and the depression, which is narrower anteriorly and widens out 

 in a somewhat arcuate manner posteriorly, is closely covered with 

 a black tomentum. 



Some female examples from Mamboia and from Delagoa Bay 

 agree with the example from Zomba in presenting the characters 

 detailed above. 



In a male example from Natal, which in all probability belongs 

 to this species, the following sexual differences may be jaoted : — 

 The first abdominal segment is entirely of a pale yello\\ish- white 

 colour ; the last ventral segment is flattened or slightly concave from 

 side to side along the middle, and is only very faintly pubescent.

46. Sagea johnstoni, sp. n. 



Cyaiua, elytris viridibus subnitidis leviter cupreo-tinctis. 

 S • Femorihus jiosticis basi intus fidvo-tomentosis, projiye apicem 

 stibtus bidentatis, dente postica pauUo majore ; femoribus inter- 

 mediis subius obtuse dentatis vel tuberculatis ; segmento basali 

 abdominis medio longitudincditer subdepresso, crebre jjunctulato, 

 et fulvo-jiubescente. Long. 14, lat. 5| mm. 

 This species seems to be most nearly allied to S. bicolor, Lac. 

 (=festiva, Grerst.), of which it has the general form. The oblique 

 depression at the base of each elytron just above the shoulder is, 

 however, more strongly marked ; the elytra are more niiid and are 

 greenish rather than purplish in colour ; and the hind femora are 

 each armed underneath near the apex with two small teeth on the 

 outer edge, the distal tooth being only slightly larger than the 

 proximal one.

Sujpra obscure viridis, elgtris interdum violaceo plus minusve tinctis; 



pronoto sat deme punctato, interstitiis minutius punctidatis ; 



elytris crebre punctatis, sidjrugulosis, interstitiis minute punctu- 



latis ; corpore subtus cyaneo-violaceo.i pedibus cyaneis ; articulis 



ipiinque idtimis antennarum sat fortiter dilatatis. Long. 12 mm. 



Upperside of a rather dark greenish colour, with the elytra in 



some examples more or less strongly tinged with violet or purple. 



Pronotum with some larger and less thickly distributed punctures, 



the intervals between which are thickly and minutely puuctulate. 



Elytra closely punctured, with many of the punctures drawn out 



in a transverse direction so as to give to the elytra a slightly 



rugulose appearance, and with the interstices between the punctures 



very minutely punctulate. 



In general form this species resembles C. compressicomk, Fabr., 

 but differs in having the distal five joints of the aiiteunte a little 

 more strongly dilated, and the pronoLum and elytra more thickly 

 puuctured.
