ash billets placed indoors in April yielded some young beetles on 2nd 

 August, others having previously emerged and escaped. A second 

 generation may occur, but only exceptionally. With regard to I-ps 

 {Tomicus) typograpkus, L., and I. (T.) amitinus, Eichh., it is known 

 that eggs, larvae and pupae occur together (as a result of slow 

 oviposition and rapid embryonic developm.ent) and it is possible 

 that the first eggs laid may produce a second generation, which is 

 not the case with eggs found in August. Under exceptional conditions 

 a third generation may occur.

 Many years' experience have showTi the following method to be 

 satisfactory against Anthonoinus p)ornorum. The tree- trunks must be 

 cleaned with lime wash and the ground beneath the branches strewn 

 in February with half a wheelbarrowful of gallnut meal, a waste 

 product from tanneries. The strong odour, the tannic acid and tannin 

 content of this substance prevents any insect from reaching the trunk. 

 Mice also are repelled and moss and weeds disappear, making way for 

 grass and clover.

A caterpillar found in coffee plantations in the Brazilian State of 



S. Paulo has been identified as that of a moth, Megalopyge lanata, StoU. 



It is not peculiar to coffee, but injury may result in cases of severe 



infestation.

By cutting off the ends of the cocoon of a moth, PeropJiora packardi, 

 and removing the larva, the cocoon, after being washed in soapy water, 

 dried and soaked in aromatic alcohol for a few days, is said to provide 

 an excellent cigar holder, very resistant to the action of the teeth. It 

 is stated that a German cigar factory has offered to purchase large 

 quantities.

Against the beetles, Lytta (Cantharis) excavata, Klug, and an un- 

 identified species of the same genus, which attack potatoes in Brazil, 

 collection is advised, especially in the early morning when the insects 

 are torpid.
