208 Mr. J. Walton on the genus Bnichus. 



minutely punctured, with larger interspersed impressions, and 

 having a cuneiform Avhite spot at the middle of the base : elytra 

 elongate, with the sides nearly straight, finely punctate-striate, 

 the interstices minutely punctured, about the middle with a trans- 

 verse fascia composed of eight whitish spots on the alternate in- 

 terstices, and between the middle and the apex with another 

 transverse fascia which is flexuous : pygidium with two obscure 

 fuscous spots : anterior legs rufo-testaceous ; posterior femora 

 subdentate, or armed with a short tooth which is more or less 

 distinct. Length 2i lines. 



This species very closely resembles the large varieties of the 

 preceding, and is rather difficult to distinguish without a close ex- 

 amination. I have no doubt, however, it is perfectly distinct ; it 

 is of equal magnitude with No. 1, and invaria])ly larger and 

 longer than the B. rufimanus ; it also dijSfers from the last-named 

 insect in having the thorax at the apex rounder and fuller, the 

 teeth at the sides more distinct, the sinus deeper, and the elytra 

 longer- ; it differs moreover in having the sculpture on the thorax 

 and elytra distinctly Jiner, and this is very evident when the 

 pubescence is scraped off. I received four examples of this spe- 

 cies with the collection of the late Mr. Millard of Bristol, but 

 without any of the preceding. I can vouch for the integrity of 

 this collection being faithfully a British one ; and as it is an Eu- 

 ropean species, I have ventured to introduce it. Dr. Gcrmar, to 

 whom I sent specimens, regards it as a new species, yet I have 

 a strong impression that it is the same which Schonherr has 

 described under the name of B. flavimanus.

This species has the four basal joints of the antennre (rarely 

 three) rufo-testaceous, the remainder black : the thorax in the 

 middle armed on each side with a minute tooth frequently con- 

 cealed by the pubescence — distinct in the males, but obsolete in the 

 females ; the anterior legs rufo-testaceous, with the femora more 

 or less black, sometimes entirely black ; the anterior tarsi gene- 

 rally pale, but piceous in some individuals ; the intermediate tibiae 

 near the apex within, armed in the males with a small but distinct 

 tooth placed at right angles with the tibiae ; the posterior femora 

 before the apex, beneath, deeply eniarginated ; the acute angle 

 before the sinus in some examples is not produced, in others
