sides nearly straight but narrowed towards tlie acute anterior angles, 

 apex widely emarginate ; its sculpture consists of shallow, oviform, 

 ocelli - like punctures. Elytra feebly striate ; interstices broad, 

 densely and minutely granulose. Le(js stout ; anterior tibite a little 

 curved externally and feebly tridentate, they are bent and swollen, 

 there is a wide deep emargination on the inside beyond the middle 

 causing the terminal portion to appear much dilated, apex obliquely 

 truncate, the upper face more or less furrowed and sculptured. 



In the other described species, except S. squamulosus, the sides, 

 of the thorax are rather abruptly contracted in front, thus forming 

 an obtuse angle at each side, in the present species such is not the 

 case. The form of the front tibiae is quite distinctive.

One example, discovered near Clevedon by Mr. George Munro. 



1972. S. fuSCUS, "••5- Convex, ovate-quadrate : subopaque, 

 clothed with tine decumbent yellow setae, rufo-fuscous, legs clear 

 pitchy-red, antennae and palpi fulvous. 



This species approaches S. inflatipes in form and sculpture, but 

 the hind-hody is shorter and more rounded. The front tibiae are 

 quite different ; these are inwardly curvate, dilated towards the ex- 

 tremity, which part is obliquely truncate, and not armed with the 

 projecting calca,r that may be seen in the typical form (No. 451), 

 externally they are distinctly tridentate. 



Length, 2^ ; breadth, 1|- lines. 



My specimen was found amongst decaying leaves, near Howick. 



Obs. — As the structure of the anterior tibiae presents good dis- 

 tingiiishing characters, I give some details of those species I have 

 been able to examine. 



The following species have the extremity dilated and subtruncate, 

 and the protruding calcar obsolete or altogether absent : S. squamu- 

 losus, S. sctosus, S. inflatipes, and S.fitscus. 



In S. edwardsi and <S'. nitidulus the three outer teeth or projec- 

 tions are very conspicuous, but in the latter species the third or 

 apical one is scarcely more prominent than the first. 



In the four first-mentioned species the external denticulations are 

 sometimes greatly reduced, the first or uppermost being often quite 

 obsolete. 



1973. S. setoSUS, 'i-i'- {Sharp; Trans. Boy. Dub. Soc., 1886, 

 p. 398.) Breviter ovalis, latus, fusco-niger, opacus, supra breviter 

 setosus, pedibus piceis, antennis pallide fiavis ; tihiis anterioribus 

 exttts ante apicem angulatis, intus valde curvatis, apice obliquo, 

 dilatato. 



Long., 4-^mm. 



This is readily distinguished from the other species by the setose 

 surface, and the peculiar shape of the front tibitE ; the latter of these 

 characters may prove to be found in the male only. The broad liead 

 is densely punctate, bidenticulate in front. The thorax is moderately 

 closely punctured, indistinctly depressed along the middle behind.
