266 SPAKNUS. 



Elytra depressed, broad, the length being- not much greater than 

 the breadth ; throughout the surface minute punctures are arranged, 

 which become obsolete near the apex ; the surface is equate, not 

 antemedially depressed, and glabrous. 



Legs robust. The anterior femora cylindrical, and dilated medially. 

 The tibice are straight, incurved at their immediate base. The tarsi 

 are short, the first joint being triangular, in breadth greater than the 

 apex of the tibiae ; the second smaller and more transverse ; the third 

 considerably broader, transversely subcircular, and deeply bilobed ; 

 the apical claw is minute, bifid, and armed at its inner surface near 

 the base with a short and robust claw. The posterior femora are 

 (when seen transversely) very broadly incrassated, ovate, the length 

 being equal to twice the breadth ; distinctly shorter than in the genus 

 Cyrton ; the apex not reaching the apex of the elytra. The tibice 

 are straight, and incurved at their immediate apex ; when seen from 

 behind, the posterior surface is longitudinally grooved and medially 

 slightly compressed ; the margination of this longitudinal groove is 

 simple, not subsinuate ; below the insertion of the tarsus, at the 

 extreme apex, are two robust incurved claws. The tarsi are short 

 and attenuate, the minute terminal claw being completely concealed 

 from above by the globular inflation of the apical joint. 



This genus may be easily recognized by its subrotundate and de- 

 pressed form. Its glabrous surface, in which there is an entire 

 absence of pubescence, separates it at once from Imatium, and its 

 short posterior femora and tibiae amply distingiush it from the genus 

 Cyrton. 



1. Sparnus globosus. (Tab. IX. fig. 4.) 



ft. ovatus, latus, globosus, subdepressns, fulvus, nitidus ; eapite brevi, 

 transverse et longitudinaliter foveolato, impunctato, nigro, ocidis 

 ■lnagnis ; thoracelato, transverso, impunctato, nigro; elytris sub- 

 globosis, brevibus, depressis, subtiliter striato-punctatis, fulvis ; 

 antennis brevibus, ad apicem dilatatis, nigris ; pedibus robustis, 

 nigris. 



Long. corp. 2\ lin., lat. 1^ lin. 



Ovate, broad, globose, subdepressed, impubescent, of a fulvous 

 colour, shining. Head short, depressed (almost vertical), not produced 

 in front ; between the insertion of the antennas are two minute cari- 

 nations extending obliquely upwards to the inner surface of the eyes, 

 rendered more prominent by a medial longitudinal fovea between 

 them, and above them by a transverse fovea (which form together 

 the character of the letter T) ; the eyes are large, and in form globose, 

 lateral, situated at the base of the head j the surface is impunctate
