groove ; discoidal fovea very small. Elytra rather elongate, narrowed at base, 

 shoulders prominent, dorsal striae deep but very short, curved, arising from a small 

 deep puncture at base, midway between humeral angle and suture ; sutural strise 

 straight, a puncture at base of each near scutellum, a regular row of distinct punc- 

 tures on each side of suture. Abdomen elongate, slightly convex, without any 

 trace of basal depressions. The whole insect is delicately punctured, but, with the 

 exception of the sutural row, the punctuation is entirely connected with the 

 pubescence. Some of my specimens have the femora and tibise more thickened in 

 middle than others, and I am inclined to think these must be males, but after a 

 careful examination, I am unable to point out any other difference between the 

 sexes. Reitter describes the $ as having a fine longitudinal groove on the abdomen, 

 the anal segment of which has a longitudinal keel. 



I first captured this well-marked species (now recorded for the 

 first time as British) in Sherwood Forest, in May, 1884, on which oc- 

 casion 1 took a single specimen. On re-visiting the same locality in 

 September, 1885, I had the pleasure of finding four additional ex- 

 amples. All of them occurred under bark of beech and oak logs. 



Herr Eeitter, to whom I am indebted for his kindness in deter- 

 mining the species for me, says that this beetle is found in the 

 mountainous parts of Moravia and Silesia, Hungary, Caucasus, &c. 



B. Elytra without dorsal striae. 



1. E. AMBiGUUS, Eeich. 



Long., 1 mm. Pitch-brown, covered with a fine grey pubescence. Mouth, an- 

 tennae and legs dirty yellow, club of antennae and femora sometimes smoky. Head 

 rather elongate, widest behind, considerably narrowed in front, with two large deep 

 punctures between eyes, from which proceed two strongly impressed grooves con- 

 verging in front ; eyes rather prominent. Thorax broadest near the fore part, not 

 very strongly narrowed behind, with three deep foveae near the base, central one the 

 largest, connected by a fine, rather deep transverse groove ; no discoidal fovea. 

 Elytra without dorsal striae, but with six large punctures at base, the outer pair 

 being the strongest. No depressed area at base of first two abdominal segments. 

 Intermediate tibiae of $ with a spur at apex. 



This seems to be a scarce species ; the only occasion on which ] 

 ever found it was some years since at Tewkesbury, soon after an 

 extensive flood. My specimens occurred in moss stripped from poplar 

 trunks, and would appear to have been driven there for refuge, the 

 flood having encircled the trees. All subsequent attempts to procure 

 further specimens from the same locality resulted in failure. 



2. E. MiNiJTissiMUS, Aube, Mon. Psel., p. 59. Tl. Garneysi, Eowler, Ent. Mo. 



Mag., xvi, 158 (1879). 

 Long., 0'9 mm. Most nearly allied to i", amhiguus, but readily separated by 

 its lighter colour and linear form ; the eyes also are smaller, and the $ has a rather 

 long pointed process at the apex of the abdomen.
