British Species of the Genus Gyrophana. 251 



stronger and slightly incurved at apex ; the inner pair shorter and 

 approximated. 



The very small size of this insect (it being about two-thirds of 

 a line in length) readily distinguishes it from other pale-coloured 

 species. The intermediate joints of the antennae are pretty strongly 

 transverse. Among the punctures of the thorax, those belonging 

 to the dorsal series can be indistinctly traced — a pair of these, on 

 the basal third, and a second pair towards the front of the thorax, 

 are usually more distinct than most of the other punctures. These 

 latter are not numerous, and are somewhat widely separated for 

 the most part. The male characters correspond very nearly witli 

 those of G. gentilis. 



I found this species in Windsor Park in the month of June, and 

 Dr. Power has taken it, in fungus, in a wood near Markfield, 

 Leicestershire. 



9. G. manca, Erichs. Gen. et Sp. Staph. 190, 15. 

 Kraatz, Ins. Deutschl. Staph. 361, 12. 



Piceous ; antennae, legs and tip of the abdomen testaceous; 

 thorax transverse, with numerous scattered punctures on the sur- 

 face, the discoidal rows indistinct ; elytra thickly and finely punc- 

 tured. 



Male with the 7th abdominal segment terminated by two widely 

 separated spines. 



This species slightly exceeds G. minima in size, and is distin- 

 guished not only by its pitchy colouring, and by the absence, in 

 the male, of any distinct ridges on the 6th abdominal segment, but 

 likewise by the relatively more ample thorax and elytra (in G. 

 minima these parts are unusually short); the eyes are proportion- 

 ately larger and more prominent; the thorax less distinctly mar- 

 gined, and the elytra more thickly and finely punctured. The 

 head is gently convex above and presents some scattered punc- 

 tures. The intermediate joints of the antennae are stout and 

 pretty strongly transverse. The posterior margin of the thorax is 

 moderately rounded; the sides more gently rounded; the anterior 

 angles somewhat obtuse ; the surface moderately convex and 

 punctured; the punctures fine and scattered, and on the disc four 

 larger punctures are usually pretty distinct, these being arranged 

 so as to form a square. 



Dr. Power took this insect plentifully under bark on an old 

 stump, among fungous matter, near Thorton Reservoir, near 

 Markfield, Leicestershire, in August, 1860, and it is from some
