BoTDRiDERES [Colydiicte]. 

 Erichson, Naturg. der Ins. Deutschl. iii. p. 288. 



Bothn'deres? rhysodoldes. (PL III. fig. H.) 

 B. ? elongatus, castaneus, nitidus ; prothorace lateribus poatice aiigulatis, 

 disco profunde lonp-itudiiialiter excavato, basi canaliculato ; elytris 

 ovato-oblongis, singulo (piinquecostato, costa secunda abbreviata. 

 Hub. New Guinea (l)orey). 



NaiTowly elongate, chestnut-brown, shining ; head shortly ovate, very 

 convex in front, minutely punctured ; eyes large, round, rather promi- 

 nent ; antenna3 scarcely longer than the head, the club a little longer 

 than broad, the last joint nearly as large as the preceding one ; pro- 

 thorax rather elongate, the anterior angles produced, the sides rounded, 

 but considerably contracted posteriorly, the disk with a deep ovoid 

 longitudinal impression extending its whole length except a little in 

 front, but which is narrower posteriorly, (there is a very faint trace of 

 a raised central line or space) ; scutellum punctiform ; elj'tra narrowly 

 ovate, the shoulders a little produced, the base wider than the pro- 

 thorax at its junction, each vdth five costae, the first sutural, moderately 

 raised, the second extending to only about a third the length of the 

 elytron, the remainder very strongly elevated, punctation nearly obso- 

 lete 5 body beneath smooth, shining, impunctate; legs moderately long, 

 tibife of the anterior and intermediate pairs slightly serrated externally ; 

 tai-si about half the length of the tibiae. Length 3 lines. 



Resembles a Rhysodes in habit. As the specimen now before me 

 is unique, I must, without an examination of its trophi, satisfy myself 

 with referring it to Bothmderes. 



Bothrideres? noeturnus. (PI. III. fig. 12.) 



B. ? elongato-ovatus, robustus, castaneus, nitidus ; prothorace disco linea 

 parallelogrammum includente impressa ; elytiis profmide striato-punc- 

 tatis; antennarum articulo ultimo prsecedente majore. 



Hah. New Guinea (Dorey). 



Elongate-ovate, reddish-chestnut, shining ; head considerably ex- 

 serted, hollowed out between the eyes, thinly punctured, the lip nearly 

 hidden by the clypeus ; antennae not longer than the head, the terminal 

 joint larger in every way than the preceding one ; eyes large, very pro- 

 minent ; prothorax scarcely longer than wide, the anterior angles pro- 

 minent, but not projecting, the sides rounded, much contracted and 

 sinuate at the base, with a deep fovea on each side near the angle, the 

 disk covered with very small distant punctures, and having in its 

 centre a deeply impressed line including a parallelogranmiical space ; 

 scutellum nearly punctiform; elytra rounded at the sides, the base 

 slightly contracted, but much broader than the prothorax at its junc- 

 tion, striato-punctate, the interstices scarcely raised, except the tliird
