General ground color olivaceous brown. A white dorsal interrupted line, and 

 two white subdorsal lines. On each joint a transverse row of short black tubercles. 

 encircled by a white line. A long white hair from the point of the black tubercle. 

 On joints 2, 3 and 4 were four tubercles, of which the middle ones were smallest. On 

 joint 5 were four larger tubercles of equal size. On joint 6 were six tubercles, on 

 joint 7 were eight tubercles, of which some very small. On joint 8 were six tubercles, 

 two of which much larger. On joints 9 and 10 also six tubercles, but so small on the 

 last, it was difficult to ascertain exact number. On joint 11 there were four tubercles 

 in the row, preceded by two anteriorly on the dorsum. On joint 1 2 were placed six 

 tubercles in two rows like the preceding segment, but larger. On the last joint four 

 small tubercles. Head black with two wdiite tubercles on occiput. Mouthparts 

 blackish. Thoracic feet black. Clasper blackish. 



August 10 noted a larva of 20 mm. length, 3 mm. width. 



Head oval ; a wdiite triangular mark in the middle. On each side two convex 

 bodies meeting at the vertex, shining, mottled olivaceous and white, covered by a few 

 small white hairs. Mouthparts blackish. On the second joint twelve black tubercles, 

 of which two dorsal and two subdorsal, the largest covered by hairs, and the four 

 lowest crowded together. On third joint are twelve black tubercles, the four upper- 

 most largest, and the lower lateral only one-fourth as large. On joint 4 the same. 

 On joints 5, 6 and 7 the two tubercles each side of central dorsal line are larger than 

 any other of the body. On joint 5 the smallest tubercles number five on each side, on 

 joint 6 are five tubercles near intraspiracular line, rather crowded, and on joint 7 are 

 only four on each side. On joint 8 ten tubercles. On joint 9 and 10 twelve tuber- 

 cles. On joint II ten tubercles, on the penultimate, twelve tubercles. On joint 1 3 

 are a number of minute, scattered tubercles. Relow the clasper two larger black 

 tubercles. Thoracic and abdominal legs black. The penultimate and preceding 

 joint more brownish than olivaceous. Surface of body smooth, shining. 



August 19, most of the larvae perished. The last and largest was 

 28}^ mm. in length, and 6 mm. in width at the middle of the body, 

 and 5 mm. at penultimate joint. 



Longest hairs 4^ mm. in length. The hairs on head and joint 2, as well as on 

 the penultimate and last joint, only half so long. Width of head 3^ mm. Face oval, 

 ornamented by black spots. An irregular black groove between checks and vertex. 

 Eyes black, edged white above. Lips whitish. Ground color ivory white. Pour 

 white longitudinal lines '4 mm. in width, irregular in outline. Infraspiracular line 

 not quite so wide. There is more white color on joints 5 and II than any other. 

 The white of joint 3 uniform in width. Tubercles on all joints longer, otherwise 

 much the same. Joint 12 is much wider than any other. Anal plate irrorated black 

 on white surface. Clasper much the same in color as the prolegs, with black on 

 outer parts. Spiracles black, encircled by a wdiite line. Exterior surface of thoracic 

 feet pitchy black, shining, the same as external surface of prolegs. Inner side of 

 thoracic' feet cinereous. Inner side of prolegs white. Between prolegs the adominal 

 surface is a kind of pinkish ochraceous. On the segment anteriorly to prolegs, the 

 black tubercles edged white, form a continuous band around body, but smaller on the 

 abdominal surface, also hairs or. the abdominal tubercles. The general ground color 

 is more ligneous than olivaceous as previously.
