the ninth stria, which forms the edge of the elytron as it is preserved, 

 shows no appearance whatever of ocellate punctures, although under the 

 microscope some of the central strise show slight signs of faintly indicated 

 punctures near the middle of the elytron.

Of this species a pair of elytra are preserved nearly complete, but cracked 

 and flattened somewhat out of shape. It is allied to L. ccerulescens L., 

 but differs from it and from all other American species of Loricera in the 

 much greater depth of the striae and in the presence of distinct submarginal 

 fovese. The elytra are of a glistening, somewhat blue-black colour. The 

 strise are strongly impressed, faintly though rather coarsely and profusely 

 punctuiate, the third interspace with three small, distinctly but not deeply 

 impressed fovese, arranged as in L. ccerulescens, two near each other just 

 above the middle of the elytra, and one behind the middle of the apical 

 half ; fifth interspace sometimes furnished with a pair of very faint fovese 

 near the middle of the elytra, much as in L. decempunctata Esch., about 

 as far from each other as from the sutural border ; and finally the ninth 

 interspace, different from all the species of Loricera I have been able to 

 examine, has eight or more small but distinct 'and deep fovefe, mostly 

 situated in the apical half of the elytra, sometimes connected by oblique 

 ridges with the next stria within. The interspaces are crossed by very 

 fine wrinkles, scarcely visible with a simple lens. Seen on the under 

 surface, each of the punctures of the strife are surrounded by a circle 

 reaching to the circles around the adjoining punctures, reminding one 

 somewhat of the upper surface of Elaphrus. The elytra are shaped as in 

 L. decempunctata, particularly at the apex.

Loricera ccerulescens is found in northern Europe and also in Michigan
