324 Mr. Bates on new species of 



rounded, the greatest widtli being a little before the middle, 

 and posteriorly slightly sinuate and narrowed to the rounded 

 hind angles. The elytra are conspicuously sinu.ated towards 

 the apex, and the latter is produced (although roiinded near 

 the sutural angle) ; in L, cursor, there is no trace of this 

 pecuHar formation.

The genus Zargus, WoUaston, Insecta Madcrensia, ji. 31 

 (1854) is closely allied to, if not identical with, Lestignathus, Er. 

 (1842). 



Scopodes Tasmnnicns. 



Oblongus, oranino niger, elytris fortissimo sericeo-micantibus ; 

 labi-o antice triangulariter valde jn'oducto, apice obtuso, cnnvexo, 

 Iffivi : cajjite supra minus recte striolato : thorace valde trans- 

 verso, quadrato, angulis anticis rotundatis, posticis obtusis, 

 marginibus anticis et posticis medio pauUo rotundatis, lateralibus 

 medio sinuatis ; supra subtiliter transversim striolato : elytris 

 oblongis, humeris distincte sed obtuse angulatis, apice leviter 

 sinuatim truncatis, supra Isete undulato-sericeis utrinque 3 foveo- 

 latis, striis latis vage impressis. Long, 6 mm. 



A large, oblong, rather parallel-sided species, distinguished 

 from all others known to me by the broad and short, quadrate 

 thorax. The eyes are very large and protuberant ; the labrum 

 strongly advanced in the middle, the obtuse point reaching 

 beyond the mandibles when closed. The thorax equals in width 

 the head (with the eyes), and is but slightly narrowed behind. 

 The anterior margin (hke the posterior) is a httle arcuated 

 forward in the middle ; the anterior angles are rounded, the 

 lateral margin before the middle gradually and very slightly 

 siuuated, the hind angles being distinct but obtuse and reflexed. 

 The whole insect is dee]) black, brightly shining beneath, and 

 extremely lustrous or satiny on the elytra. 



Generally distributed (Simson, Atkinson). 



Mr. Simson has sent also a single exam])le of the apparently 

 rare Scopodes boops (Erichson).
