group of the genus which, from the slender outline and the 

 peculiar conformation of the prothorax, bears a strong resem- 

 blance in miniature to Toxotus. 



I may further observe that the elytra of the specimen above 

 described may be equally well said to be pale, with a broad 

 black sutural stripe, and a broad black dorsal vitta extending 

 from the humeri nearly to the tip. 



Leptura scrtjjta. 



Elongata, fusca, parce pubescens ; capite thoraceque confertim Bubtilius 

 punctatis, hoc apice angustiore, tubulatim profunda constricto ; 

 basi transversim impresso, lateribus medio rotundatis, subangulatis, 

 antice posticeque concavis, angulis posticis haud prolongatis ; 

 elytris fortius punctatis, thorace latioribus, parallelis, apice rotun- 

 datis subtruncatis, pallide testaceis, lituris nigris oruatis (viz. 

 striga angusta discoidali a basi fere ad medium extensa, macula 

 lateral! duplici ad medium, alterisque duabus approximatis ad do- 

 drantem, exteriore submarginali) ; antennis pedibusque testaceis, 

 femoribus posticis extrorsum late infuscatis. 



Long. lOmillim. 



One female. Belongs to the same group as L. s])hcericollisj 

 and related in form and sculpture to L. aurata, but quite dis- 

 tinct by the peculiar coloration. The black markings of the 

 elytra above mentioned are a narrow line extending from the 

 base to about the middle, slightly oblique and gradually nar- 

 rowed behind, a lateral or submarginal spot at the middle, 

 composed of two confluent spots, and an imperfect band behind 

 the middle, half way between the spot just described and the 

 tip ; this band is composed of an elongate submarginal spot 

 and a smaller discoidal one ; there is, besides, a very faint 

 fuscous cloud on the side margin near the base : the scutellum 

 and the suture for a short distance are also black. 



Leptura Matthewsii. 



Nigra, pubescens ; elytris a basi paulo angustatia, confertim subtUius 

 punctatis, flavo-testaceis, apice late et macula magna pone medium 

 ad marginem extensa nigro-piceis, apice singulatim rotundatis ru- 

 fescentibus ; prothorace latitudine breviore, apice valde angustato 

 et fortiter tubulatim constricto, lateribus obtuse angulatis, pone 

 medium fere parallelis, angulis posticis brevibus acutis, basi late 

 bisinuato, disco confertissime fortiter punctate, ante basin profunde 

 transversim impresso. 



Long. 20 millim., lat. 7 millim. 



One female. Somewhat related to L. cordifera, but much 

 larger, therefore rcseml)ling L. ohJiferafa and vitiosa, Avhicli,
