476 CLASS INSECTA. 



The tarsi are long, slender, downy, and terminated by two 

 small equal and simple hooks. 



In the antennae and the form of the hood, this sub-genus 

 approximates to Oryctes rather than to Mololontha.* 



Amblyteres. Macleay. 



Have ten articulations in the antennae, the last three of which 

 compose the knob. The labrum is uncovered and lobed. 

 The mandibles are strong and scaly. The maxillary lobe is 

 of middle size, and armed with corneous teeth on the inner 

 side. The middle of the upper extremity of the mentum is 

 a little elongated, truncated, with the angles rounded, and 

 carrying palpi ; their last articulation is ovoid ; the same of 

 the jaws is very much elongated and sub-cylindrical. The 

 scutellum is large.-f- 



In the other sub-genera, of the same division, the mentum 

 is squared transversely, with the middle of the upper edge 

 advanced like a tooth, entire or emarginated. The jaws are 

 entirely corneous, resemble mandibles terminated by a strong 

 tooth, bent, elongated, either entire and very obtuse at the 

 end, or divided at the extremity into two or three points. 

 The mandibles are always scaly and robust. The labrum is 

 exposed. 



Some proper to Australasia have a sternal point, and the 

 hooks of the tarsi entire and unequal. Such are,

j- Macleay, HorcB Entom. I. p. 1. 142. This naturalist does not speak 

 of the hooks of the tarsi, nor of the sexual differences. From the des- 

 cription of the typical species, the corslet was without horns, the fore 

 legs have three teeth on the outer edge ; only two are to be seen on those 

 legs in Pachypus.
