P. 61. Ptenidium laticolle. 



Hoch. Bull. Mosc. 1872, li. p. 214. 



•• L. c. - 6 rum. — Allied to P. fiueieorru, but rather larger, and easily distinguished by 

 the thor ly rounded at the sides behind, and distinctly broader than the elytra ; 



very shinin g, black, and smooth : antennae and legs entirely pale yellow : sometimes the 

 \ of the elytra is also pale. Ti: 1th of the thorax is rather behind the 



middle, and is there one quarter broader than the elytra at the base, and also broader than 

 they are at the middle ; elytra suboval, widest before the middle. The foveolate punctures 

 peculiar to this genus are sometimes distinct, sometimes indistinct, sometimes two in 

 number, sometimes four, sometimes altogether wanting. Hab. Tue South of Russia. Kiew." 



P. 61. Ptenidium longicorne. 



Fiiss. Berl. Ent. Zeit. 1868, p. 357. 



■• I., c. 8 mm. — Black, shining, in shape much like /'. apieale, but distinctly larger, 

 elytra widest behind the shoulders, pubescence very short and scattered; antennae longer 

 than the head and thorax, reddish brown, the last joint furnished with very long grey 

 hairs: uead smooth; prothorax dis irrower than the elytra, with the anterior 



angles rounded, posterior very o les faintly rounded at the middle, above convex, 



very faintly and sparingly punctured, with a distinct impression on each side at the 

 posterior angles, and two small indistinct fovea? above the scutellum ; scutellum large, 

 triangular; elytra widi the middle, gradually narrowed towards the apex, which 



is transparent brown and Separately rounded, and ornamented with small punctures, which 

 are mor i than in P. . and disposed in striae : suture slightly elevated 



posteriorly ; legs brownish yellow. Hab. Germany, Ahrweiler." 



P. 62. Ptenidium caecum. 



Joseph, Berl. Ent. Zeit. 1882, p. 46. 



• L. c. 0-6 mm.— Allied to P. laxigatum i Gillm. i. Without .v. .-. a] terous, transparent 

 yellow ; antennae half as long as the body ; prothorax slightly broader than long ; elytra 

 flattened, separately rounded behind. Hab. Carniola, from the Grotte de Lueg." 



P. 63. Ptinella biimpressa. 



Renter, Deuts. Em. Zeit. 1878, p. 48. 



•• L. c. 0-8 mm. — Elongate, subparallel, depressed, pale yellow, rather thickly clothed 

 with short pale hair : head large, obtuse in front ; prothorax transverse, rather broader 

 than long, rather longer bat scarcely broader than the head, sides slightly dilated, rounded 

 in front, contracted towards tue base, posterior angles ob very obsoletel; aluta- 



ceous l<- I ittened and very faintly marked with two impressions ; elytra rather long, 



subparallel ; legs thickly and very faintly asperate : abdomen broad, and obtusely rounded 

 at the apex. Hab. X. Hungary, C'sap." 



•• This species belongs to the group with the abdomen obtusely rounded at the apex, as 

 /'. Britaitnica, P. test . and P. Maria, it may be distinguished by the 



obtuse angles and flattened disc of the thorax with two longitudinal impressions more or 

 less distinct, but always visible ; also by its long aud almost parallel elytra, and short 

 obtuse abdomen." 



In the foregoing description all the characters agree entirely with P. Britonnico, except 

 that Herr Reitter does not mention the remarkable prolongation of the head, and the 

 backward position of the eyes. 



I may add here that in the collection of M. Jekel there are two specimens labelled 

 •• N. tcaphidij vuich are not in any way distinguishable from N. piloseilum.
