49. In the Zoologisches Magazin, Band 2, Stuck 1, published in 1823, M. Wiedemann 
described a Javanese insect under the name of Goliathus rhinophyllus. As such the insect 
appears in Dejean’s Catalogue ; and I confess that when I first saw the species many years ago 
in the collection of M. Bose, at Paris, I also considered it to belong to the sub-genus 
Goliathus. In the monograph of MM. Gory and Percheron, however, the insect is called 
“ Macronata rhynophylla,” and Wiedemann is erroneously cited as the authority for this 
double barbarism. These French naturalists are so far right in assigning our insect to the 
sub-genus Macronota of Wiedemann, that it certainly comes much nearer to this groupe than to 
Goliathus. M. Latreille seems, nevertheless, to have been the first who observed that it was not 
a Goliathus. From this sub-genus it differs in the long corneous part of the mandibles, in the 
maxillae being armed with corneous teeth, in the mentum being very slightly emarginate, and 
in various other particulars, so important as to prove to us that the obvious relation which this 
Javanese insect bears to Goliathus is nothing more than one of analogy ; and on account of 
this analogy I have assigned the species to the 
Sub-genus 1. Philistina, M‘L. 
Antenna of ten joints, the scape being long and obconical, the second joint globose, larger 
than the remainder, the three joints excepted that compose the long pear-shaped clava. 
Labrum membranaceous, emarginate. 
Mandibles having the corneous part sharp, lanceolate, and twice as long as the square mem- 
branaceous part. 
Maxilla short, prismatic, and terminating in three, if not more, sharp corneous teeth, which 
are covered behind with a long pencil of hairs. 
Maxillary palpi differing in the sexes. 
Labial palpi differing in the sexes. 
Mentum quadrate, truncated in front, and very little emarginate. 
Clypeus produced into a long horn in male, and quadrate in female. Body depressed. 
Thorax much narrower than elytra, and not very much lobed in the middle behind ; 
in the male it is horned. Scutellum large, triangular. Epimeron transversely distinct. 
Mesosternum not produced. Anterior tibia in both sexes externally tridentate, and 
with very long tarsi in the male. Feet with plantula and pseudonychia very distinct. 
Note. As there is only one species known which is the “ Macronata rhynophylla' of Gory, it is very
