subsequent to its roavrangement and the incorporation of the 

 Godman and Salvin and other important accessions ; had he 

 done so, it would have been surelj impossible for him to have 

 restored T. Desjardinsii (in liis recent work) to its ancient 

 state of chaos. T. regularis is a species found in Northern, 

 E. Central, and Western Africa, but not occurring below 

 Zanzibar to my knowledge ; it is a wet-season form, without 

 markings on the under surface, and the female has a well- 

 defined border to tlie secondaries. T. Marshnlli is a far more 

 angular-winged insect, occurring rarely on the West Coast 

 (we have only five western examples in a series of fifty-seven) ; 

 it is the prevailing species in the south, and is not very 

 common in the east; it is well marked on the under surface, 

 and the female has a narrow dentated border with the spots 

 often separate, always in the intermediate and dry forms. 

 T. Desjardinsii is an island form having apparently only a 

 dry phase*, the female {T. aliena) with a reddish apical fiush 

 above, but no dark marginal markings. T. punctinotata, the 

 male of which is of a much brighter clearer yellow than any 

 other species of the gi'oup, appears to be an intermediate- 

 season form, inasmuch as it shows no rose-colouring on the 

 under surface in eitlier sex : it may, however, be a dry form 

 of T. regularis, inasmuch as the outer border of the primaries 

 in the male has a similar almost unbroken arch to its inner 

 edge ; if this be the case, it proves still more conclusively the 

 entire specific distinctness of T. regularis from T. Marshalli, 

 the markings on the under surface being very different and 

 much sharper. The female, of course, is unlike that of any 

 otlier form, for I do not believe that T. mandarinulus of 

 Holland is a synonym of it.

The argument used by Prof. Aurivillius for the distinctness 

 of T. hapale from T. floricola might, I think, lose its value if 

 his specimen were soaked in strong spirit. I firmly believe 

 that the male abdomen would then drop off, and an ordinary 

 female would remain. Among the Godman and Salvin 

 examples of T. hapale we received an exactly simih\r female, 

 the abdomen of which is undoubtedly tliat of a male ; the 

 thorax has been rendered shiny and the base of the second- 

 aries stained with weak shellac, proving conclusively that it 



* Even Mabille appears to have known onlj^ the dry form, and 

 fiofures it.
