caterpillars are very active, moving freely about within these silken 



passages from beneath one scale to another. 



At the time my observations were made (June 24th) many of the 

 caterpillars were full grown, and some of them transformed at once. 

 The cocoon is made within the silken tunnel and is quite delicate, 

 the pupa being plainly visible within it. Individuals of this l)rood 

 remained ten days in the pupa state. The greater number of the 

 moths bred by me this year issued July 17tli; some, however, did not 

 appear until August 13th. 



These moths are not easily disturbed ; but will suffer the twig 

 upon which they are to be handled freely without mo\ing ; and 

 often they Avill not take to flight even when touched. They usually 

 rest upon the two posterior pairs of legs and the tip of the folded 

 wings, Avith the front pair of legs drawn closely to the body, and 

 the whole body forming an angle of about 45° with the object up- 

 on which they are at rest. In this position they will remain motion- 

 less for hours. 



Can it be that the slowness with which the coccid can spread 

 has influenced the habits of this species in the adult state ? 



Several of the moths wdiicli issued July 17th were placed in a 

 breeding-cage containing a twig infested with Fidcinarla. July 

 12tli several eggs Avere found. These eggs Avere deposited singly 

 either on the bark, the coccid scales or the cottony masses. In the 

 latter case they could scarcely be detected by the naked eye on ac- 

 count of their resemblance in color to the excretion. Six days after 

 oviposition the eggs hatched. 



I Avas unable to trace the history of the second brood for Avant of 

 eggs or young bark-lice Avitli Avhich to feed the larvae. It is prob- 

 able hoAvever that the habits of this brood are similar to those of 

 the first. I am strengthened in this belief from the fact that I 

 found ncAvly hatched Fulrniaria the day before the second brood of 

 the Fyralicl emerged from the egg. 



This moth belongs to the genus Bakruma of Grote. And as the 



species seems to be undescribed, I propose for it the name co('ci(Uvora.
