To sum up the essential known facts concerning" the life, liis- 

 tory and liabits of tliis beetle: 



The eji'g'.s are laid preferably at tlie ba.ses of the leaf stem.s, 

 on trees that are sickly. Live trees are, however, occasionally 

 chosen as are also dead and even prcstrate ones. The female 

 cliooses for ovipositing some point where the newly-hatched larva 

 will not have to perforate the liard trunk. 



Xo description of the egg has been given. The larvae take 

 two seasons for complete development, emerging during the second 

 summer, the favored month being July. Some may emerge in 

 June and delayed specimens occasionally hold over until the last 

 of August. 



The larvae feed on tlie pith of the palm, boring their way 

 through every portion of the tree trunk except the hard outer 

 bark. 



They can be heard at work, cutting the fibres with their stout 

 mandibles. Their tunnels are completely filled behind them, as 

 they burrow, with sawdust and frass. 



As they approach the pupal stage the larvae work towards 

 the outer bark, where their pupal chamber is formed at a depth 

 of one-lialf to one inch from the surface. 



The number of moults of the larva has not been recorded. 

 I have observed one such casting in a j^artly grown larva. This 

 occurred on Augu.st 17th, the specimen having remained dormant 

 for three days. It was at this time one and three-quarters inches 

 in total length, dorsal measurement. The skin was split in much 

 the same manner as is common to most beetle larva. All parts of
