" Another species of much smaller size than the i)receding [U. alutaceus 

 Horn] is indicated by an impression of the greater part of l)Oth elytra and 

 a very small fragment of one elytron, resembling D. elongatus. The carina 

 appears to be of similar length and the interv^als moderately convex, equal 

 and smooth. 



"No measurements can be given as I have not sufficient material on 

 which to base them and I must also leave the species nameless." Horn, 

 loc cit. 



I have seen only the specimen figured. The surface sculpturing is the 

 same as in D. alutaceus, but the species being smaller the striaj are of course 

 closer ; but in addition to this there are more of them, as there are nine in 

 all ; their average distance apart in the middle of the elytron is 0.4°"". The 

 width of the two elytra together is 7°"". 



The fragment is too imperfect to require a name at present.

A fragment of an elytron indicates a species closely allied to F. hercu- 

 laneus Mann, in elytral structure and of probably about the same size. 

 The sutural stria is similar ; there are the same broad and deep, simple 

 striae, onl}' they are, if anything, broader and d'eeper in the fossil. The 

 interspaces are, however, flatter than in the recent species, and the intimate 

 texture of the surface, instead of showing a very distinct reticulation of 

 minute imbi'icated cells with sharply defined walls, is almost entirely smooth, 

 the faintest sign only of such tracery being visible with strong magnifica- 

 tion. The first stria is also at an unusual distance from the margin. The 

 color is piceous. 



Length of fragment, 5""" ; width of same, 2°"" ; presumed length of 

 elytron, 7.5"™.
