28 COLEOPTERA 



rather prominent. Palpi long and slender ; the maxillary longer than the 

 labial, their terminal joint sub-ovate and acuminate ; the last joint of 

 the labial somewhat obtuse. Labnnn truncate at apex. Head small, 

 sub-triangular, narrowed behind the eyes. Antenna thickened towards 

 the extremity, joints 5 10 cylindric and longer than broad. Prothorax 

 cordiform. Elytra short and broad, convex, a little narrowed behind, 

 the shoulders prominent. Legs slender, the three basal joints of the 

 front tarsi of the male a little dilated ; the first elongate-triangular, the 

 next two almost longer than broad, almost cup-shaped, the terminal 

 elongate but stout, narrower than the penultimate. 



These are the essential characters of the genus ; but Lacordaire's 

 description implies a similar form of the apical joints in both palpi, 

 whereas the labial only are obtuse, the maxillary palpi having the last 

 joint produced to a point. 



59- T. SUlcicOlliS, Bates : Ann. Mag. Nat. Hist., March- 

 April, 1847. E. ellipticus, niger, nitidus; antennis, palpis et pedibus 

 piceo-rufis ; capite spatio inter sulcos laterales haud carinato ; thorace 

 quadrate, vix transverse, medio rotundato, antice plus quam postice 

 angustato, angulis posticis productis rectis, basi utrinque fovea sulci- 

 formi ; elytris conyexis, striato-punctatis.

Resembles the genus Obpterus, but distinguished by the pubescence 

 of the antennae not beginning before the fourth joint, and by the labial 

 palpi having their terminal joint obtuse-ovate, instead of acuminate. 

 Agrees in all essential points with the Chilian genus Tropopterus ; allied 

 to Colpodes, in which the forehead has on each side two grooves with a 

 carinate interval between them. The eighth and ninth striae of the 

 elytra are sunk in a broad groove near the apex ; and the seventh at 

 that part is bordered by a sharp carina. The sixth and seventh striae 

 are nearly obsolete. 



One example, female, sent by Mr. Fereday from Christchurch. 



60. T. seriatoporus, Bates ; Ann. Mag. Nat. Hist., March- 

 April, 1874.^ T. ovatus, elytris gibbosis ; castaneo-rufus, nitidus; 

 thorace basi grosse punctate ; elytris grosse seriatim punctatis. 



Long., 2\ lin. F. 



The labial palpi are obtuse ; the maxillaries taper to a point almost 

 as in Obpterus. The posterior narrowing of the thorax is strongly 

 sinuated, and the hind angles produced ; the whole base is very coarsely 

 punctured ; the dorsal line and long basal foveae are deeply impressed. 

 The sutural rows of punctures are impressed in striae, the rest are super- 

 ficial ; the form of the lateral striae is as in T. sulcicollis. 



Mr. H. Edwards ; one example. 



6 1. T. placens, n.s. Body of a shining pitchy-black colour, 

 legs, palpi, and antennae testaceous. Head with two elongate depres- 

 sions on each side, separated by an elevated interval, the inner depres- 

 sions rather shallow, and united in front by a distinct transverse groove,
