and illdefined blackish brown spots on the cell, another more denned black 

 spot at the end of the cell; at apical third is an indistinct yellowish costal 

 streak and around the edge is a postmarginal black line on the base of the cilia ; 

 cilia light gray. Hindwings light fuscous. Abdomen dark fuscous with 

 yellowish anal tuft. Legs blackish fuscous with narrow ochreous annula- 

 tions. Alarexpance: 12mm. 



Habitat: Victoria, British Columbia. 

 U. S. Nat. Mus. Type No. 22110. 



Received from Mr. W. Downes. This is the socalled "Straw- 

 berry Crownborer," on which there is a considerable economic 

 literature, but which has never received a specific name. The 

 species is exceedingly close to Aristotelia absconditella, Walker, 

 which feed on Polygonum; the lighter colored terminal joint of 

 the labial palpi and minute differences in the white annulations 

 of the antennae are the only slight distinctions, but slides of the 

 male genitaliea prove the separation correct. 



In the National Museum are also specimens bred from straw- 

 berry at Corvallis, Oregon. 



AVOCADO SEED WEEVILS. 

 BY H. S. BARBER, Bureau of Entomology. 



Since the writer's 1912 note on the large weevil (Heilipus 

 lauri Boh.) reared from Central American seeds of avocado, 

 (Per sea spp.} a federal quarantine has become effective against 

 importation of these seeds, and in this connection the weevil 

 has been mentioned several times. Together with three other 

 seed-infesting weevils mentioned hereafter, it was used in the 

 seed fumigation experiments described by Sasscer 1915. A recent 

 paper by Hoyt 1918 warns the avocado growers of Florida against 

 this possible pest and mentions the feeding injury by the adult 

 in confinement but no field observations (except those of Gandara 

 and Inda 1914, in which the damage by some bark-borer and 

 perhaps other pests also seems to have been confused with that 

 by Heilipus} have yet offered us any basis upon which we may 

 satisfy our curiosity as to the nature or extent of commercial 

 damage liable from this weevil under its most favorable condi- 

 tions. We are still in ignorance of the principal part of its biology 

 since the only observations of which I am aware are based upon 

 prepupal larvae and pupae found within imported seeds and 

 upon the adult beetles issuing thereform. One of these latter 

 lived under my observation for four and a half months, most 

 of the time confined upon a potted seedling avocado about 14 

 inches high, which it killed by its voraceous feeding upon the 

 leaves, buds, and finally upon the bark. Before being placed
