thy seeds, the prairie grass Panicum crusgalli Linn., and even a small 

 beetle, Ips 4-guttatus Fabr. He also observed H. caliginosus feed- 

 ing upon seeds of ragweed, Ambrosia artemisiifolia. (See Forbes — 

 '80, pp. 156-157 and '83a, pp. 45-46 — for further- observations upon 

 the food habits of the beetles of this genus.) Clarkson (Can. Ent., 

 Vol. 17, p. 107, 1885) observed caliginosus feeding upon ragweed 

 on Long Island; and Hamilton (Can. Ent., Vol. 20, p. 62, 1888) re- 

 cords similar observations for this beetle and for pennsylvanicus. 

 Both species are reported to injure strawberries. Coquillett (Insect 

 Life, Vol. 7, p. 228, 1894) observed caliginosus feeding upon a 

 grasshopper. 



COCCINELLIDyE 



Hippodamia parenthesis Say. Parenthetical Ladybird. 



This insect was taken only by T. L. Hankinson (Sta. I) July 3, 

 191 1 (No. 7665). 



Coccinella novemnotata Hbst. Nine-spotted Ladybird. (PI. XLIV, 

 fig. 2). 



This insect was taken on the common milkweed, Asclepias syri- 

 aca, (Sta. I) Aug. 12 (No. 27). This species is another example of 

 one of the commonest insects to which so little attention has been 

 given that we really have no full account of its life history and ecol- 

 ogy. Many scattered observations have been made, but none are ex- 

 tensive. Forbes examined the stomach contents of five specimens 

 and found that they had eaten plant-lice, fungus spores, and a few 

 lichen spores ('80, pp. 1 57-159. and '83a, pp. 53-54)- 



LAMPYRID.ffl 



Chauliognathus pennsylvanicus DeG. Soldier-beetle. (PI. XLIII, 

 figs. 5 and 6.) 



This is one of the most abundant beetles found on flowers in late 

 summer and fall, particularly upon goldenrods (Solidago), and 

 other composites. The first specimens were taken in a cleared area, 

 with much sprout growth and open patches, where the mountain mint 

 Pycnanthemum pilosum abounded, (near Sta. IV, a), Aug. 23 (No. 

 146). On the following day they were first found on the prairie — 

 copulating as usual — on the flowers of the swamp milkweed, Asclepias 

 incarnata (Sta. I, d), Aug. 24 (No. 156.) 



They were taken from the flowers of the broad-leaved rosin- 

 weed, Silphium terebinthinaceum, on the prairie east of Charleston 

 (Sta. Ill, b) Aug. 26 (No. 175), and on the Loxa prairie (Sta. II,
