 or Slicker, which is used effectively whenever the liruh is forced 

 to travel over a suiooth surface, such as ulass oi- tin. 



The larvae molt in tive to eii-ht days after halchiiii;- as coiu- 

 paiH'd to liilev's four to nine days for this instar""'. The second 

 staiie larvae molt iu four to ten days — Riley's time four to 

 seven days, 'idie thii'd stai^c is ])assed in five to eiuht days — 

 Kilev's three to six. The f(!urth staii'e larvae molt in three to 

 thirteen days, ai^ainst Riley's thrt'c to six. The fifth instar 

 re(iuire(l five to eiglit days — liiley's tive to seven days. The 

 sixth was six to nine days — Riley's six days. 



Under normal conditions the larvae are fully developed 

 after the sixth molt and at (nice seek a i)lace to ]iu]>ate: they 

 leave the food and bore into any substance at hand. It is at 

 this stage that they do damage to cork, etc., even boring into 

 hard ])lanks, if nothing else oft'ers a hiding ])lace in which to 

 ])upate. Roth their habits and structure make it ai)i)ear that 

 the ])upae are jireyed upon in their natural development. 1 he 

 last larval skin bears a transverse row of s])ines alxive on each 

 of the posterior segments, as Riley has noted, and tliese ])ro- 

 iect outward, after the skin is shed and crowded into the 

 opening of the ]iupation burrow. From our observations there 

 are no indications that the pupae of this sj)ecies ar(> destroyed 

 by the larvae, even when they are left exposed. 



Pk/xi: — The pupal period here lasts for ten to eleven days, 

 while Ililey found that this stage reipiired fourteen days. 



There are similar ])ockets on the dorsum of the abdomen 



, to those that are found in Al/df/ciuis /iJchiu.^. In this ease, 



however, there are only hve in place of six, as found in that 



s])ecies, and tho they bear chitinized edges tluy lack the teeth. 



* It was noticeable that where food was abundant, development was 

 rapid, while a scarcity of food not only lengthened the period for each 



of the several instars. but. in some cases, greatly increased the numl)er 

 of molts.
