hit^her tli:in those on the 2d ami jtl thoracic sejjnients, and con- 

 nected 1)\- a tliitinoiis hand, beconiiny; more distinct in stages 

 II and III. The ist and Stli abilominal segments are reddisli, in- 

 cluding^ the pair ni dorsal tubercles which are of the same size. 

 'I'he end of the body is held nj), nuich as in the fullv Ljrow n larva, 

 and I mistook it for a Si/iizi/ra larva, until after it had molted, as 

 the tubercles are conical in this sta.^e as in freshl\' hatched 

 Si/iizi/id* In some individuals the greenish dorsal tui)ercles are 

 dark at the tip. 'I'he glandular hairs are bulbous at the tips, and 

 a few at each end are nearly one-half as long as the body. 



Three days after, June 27, they became 5 mm. in length, the 

 head now small and the larvae were prejiaring to molt; anil July 

 29-30, three cast their skins. 



S/a^^r II. — Length. 4-5 mm. at first. Now the body is like 

 dark opaipie varnish in hue. The head is ilark reddish varnish or 

 pitchy in hue, and decidedly narrows above, bearing two blunt 

 knobs on the vertex ; it is now wider than the body. The pro- 

 thoracic shield is larger than before. The sides of the 2d and ^d 

 thoracic segments are yellowish with reddish lines, and on the 

 sides of the 7th abdominal segment is a \rd\r of lobetl bright straw- 

 yellow spots converging behind, ami lower down are three yellow 

 tubercles tipped with brown. There is a similar single vellow 

 tubercle on each side of the 9th segment. The |:)rothoracic dorsal 

 tubercles are somewhat smaller than those on the ist abdominal 

 egment, and the 8th pair are also a little smaller, but all the other 

 tlorsal tubercles are still large and conspicuous.

The following description of two larvi^i fiuuid at Brunswick, 

 Maine, on the red maple, Aug. 14, describes the peculiar mimicing 

 coloration better then those hitherto published. 



Full-gnnon larva. — Length, 28-30 mm. \\'onderfully mimics 

 a dull blood-red portion of a leaf whii h had been cut partly off 

 and become somewhat twisted, so that the larva itself woukl easilv 

 be mistaken for such a part of a prominent terminal leaf. The 

 deception was perfect, as I did not myself at first see it when 

 within ten inches of my eyes, and on holding it before the eves of 

 an observing boy of thirteen he could not at first distinguish it as 

 a caterpillar. The same leaf had blotches of dull red, anil the 

 flesh-red abdominal feet of the caterpillar clasjied the concolorous 

 red leaf-stalk. One larva was much tieeper blood-red in color 

 than the other, the latter having a more faded tint.
