VIII. — On three extremely interesting new Moths of the Family 

 Chalcosiidas from Kilima-njaro and Natal. By ARTHUR 

 G. Butler/F.L.S., F.Z.S., &c. 



Two of tlie following species were collected by Mr. F. J, 

 Jackson near Kilima-njaro and were presented bj him to the 

 Museum. 



It will be remembered that in the ' Annals ' for 1884 I 

 described a remarkable genus of moths under the name of 

 Pedoptila ; that in 1885 1 referred to the allied genus Dora- 

 topteryx of Rogenhofer, and pointed out how it ditiered from 

 Pedoptila ; and, lastly, in 1887 I described a third genus 

 of the same group under the name of Semiojytila^ all three 

 genera being African. 



Mr. Jackson has now brought to light a second species of 

 Doratopteryx ; and although every specimen has unfortu- 

 nately arrived in a more or less broken condition, I am now 

 in a position to point out certain inaccuracies which occur in 

 Herr Rogenhofer's description of the genus. 



The species figured and described by Herr Rogenhofer 

 proves to be a female, not a male as he supposed j the males 

 have distinctly pectinated antenua3. 



The secondaries certainly have two veins as stated, but 

 they have more than that ; the subcostal vein passes down 

 the tail ; at the third fourth of its length the tail expands, and 

 here the subcostal vein throws off a branch which terminates 

 near the end of the expanded portion^ whilst the main vein 

 continues on to the point of the tail ; the niedian vein, which 

 is double, emits a short branch just before the tail, and ter-
