370 Description of Ijepidopterous Larvos. 



It is not so common a species as number five, but occurs in limited 

 numbers every season. The spines sting severely. The insect is easi- 

 ly reared, and spins a dense cocoon, surrounded by a more open en- 

 velope, as stated by Packard. This species will readily be recognized 

 by the green saddle-like marking of the dorsal surface, with the oval 

 spot in the center, as Avell as by the curious development of the thor- 

 acic segments. Altogether, it is one of the, most grotesque and beauti- 

 fu 1 objects among lepidopterous larvae. 



Number seven. Limacodes — ? Larva oblong oval, slightly atten- 

 uated posteriorly. Dorsal surface flattened, highest in front. Dorsal 

 keels ornamented with eight pairs of rose-colored spiny tubercles, of 

 which the eighth pair is much longer than the others, as well as lighter 

 in color. Dorsal surface beautifully clouded with five oval spots, of a 

 chocolate brown color, surrounded by a narrow rose-colored band, the 

 third from the front being the largest, and extending over the dorsal 

 keels slightly below the spines. First three spots separated from the 

 last two by a slight, yellow, transverse space. The whole upper sur. 

 face, between the oval spots and around their ends, is light, yellowish 

 green. Lateral surfaces pea green, bordered above by a yellowish 

 green line below the dorsal keels. Under surface light dirty green. 

 Head and mouth parts brown, and concealed under the hood except 

 when crawling. The second and third thoracic segments are then seen 

 to be light pea green. Thoracic legs white and very minute. Thor- 

 acic segments bearing a few, scattering, whitish hairs. Length, when 

 extended, § inch. Breadth, at sixth segment, /g inch. Oct. 8, 1875. 

 Acer saccharin um. One specimen. 



Eemarks. This extremely elegant little species, so different from any 

 of its allies, was found on the under side of the leaf on the date 

 above mentioned. It may be recognized very readily, as the beautiful 

 (^oloring of the dorsal surface, the row of chocolate brown spots, sur- 

 rounded by the rose-colored band, and the beautiful golden green of 

 the remaining space, sufliciently point it out as distinct. As the 

 larva is yet feeding, I am unable to describe the cocoon. This is much 

 the smallest species I have ever seen, and by far the most active. If 

 undescribed, it may by called L f 7}ebulosus. 



Number eight, Limacodes — ? Larva oval-quadrate, with the dor- 

 sal and lateral surfaces flattened, and bearing, attached to the lateral 

 margins of the dorsal surface, nine pairs of flat, fleshy appendages, 

 .clothed with stiff, bristly hairs, light brown on the upper surface, and 

 dark velvet brown beneaUi. Of these api)endages the third, fifth and 

 seventh pairs project beyond the others, at lea it two-thirds their lengtli. 



Of the remaining pairs, the second and eighth are the longest, and
