Penultimate sejj:ment of ahditmeii feobly mitched. Length, 

 10—13 mm. 



$ Dirters iu being more robust, with shorter and less strongly 

 serrated antennae and simple abdomen. 



The antennae of both sexes are much as in ampliatus ; the 

 entirely black prothorax will readily distinguish it from insignis, 

 which otherwise it strongly resembles. 



121. Me(rior?-]iyn, lilts kiiii^eiisis, u. sp. 



? Black, shoulders very feebly diluted with red. 



Eosfrunt very short. Antennae strongly serrated, scarcely 

 extending to basal third of elytra. Protliorac triareolate, middle 

 areolet narrowly open in front, rather more widely open behind, 

 middle of apex deeply notched. Scutellum concave, apex strongly 

 notched. Elytra wide, subparallel to near apex ; each with 

 four fairly strong costae, and with double rows of large sub- 

 quadrate punctures. Length, 12 J mm. 



The combination of triareolate prothorax, very short mstrum 

 and double rows of elytral punctures will readily distinguish 

 from all other black species hitherto describe-d. The antennae 

 are much as in the male of atratus.

Black, middle of prothorax, tips of elytra, apical half <if 

 abdomen, trochanters, and lower parts of mouth tlavous. With 

 fine pubescence. 



Head with fine punctures. Antennae extendinLT to hind 

 coxae, first joint almost twice the length cif second, slightly 

 longer than third, and slightly shorter than eleventh, fnurth— 

 tenth very feehly decreasing in length. Frothora r almost 

 twice as wide as InuL"", impunrtate, with traces of a feeble 

 median line, margins strongly raised and in front slightly 

 incurved. Elytra with coarse and dense punctures, becoming 

 smaller posteriorly. Length, -ij mm.
