PREDACEOUS BUGS. 121 



the winter of 1872-73, thus proving that the insect hiber- 

 nates as an imago. Different stages of the nymphs have 

 been reared to imagoes at the insectary of the gypsy moth 

 committee ; but, owing to the amount of work involved, we 

 have made no attempt to carefully follow the entire round 

 of life, which apparently does not vary materially from that 

 of serieventris. The imagoes are abundant in the spring, 

 again in midsummer and also in September and October, 

 and there can be no doubt that the species is here double- 

 brooded. P. modeslus is less common than serieventris or 

 placidus, and, so far as my experience goes, is more fre- 

 quently found on bushes and low-growing plants than on 

 trees. In feeding habits it shows the same voracity as 

 serieventris, and preys upon larva? of all sizes. It has 

 been rec'orded as destroying Haltica bimarginata Say (Lint- 

 ner, Fifth Rep. Ins. N. Y., 1889, p. 170), Haltica chalybea 

 III. (Liutner, Sixth Rep. Ins. X. Y., 1890, p. 189), Hemileuca 

 maia Drury (Lintner, Eut. Coutrib., I., 1872, p. 150), 

 Clisiocampa americana Harr. (Kirklaud, Can. Ent., 1897, 

 p. 115), LygoBonematus erichsonii Hartig (Fletcher, Can. 

 Ent., 1884, p. 215). In Professor Feruald's collection there 

 is a specimen of P. modest us taken feeding on a leaf hopper 

 at Amherst, Mass., May 28, 1890. 



In September, 1896, Mr. Robert Cooley took a nymph of 

 this bug at Brewster, Mass., feeding on the pupa? of the 

 "yellow-headed fire worm," Terns minuta. The imago 

 developed September 20. The writer has found modest us 

 feeding on gypsy moth larvae during the past summer at 

 Saugus, Mass. A minute hyuienopterous parasite, Tehno- 

 mus podisi Ashm., has been reared from the eggs of this 

 bug ( Insect Life," IV., p. 123, 1892).
