ON NEW AND LITTLE-KNOWN LEPIDOPTERA. 191 



base to about the middle of the submedian interspace, and a slightly 

 longer similar one in the sutural area. Hindwing with a large chrome- 

 yellow patch in the middle of the disc ; the base with long chrome- 

 yellow setae. Cilia of the hindwing almost entirely chrome-yellow, of 

 the fore wing chrome-yellow of a duller shade mixed with black. 

 Underside, for-ewing black i a costal chrome-yellow streak, which is 

 joined to a wide similar streak occupying the outer two-thirds of the 

 cell, both joined to the anterior discal patch of the upperside ; the 

 lower discal patch as on the upperside, but composed of two portions 

 only, with no third minute portion in the submedian interspace ; the 

 apex of the wing more or less chrome-yellow ; a fine anteciliary 

 chrome-yellow line. Hindioing chrome-yellow, with numerous small 

 black spots scattered evenly over the surface ; a fine black anteciliary 

 thread. Antennm above black, beneath chrome-yellow. Thorax and 

 abdomen above black, beneath and legs chrome-yellow. 



Very near to Ampittia maro, Fabricius = Cyclopides camertes, 

 Hewitson = Thymelicus palemonides, Snellen,* from Indian and Cey- 

 lonese specimens of which of the same sex it differs on both sides of the 

 forewing in lacking the chrome-yellow spot in the middle of the sub- 

 median interspace, and on the underside in the ground-colour of the 

 forewing being much deeper black, and all the spots of the hind win o- 

 being deep black, and consequently much more prominent. The cilia 

 of the hindwing is also almost entirely chrome-yellow, instead of pro- 

 minently spotted with fuscous at the termination of all the veins. It is 

 but distantly allied to Tai'actrocera atropunctata^ Watson, MS. from 

 Upper Burma, the type specimens of which are before me as I write, 

 and which has in the male all the chrome-yellow markings of the 

 upperside very greatly red need in size. In this species the knob to the 

 antennae is large and spatulate with no terminal crook, in A. maro 

 the knob is smaller and elongated with a very small crook, in 

 A. maroides the crook is distinctly longer.
