jOQ BRITISH BUTTERFLIES 



distinct, and cxscrtcd. The antennw are rather sliort, without any hook at the tip, and terminated hy a gradually- 

 formed arched chib ; tlie head is rather l>road, witli a tuft of recurved hair at the base of the antcnnw, and the 

 thorax robust. The wiuos 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 mar<dn of the wing; the postcostal one extends to a short distance below the apex of the wing, 

 eniittino- 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 

 one of these and the posterior one of the postcostal vein, is a straight free vein*. The males arc not distinguished 

 by havino- a thickened, oblique patch upon the disc of the fore wings. The wings in repose are ilffcnd. The 

 abdomen in the males is narrow, with the tip bearded, wliilst in the females it is more robust, with the tip acute 

 and nearly naked. The cilia of the wings is long, a,lternately black and white, and the wings are also of a dark 

 colour, spotted with white. 



The larvaj are naked, or but very slightly pubescent, resembling those of the Tortricidse, 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 JIalvaj, 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 gi'onp.

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. The middle of the hind vv-ings is marked with 

 several more or loss confluent larger spots, and beyond the centre is a curved row of six small dots. The cilia is 

 white, spotted alternately with black ; the body has a greenish hue. Beneath, the ground colour of the wings is 

 much paler, the spots towards the tips of the wings forming fine lines ; the spots are also larger and more 



* I bavc found no material vaiiation in regard to the arrangeuitnt of the veins of tlie wings, in any of the indigenous species of tlic entire 

 family.
