COLEOPTERA. 3l 
maxillaries is elongated. The outer side of the two anterior tibiz 
presents two teeth. 
Puatyeenta, MacLl. 
The body much flattened; thorax almost cordiform and widely 
truncated at both ends; maxille terminated by a pencil of hairs, the 
internal lobe triangular and emarginate at the end; last joint of the 
palpi ovoido-cylindrical; mentum almost square, emarginated in the 
middle of its superior edge, and slightly on the sides; inner sides of 
the posterior tibiz densely pilose*. In 
CreMAsTocHEiLus, ACnoch, 
The thorax nearly forms a transversal square; the maxille are 
terminated by a strong hooked or falciform tooth, with sete or little 
spines in lieu of an inner lobe; the last joint of the palpi is very long 
and cylindrical; and the mentum in the form of a widened heart, or 
of a reversed triangle, with its superior angles rounded and without 
-any sensible emargination f. 
There, the mentum.is in the form of a much widened heart, with- 
out a discoidal cavity, and its superior margin emarginate or sinuous. 
The anterior extremity of the epistoma, in the males, is divided into 
two lobes, in the form of truncated or obtuse horns. The thorax is 
nearly orbicular. 
Gouatu, Lam. Kirb.—Ceronia, Fab. Oliv. 
A subgenus which, according to M. de Lamarck, is composed of 
large and beautiful species, some of which inhabit Africa and the 
East Indies, and the others, tropical America. Messrs. Lepeletier 
and Serville—Encyc. Meéthod., article Scarabéides—have separated 
the latter from it under the generic appellation of Inca. The epi- 
mera is not prominent. The inner sides of the thighs of the two 
anterior legs are furnished at base with a tooth and an emargination. 
The middle of the superior margin of the mentum is strongly emar- 
ginated; this part in the true Goliaths presents four lobes or teeth, 
two superior and the two others lateral. The labial palpi are in- 
serted on its edges in the emarginations of these latter lobes. All 
the known species are large; but M. Verreaux, Jun., the nephew

+ Lat., Gener. Crust. et Insect., p. 121. M. Dupont, naturalist to the Duke of 
Orleans, whose collection of Coleopterous Insects, next to that of Count Dejean, is 
the most extensive in Paris, has received from Lamana—French Guiana—an Insect 
presenting all the essential characters of a Cremastocbeilus, but in which the epi- 
mera or axillary pieces are more apparent when the animal is viewed from above. 
The anterior tibie are arcuated, and have a strong dentiform projection on the inner 
side. All the tarsi are short, thick, cylindrical, and terminated by two very long 
hooks. The anterior extremity of the epistoma is turned up in the manner of an 
almost square blade. The posterior extremity of the head presents an elevation 
divided into two teeth or tubercles. The Insect is about an inch long, black, with a 
red spot on each elytron. 
The Cetonia elongata, of Olivier, appears to be a Cremastocheilus.
