white spots on each elytron (fig. 2) instead of the longitudinal white 
lines which distinguish the latter (fig. 1, ¢). The larva and pupa are 
so similar that no description need be made of them. Although 
the species has a fairly wide distribution, corre- 
sponding somewhat closely to that of the com- 
mon species, specific injury by it has only been 
noted in two States, namely, in Michigan by 
Prof, A. J. Cook and in Iowa by Prof. H. Osborn. 
\ In the former State this borer is reported. as 
‘quite as common and destructive as Saperda 
candida. Its occurrence is recorded, also, in 
Trae 2 sa erddicretqias tte: Canada, Massachusetts, New York, Pennsylvania, 
male beetle—enlarged one- Wisconsin, and Ohio, and there are specimens in 
eee the National Museum from northern Illinois and 
Texas. Apple and wild crab are the only plants which it has been 
observed to injure, but its occurrence has been noted on juneberry 
and thorn. According to Osborn the ‘“‘eggs are evidently laid in 
pairs, half an inch or more apart, along the branch, the larve of each 
pair upon hatching working in opposite directions around the branch, 
at first just beneath the bark, afterwards (probably after the first 
year) entering the hard wood.” 
The remedies for this species are the same as for the preceding 
with the extra precaution that the larger branches, also, be protected 
by the wash applied. 
THE FLAT-HEADED APPLE-TREE BORER. 
(Chrysobothris femorata Fab.) 
GENERAL APPEARANCE AND NATURE OF INJURY. 
A much less dangerous, though more abundant, insect than any of 
the preceding, is the flat-headed apple-tree borer. . It belongs to the 
short-horned wood-borers or metal- 
lic beetles of the family Buprestide, 
and differs remarkably from the pre- 
ceding in all its stages as well as in 
its habits and life history. 
The adult insect (represented at 
b, fig. 3) measures from a little less 
to a little more than a half inch in 
length. It is flattened above and 
bears some resemblance to a snap- 
ping beetle, but, unlike the Elateri-
