Front-wings traversed beyond the middle by a series of six small 

 blue spots, the third to fifth lunular, the others sub-ovate ; a sub-costal 

 spot of the same colour between them and the apex. 



Hind-wings with an oblique discal series of seven blue spots, 

 tapering from the apex to the anal angle ; eight sub-marginal white 

 points delicately encircled by blue scales and seven linear marginal 

 striae; abdominal margin and body brown, coarsely clothed with hair. 



Wings below silky olivaceous, the apical area inclining to ochraceous, 

 and sharply defined by a curved line running from the anal angle of 

 the hind- to the apex of the front- wings ; the basal area crossed by two 

 irregular silvery bands, terminating in the front-wings in two ochraceous 

 spots ; the interior band limited outwardly, and the exterior one inwardly, 

 by a black and white line. 



Front-wings with a pale undulated line upon apical area, two black 

 ocellate spots with white irides near the base, and a black stria at the 

 end of the cell. 



Hind-wings with a large sub-anal silver patch and eight white sub- 

 marginal spots, the three nearest the anal angle pupillated with black ; 

 body brown, the centre of the thorax, palpi, tibiae, and tarsi ochraceous. 

 Expanse of wings 3i inches. 



Inhabits "West Africa (Ashanti ?) . 



This beautiful species, which I hope shortly to be able to figure, is 

 allied to Tiridates and Mycerina, the coloration of the upper surface 

 being somewhat similar to the former, the shape of the wings and 

 underside colouring more nearly approaching the latter species.

NOTE ON THE CECONOMY OP NEMATUS SALICETI, FALLEN. 

 BY ALBEET MTTLLEB. 



In the beginning of August, 1868, 1 collected in this neighbourhood 

 a quantity of the common elongated spongy galls, belonging to this 

 species. They occurred on a willow (Salix fragilis ?), on which it 

 would have been difficult to point out a leaf not beset with two or 

 more specimens ; in fact, many leaves were crowded to excess, and 

 presented the appearance of two rows of red rugose beans, but the 

 midrib of the leaves was free throughout. 



The larvae were full-fed about the 8th of August. Unlike other 

 gall-feeders of the genus, they had not eaten the galls to a clean thin 

 shell, but left a rather thick fleshy covering intact, through which they 

 gnawed a round hole and dropped to the ground, leaving their late
