. Bulletin - New York State Museum. Science. MONOGRAPH OF THE GENUS SAPERDA 59 distinct and not even closely related. It is longer in proportion to its width than tridentata. The sides are parallel, while in tridentata the humeral angle is quite pronounced. The first crossbar is oblique, there are no spots on each side of it, and the spot is also lacking behind the apical crossbar; it also wants the submarginal carina present in tridentata, which has the first crossbar at right angles. The pygidium of the female is broader at the top, and the sides make a wider angle than that of tridentata. D

This species has been received from Montreal Can.; and Mr Fred Blanchard has taken a specimen at Tyngs-. Fig. 5 Last dorsal segment and apex of elytra of S. tridentata (a) and S. im itans (fi) boro Mass. Mr Roland Haywood has taken it near Boston; specimens have been seen from Virginia, Michigan, Pennsylvania and Wisconsin; and we have bred it from New York city and vicinity. Saperda lateralis Fabr. Red-edged Saperda This species is about the same size as S. tridentata Oliv. and like it occurs in elm. Its principal food plant is hickory, on which it is partial to injuries near the roots and to the base of sprouts on recently cleared lands. It is rarely abundant enough, however, to cause serious injury. Life history. Comparatively little has been published con- cerning the life history of this species. The beetles may be taken in June in northern localities, and, like most other Saperdas,.
