536 Lord Walsingham’s catalogue of the Pterophoride, 
Mrs. Wollaston’s collections from St. Helena (also in 
the British Museum), of which descriptions were pub- 
lished by herself and the late Francis Walker [Walker, 
F., in Meliss’ Saint Helena; London, 1875. Wollaston, 
Mrs. T. V., “Notes on the Lepidoptera of St. Helena, 
with Descriptions of New Species,” Ann. and Mag., 
N.H. (5 s.), 111.; London, 1879: this was republished in 
pamphlet form], are also important contributions to the 
study of the subject as connected with these groups of 
Atlantic islands which he nearest to the African coast. 
The present paper shows that the genus Blastobasis 
and its allies are more than proportionately represented 
in the Madeiras, and the line of their distribution over 
the European and American continents is thus connected 
and emphasized. The genera represented are, for the 
most part, common to both Kurope and America, but the 
majority cf the species recugnized are Kuropean. One 
notable exception may be found in Cosmopteryx pul- 
cherrimella, Chamb., hitherto recorded only from the 
United States, this has been very carefully compared 
with American specimens in my collection. 
I have only to express my thanks to Mr. Bethune- 
Baker for kindly supplying me with so much interesting 
material, by which he has reinspired me with the hope 
of some day making a more complete and representative 
collection either personally or by deputy, in the Madeiran 
group of islands which I have long been anxious to 
visit. 
By the list given it will be seen that sixty-six species 
of micro-lepidoptera are now known to occur in the 
Madeiras (four are not described); of these, thirty are 
peculiar to these islands, twelve are common to the 
Madeiras and Canaries (of which two do not occur else- 
where), and one extends its range only to North Africa. 
One species is peculiar to the Madeiras and to the United 
States. Thiuty-two species occur in Europe, and of 
these, nine extend to the Canaries, thirteen to North 
America, and four to North Africa. 
Over thirty species are added to the list, one new genus, 
seven new species, and two new varieties being here 
described.
