In the Entomologist's Monthly Magazine, vol. ii., p. 152. Mr. Rye 

 stated that he had taken specimens at Rannoch, which he considered 

 to be the 0. amliguus of Schonherr (recorded as British by De Mar- 

 seul, Cat. Col. d'Europe, 1863, and Stierlin), in company with 0. rugi- 

 frons, to which it appeared to be very closely allied, if indeed the two 

 insects were not specifically identical. Mr. Rye thus describes his 

 insect (Ent. Ann. 1867, p. 87) : "It appears to be somewhat narrower 

 than 0. rugifrons, and clothed more thickly with hairs ; the thorax is 

 somewhat more finely granulated, and the elytra are more finely 

 punctate-striate, with the granulations of the interstices not arranged 

 in such distinct rows. The rostrum and vertex are more rugosely 

 punctate, the punctures running into longitudinal ru guise ; the former 

 also is distinctly keeled in the middle, with an obsolete longitudinal 

 furrow on each side. The second joint of the funiculus should be 

 almost shorter than the first, instead of somewhat longer as in 0. rugi- 

 frons : " it will be noticed that the differences are very slight and com- 

 parative, and with respect to the central carina of the rostrum, which is 

 supposed to be simply rugose longitudinally in 0. rugifrons, it appears 

 certainly to be present to a greater or a less degree in the last-named 

 insect ; whether 0. ambiijuus is really a separate species or not remains 

 to be proved, but our British specimens are certainly very doubtfully 

 distinct from 0. ruc/ifrons, even as a variety. The presence of a small 

 tooth on the anterior femora and the colour as well as the greater 

 distance of the eyes from one another on the forehead will separate 

 this species from 0. liyneus ; from O. ovatus it may be easily known by 

 its average larger size, duller appearance, much smaller tooth on the 

 anterior femora, and the absence of longitudinal sulci on the thorax, 

 which is much more finely granulated. 



O. ovatus, L. Black, rather shining, clothed with thin griseous 

 pubescence ; head and rostrum even or almost even with an impression 

 between eyes (which are comparatively prominent), finely and rugosely 

 punctured ; antennae red ; thorax very convex, subglobose, very coarsely 

 granulate, the granulations on disc coalescing and forming longitudinal 

 ridges and deep suLi ; elytra convex, somewhat acuminate at apex, with 

 coarse punctured striae, interstices finely shagreened on disc, more rugose 

 at sides ; legs red, anterior femora with a strong tooth ; reddish varieties
