&. The type was a teneral‘ individual. The other males are older and show the colour-changes accompanying 
age as follows :—The brown on the superior surface of the frons becomes darker and the metallic-blue 
reflection more strongly marked. The pale colours (yellow) of the thorax and abdomen, except on the 
terminal appendages, change to a greenish-blue, the change being manifest on the thorax and segments 
1-4, before it is well-marked on 5-7 (Bebedero 3). The reddish-brown and brown of the thorax and 
abdomen become blackish. The “hollow oblong”? of reddish-brown on the thoracic dorsum fills up with 
irregular brown markings, later darkening, until the dorsum is almost entirely blackish-brown (except 
for a bluish or greenish line along each side of the mid-dorsal carina), but not so far back on each side 
as the humeral suture, although a narrow obliquely and downwardly directed prolongation extends from 
about mid-height of the blackish-brown to the dark line on the humeral suture. There are isolated 
blackish spots on the site of the obsolete first lateral thoracic suture, above the metastigma; they are 
present in the teneral type as pale reddish-brown spots of the same shape as in the adult. 
Q (hitherto undescribed). Colours very similar to those of the male and apparently passing through the same 
age-changes, but I have seen no individual in which the almost solid blackish-brown thoracic dorsum is 
reached, as in the males described above. In this sex the superior surface of the frons sometimes has the 
brown spot and metallic-blue reflection as described for the male, this variation seeming to be independent 
of age. Apical margin of vulvar lamina entire, reaching to one-third the length of segment 9. 
Abdominal appendages pale yellowish, brown at extreme base and tip. 
3 Q. Front wings with 9-11 ante-, 8-10 postcubitals ; hind wings with 7-9 ante-, 8-11 postcubitals.

Dr. F. Ris has examined the type of A. theresiew, Selys?, in the possession of Her 
Royal Highness the Princess Theresa of Bavaria, and writes (6, xii. 05): “ I cannot see 
in this type any other thing than a small female of A. guttata.” See also the remarks 
at the end of A. guttata, infra.
