APALOTEITJS. 1 67 



gin of the eyes, robust, filiform ; the first joint is elongate and 

 broadly dilated ; the second ovate, short ; the third, fourth and fifth 

 attenuated and subequal. 



Eyes globose, distant, situated almost immediately at the base of 

 the head, extending laterally not so far as the anterior angles of tho 

 thorax. 



Head short, hardly produced in front, deflected at right angles to 

 the plane of the elytra. 



Thorax broader than the head, transverse, very slightly con- 

 stricted in front ; the anterior angles subacute and depressed ; the 

 sides marginate; the surface equate, and in A. pubescens finely 

 pubescent. 



Scutellum large, triangular, impunctate, situated on the plane of 

 the elytra. 



Elytra broad, robust, subcylindrical, rounded at the apex ; in A. 

 pubescens deeply punctate-striate and pubescent. 



Legs : the anterior femora sufficiently robust, attenuated at the 

 base. The tibia? are straight, incurved at their immediate base, and 

 cylindrical. The tarsi are short ; the basal joint triangular, of the 

 breadth of the base of the tibia ; the second of the same form, but 

 more minute ; the third transverse, subcircular at the apex, distinctly 

 bilobed ; these three are clothed on their under side with thick rigid 

 pubescence ; from the base of the third proceeds the last joint, which 

 is elongated, and gradually dilated and incurved towards the apex ; 

 the joint terminates in a bifid tooth, unarmed by any spur on its 

 inner surface. The posterior femora are broadly incrassated, ovate, 

 tapering gradually to the apex, which is obliquely truncate. The 

 tibia (Tab. VII. fig. 1 g) is short, abruptly incurved at its immediate 

 base ; the posterior surface is longitudinally grooved, and terminates 

 in a hollowed socket for the insertion of the tarsus ; the margination 

 of this socket is armed above the insertion of the tarsus, and also 

 below, with an obtuse spur. The tarsus is abbreviated ; the first and 

 second joints attenuated at the base, the second being more minute 

 than the first ; the third minute and circular ; the fourth dilated into 

 a globular inflation, which conceals from above the terminal claw. 



I am unable, from the examples before me, to trace with certainty 

 any sexual distinctions in this genus. 



Apalotrius is in form closely related to Oetogonotes, from which it 

 may be separated by the quadrangular (not hexagonal) form of its 

 thorax, by the manifestly different form of the maxillary palpi, and 

 by the distinct spur on the margination of the postical tibia.
