* The following closely allied species occurs on the coast in the same latitude :— Systates beiranus, sp. n.— Closely resembling S. exaptus in form and colouring, but smaller and differing in the following particulars : rostrum with the dorsal area slightly convex longitudinally in the basal half, the anterior impressed portion not triangular, but separated off by a low transverse ridge ; no longitudinal ridge behind the scrobe ; the epistome slightly asymmetrical, the apex of the curve formed by the delimiting carina being a little to the left of the median line, and the carina on the right side rather longer and higher than that on the left ; the prothorax with a very low median costa in the anterior half ; the hind tibiae of ♂ smooth and flattened internally, but less incurved at the apex and without any tooth on the lower edge ; the elytra vertically truncate at the base ; 1st ventrite without tubercles in ♂. Length, 5–6 mm. ; breadth, 2.4–3 mm. PORTUGUESE EAST AFRICA : Beria, x.1900—x.1904 (P. A. Sheppard) ; 3♂ ♂, 7 ♀ ♀.

* Schönherr records this species from Bengal, but his description agrees well with a South African species. Prof. Aurivillius has kindly confirmed the identification on comparing one of my African specimens with the type of C. sculpturata, which, he informs me, bears the label “Cap. B. spei Drége.” The Indian record seems almost certainly erroneous. Drége resided in South Africa, and all the other species described from his collection by Schönherr are from that country.
