The smaller and narrower size of the insect, and especially the form of the yellow spot on the pygidium (fig. 
54), and the rich chestnut coloured stripe on each elytron, well distinguish this species from its immediate allies. 
The mentum is light chestnut coloured; it is much angulated in the middle ; the apical portion (fig. 5a, head 
seen in front, concealing the basal portion of the mentum) being broadly cordate, the front margin being but 
slightly emarginate. The middle of the thorax, in front of the scutellum, is but slightly impressed.

This species is at once distinguished by the deeply emarginated hind margin of the prothorax. The man- 
dibles have the outer blade considerably elongated (fig. 11 a). The maxille have the upper lobe forming a very 
acute sickle-shaped tooth, and the lower lobe is acutely bidentate with several spinulose sete on the inner 
margin (fig. 114). The mentum is oblong, with the apical half oblique and the apex nearly truncate (fig. 
lle, 11d, the same seen sideways). The mesosternum is broad, rather rounded in front, obtuse (fig. 11/), 
and but slightly porrected (11 e, seen sideways). The anterior tarsi are 5-jointed, but the basal joint is con- 
cealed above by the produced extremity of the tibia. The punctures on the dise of the elytra form transverse 
curved lines, and they are very crowded together at the sides, the apex being marked with oblique striole. 
The pygidium is black, longitudinally carinated down the middle with two oval convex yellow spots, striolated 
at the sides, the striole in the middle being transversely curved. The abdomen beneath is black and glossy ; 
it is convex, the second and third segments with a very slight longitudinal impression in the middle. The 
metasternum is marked with a large nearly cireular spot of yellow on each side (visible from above), and the 
third and fourth segments have a yellow spot on each side also seen from above. The terminal pair of spiracles 
of the abdomen are conically elevated. 
The specimen figured in the plate was kindly forwarded to me by M. Boheman from Stockholm, where 
I have also since examined other individuals. 
Species 7 (9)—MACROMA LUTESCENS. 
Puate VII, Fie. 2. 
Oblonga subdepressa, luteo-fulva, nitida, capite et pronoto levibus; elytris sublevibus; vertice inter oculos 
litura V tenui notato, lateribusque pone oculos castaneis; pronoto postice in medio sulcato, luteo-fulvo, vittis 
duabus latis longitudinalibus antice angustatis, castaneis, punctisque duobus antico-lateralibus nigris ; elytris 
ad suturam depressis, puncto humerali maculisque duabus irregularibus subapicalibus castaneis ; margine 
tenuissimo postico pronoti et. sutura tenuissima nigris; pedibus brevibus castaneo-rufis, femoribus supra fulvis ; 
abdomine subtus fulvo flavoque variegato. 
Long. corp. lin. 10. 
Habitat ; Port Natal. In Mus. Britann. 
The clypeus is oval and entire in front ; the prothorax is subtriangular, with the posterior angles rounded ; 
the abdomen above is chestnut coloured, the terminal joint having a transverse yellow fascia with a small 
conical apical spot of chestnut.
