distinct, and exserted. The antenne are rather short, without any hook at the tip, and terminated by a gradually- 
formed arched club; the head is rather broad, with a tuft of recurved hair at the base of the antenne, and the 
thorax robust. The wings are short, and rounded along the outer margin, in both sexes ; the front margin towards 
the base in the males being folded, the base rounded : the mediastinal vein scarcely extends beyond the middle 
of the front margin of the wing; the postcostal one extends to a short distance below the apex of the wing, 
emitting on its front side four straight branches, the fourth of which runs to the tip of the wing; it also emits a 
branch from its posterior side. The great median vein is divided into three branches, and between the anterior

by having a thickened, oblique patch upon the disc of the fore wings. The wings in repose are deflewed. 
abdomen in the males is narrow, with the tip bearded, whilst.in the females it is more robust, with the tip acute 
and nearly naked. The cilia of the wings is long, alternately black and white, and the wings are also of a dark 
colour, spotted with white. 
The larve are naked, or but very slightly pubescent, resembling those of the Tortricidee, with a large head, 
the following segment being attenuated; generally subsisting upon the rolled up leaves of malvaceous plants. 
The pupa is entire and conical in its form, inclosed in a cocoon, and fastened by the tail as well as by a girth 
round the middle. 
As there are a considerable number of species agreeing with Malve, I have retained that as the type of a 
distinct genus, for which I have employed Hiibner’s name in preference to that of Thymele or Fabricius (used by 
Stephens), the real types of which are exotic-tailed species, and because it has a priority of date over that of 
Syrichtus of Boisduval, employed for the group.

This species generally measures about an inch in the expanse of the wings, varying a little both more or less. 
On the upper side the wings are of a dark brown colour, marked with many small, squarish, cream-coloured 
spots, of which there are about fourteen on each of the fore wings; the ground colour of which, especially towards 
the base, is much powdered with white, especially in the males. 
several more or less confluent larger spots, and beyond the centre is a curved row of six small dots.
