Hab. in Africa sequinoxiali. Mus. Soc. Linn. Lond. D. Banks. 



Caput nigrum, sub lente tenuissirae punctatum carina longitudinali 

 utrinque versus marginem internum oculorum. Antenna articulis 

 apicalibus latioribus. Pronotum transverse quadratum, angulis an- 

 ticis oblique truncatis et parum rotundatis, lateribus in medio sinu- 

 atis tenuissime marginatis, angulis posticis acutis fere rectangulis ; 

 sub lente tenuissime punctatum ; lateribus late et obscure sanguineis, 

 colore sanguineo ante medium intus acute producto, dorso nigro ; 

 margine postico in medio versus scutellum parum producto. Elytra 

 nigra nitida laevia, latiora quam in congenericis, prsesertim pone me- 

 dium, apicem versus attenuata ; sub lente seriebus 8 longitudinalibus 

 punctorum minutorum. Pedes longitudine mediocres, graciles, tibiis 

 simplicibus fere rectis. 



Individuum in mus. D. Hope vidi lineas 9^ tantum habens, statu- 

 raque parum minus robusta ; vix tamen species distincta. 



Nyctobates punctatus. Nyct. niger obscurus, prothoracis angulis 

 anticis rotundatis, lateribus in medio incisis angulisque posticis 

 acutis, elytris punctato-striatis, antennis sensim dilatatis. 



Long. corp. lin. 9| ; lat. elytr. pone med. lin. fere 4. 



Hab. in Guinea. In mus. D. Hope, comm. D. Westermann. 



Syn. Helops punctatus, Fabr., Syst. Eleuth. i. 161. 



Caput obscurum sub lente tenue punctatum ; clypeo postice im- 

 pressione transversa e vertice separato, carinaque utrinque ad mar- 

 ginem oculorum. Antenna mediocres sensim ad apicem incrassatae 

 compressse, linea tenui media impressa postica. Prothorax subqua- 

 dratus angulis anticis rotundatis, lateribus in medio sinuatis, tenue 

 marginatis, angulis posticis acutis et parum extus productis ; margine 

 postico versus scutellum postice producto. Elytra thorace baud 

 multo latiora pone medium parum latiora, singulo seriebus 8 longi- 

 tudinalibus punctorum impressorum magnitudine irregularium, stria- 

 que altera abbreviate versus scutellum ; striis 1 et 2 ad basin con- 

 nexis ; striae 5 et 6 longe ante apicem conjunguntur ; striae 3 et 4 

 propiores, 2 et 7, et 1 : cum 8va connexis. Pedes longitudine me- 

 diocres, tibiis simplicibus et fere rectis. Mesosternum antice biden- 

 tatum, prosterni apicem acutum recipiens. 



I give the insect here described as the true H. punctatus, Fab., on 

 the authority of a specimen received by the Rev. F. W. Hope from 

 Copenhagen, from M. Westermann, who has such excellent oppor- 

 tunities of determining those Fabrician species which were described 

 from the cabinets of Lund and Sehestedt, as was the case with the 

 present species. This is the more important, as the Fabrician de- 

 scription is so slight as to be applicable to scores of species of He- 

 teromerous insects. 



Nyctobates Hypocrita. Nyct. niger subobscurus tenuissime punc- 

 tatus, prothoracis lateribus subrotundatis integris angulis anticis 

 acutis, antennis longioribus apice parum latioribus. 



Long. corp. lin. 8j; lat. elytr. pone med. lin. 3£.
