 BY W. L. DISTANT. 



EEDUVIID^. 



Centraspis impeeialis, "Westw. 

 Var. BicoLOR, Dist. 



Black, shiuiug, fore lobe of pronotum dull red ; fiftli joint of 

 antennae slightly longer than tlie fourth, and considerably longer tban 

 tbe sixth, last four joints fulvous ; rostrum black, aj^ical joints reddish. 

 Pronotum with a central longitudinal furrow extending through the 

 fore lobe to near the posterior margin of the hind lobe, a rounded and 

 deeply excavated impression on each side at the junction of fore and 

 hind lobes, and a smaller one near each lateral angle, situated on the 

 hind margin. Scutellum reddish, with a rounded central impression. 

 Elytra black, opaque. Abdominal border with a row of sub-quadrate 

 reddish-yellow spots. Abdomen below shining black, with four 

 reddish-yellow fasciae, situated on the centre of the second, third, 

 fourth, and fifth segments, not extending to the abdominal border. 

 Legs black, tarsi reddish, 



J. Antennae setose, second joint about twice the length of the 

 first. Ante-ocular part of the head compressed, channelled. Hind 

 lobe of pronotum nearly twice as long as the fore lobe, disc of hind 

 lobe elevated and rounded. Elytra almost reaching the apex of the 

 abdomen. 



Long. 35 mill. Greatest lat., 12 mill. 



? . Antennae slightly setose, second joint not twice the length of 

 the first, head broad, raised, very slightly channelled. Hind lobe of 

 pronotum a little longer than fore lobe, with the disc slightly raised. 

 Elytra not nearly reaching apex of abdomen. 



Long. 37 mill. Greatest lat., 1-1 mill. 



Hab. : Camaroons (Rutherford), Mongo-ma-lobah. 



It is probable that this may be a distinct species, the bi-coloration 

 of the pronotum, and the totally different coloration of the under-side 

 at once differentiate it from " G. imperialist I have, however, as the 

 result of a careful examination of one specimen of C. imperialis in 

 the British Museum, been unable to discover any sufiicient structural 

 character to separate it from that species. That specimen has the 

 last three joints of the antennae as described above, which character 

 does not sufficiently appear in AVestwood's figure : Trans. Ent. Soc. iv, 

 pi. 7, fig. 2 (1847). •
