SUBFAMILY I. — PENTATOMIN^E. 99 



trees and shrubs and in cool rainy weather in summer and fall 

 congregates in small colonies beneath loose bark or other shel- 

 ter. Hibernates as imago beneath bark and logs, lying dor- 

 mant for months with antennae folded back along the breast; 

 frozen solid during zero weather, then — its circulating fluid 

 again brought into motion by the genial sunshine of spring — 

 creeping forth to find for itself a mate and perpetuate its kind. 



Dunedin, Fla., March 18, one specimen ; recorded also from 

 Pablo Beach, Lagrange and Enterprise, Fla., but much less 

 frequent in that State than farther north. Sherborn, Mass., 

 Oct. 25 (Frost). Ranges from Quebec and New England across 

 the continent to California, Utah and Arizona, being most 

 abundant in the States north of latitude 37 degrees. Hart 

 (1919, 173) states that in Illinois: "It rests on the branches 

 of trees protected by its color. We have found it on elm and 

 grape, but it has been noted especially in orchards on apple and 

 cherry trees. Sanderson has recorded it as preying on the 

 tussock and brown-tail moths ; but its abundance in all stages 

 on trees suggests that it may also feed on the sap ; ... as 

 it has been found very abundant on apple trees injured by twig 

 punctures." Howard (1895, 47) records the receiving from 

 Virginia of specimens of a large Pentatomid bug (Brochymena 

 annulata Fabr.=5. quadripustulata Fabr.) which had attacked the 

 new growth of apple trees in May, pumping up sap from the 

 tender wood, many twigs and limbs being killed. Brimley 

 (1907, 441) found it "very common in North Carolina under 

 bark of dead pine in company with wasps of the genus Polistes." 



The eggs of this and allied species of Pentatomids are, in 

 form and structure, very interesting and attractive little ob- 

 jects. A cluster of 44 from which the young of quadripustulata 

 were just emerging, was found July 23 in a dense woodland 

 near Indianapolis. The eggs were set closely together in rows 

 on the under side of a leaf of skullcap, Scutellaria nervosa Pursh., 

 each one having its lower end attached by a glutinous secretion 

 to the leaf. The shells were pure white in color, of a minutely 

 granulated texture and cup-like in form, each being slightly 

 constricted near its upper end with the rim very finely, evenly 

 and prettily ciliated. The closely fitting top was circular and 

 feebly convex and was being pushed upward and backward, as 

 if on a hinge, by the very homely little bugs as they emerged 

 to get their first glimpse of the great out-of-doors.
