PROC. ENT. SOC. WASH., VOL. 21, NO. 3, MAR., 1919 53 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.
