Boruriverss [ Colydide }. 
Erichson, Naturg. der Ins. Deutschl. ii. p. 288. 
Bothrideres? rhysodoides. (P1. III. fig. 11.) 
B.? elongatus, castaneus, nitidus; prothorace lateribus postice angulatis, 
disco profunde longitudinaliter excavato, basi canaliculato; elytris 
ovato-oblongis, singulo quinquecostato, costa secunda abbreviata. 
Hab. New Guinea (Dorey). 
Narrowly elongate, chestnut-brown, shining; head shortly ovate, very 
convex in front, minutely punctured ; eyes large, round, rather promi- 
nent; antennz 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 ; elytra narrowly 
ovate, the shoulders a little produced, the base wider than the pro- 
thorax at its junction, each with five coste, 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; body beneath smooth, shining, impunctate; legs moderately long, 
tibie of the anterior and intermediate pairs slightly serrated externally ; 
tarsi about half the length of the tibize. 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 Bothrideres. 
Bothrideres? nocturnus. (Pl. III. fig. 12.) 
B.? elongato-ovatus, robustus, castaneus, nitidus ; prothorace disco linea 
parallelogrammum includente impressa ; elytris profunde striato-punc- 
tatis ; antennarum articulo ultimo preecedente majore. 
Hab. 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; antenne 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 parallelogrammical space ; 
seutellum 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 third
