is bifid, and armed at its inner surface with an obsolete tooth. The 

 posterior femora are incrassated. The tibia (Tab. TV. fig. 4g) is 

 short, inflected at its immediate base, and gradually thickened to- 

 wards the apex ; when viewed from behind, the posterior surface is 

 slightly grooved longitudinally, simple (not sinuate or armed with a 

 spur) ; the apex is obliquely truncate and simple at the extremity, 

 without any terminal claws. The tarsi (Tab. IV. fig. 4 h) are at- 

 tenuate and short ; the first and second joints subequal ; the third 

 shorter and circular; the apical joint is broadly inflated at its ex- 

 tremity. 



This genus is distinguishable from all others (except Hydmosyne) 

 by its robust, subparallel and ovate form, depressed (not cylindrical), 

 by the breadth of its thorax, and by its unarmed posterior tibia? ; from 

 Oinops it may be separated by its less porrect head, by the structure 

 of its maxillary palpi, and also by its unarmed tibia?. The species 

 composing it will probably, hereafter, be subdivided into two separate 

 genera. There is a manifest contrast in facies between E. prceclara 

 and the two other species : the former insect is distinctly oval, the 

 humeral angles of the elytra are less prominent, and the lateral line 

 of the thorax is almost continued in the line of margination of the 

 elytra ; in E. scabrosa the shoulders are prominent, the sides of the 

 elytra are more parallel, and the thorax is less broadly transverse ; 

 the ultimate joint of the anterior tarsus is also, in the former species, 

 more deeply bilobed.

Long. corp. 3 J lin., lat. 1| lin. 



Oblong, oval, robust, shining. Head transverse, short, depressed, 

 much narrower than the thorax ; eyes small, prominent, not extend- 

 ing to the anterior margin of the thorax ; above the base of the 

 antennae is a transverse ridge (rendered more distinct by a medial 

 depression behind it) ; surface of the head punctate, rufous. Thorax 

 transverse, equate ; the anterior angles (which project beyond the 

 head) are subacute and depressed ; the sides marginate ; the basal 

 angles are in close proximity to the shoulder of the elytra ; the form 

 of the thorax (broad at the base) is gradually constricted towards 

 the anterior ringles. ;i]though even at the apex it is considerably
