Found in *' rotting wood." 



This species was described from specimens from Siam and Ceylon. 

 It probably is widely distributed throughout the Oriental region. 

 There are in the British Museum collection examples from China 

 and Kew Gruinea which agree with those found in Christmas 

 Island. 



Family BRENTHIDJE. 

 73. Orychodes andrewsi, Gahan, sp.n. 



^. Rostro supra basi sulcato ; capite postice bituberculato, 

 utrinque vix pone oculum dentate, dente sat recte transversa, ultra 

 oculum pauUo projiciente ; prothorace rufo-castaneo, polito, quam 

 latitudine maxim o fere duplo longiore, apice quam basi latiore, 

 ad basin transversim bisulcato, et ante sulcos linea mediana leviter 

 impresso ; elytris quam pronoto quarta parte longioribus, rufo- 

 brunneis, lineis flavis interruptis, ornatis, longitudinaliter striatis, 

 striis intermediis versus medium plus minusve obsoletis. 



5. Capite breviore, postice hand tuberculato, rostro simplice, 

 nee dentate nee ad apicem dilatato; prothorace quam latiore 

 dimidio parte longiore. 



Long, (rostro inch) 13-21 mm. 



^ . Kostrum grooved above at the base ; anterior part with two 

 rows of teeth; head with two backwardly projecting and slightly 

 diverging tubercles behind, and at each of the post-ocular angles 

 with a rather sharp tooth which projects outwards to a level with 

 or even a little beyond the outermost portion of the eye. Antennae, 

 when turned forwards, reaching beyond the apex of the rostrum by 

 less than half their length. "When they are pressed close to the 

 rostrum it will be seen that the sixth joint does not extend beyond 

 the apex of the rostrum. Prothorax about three-quarters of the 

 length of the elytra, and nearly twice as long as its own greatest 

 breadth ; it is a little broader across the apex than at the base ; at 

 the base it is constricted and marked with two transverse grooves, 

 from the anterior of which a faintly impressed median line 

 extends as far as the middle. Elytra reddish-brown, marked with 

 interrupted yellow lines, these lines, which do not offer so strong 

 a contrast with the general colour of the elytra as in allied species, 

 being arranged as folloAvs : — One on the second interstice, which is 

 yellow at the base and on the posterior declivity ; one on the third 

 interstice, which is yellow at the base and in front of and behind 

 the middle, as well as on the posterior declivity ; fourth interstice 

 similar to the third, but with the yellow parts shorter and less 

 •distinct ; fifth yellow at base, behind the middle, and near the
