318 Mr. M. Jacoby's contributions to the knowledge of 
cavities in common with this genus. The structure of 
the antennae, quite different in the sexes, and the almost 
punctate-striate and costate elytra justify the creation of 
a new genus for this species. 
Haltica semiaurataj sp. n. 
Obscurely fulvous, the elytra with a slight metallic-golden lustre, 
thorax impunctate, the basal sulcus straight ; elytra very closely 
and finely punctured, with traces of longitudinal sulcations. 
Length, 2 lines. 
Head dark fulvous, impunctate, very deeply transversely 
grooved between the eyes, the frontal tubercles broad, ill- defined, 
the carina strongly raised ; antennae fulvous, extending to the 
middle of the elytra, the third joint very slightly longer than the 
fourth ; thorax scarcely twice as broad as long, the lateral margins 
straight, the anterior angles oblique, the posterior ones acute, the 
surface without punctures, obscurely fulvous, the base with a narrow 
and straight transverse sulcus ; scutellum broad, its apex rounded; 
elytra dark fulvous, finely and closely punctured, clothed with 
extremely short golden pubescence, giving it a slight metallic 
appearance, the disc with some obsolete longitudinal grooves ; 
underside and legs fulvous, the last abdominal segment roundly 
produced at the middle, with a central longitudinal groove. 
Hah. Natal, Maritzburg. 
The coloration of this species is peculiar and unique, 
as far as I know, amongst the representatives of the 
genus, which are nearly all of a metallic-blue colour. 
The present insect gives the impression of being imma- 
ture, but the two specimens I have before me agree 
entirely in every particular, and their elytra are of hard 
texture ; these are fulvous, but appear quite golden in 
certain lights. 
Haltica cuprea, sp. n. 
Bluish-black, above reddish-cupreous ; thorax very closely and 
finely punctured, the basal sulcus distinct and straight ; elytra as 
closely but more strongly punctured than the thorax. Length, 1^ 
lines. 
Head impunctate at the vertex, obliquely grooved between the 
eyes, the latter with some deep punctures near the inner margins, 
frontal tubercles broad, rather round, carina broad, with a longi- 
tudinal groove, clypeus greenish^ palpi black ; antennae extending 
to about the middle of the elytra, black, the lower joints with a 
bluish gloss, third and fourth joints equal ; thorax twice as broad
