space equal to two-thirds of their width, and with a very plain, raised 

 orbit continued behind as a shallow groove, anterior groove strongly 

 arcuate ; antennae reaching only to the base of the prothorax, the 

 four basal joints are piceous-red, like the palpi, the six penultimate 

 joints are very strongly serrate inwardly, the last is longer than the 

 one preceding and is somewhat ampliated inwardly ; prothorax 

 distinctly carinate laterally, slightly ampliated and rounded in the 

 centre, a little narrower in front than across the base, which is 

 deeply sulcate, covered on the disk with moderately closely set 

 punctures, which, however, disappear along the lateral keel ; 

 scutellum irnpunctate ; elytra wider than the prothorax, nearly 

 sub-parallel, costate, the costae tectiform with the intervals filled 

 with deep, but small, equally distant punctures ; intermediate and 

 posterior femora clothed underneath with a dense fulvous pubes- 

 cence extending from the base to three-fourths of the length. 



Length 19 mm. ; width 7 mm. 



A very distinct species. 



Hab. Transvaal (Rustenburg). 



STEONGYLIUM EHODESIANUM, n. sp. 



Bluish-green on the upper side, legs and under side dark blue ; 

 belongs to the same group as the preceding species, that is to say, 

 the eyes are divided by a small interval only in the anterior part of 

 the forehead, and the joints of the antennae, especially the fourth, 

 fifth, and sixth are serrate inwardly, the antennae, however, reach 

 only slightly beyond the base of the prothorax ; the latter is some- 

 what narrow, and somewhat ampliate in the middle laterally, not 

 carinate there, and is covered with irregularly scattered, moderately 

 closely set, deep punctures separated by smooth intervals; the elytra 

 are somewhat broader in proportion to the width of the prothorax 

 than either in S. ceratum, S. castaneipcnnc, or S. ovampoense, and moi'e 

 sinuate laterally, they are sharply costate from base to apex, and the 

 narrow intervals are filled with regularly disposed, closely set, small 

 punctures. 



Length 22 mm. ; width 6 mm.

STKOXGYLIUM OVAMPOENSE, n. sp. 



Chestnut-bronze on the upper side, dark blue on the under side,, 

 and with the legs purplish ; head closely punctate, the punctures 

 slightly finer and more closely set in front of the deep arcuate
