EoriceraJ lutosa. 



Loricera? lutosa SctroD., Tert. Ins. N.A., 533-534, PI. i, fig. 32 (1890). 



A single elytron in a perfect state of preservation. It is almost two 

 and a-half times longer than broad, scarcely broader in the middle than at 

 the base, the humeral angle roundly angulated. There are ten series of 

 very coarsely punctured strise, the four inner running almost to the apical 

 margin, the others, however, curving inward to abut against them, the 

 outermost meeting the innermost at the apex ; the elevated narrow inter- 

 spaces smooth and shining : the whole piceous. 



This can hardly be referred to Loricera, but I can find no other genus 



with which it better agrees. I am inclined to the belief that it will be 



found to belong to an extinct type of Loricerini. There seems to be, as 



there, a faint internal plica, but the specimen is broken only at just this 



■ point.

Maphrus irregularis Sot7DD., Tert. Ins. N. A., 534, PL i, fig. 56 (1890). 



An elytron only is preserved, which by its surface sculpture appears to 

 resemble U. viridis, of California (which I have not seen), more than any 

 other, though in size it agrees better with B. riparius and H. ruscarius, 

 the nearest allied of the species I have examined. The elytron is distinctly 

 slenderer than in these latter species, with the middle scarcely, if at all, 

 wider than the base, but with entirely similar apex. Surface uniformly 

 punctured, the punctures coarser than in U. riparius, with ill-defined 

 obscure fove^, the basal one of the second series from the suture being 

 the only one as distinct as in E. riparius ; spaces between the fovese 

 remarkably elevated, forming longitudinal, more or less tortuous ridges 

 which are highest (and rarely poHshed) in longitudinal dashes as long as 

 the diameter of the fovese and in the same lines with them, i. e., between 

 foveK of the same longitudinal series and not in the interspaces between 

 the series. It is in these elevated spaces that its relationship to H. viridis 

 especially appears, and their irregularity, through their more or less 

 tortuous, connecting, less elevated ridges, which has suggested the name. 

 Colour dull piceous, with faint dark metallic green reflection, which is 

 quite distinct on the inflected margin.
