frontal plate highly polished. Body eylindriealf and tapering a little towards the 

 extremities : there is a slight transverse depression on each segment, and these, to- 

 gether with the deeply cut segmental divisions, give the skin a wrinkled appearance. 

 Tubercles very large and prominent, and are, as well as the whole surface of the 

 body, rather glossy, though not so much so as the head and frontal plate. 



The ground-colour varies in different specimens from dull purplish-brown, to an 

 equally dingy greyish-green, but the purple-tinted forms predominate ; head very 

 dark sienna-brown, the depth of colour varying in different specimens ; frontal plate 

 paler, and partaking more of the colouring of the dorsal surface ; the dark pulsating 

 alimentary canal forms the dorsal line, but there are no perceptible sub-dorsal or 

 spiracular lines. The large tubercles correspond to the ground-colour, but are much 

 darker in tint ; spiracles very small, black. 



Ventral surface and pro-legs of the ground-colour of the dorsal area, but the 

 legs, until towards the base, very dark sienna-brown.

DESCRIPTIONS OF NEW SPECIES OP RETEROCEEA. 

 BY HERBERT DRUCE, F.L.S., F.Z.S. 



The following descriptions are all from specimens in my own 

 possession. The collection lately sent home by Mrs. Monteiro con- 

 tained, besides those that I have described as new, several interesting 

 species, such as Darapsa rosce, Saturnia JVallengreni, &c. 



Family AGAEISTID^. 



^GOCEEA AFPINIS, Sp. U. 



Primaries the same as ^.fervida, Walker, excepting that the costal margin is 

 broadly wliite nearly to the apex, and the fringe white instead of yellow. Second- 

 aries pale chrome-yellow, the apex broadly bordered with reddish-brown, head and 

 thorax reddish-brown, abdomen yellow. Expanse, If inch. 



Sab. : Mauboia, East Central Africa (Last). 



A very distinct species, easily separated from ^. Jervida, "Walker, 



^GOCERA TRICOLOR, Sp. tl. 



Primaries black, thickly speckled with greyish scales, a large, cream-coloured, 

 oval-shaped band beyond the middle, extending from the costal margin to the anal 

 angle, a cream-coloured stripe from the base to the middle of the wing, parallel with 

 the inner margin, both the pale markings bordered with a narrow black line, and on 

 the outer margins by faint metallic lines. Under-side orange, with the costal, outer 

 and inner margins, also a central band, all black, a small black dot at the end of the 

 cell. Secondaries deep chrome-yellow, with a broad marginal black band, the fringe 

 white. Head and antennae black, thorax black, striped with grey and yellow bands. 

 Abdomen black, the sides deep chrome-yellow. Expanse, 2i inch. 



Sab. : East Africa {31rs. Monteiro). 



This fine insect is allied to j^. Trimenii, Felder, but it is very 

 distinct.
