1906.] COLEOPTERA OF THE GENUS SCIOBIUS. 269 



posteriorly, with deep strife containing rows of strong punctures 

 the intei'vals of equal width, moderately bi'oad, slightly convex, 

 quite smooth and very finely alutaceous ; colour black, rather shiny 

 and entirely bare. Legs ferruginous, with the femora black ; 

 anterior tibise straight externally, but distinctly sinuate internally 

 near apex. 



Type 2 iii the Albany Museum, Grahamstown. 



Cape Colony : Steynsburg. 



Yery simila.r to S. nanii,s in general appearance, but the scape 



much longer and more slender, the prothorax lacks the lateral 

 impressions, and the elytra are distinctly acuminate apically. 

 Whethei- the absence of scales is normal is not altogethei' ceitain, 

 but there is not even a trace of them on the elytra in the type 

 specimen. 



33. ScioBius viRiBis, sp. nov. (Plate XIX. fig. 7.) 



Long. 5-61, lat. 2|-3f mm. 



Colour black or piceous, densely and uniformly covered above 

 and below with blight green scaling, which varies to yellowish 

 green or dull golden green. 



Head ti-ansverse, slightly convex, with close shallow punctuation ; 

 forehead scarcely impressed ; eyes not prominent. Rostrum 

 scai'cely longer than broad, arcuate at base, sides gradually con- 

 vergent fi-om base to beyond middle ; genas bluntly angulate, 

 moderately produced in 5 , a little more so in S ', upper surface 

 shallowly impressed, tricarinate, only the central carina bare of 

 scaling, the outer carinaa straight and gradually diverging 

 anteriorly. Antennce moderately long and slender, piceous, with 

 fine grey scaling ; scape not compressed, subcylindrical, regularly 

 curved and gradually clavate ; funicle with the first joint rather 

 longer than third, the subterminal joints subconical and not very 

 long. Prothorax strongly transverse, base faintly bisinuate, apex 

 a little narrower and truncate, sides scarcely rounded and with a 

 shallow constriction at apex ; upper surface convex, finely and 

 evenly coriaceous, without any lateral impressions. Elytra ovate, 

 broader and rather more blunt apically in the $ , slightly sinuate 

 at base, sides strongly rounded, broadest about middle ; upper 

 surface very convex, with fine stride containing small shallow 

 punctures ; the intervals rather broad, subequal in width, almost 

 plane, smooth and impunctate. Legs moderate, ferruginous, with 

 greenish or golden scaling, anterior tibiae straight externally, 

 thicker and with the internal angle more strongly produced in 

 the S . 



Type, 5 in the British Museum, S in the Oxford Museum. 



Transvaal. 



Described from six specimens. One in the Biitish Museum, 

 two in the South African Museum, and the remaining three 

 kindly given me by Dr. Walther Horn. Its dense green scaling 

 in conjunction with its dilated genae and perfectly smooth elytra 

 will sufiiciently distinguish this species.
