62 THE CAXADIAN ENTOMOLOGIST. 



The under surface was similar in color to the upper. I was not able 

 to detect any trace of feet, although a careful examination was made 

 with a lens. 



No further observations on these larvae Avere made until May 2, when 

 I expected to find them in the chrysalis state, but was surprised to find 

 in the several cells I opened that no pupal enclosure was to be seen, but 

 that the head, antennae and legs were fully developed, while the wings 

 and wing cases were only partiall}^ so. The wing cases, which covered 

 the membraneous wings, were not more than one-eighth of an inch long, 

 and projected out over the sides, spreading almost free from the body. At 

 their base they were yellowish and semi-transparent, while from about the 

 middle to the base they were black and covered with the usual small 

 granulations. The scutellum was indicated by a short black streak 

 widening anteriorly, while behind this the body was of a dirty yellow 

 color and soft, flabby consistence. This color and consistence prevailed 

 below also, behind the base of the legs, while about and anterior to them 

 the color was black. The insect could move its legs, but was very 

 sluggish and did not seem disposed to move at all unless disturbed ; at 

 this stage it was incapable of walking. Several of the chambers, which 

 had been opened with care, were closed and tied up with their occupants 

 in them ; these were examined again on the 9th of May, when the abdo- 

 men was found to have decreased in size and become uniformly dark, 

 almost black below, with the surface roughened, but still yellow at the 

 tip. Above there was a large black patch behind the scutellum, covering 

 nearly one-third of the body, and another large black spot near the tip, 

 covering the loth and nth segments, while the interspace between these 

 two segments was of a dark greenish hue ; the elytra had lengthened so 

 far as to cover about two-thirds of the abdomen. The beetle was more 

 iictive now, and able to walk, although with difficulty. 



On the 1 6th of May the wing cases of one were found of full length, 

 but not fully expanded so as to cover the body, while in another case they 

 were fully developed. The twigs containing these insects had been 

 allowed to remain in a dry room without any means being taken to keep 

 them moist, hence they had become quite dry and brittle. On the 24th 

 of May a fresh bundle of twigs was received from Mr. Bucke, and in 

 these, while the greater number appeared to have been eaten by wood- 

 peckers, some five or six specimens were found in a state of chrysalis 

 one cell was occupied by the pupa of some parasite.
