Very like A. dejeani, but differing as follows:—Rostrum slightly longer, more deeply hollowed down the 
middle, appearing rather sharply carinate on each side above; the antennal club more elongate; the 
elytra relatively longer, with similarly coloured scales, the bare spots on the interstices extremely small 
in 9, larger, numerous, and conspicuous in d¢, the suture set with long hairs towards the tip in @ ; the 
tibiee and tarsi often ferruginous. 
Length 73-10, breadth 23-4 millim. (d Q.)

This insect is apparently common in the Los Altos region of Guatemala (between 
6000 and 9000 feet) and it has long been known under Jekel’s MS. name of 
H. scintillans. ‘The scales are coloured and beautifully scintillate as in H. dejeani, 
from which the present species is separable by the more deeply excavate rostrum and 
the longer antennal club. Four specimens only have been seen from Mexico, and the 
* Possibly found by Scherzer, who collected also in the Los Altos region of Guatemala.
