedionychis 6-maculata 111. Abundant on foliage of ash, together 

 with O. scalaris, April 5. This beetle is astonishingly quick in its 

 movements. 



Oedionychis scalaris Melsh. Taken on ash, but not as abundant 

 as the above species. April 5-6. 



Oedionychis fimbriata Forst. Beaten from oak foliage, April 18. 



Disonycha glabrata Fab. Abundant on bull thistle while in bloom, 

 April 20. Large numbers riddling the foliage of pigweed (Amaranthus) , 

 May 15. A few were taken on corn plants, August 16. 



Disonycha triangularis Say. Taken by sweeping low foliage; 

 moist hammock edge at target range, April 15. Taken under old log 

 hibernating, (C. Nieland). . 



Phyllotreta picta Say. Very abundant on young oak foliage, 

 March 10-April 2. 



Haltica chalybea 111. This species winters over in the hammocks in 

 Spanish moss. An adult was taken as early as February IS, at wild 

 plum blossom and by the 27th large numbers were beginning work 

 on the foliage of the wild grape. Hundreds were swarming everywhere, 

 May 5. 



Blepharida rhois Forst. Adults and larvse of this "jumping sumac 

 beetle" were very abundant on young sumac April 11-15. Larvse were 

 al§o abundant September 29, so that there must be a number of broods 

 per year. 



Chaetocnema confinis Cr. Occurs in abundant numbers in the 

 hammocks on the foliage of basswood, wild cherry, buckeye, and various 

 other trees and shrubs. March 3-April. 



Octotoma plicatula Fab. The first of the season was taken on buck- 

 eye leaf, March 6. The ash is their first choice as a food plant and by 

 March 25 large numbers are at work on this plant. They are to be 

 found for only a few weeks and as far as I have observed, have only a 

 single brood a year. 



Chalepus rubra Weber. Several have been taken between leaf- 

 tyer's old nests in the hammock on oak from June 25-March 2. They 

 begin to get abundant on the linden or basswood, the foliage of which 

 they eat, by the middle of March. As with the above species, they are 

 present in numbers for only a few weeks and then disappear. A single 

 specimen was taken on oak, May 1. A pair of this species was taken 

 on linden in copula, June 11. 



Chalepus notatus Oliv. A few of this scarce beetle have been taken 

 on blackberry, Ostrya, and oak. April 4-5. 



Chalepus bicolor Oliv. Two specimens were taken by sweeping low 

 foliage at hammock edge, April 1. 



Metriona (Coptocycla) purpurata Boh. This species has been taken 

 on buckeye, oak, and wild morning-glory vines. March 15-May 15. 

 It is rather uncommon and its favorite food plant is Ipomoea.
