C. RITSKMA 



a Cyclommalus- species, captured by Dr. Beccari on Mount Sin- 

 galang ("West Sumatra), under the specific title elaphus, and now 

 it is not improbable that the magnificent male specimen from Si- 

 Kambé will prove to be the forma maxima of Dr. Gestro's species. 

 I therefore give here the description of the Si-Rambé insect 

 under the name elaphus Gestro, but I propose the name Gestroi 

 for it if future investigations will show the incorrectness of my 

 combination.
