1906.] COLEOPTERA OF THE GENUS SCIOBIUS. 243 



1. SCIOBIUS GRANOSUS Falir. 



S. granosus Fahr. (Efv. K. Yet.-Ak. Forh. 1871, p. 27, 

 Long. 10-13, lat. 5-6| mm. 



Head twice as broad as its length, with scattered punctuation 

 and sparse j^ellow scaling ; forehead with an ill-defined central 

 impression and a slight tubercular elevation above the eyes, which 

 are very prominent. Rostrum longer than broad, as long as pro- 

 thorax, tricarinate dorsally, and with a short lateral carina just in 

 front of eye ; genas produced in c? into a long (li mm.) re- 

 curved horn-like process, rounded and only slightly prominent in 

 5 ) T-ipper surface with irregular shallow punctuation and dense 

 ochreous scaling. Antennce moderately long, piceous, irregularly 

 aciculate and with fine pale pubescence ; scape compressed and 

 gently curved, third joint of funicle scarcely longer than first. 

 Prothorax very transverse, sides strongly rounded, especially in 

 the (S , broadest about middle, base truncate, apex narrower and 

 slightly sinuate, with a faint constriction and an impressed trans- 

 verse line close to the margin ; upper surface convex, but flattened 

 in the median basal area and fairly closely covered with smootli 

 depressed tubercles ; the interstices are thinly clothed with ochreous 

 scales, and there is a short curved lateral impression on each side 

 near the base. Elytra broadlj^ ovate, shoulders obliquely rounded, 

 sides ampliated, broadest near base ; upper surface convex in 5 , 

 subdepressed in S , with shallow stri^ containing rows of distinct 

 separated granules ; the intervals with rows of low rovinded 

 tubercles, which are absent on the inflexed margins, the striae 

 there being also simply punctate ; colour black or piceous brown, 

 granules and tubercles bare and shiny, the interstices with thin 

 yellowish scaling. Legs stout, tliicker in the J , black or piceous 

 brown, finely aciculate and sparsely punctured, with yellowish 

 scales and setse which are dense near the apex of femora ; the 

 anterior pairs of tibiee broader and more strongly curved in 

 the c?.

It is evident from his description that Fahrseus took the c? 

 of this species for the $ , both sexes being represented in 

 Wahlberg's series. It is curious that he makes no reference to 

 the striking horn-like rostral processes of the S , which distinguish 

 it from all other species of the genus except ;S'. cidtratus. 



2. SciOBius cuLTRATUS, sp. nov. (Plate XVIII. fig. 1.) 



Long. 8f-10i, lat. 4^-54 mm. 



Head strongly transverse, finely aciculate and with rather thin 

 grey scaling ; forehead finely plicate, with no distinct impressions ; 

 eyes prominent. Rosirura distinctly longer than its width at 

 base ; in the S the sides are somewhat narrowed from the base to 

 about middle, and the gente are produced into broad but sharp
