time wet and windy, they seldom flew out with beating ; and as I took them for 

 nothing else but our common quercifoliella, so I gave myself less trouble about them 

 than I should have otherwise done. It probably occurs in other parts of the South of 

 Europe, on the same species of oak.'' 



This species exists in most collections in this country, mixed with the next species, 

 under the name of Harrisella ; and as Haworth has described quercifoliella as Har- 

 risella var. /3., the question arises — is this insect his typical Harrisella ? but there we 

 can get no information, his description being merely a copy of Linnaeus's, which is so 

 extremely vague that any one of this section of the genus would answer it equally well : 

 — " Wings gold and silver varied, with the apex obtuse, not pointed like the preceding 

 (Clerckella) ; in the apex the colour is ustulated, brownish, with a subocellated black 

 spot." ! ! I am inclined to fancy this species has been overlooked on the Continent, as 

 in this countiy, for it would be strange indeed that an insect should occur both in 

 England and Sicily, and in no intermediate country.

Expansion of the wings 3| — 4| lines. Head tawny. Forehead white. Palpi 

 white. Antennae white, annulated with fuscous. Thorax pale tawny. Abdomen fus- 

 cous, with the extremity fulvous. Legs shining whitish. Tarsi white, with a brown 

 spot at the end of the joints. Anterior wings pale tawny, shining, with a long, nar- 

 row, pale basal line to beyond the middle of the wing : on the costa are four pale spots, 

 on the inner margin three : the first costal spot is slightly curved, and bordered with 

 brown on both sides ; the second is straight; the third and fourth comma-shaped (these 

 are only margined inwardly with brown : the first inner marginal spot is small, curved, 

 and terminates before the end of the basal streak; the second is nearly straight, and 

 terminates between the second and third costal spots ; the third is very indistinct, and 

 has rather a tendency to meet the third costal one : these spots are all margined in- 

 ternally with brown. In some specimens there is a pale mark on the inner margin 

 near the base. At the apex is a round black spot : cilia tawny between the third and 

 fourth costal spots, and just beyond the fourth ; the remainder glossy pale fuscous, 

 with a black arch round the apex of the wing from the fourth costal spot to the third 

 inner marginal spot. Posterior wings clear gray ; cilia grayish fulvous. 



A very common species, frequenting oaks. 



Zeller says of it, " This species is found near Reichstadt, in Bohemia, near Bres- 

 lau and Glogau. Here (Stettin) it is one of the commonest Lithocolletes in oak woods, 

 and flies at the end of April and in May, and again in July and August. It appears 

 nearly the earliest in the genus : on the 14th of April, 1833, I beat a fresh specimen, 

 along with Plutella fissella, out of the dried leaves of a low oak. The caterpillar 

 lives in oak leaves, and Mann has bred them from the same leaf with abrasella and 

 ilicifoliella." 



This species is well described by Haworth, thus: " Anterior wings golden, with a
