MACROMA INSIGNIS. 115 



NOTE VT. 

 ON MACROMA INSIGNIS GESTRO 



(COLEOPTERA : CETONIIDAE) 



C. RITSEMA Cz. 



In a small collection of oriental insects , handed to me 

 for identification by Mr. H. Veen of Haarlem , was a 

 specimen of a large black il/acroma-species , captured by 

 bis brother , Mr. Ed. Veen , on Mount Paugolot in the 

 district Groot Mandheling of the Tapanoeli Residency ,

This specimen agreed admirably well with the descrip-

 Civ. Genova, vol. XXX, p. 852; pi. 2, fig. 10), but as 

 this species was described from a specimen from Burma 

 (Mount Cariani, at an elevation of 1300 — 1400 meter 

 above the level of the sea), I thought it of interest to 

 examine, if possible, the type-specimen. I therefore wrote 

 to Dr. Gestro , who , without delay , sent it to me. 



In comparing the two specimens I found only the fol- 

 lowing, by no means important, differences: 



The Sumatran specimen is somewhat larger , measuring 

 from the anterior margin of the pronotum to the apex of 

 the pygidium 27 mm. instead of 25 mm., and across the 

 shoulders 15 mm. instead of 14 mm. 



In the Sumatran specimen the sculpture (consisting in 

 transverse scratches) along the lateral margins of the 

 apical half of the elytra as well as that on the apical
