492 Descriptive Catalogue [1896. 



pubescence, moderately shining, the extreme edge of the outer margin 

 with a cerulean tinge, hardly convex, narrowly striated with the 

 intervals much raised, subcarinated in the middle and having on 

 each side a series of deep, elongated punctures ; under side and legs 

 black, shining ; pectus very closely punctured, the punctures setige- 

 rous. Length 33 mm. ; width 12 mm. 



This ChlcBJiius, probably the giant of the group, occurs also on the 

 Zanzibar mainland (Bagamoyo). 



Hab. Zambezia (Victoria Falls). 



Chl^nius c^ruleolimbatus. 



Black, moderately shining ; elytra with a faint bluish-black tinge ; 

 lateral sides of prothorax and outer margins of the elytra with a 

 moderately broad cerulean band ; head closely punctured laterally 

 and behind, the punctures moderately deep, regular, and leaving a 

 frontal space smooth ; prothorax not broader at the apex than at the 

 base, and broader than long by one-fifth in the middle, very narrowly 

 grooved in the centre, and covered with moderately deep irregularly 

 arranged punctures ; elytra elongated, nearly parallel, hardly convex, 

 moderately shining, narrowly striated, the striae with a series of 

 narrow punctures on each side of the intervals, which are raised and 

 subcarinate at the tip ; pectus slightly pilose, cyaneous black ; abdo- 

 men and legs black, shining. 



Allied to the preceding species, but differentiated by the punc- 

 tures on the prothorax, which are neither so deep nor so broad ; the 

 raised intervals on the elytra are not so much raised, and the punc- 

 tures on each side of the carinas are neither so w^ell defined nor 

 so deep as in C. Zanziharicus. Length 33 mm. ; width 12 mm. 



Hah. Mozambique (Pungwe River). 



Chl^nius lugens, Chaud., 

 Monogr. Chlen., p. 185; Ann. d. Mus. Gen., viii., 1876. 



The description of this species agrees entirely with that of C. 

 ccEruleolimhatus, but it is only half the size ; the head is punctate 

 in the same manner, but there is no median impression on the 

 labrum ; the punctures on the prothorax are less densely set, and 

 the outer margin is also cerulean blue ; the elytra have the same 

 shape, the intervals are equally raised, but the striae are distinctly 

 punctate, the outer margin has a narrow bluish band, and is some- 

 what pubescent, while the striae have a few distant very short 

 decumbent greyish-white hairs thicker towards the apex ; under side 

 and legs shining. Length 19-20 mm. ; width 7 mm. 



Hah. Delagoa Bay (Louren^o-Marquez, Eikatla), Ovampoland. 



Occurs also on the shores of the White Nile, according to De 

 Chaudoir.
