sapwood. The adult leaves the pupal chamber through the 
same opening as that through which the larva gained access, 
and on reaching the level of the bark, there constructs an 
oval emergence hole. Two years are required for the com- 
pletion of the hfe history. 
The associated insects are the same as for Neoclytus 
longipes given previously and it seems unnecessary to repeat 
the list here. 
Chrysobothris sex-signata Say. 
Chrysobothris sex-signata, according to Horn (1886, 
p- 112), “ Occurs from New York to Virginia, westward to 
Nebraska and Indian Territory.” Blanchard (1889, p. 31) 
records it as occurring in New England but as “rather 
searce.” Blatchley (1910, p. 791) also speaks of it as scarce 
in Indiana, although he lists it from five countries. 
No record of this insect actually having been bred from a 
conifer was found, but Blanchard (1889, p. 31) has beaten 
it from pitch pine. Chittenden (1889, p. 219) records it as 
having been “ cut from a beech tree in which it had bred.” 
Smith (1909, p. 293) reports it “on beech, birch and chest- 
nut.” This species, like many others of the same genus — 
and indeed many other genera of buprestids — doubtless 
breeds indiscriminately in a large number of trees, both 
broad-leaved and coniferous. The authors have not only 
obtained a number of specimens from larch, but also have 
bred large numbers from hickory. 
The female chooses the same sort of material in which to 
deposit her eggs as does C. blanchardi. The burrow made 
by the larva is quite variable. Sometimes it is only mod- 
erately coiled as in Fig. 26, while in other cases it is so 
tortuous that it is impossible to trace its course throughout 
its entire length, owing to the fact that the larva crosses and 
recrosses its old track. The burrows, when they can be 
traced, are usually readily distinguishable from those of 
C. blanchardi by their being actually broader and relatively 
shallower. The length of the burrows of C. sea-signata is 
more often less than those of the sister species, but this varies
