26 Mr. R. M‘Lachlan on some 
Head black above, but with broad ochreous anterior margin ; 
narrow orbital margins of the same colour, and varied with 
ochreous about the ocelli (or the colour might be taken as 
ochreous, with a very broad transverse black band) ; clypeus 
broadly margined with black; labrum dark brown; labium 
and back of head pale yellow. Prothorax yellow, with two 
median blackish lines and a brown band above the insertion 
of the legs; posterior margin elevated and blackish in the 
middle. Thorax ochreous; above with a bronzy-black (or 
bronzy-green) band on either side of the dorsal crest; its 
external edge at first straight, then very deeply excised in the 
middle (a golden-yellow oblong spot in the excision), so that 
its breadth is reduced to a fine line, afterwards dilated poste- 
riorly in a triangular manner, the rounded apex of the dilata- 
tion not touching the mesothoracic suture; below these 
bands are vestiges of a like-coloured posthumeral band, 
reduced to two isolated spots (the inferior of which 1s oblique) 
connected by a brown line; still more inferiorly are four or 
five black spots on the median and metathoracic areas, which, 
and also the pectus, are whitish pruinose. Legs pale yellow ; 
femora with two fine black lines ; tibize black externally, tarsi 
and spines black. Abdomen very slender, above dark bronzy 
green, changing to bronzy brown after the third segment ; 
posterior half of the ninth segment and the whole of the tenth 
yellowish (probably pruinose in life), with black edges ; on the 
first segment are two dark green spots, divided by a yellow 
median line ; second with a median line, an excision on either 
side, and the suture yellow; third to fifth yellowish at the 
anterior suture ; sides and beneath yellow, with black spots 
on the first and second segments, and a blackish ring (complete 
ventrally) at the end of segments 1 to 5. 
3. There are minute black teeth on the posterior margin 
of the ninth segment above; tenth segment with a broad 
triangular median excision, with small black teeth on the 
edge of it. Superior appendages slightly longer than the 
tenth segment, black, strong, the apices regularly but some- 
what suddenly incurved (not geniculate) ; externally with 
four or five rather strong denticulations on the apical portion ; 
on the internal edge there is a very strong triangular black 
tooth, rather distant from the base, after which the edge is 
straight for some distance, and also there is a smaller acute 
tooth, followed immediately by a large subquadrate blunt 
tooth before the commencement of the short slender inturned 
apical portion of the appendage. Inferior appendages about 
half the length of the superior; viewed from above they are 
dilated at the base, incurved, gradually becoming more
