192 CARDANUS BOILEAVI. 



a lower level and disappears towards the end ; the disc of 

 each elytron has (besides the sutural interstice) six convex 

 nearly impunctate costae which are separated by a row of 

 umbilicate punctures ; in the first row (that between the 

 sutural interstice and the first costa) these punctures are 

 confluent, in the following rows the punctures are larger 

 and separate. Outside from the 6^^ costa the elytra are 

 covered with more or less regular rows of similar smaller 

 punctures ; the punctuation on the apical portion is larger 

 and somewhat reticulate or confluent ; here and on the 

 sides a few short pale coloured bristles are to be observed. 



The mentum is bilobed ; its anterior half is deeply im- 

 pressed and each lobe has moreover a large deep circular 

 pit, which is smooth at its bottom. — The under surface 

 and legs are sparingly covered with a minute yellowish 

 pubescence. The intermediate tibiae are armed on the outside 

 with five spines of which the superior one is very small ; 

 on the outside of the posterior tibiae only three spines are 

 present. 



A single specimen from Pontianak (West Borneo) in 

 Mr. Rene Oberthiir's collection. 



I have dedicated this species to Mr. H. Boileau, the well 

 known student of Lucanidae.
