THE LARVA OF LIMACODES INORNATA, G. & R. 



BY HARRISON G. DYAR, KHINEBECK, N. Y. 



Larva. — Elliptical and much flattened, the sides rising slightly to two 

 dorsal ridges, only a little elevated, these ridges diverging somewhat 

 towards the anterior and posterior portions of the body. Around the out- 

 line of the body is a series of flattened pointed projections for the last 

 eight segments, furnished on their sides with fine, short hair. These pro- 

 jections occur on each segment after the ftfih, the two on the last segment 

 somewhat longer than the others, and directed nearly straight backwards. 

 Colour green, a reddish line on the angulated outline of the anterior seg- 

 ments ; the dorsal ridges marked with a narrow yellow line, which is 

 interrupted between two dorsal yellow spots with red centres. These 

 spots are conspicuous though small. 



Food Plants. — Maple, wild cherry, hickory, etc. Like most of the 

 'Cochliinfe a very general feeder. 



A good figure of this insect is to be found in Harris's Entomological 

 Correspondence,* and in the text Dr. Harris says : § [The larva is] " in 

 form somewhat like an 07iiscus, being oval and flattened, with lateral 

 tooth-like appendages fringed with hairs. General colour green, with 

 lateral rows of minute, ocellated spots, each pupillated with a black dot ; 

 a dorsal row of dark spots, with two of a rich scarlet colour * * * 

 This insect does nor sting." 



The difference between this larva and that of Limacodes scapha 

 Harrisf is very marked. While L. scapha is a thick larva, resembling a 

 lump of some substance adhering to the leaf; the present species, as 

 above stated, is much flattened, and furnished with its remarkable tooth- 

 like projections. Li fact, before the imagines of L. inornata were 

 developed, I had no idea that the insect could be congeneric with Z. 

 scapha. 



Two males, raised from these larvae, differ somewhat from the original 

 description by Grote and Robinson, | so that^ to them, the name of 

 " inornata" hardly applies. In this form the secondaries are somewhat
