The maxilhe themselves {mx) are welldeveloi)ed, but at their base are divided by an impressed line, representing a portion which I amunable to name. The three pairs of feet are easily identified. Tlie outer division of the eye islarge, and the cocoon-breaker, consisting of two solid tliick ridges 011 the vertex, adai)ted forbreaking out of its cell in the tree it inhabits, are well marlud. Abdominal segments 3-7 arefree in the S , and on 3 to (> is a row of spines at each end; on segments 7 and S there are fourtransverse rows of stout spines, and on !) two rows of small spines. There is no cremaster. Onthe underside of segment 8 is a row of about fifteen stout spines, and vestiges of three ])airs ofabdominal legs are distinct. Tlie pupa is ])iovided on the abdomen with a few long seta-. The jmpa of Phassns (fig. 34) is lemarkable. Tiie larva boi-es into a very hard tree, accordingto the late Mr. II.
