the Salle collection. Two other specimens are in the U. S. 

 National Museum collection, one of which was found on an 

 aguacate at Ontario, California, November 22, 1911, by Mr. 

 S. A. Pease, while the other w r as found in an aguacate seed in 

 St. Louis, Missouri, by Mr. Clay E. Jordan. 



Subsequent to the presentation of this note, further ob- 

 servations were made which would best be added. 



On May 2, the greenhouse attendant found another adult 

 in a spider web near a pot containing several avocado seeds 

 and noticed an apparently fresh exit hole over one of them. 

 I visited the greenhouse the following morning and tried to 

 trace up all receipts of Persea seeds from which weevils might 

 have issued. It seems only one lot was infested. This was 

 received from a dealer in San Jose, Costa Rica, December 

 26, 1911, consisting of 26 seeds of Persea pittieri, which were 

 then noted as being in poor condition. Five of these seeds had 

 germinated and grown to plants from a foot to a foot and a 

 half in height, and from the cotyledons of three of these plants 

 weevils had issued, leaving a still very obvious exit hole in 

 the soil close to the plant stem. These three plants were taken 

 up and the cotyledons showed the same injury that had ap- 

 peared from the other seeds, but, of course, this injury had 

 not affected the germ. On May 23, four additional plants that 

 had been grown at Miami, Florida, from seeds of the same 

 lot were examined and the cotyledons showed no exit holes. 



A plant grown in the local greenhouse which when examined 

 three weeks earlier had shown no sign of infestation, now had 

 an apparently fresh exit hole in the soil about an inch from the 

 stem, which led down into the pupal chamber in the coty- 

 ledon. This plant seemed less robust in its growth than the 

 others. Another adult, dismembered by ants, was found on a 

 ledge in the greenhouse, but may have been there for weeks. 



A specimen of this weevil was taken early in July at Whit- 

 tier, California, in a grove of avocados about 2 years old, in the 

 nursery of Mr. Hideout. Mr. P. H. Dorset, of the Bureau 

 of Plant Industry, who found the weevil, believes it came from 

 Mexican seed, but states that no seed had been planted in 

 that part of the nursery for nearly a year. 



Seven adults, two pupse, and a larva of this species are now 

 in the National collection. Of the adults the four that issued 

 in the Washington greenhouse from the seed of Persea pit- 

 tieri from Costa Rica are of a decided red ground-color, with 

 red femora, and lack the two transverse white fascia of the 

 elytra, while the other three are dark brown, have unicolor- 

 ous legs, and display the prominent patches of white scales 

 mentioned and figured in the Biologia Centrali- Americana.
