MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 105 



Family Oinophilidae 



Genus Oinophila Stephens 



Oinophila v-flava (Haworth) 



Gracillaria v-flava Haworth, 1811, Lepidoptera Britannica, pt. 4, p. 530. 



Distribution: Masatierra: Bahia Cumberland, 4cfcf, 4 99 (Feb. 

 17, 1951 to Mar. 13, 1955); La Mona, 400 m., d", 9 (Feb. 16, 1951). 



Usually the larva of this species is recorded in Europe as feeding 

 on fungi in cellars and on molds on the corks of wine bottles. There 

 is one specimen in this present collection marked "Grutas de las 

 Patriotas" which suggests conformation with European habits of 

 this insect but in Western United States the species has been re- 

 corded from Baccharis. 



Tinea pellionella Linnaeus 



Phalaena Tinea pellionella Linnaeus, 1758, Systema naturae, ed. 10, 536. 



Distribution: Masatierra: Bahia Cumberland, cT (Feb. 3, 1952). 

 Masafuera: Quebrada de las Casas, cf (Jan. 16, 1952). 



In recording this species I do so with some misgivings. Although 

 we should expect to find pellionella in these islands, along with species 

 with similar habits, these specimens are not exact matches for what 

 we generally consider to be normal pellionella. On the other hand, 

 the series at the U.S. National Museum and at the British Museum, 

 show considerable variation for this variable species. Certainly 

 the two examples before me do not approach in character any other 

 known form and they do not warrant description as a distinct taxon. 



Family Lyonetiidae 



Genus Bedellia Stainton 



Bedellia somnulentella (Zeller) 



Lyonetia somnulentella Zeller, 1847, Isis von Oken, vol. 12, p. 894. 



Distribution: Masatierra: Bahia Cumberland, 6c?'cf^, 4 99 (Jan. 

 7 to Mar. 14, 1951-1955). Masafuera: Quebrada de las Vacas, 9 

 (Jan. 17, 1952). 



This common and widespread pest of sweet potato and other 

 allied plants is another of the species carried and distributed through 

 commerce. Its presence in the Juan Fernandez Islands was to be 

 expected.
