olvtron has al)out six lines of a slii^litly y»'llo\vi.sli tint, of 

 Avliich one lios aloiif]: tlie outer margin, the .second seta out 

 just below the shoulder and is continued in a nearly straight 

 direction along the side of the elytron, the third proceeds 

 from the upper part of the shoulder and joins the second a 

 little before the apex; the next two lines are dorsal in 

 position, they are subparallel to one 

 another in the antrrior fourth of the 

 elytron, behind which they rather 

 abruptly converge ; after again diver- 

 ging slightly tliey converge to join 

 one another at about the beginning 

 of the apical fourth, whence they are 

 continued as a single line up to the 

 outer angle of the oblique apical 

 truncature ; the sixth is a very short 

 line passing back from the base. In jd 

 addition to these six linesan ashy-grey ^ Cc ^ 

 streak may be seen along the suture, 



Avith a rather faint and broken white line limiting it on the 

 outer side. The body underneath has a drab pubescence, 

 with dark brown areas. The pro- and mesosterna and the 

 lower part of the sides of the prothorax are almost black in 

 colour. The legs and antennae are covered with a nearly 

 uniform drab-coloured pubescence ; but in some examples the 

 intermediate joints of the antennai are more or less dark 

 brown towards the tip. The front of the head is also in some 

 examples of a dark brown or nearly black colour ; but this is 

 partly due to the rubbing away of the pubescence. 



Four examples of this species are now in the British 

 ]\Iuseum collection ; they were all taken alive in England 

 upon imported orchids. One was presented by the late 

 !RIr. J. C Bowring, who found it in his conservatory; two 

 were sent by ]\lr, M'Lachlan, with the information that they 

 ■were certainly imported with Dendrohium yiobile and were 

 playing havoc with the leaves and pseudobulbs of some plants 

 of this species; a fourth specimen, recently presented by 

 Sir Archibald Buchan-Hepburn, was found upon the flower 

 of Dendrohium atropurjmreum. 



There are examples also in the museum of the Hon. Walter 

 Rothschild at Tring ; these were likewise found on orchids of 

 the species Dendrohium nohile, which. Dr. Jordan informs 

 me, "were imported from Moulmein. The areas of known 

 distribution of the two species of Dendrohium mentioned 

 aiipear to overlap only in Burma ; so I think I am quite 

 iustitied in assigning Burma as the habitat of the new species 

 of Diaxenes.
