Elytra shorter and broader than the thorax, transverse, closely 

 covered with short longitudinal granules, except at the pos- 

 terior margin and epipleiirap which are without sculpture. 

 Abdomen with a few setiferous punctures along the posterior 

 margins of the segments otherwise without sculpture or 

 pubescence. 



Mt. Dulit, 3500 feet above the sea, a single specimen. 



Myrmedonl\ borneensis n. sp. 



Very shining ; head black ; thorax pitchy-brown the sides 

 lighter; elytra pitchy, the base and disc more or less pitchy- 

 testaceous ; abdomen pitchy-testaceous the posterior margins 

 of the segments and the apex more or less testaceous. 

 Antennae black, the 1st joint pitchy or pitchy-testaceous, 2nd 

 testaceous. Legs testaceous. Length 5 mm. 



Of the build of M. seiniflava Bernli., but larger and more 

 robust, the colour of the abdomen more obscure, the antennse 

 longer and less stout, the puncturation of the thorax a little 

 finer, that of the elytra finer and more asperate. Head 

 transverse a little narrower than the thorax, black, shining, 

 the middle of the disc impressed, umbonate between the 

 antennal tubercles, very finely, sparingly punctured especially 

 in front, finely shagreened. Antenntp with the 1st joint long 

 and thickened apically, 2nd much shorter, 3rd longer than 

 2nd, 4th to 6th a little longer than broad, gradually decreasing" 

 in length, 7th and 8th about as long as broad, 9th and lOtli 

 transverse, 11th as long as the two preceding together. Thorax 

 a little broader than long, widest at the rounded anterior 

 angles, nearly straightly, narrowed behind to the posterior 

 angles which are furnished witli a small sharp tooth ; middle 

 of the disc broadly and deeply impressed, especially behind, 

 along the sides likewise broadly but less deeply impressed, 

 very finely and very sparingly punctured and without ground 

 sculpture. Elytra scarcely longer but broader than the thorax, 

 scarcely transverse, closely, moderately finely punctured. 

 Abdomen practically impunctate on the disc, very finely 

 transversely strigose. 



(f . 7th dorsal segment in the middle with a transverse row 

 of 4 minute granules ; before the posterior border with 4 

 small granules, of which the median pair are occasionally 

 united to form a larger tubercle. 8th dorsal segment crescen-
