72. T. (PterOStichus) SylviuS, Bates; Eiitom. Man. Mag., 

 fitly, 1878, /. 26. Supra viridi-feneus vel cupreo-;«neus, marginibus 

 viridibus, nitidus, palpis apice rufis : thorace transversim quadrato, 

 postice sinuatim angustato, angulis posticis prominentibus, acutis ; 

 clytris oblongis, punctato-striatis, interstitiis convexis, cequalibus, tertio 

 3- vel 4-punctato, septimo pluri-punctato. 



Long., 9 lin. 



Agrees with the description of Ferom'a (T.) rectangida, Chaud., in 

 every important respect, except in the hind angles of the thorax, which, 

 instead of being exacte rcctis, are decidedly projecting. This character 

 is constant in the six examples before me, and is corroborated by the 

 shining metallic colour of the whole upper surface, head included ; 

 Chaudoir giving as a speciality of T. redangitla, "color pagincs siipcrioris 

 minus nitidus, clytroruni dorso fere nigricante." Specimens agreeing with 

 this description were taken by Mr. Wakefield at Rangiora, whereas all 

 his examples of T. sylvius came from Peel Forest. 



T. sylvius has the head of moderate size in both sexes, with promi- 

 nent eyes, and very small rapidly narrowed posterior orbits. The 

 thorax is arcuate-emarginate on the fore margin, with rounded anterior 

 angles, quite as broad at the base as at the apex, and moderately dilate- 

 rotundate at a short distance behind the anterior angles. The elytra are 

 dentate at the humeral angles, the punctures in the striae are small and 

 distinct, and the interstices become flatter towards the apex.

73. T. rectangulus, Chaudoir; Bull. Moscotu, 1865, ii., /. 74. 

 Color pagime superioris minus nitidus, elytrorum dorso fere nigricante. 

 Prfficedente (antarcticus) multo minor, praesertim angustior. Differt 

 pneterea fronte brevius bi-impressa, genis vix inflatis, oculis convexiori- 

 bus, hemisphasricus ; thorace lateribus minus rotundato, pone medium 

 longe minus profunde sinuato, angulis posticis exacte rectis extus sub- 

 reflexis, margine laterali antice angustiore, basi utrinque bifoveolata, 

 foveola exteriore minuta. Elytra baud aliter punctata foveolataque, 

 interstitiis plus minusve convexis, nullo vero costato, septimo sub- 

 elevato.

74. T. prolixus, n.s. Elongate, narrow, sub-parallel, sub-de- 

 pressed, of a glossy black colour tinged with red, the antennce palpi 

 and tarsi pitchy-red. Head moderately elongate, a little constricted 

 behind the eyes, with an irregularly formed H-like impression in 

 front ; eyes rather large ; palpi elongate. Prothorax quadrate-cordate, 

 widest in front of the middle, a little emarginated in front, with 

 rounded angles ; the sides are rounded, and sinuously narrowed 

 behind, the base is a little hollowed in the middle, with rectangular 

 angles ; it is slightly convex, with a well-marked dorsal line, a frontal 

 depression on the middle and one near each angle, the basal fovese are 

 well-defined and elongate and broadest at the hind margin, the rest of
