THE DISTRIBUTION OF INSECTS IN NEW HAMPSHIRE. 347 the early part of July, 1869, Mr. Sanborn searched very carefully for the chrysalids of this species, spending ten or twelve hours in raising mova- ble surface stones, and in four or five places clearing away to the depth of several feet the smaller blocks of stone lying in the " rock rivulets/' as he appropriately terms the slight gulleys wholly devoid of vegetation, which are scattered everywhere over the plateaus, and which mark the course of the surface waters after rain. He succeeded in securing only two living specimens. Nine others were either infested by ichneumons (Eidopluis semidem Pack., and Encyrtus Moatimis Pack., described below*), or were the empty shells of the previous year. They were all found imbedded between the sides of the rock and the long, dense, crisp moss surrounding it, between half an inch and an inch and a half below * "Euh/>hus semide<2 nov. sp. [Fig. 46]. Belongs apparently to the same section of the genus as E. ameni^- S27nus Walk. "o (t^vo specimens). Antennas filiform, not increasing in width toward the tip, rather long, much longer than in E. ameiupsimus, and very hairy, dark brown. Head deep blue, shining, punctured as usual, under a not powerful lens; mandibles, and other mouth parts, pale piceous ; thorax, as well as the whole body, deep blue; fore wings broader at end, clear; spur distinct, dilated at tip; coxa concoiorous with body; trochanters and femora brown, tips of latter pale testaceous; tibiEe brown, pale at tip, or almost wholly pale; tarsi dark on terminal joint, the last joints of hinder pair dark ; abdomen as long as the thorax, narrow lanceolate oval, subacutely pointed, more so than in E. antevipsivius, concoiorous with rest of body, but with steel b
