Extract

Eighth stage.—Head shining black, yellowish punctured around the mouth, antennæ yellowish; eye and jaws black; width, 1.8 mm. Body ochreous yellow, 6-annulate with irregular quadrate sub-dorsal (two per segment) and lateral (one per segment) black spots, confluent on joint 13; sub-ventral ridge faintly discolured; anal plate blackish. No white secretion. The larvæ do not feel in this stage, but seek for soft wood in which they bore their galleries for pupation.

* I have seen the larvæ which he describes, but their structure and position are like those of the species of Emphylus which I have bred. My larvæ died.

* The eighth stage was not noted. It probably escaped observation, as there should be no increase in size of the head, and I neglected to isolate one larva.
