148 CATERPILLARS AND THEIR MOTHS 



tending to the tip of the horn. The anal shield was 

 edged with white and was bluer than any other part 

 of the body. The legs and props were green; the 

 caudal horn was pinkish in front and green behind. 

 The spiracles were inconspicuous. 



It molted four days later, and was unchanged, but 

 after two days faint red lines appeared above the 

 obliques, the tips of the legs became red, and the yel- 

 low face-lines were very bright. 



It molted again in four days, the only change being 

 a faint black edge added to the face-lines ; but two 

 days later, as often happens with sphinx caterpillars, 

 the colors changed somewhat. The face-lines became 

 pale green edged with faint black lines ; the obliques 

 were white edged above with pinkish lilac ; the horn be- 

 came green with a black stripe on each side ; and the legs 

 were white with red tips. The yellow lateral line dis- 

 appeared from the thoracic segments. The props 

 showed a faint purplish tinge. The spiracles were 

 red. The thoracic segments and the lower parts of 

 the other segments were covered with tiny white dots 

 encircled by black rings. The horn was short in pro- 

 portion to the size of the caterpillar. From this time 

 the crawler ate voraciously and grew fast, and ten 

 days later, when it stopped eating, it was three and a 

 half inches long. 



In this stage luscitiosa is often mistaken for gordlus, 

 especially when found on bayberry or blueberry. One 

 entomologist wrote to the Other of Us that he found 

 on bayberry a larva he supposed to be ffordius, but 

 the pupa gave luscitiosa in the spring, to his very 

 great surprise. Willow and poplar are the usual
