 parts of the stems of squash vines and probably other allied plants; 

 M. gloriosa, roots of sumac and the herbaceous climbing stems of Megar- 

 rhiza; Alcathoe caudatum, roots of virgin's bower (Clematis virginiana) ; 

 Sannina uroceri/ormis, roots of the persimmon; Trochilium pacifieum, 

 bores in the cotton wood and probably also the willow; T. tibiale, the 

 trunks of poplar and willow; T. apiforme (a European species), breeds 

 iu the roots and lower parts of the trunks of poplar and willow; Bem- 

 becia marginata, roots of the blackberry and raspberry; Vespamima 

 sequoia', breeds in the California redwood (Sequoia sempervirens) and 

 pines (Pin us lambertiana and P. ponderosa) producing thick excres- 

 cences on the branches and trunks; Sciapteron tricincta,in the canes 

 and trunks of low swamp willows infested with Gryptorhynchus lapathi 

 and Saperda concolor, also in the poplar; 8. denotata, habits probably 

 the same as last species; 8. robiniw, the locust (Bobinia pseudacaeia), 

 also recorded in the poplar; 8. siniulans, in the solid wood of the trunks 

 of red oak; 8. dollii, in the solid wood of poplar and also possibly the 

 willow; 8. polistiformis, burrows in the bark and sapwood of both 

 wild and cultivated grapevines; Tarsa denudata, in the roots and lower 

 parts of the trunk of alder and ash; Parharmonia pini, under the bark 

 of pine; Podosesia syringcv, the trunks of lilac, ash, and mountain ash; 

 7*. fraxini, the trunks of the ash and probably also the lilac; Sannina 

 exitiosa, under the bark of the peach and cherry, both wild and culti- 

 vated, at the base of the tree and very often beneath the surface 

 of the ground; 8. opalescens, feeds like the preceding species, in the 

 trunks of the peach and apricot and probably also the cherry; Sesia 

 rut Hans, in the roots of the strawberry, blackberry, and raspberry; 

 S. bassi/ormis, in the stalks of Eupatorium ; 8. rubrofascia, in the trunks 

 and canes of willow; 8. albieornis, habits like the last; 8. euliciformis 

 americana, in Nevada in the trunks, and stems of alder; 8. acerni,hores 

 under the bark of the maple, especially Acer dasycarpum; 8. corni, 

 under the bark of maple; 8. tipuliformis, in the stems of the cultivated 

 currant, in Europe in the young shoots of hazel; 8. pyri, in the trunks 

 of pear and apple, between the outer bark and sapwood; 8. scitula, 

 under the bark of chestnut, oak, and dogwood, likewise in the oak 

 galls (Andricus cornigerus), and in galls on willow and hickory; 8. rub- 

 ristigma, bred from the oak gall (Andricus cornigerus); 8. sigmoidea, 

 taken from willow; 8. qucrci, bred from galls found on live oak in Ari- 

 zona; 8. pro8opis, raised from galls found on mesquite in Arizona; S. 

 pictipes, under the bark of plum, cherry, peach, plum, chestnut, and 

 juneberry (Amelanehier canadensis); usually bores under the bark some 

 distance up from the base; it also feeds in the black knot fungus;
