THE MACRO-LEPIDOPTERA OF COUNTY TYRONE. SI 
and Mr. Hugh Scott for assistance when studying this fly. As 
close a comparison as I was able to make showed no important 
difference from the modern genus Scholastes, Lw., 1873. Super- 
ficially the fly is perhaps rather more like the species of 
Euprosopia, but the submarginal cell, contracted before the end, 
agrees better with Scholastes. The existing forms of Scholastes 
are smaller. The question has arisen whether these pieces 
of amber are genuinely British. There are two alternative 
possibilities : 
(1) That the specimens are ‘‘faked’’ for sale. After careful 
consideration I am sure this must be considered out of the question, 
as all contain minute insects or spiders, which surely would not 
have been put in by an artificer. 
(2) That the specimens are in copal from Africa, being either 
imported and sold as native amber, or possibly derived from the 
wreck of a ship. The material looks very much like copal, but 
the two honey-bees are too large for the African Apis unicolor, 
Latr., which they should presumably be if in copal. They can 
only be referred to A. mellifera, the black variety with slightly 
pallid scutellum. 
Assuming that the amber is genuinely British, we can 
say definitely that it is not contemporaneous with the Baltie 
(Oligocene) amber. All the bees in Baltic amber seen by me 
belong to extinct genera, and this amber nearly always contains 
trichomes of the oak, absent from the Yarmouth material. The 
Ortalid now described is of an Ethiopian or Oriental type, but I 
cannot identify it with any species in the British Museum. African 
copal may be Pleistoecne or recent, and the older copal probably 
contains at least some extinct species. The fly, so far as it goes, 
distinctly suggests that the material may be copal, but it might 
very well occur in Britain in amber of upper tertiary age, say 
Pliocene. The question is a very interesting one, and it is to 
be hoped that further and more definite evidence will be found. 
Miocene amber is known from other parts of Europe.
