Spec. 11. CuginoroNus MacLean. 
Long. lin. 23. Lat. lin. 13. 
ZEneo-viridis ; thorace lateribus externè serrulatis et varioloso-punctatis, sulco 
longitudinali in medio dorso fortiter impresso, elytris nigro-æneis maculis 
croceis insignitis, marginibus externé elevatis. Tan. XL. fig. 3. 
Corpus infrà pilis longis obsitum, femoribus medio viridibus et glabris tibiis- 
que valdé armatis, 
The magnificent insect just described is named in honour of William Sharp 
MacLeay, Esq., author of Hor Entomologicæ ; and I have much pleasure in 
dedicating it to one who has so ably treated of the geography, manners and 
natural affinities of the insects which compose the Linnean genus Scarabæus. 
EucHEIRIDÆ, mihi. 
The above family, according to my views, consists of the following ge- 
nera :— 
Genus. Country. Typical Species. 
1. Eucheirus, Kirby . . East Indies longimanus, Fabricius. 
2. Protomacrus, Newman. . .| Smyrna: bimucronatus, Pallas. 
3. Cheirotonus, Hope. . . .| Assam . . .| MacLeaii, Hope. 
The above three genera are all that are known at present; they are inha-- 
bitants of the Old World, and I do not know any from the New World corre- 
sponding with them, although an anonymous author, who has published an 
account of Venezuela, asserts that the longimanus of Fabricius is found in 
the last-mentioned locality; but from the description of the species, which is 
concisely given by the author, it is evident some other insect than longi- 
manus, Fab. is alluded to, and I think it not improbable, therefore, that 
one of the Golofa or Sawyer Beetles, which abound in Venezuela, has been 
mistaken for the Fabrician insect. To the first of the above-mentioned genera 
the name of Macropus has been attributed, but as that term was previously 
used in other branches of zoology, and is still applied to the Kanguroo Beetle 
described by Dr. Shaw, Mr. Kirby has very properly substituted the name of 
Eucheirus. ts
