49. Bradymerus seminitidus, Arrow, sp.n. 



Elongatus, fuscus, opacus, palpis, antennis basi tarsisque rufis; 

 capite, cum prothorace punctate rugoso, clypeo crebrius punctato, 

 truncate, antennis clava nigra 6-articulata ; pro thoracis media 

 fertiter sulcato, lateribus integris leviter arcuatis, basi quam 

 humeres minus late, antice vix contracto, angulis omnibus acutis, 

 elytris pallidioribus, nitidis, punctato -striatis, interstitiis carinatis; 

 corpore subtus dense punctato. 



Long. 7-9 mm. 



Allied to B. clathratus, Schauf., and semiasperatus, Fairm., but 

 differing from all closely related species by the almost metallic gloss 

 of the elytra. 



This species was found in large numbers all over the island, 

 although it did not occur in either of the two previous collections. 



50. AlpMtobius piceus, Oliv. : Ent., iii, ^o. 58, p. 17. 



A single specimen was obtained of this species, which is of 

 world-wide distribution. 



51. Palorus depressus, Fab.: Ent. Syst., i, 2, p. 501. 



This insect is also very generally distributed. Two specimens 

 were found. 



52. Toxicum. antilope, Arrow, sp.n. 



Parvum, angustum, ^ capite cornubus 4 retro-curvatis armato, 

 posterioribus fere parallelis sed paullo bisinuatis apice divergentibus 

 antice crinitis, antennae clava 4-articulata, articulis vix transversis ; 

 prothorace subtiliter punctato, ^ valde transverse, 9 subquadrato ; 

 elytris striato-punctatis ; pedibus fuscis. 



Long. 12 mm. 



Allied to T. quadricorne, Eab., but rather smaller, and readily 

 distinguishable from this and all other species hitherto described by 

 the curvature of the posterior horns, which converge from the base^ 

 and slightly diverge towards the tip. 



Several specimens of both sexes were collected. 



53. Nyctobates carbonaria. Arrow, sp.n. 



Parva, nigra, nitida ; capite subtiliter inter oculos minus dense 

 punctato, sutura clypeali distincta, semicirculari ; prothorace parvo 

 transverse, crebre punctato, margine anteriore quam posteriorem 

 angustiore, angulis anticis valde rotundatis, posticis acutis, disca
