eurvcdj ratlirr stout, dilated on each Ride at the insertion of tlie 

 antennre, and jribbous beneath. Antennfr medial, black, the basal 

 joint liilvous, lonijest, considerably dilated at the apex, Torniinf^ 

 a j)vritonn club, the second oval, minute, three followinir cxceed- 

 intrly minute, sixth and seventh veiT long, eighth stout, long- 

 obconic, the renuiinder forming an elongate club distinctly arti- 

 culated, the twelfth being minute, conic. Thorax subglobose, 

 dilated and rounded at the sides, above very convex, thickly 

 and deeply punctiu'cd, the punctures continent, with a deep 

 dorsal channel. Elytra ovate, shining blue-black, very convex, 

 punctate-striatc, the interstices broad, Hat and coriaceous. The 

 nuicro of the epigastrium elevated and dilated, armed on each 

 side with an acute tooth. Legs fulvous, robust, with the four 

 posterior coxai, the lower lialf of all the tibi?e and the tarsi black ; 

 the anterior tarsi have the basal joint short and stout, armed at 

 the a})ex within with an acute tooth, the second joint at the 

 base within also armed with an acute tooth, which is parallel to 

 the Hrst ; the four posterior tibiaj are distinctly stouter than the 

 anterior pair, bent, and each gradually thickened from the base 

 to the apex ; the two first joints of all the tarsi dilated ; the basal 

 joint of the posterior pair parallelogramical ; the three first joints 

 of all the tarsi, especially the posterior pair, concavo-convex, and 

 clothed beneath with a pulvillus. J. (Length 1;^ Hne.) 



The female differs in having the head generally narrower, 

 striated between the eyes, the frons posteriorly closely punctu- 

 lated; the rostrum longer, slender and filiform; the antenoie 

 placed behind the middle of the rostrum, the basal joint black or 

 piceous, slender, a little dilated at the apex, the second long- 

 ovate, the six following nearly of equal lengtli, loug-obconic ; the 

 legs comparatively slender ; the four posterior tibite as long as 

 the anterior, of equal thickness and nearly straight ; the two first 

 joints of all the tarsi shghtly dilated ; the anterior tarsi and the 

 mucro of the epigastrium simple. 



This new and extraordinary species offers another example of 

 anomalous form peculiar to the male in the joints of the antcnme 

 and in the construction of the legs. 1 first received a single cx- 

 amjde with the collection of the late aIv. Millard of Bristol, which 

 I sent to Gcrmar as a new species, and he retiu-ned it labelled 

 " dissimile 2 ." Si)ecimens of both sexes were afterwards found 

 near Arundel in August, and rather plentifully amongst grass in 

 a field adjacent to Birch Wood in September, by Mr. S. Stevens 

 and myself.

The female of this species has sometimes a broad testaceous 

 ring at the apex of the anterior femora.
