the wings, with Clerome, in which latter respect also it differs from 

 Drusilla. The fact however of its being entirely destitute of 

 ocelli is perhaps of sufficient importance to warrant its sub-generic 

 separation, in which case it may receive the name of Melanocyma. 

 Mr. Hewitson having represented the upper surface of the insect 

 on plate 54 of the " Genera of Diurnal Lepidoptera," the far more 

 striking under surface is here only figured. The second branch of 

 the post-costal vein of the fore wings, arises at about three-fourths 

 of the length of the wings from the base opposite to the junction of 

 the costal vein with the costa, and the fourth branch opposite to the 

 junction of the extremity of the first branch with the costa. The 

 lower disco-cellular vein closing the discoidal cell is singularly 

 angulated, and the costal vein of the hind wings only extends to 

 the middle of the costal margin. Another peculiarity of the 

 species consists in the slight clothing of the wings, which enables 

 the black undulated markings of the under surface to be partially 

 seen from above. 



The upper side of the fore wings is a pale brown, the lower 

 ones being buff", with the inner half of a rich fulvous colour. 

 Beneath the fore wings are still paler, being of a dirty white, the 

 inner half of the hind wings more richly fulvous, the" black bars 

 form four irregular fasciae independently of the submarginal line, 

 which is dilated in the middle of the hind wings. The specimen 

 in Mr. Wallace's collection which I have examined is a female.

 In the shortness and roun Iness of the fore wings, and in the upper 

 surface being destitute of ocelli, this insect agrees with the genus 

 Clerome, but differs in the broad oblique yellow fascia and subapical 

 white spot of the fore wings, as well as the more elongated form 

 of the hind wings and the insertion of the second branch of the 

 subcostal vein at a short distance beyond the extremity of the 

 discoidal cell, (opposite to the extremity of the costal vein, which 

 only reaches to the middle of the costa,) the third and fourth 

 branches of the post-costal vein of the fore wings rise a moderate
