DOLBA HYLyEUS 



GENUS, DOL'BA. 



SPECIES, HYL^'us (a centaur. There is no appropriateness). 



It was a joyful day for us when one of the children 

 brought us " a gray little moth, not a bit pretty. Per- 

 haps you don't want it." We did want it, and gladly 

 paid the price offered for " anything we want very 

 much," for no description of Bolha hylceus' early stages 

 had been published, and this was an egg-layer. 



The eggs were pale green, oval, and grew yellowish 

 five days after they were laid, hatching on the seventh 

 day. 



The caterpillars were less than a quarter of an inch 

 long, green, with black caudal horns nearly as long as 

 their bodies. They would eat nothing but inkberry, 

 Prmos glabra, and after feeding they grew pinkish, 

 especially near the head and horn. They spun threads 

 as they crawled, and some died from being entangled 

 in these threads, so we separated the rest, having only 

 one or two in a box. 



They fed for a week before molting, then molted, ate 

 all their cast skins, and looked just as they did before, 

 only longer, but in a day or two tliey showed faint 

 white subdorsal lines from head to horn. The horn 

 was black, the segment at its base whitish green.
