TYPES OF LEPIDOPTERA. 
48. Gelechia improbella is a species of the genus Lulechria. I 
have not been able to identify it with any of Mr. 
Meyrick’s descriptions, but it is a species difficult to 
recognise. I describe it below. 
49. Gelechia gemmipunctella is represented by a single fore 
wing only, but this is sufficient to identify it with 
Glyphipteryx atristiella, Zel. I consider G.  chry- 
solithella, Meyr., to be the same species, the colour of 
the hind wings being variable in different localities. 
50. Oecophora impletella. The type is missing, but from 
the description I have no hesitation in identifying 
this with Philobota herodiella, Feld. As vol. u. ot 
the Reise Novara was published in 1874, Walker's 
name has the priority. 
51. Cryptolechia scitipunctella is a synonym of Hoplitica 
repandula, Zel. 
In the National Museum is the Curtis collection of British insects. 
Among them I examined Arcturus sparshallii, Curt., which is un- 
doubtedly the same as Trichetra stibosma, Butl. Mr. Lyell informs 
me that he considers this to be a varietal form of Trichetra melanosoma, 
Wlk. How this Australian insect came to be ascribed to Great 
Britain must remain a mystery. 
In the Museum Library I had an opportunity of examining 
Donovan’s Insects of New Holland. His Tinea strigatella (Plate 40) 
is the same as Philobota chrysopotama, Meyr. The only discrepancy 
is that the ground-colour is figured purple, but comparison with the 
description shows that this is an error of the colourist.
