STAPHYLINID^. 59 



Q. riparius, Kellner. Stett. Ent. Zeit. 1843, iv. 31. Fusiform, 

 slender, black, the head and thorax being very shiny with a very faint 

 tinge of green in certain lights, elytra with a slight bronze reflection, 

 rarely bluish ; head sub-orbicular, e3'es large and rather projecting, 

 antennse pitchy black, rather long and slender, second joint much 

 shorter than the first and third, 4-7 much, 8-10 slightly, longer than 

 broad, the last joint about one-third longer than the penultimate, the 

 basal half of the second joint and the base of the following four or five 

 joints testaceous ; elytra long, widest behind, somewhat dull owing to the 

 rather dense punctuation and pvibescence; hind body iridescent, 

 pubescent, the pubescence being thicker and paler at the base of each 

 segment, and forming a triangular patch on either side (arranged 

 much the same as the golden pubescence on the abdomen of Q. auricormis, 

 Kies), all these parts being furnished with strong outstanding black 

 setaj; legs pitchy -black, knees and tarsi lighter, the anterior tarsi 

 strongly dilated in both sexes. 



Male with the last ventral segment plainly emarginate angularly at 

 apex, with a smooth oblong space before the emargination. L. 6-7 mm. 



Taken sparingly at Porlock, Exmoor, by the late Mr. W. G. Blatch, 

 and introduced by him as British (Ent. Mo. Mag. xxxii. (2 Ser. vii.), 

 1896, 80). Beauly Castle, Inverness-shire (Chitty) ; Bovey Tracy, 

 Devon (Keys) ; banks of R. Wye, Derbyshire (Kidson Taylor) ; Cusop 

 Dingle, Herefordshire (Tomlin). Professor Beare and Mr. Donisthoi-pe 

 found it in some numbers at Porlock in 1907. This species is very 

 distinct ; it has been found in similar situations in the Alps and 

 Pyi^enees and in the Thiiringer Wald in Germany, &c. Mulsant and 

 Rey. compare it with Q. mesomelinus, from which it differs in its 

 smaller size and larger eyes ; it comes near Q. maurorufus (both 

 belonging to the Sanridns group), but may easily be distinguished 

 from that species by its colour and pubescence. 



Q. kraatzii, Bris. Ann. Soc. Ent. Fr., 1859, Bull. 231. Rather 

 narrow, sub-fusiform, pitch-black with a slight bronze reflection, elytra 

 dark pitchy-red, with the apical border light ; hind body slightly 

 iridescent, pitchy, with the apex of the segments lighter, clothed with 

 more or less close yellowish-white pubescence, which lies in thick patches 

 on the sides of the segments; head sub-orbicular, narrower than the 

 thorax, with four punctures on the front ; antennae rather long and 

 scarcely thickened, dark with the base lighter, thorax about as long as 

 broad, very shiny ; elytra a little longer than broad, about a third 

 longer than the thorax, finely and thickly punctured and pubescent; 

 hind body strongly narrowed to apex with long setse at the sides, and 

 pubescent as above stated in patches on each side, which are very 

 distinct if the insect is viewed from behind in a strong light ; legs 

 testaceous with the tibiae and base of the tarsi darker, anterior tarsi 

 dilated, postei-ior tarsi with the first joint about equal to the two 

 following together. L. 5|-6| mm. Mr. Donisthorpe points out that 

 the male, which was unknown, has the anterior tarsi more sti'ongly
