1906.] COLEOPTERA OF THE GENUS SCIOBIUS. 273 



and moderately slender, piceous and with fine grey pubescence ; 

 the scape not much curved, rather compressed and gradually 

 clavate ; the first joint of the funicle thickened, as long as the 

 third. Prothorax rather transverse, gently rounded at the base, 

 narrower and truncate at the apex, sides gradually dilated from 

 base to beyond middle, thence rapidly narrowed to apex ; upper 

 surface convex, closely set with low rounded granules, but with a 

 more or less distinct smooth central line ; colour black, the 

 granules bare, the interstices with fine grey pubescence which is 

 denser at the sides. Elytra elongato- ovate, scarcely broader in 

 the 5 , jointly sinuate at base and a little broader than the pro- 

 thorax, shoulders very oblique, sides not much rounded, broadest 

 about middle; upper surface convex, with distinct strife, which 

 appear to contain rows of deep punctures or rows of small distant 

 granules according to the incidence of the light ; the intervals 

 convex, the first, third, and fifth more raised and rather narrower 

 than the others, especially near the base, impunctate and without 

 granules; colour black, with ver}^ fine shoi't recumbent grey 

 pubescence. Legs moderately long and slender, black with fine 

 pale pubescence ; the anterior tibiee in the S dilated internally in 

 the middle and with a very deep sinuation near the apex, the 

 first joint of the tarsi broad but scarcely as long as the next two 

 together ; the anterior tibiae much less sinuate in the § .

Nearly allied to S. poUinosus Fahr., but it is a larger and 

 narrower insect. It difiers also in the deeper and closer punctua- 

 tion of the head, the broader and more gradually dilated scape, 

 the shorter third joint of the funicle, the slight elevation of the 

 alternate intervals of the elytra, the greater sinuation of the 

 anterior tibise in the c? , and finally the first joint of the tarsus 

 is less elongate. 



The only three specimens which I have seen were kindly sent 

 me by Dr. Walther Horn, of Berlin. Unfortunately they are 

 evidently much rubbed, and probably in fresh examples the 

 pubescence would bear some powdering similar to that of 

 poUinosus.

Read moderately transverse, black, with fine close punctuation 

 which is often more rugose near the eyes, and densely covered 

 with metallic green scaling, there being usually three subdenuded 

 lines corresponding with the rostral carinje ; forehead scai'celv 

 impressed ; e)'es not at all pi-ominent. Hostrutn distinctly longei- 

 than broad, its sides subparallel to beyond middle, the gense onh- 

 slightly and roundly dilated in both sexes ; upper surface shallowly 

 impressed, with three distinct narrow and evenly raised carin^e, the
