The bunch of twigs received Mar. 25, as above stated, were 

 examined by Mr Saunders May 2, when he found that no pupal 

 inclosure was to be seen, though the head, antennae and legs of 

 the beetle were fully developed, while the wings and wing cases 

 were only partially so. On ^lay 16 the wing cases of one 

 beetle were full length but not fully expanded, while in another 

 case the}' were fully developed. The twigs containing these 

 insects had been kept in a dry room and hence they were quite 

 dry and brittle. Fresh twigs received ]\Iay 24 showed that a 

 considerable number of the occupants had been eaten by wood- 

 peckers, though st)me five or six specimens were found in pupal 

 cells, one of which was occupied by the pupa of a parasite. The 

 pupa of this Saperda has been described by Mr Saunders as 

 follows : 



Body semitransparent ; color uniform pale yellow, except the 

 eyes and mandibles, which were black; the jaws were faintly 

 tipped with broAvn and a faint brown line down each side of the 

 scutellum. All the parts of the insect were plainly visible 

 throughout the pupal case. The wings were very small and 

 diverged to each side of the scutellum. 



May 29 two of the pupae from the fresh lot of twigs had 

 become perfect beetles, and early in June all had completed their 

 transformations and escaped through neat round holes.
