Wlien first transformed, in 

 May and June, the youn<]: hec- 

 tics have very soft, deUcate tis- 

 sues. They therefore remain 

 in their pupa case.'? until their 

 bodies are fully hardened or 

 cliitinized. AVIumi nearly ready 

 t ) emerfje, the adults hore their 

 way almost to the sui'face of 

 the hark (fifj;. 12, d), hut pause 

 before emer«!;ini:;, ai)pearinti; to 

 rest in the burrows they liave 

 just made. They do not, how- 

 ever, lioUow out the space im- 

 mediately adjoining]: the pupa 

 case, as is the liahit of another 

 species of this jjenus. When 

 quite ready to emertije, the bee- 

 tles continue their burrows out 

 throu<i:h the remaining; jiortion 

 of the bark. The individuals 

 of a brood do not appear to 

 emert^e sinndtaneously, but 

 they come forth at irre<;ular in- 

 ters''als unt il all are out, leavintr 

 the bark thickly punctured wit li 

 small, round, clean-cut holes. 

 as shown in fijjure 12.

 tles lly away to find tre(>s in 

 which to deposit e«;<;s. They 

 may select trees close at han<l 

 or may lly tpiiie a lon«;distance before making' a select 

 al.so enter the ii\ inir bai"k of recent 1\- felled trees. L
