uniformly coatod w'ìih \)o\m]ct is that by MacLachlaii 

 (Jüuni. Unii. Soc. J.oikIoh, Vol. XVI, 1882, pp. ijS- 

 174) of Seniidaiis pulchcUa, Avhere he says that certain 

 spots on the wing had the powder less dense. I have 

 been able lo examine MacLachlan's type and find that 

 this is not correct. The win;jf is fairly evenly coaled with 

 \\hilc powder, as usual, but the wing membrane

being pigmented black only in certain spots gives the 

 appearance of greyer and less densely covered patches. 

 As MacLachlan gives no figure, and his collection is 

 not easy of access, a reproduction of a rough free- 

 hand sl<etcli made of the wings is given 'n Figure 9. 

 This figure cannot be depended upon for some vena- 

 lional details, and it was not made with a camera 

 lucida. Its only value is in shewing the distribution 

 of blackish spots. The venation appears to be typical 

 of Scmidalis Enderl.
