262 IMATIUM. 



claw is bifid, and armed on either side at its base with a short robust 

 spur. The posterior legs are short. The femora (Front, fig. 8/), 

 when viewed laterally, are very broadly incrassated, the breadth 

 being more than hall' the length. The tibice (Front, fig. 8/) are 

 short and almost straight ; when seen from behind, a longitudinal 

 groove from the base to the apex is apparent ; the margination of 

 the groove is simple and straight ; below the insertion of the tarsus 

 the extreme apex is produced into two robust incurved claws. The 

 tarsi (Front, fig. 8 h) are short and attenuate ; the apical claw, 

 which is minute, being almost entirely concealed by the globular 

 inflation of the idtimate joint. 



This genus is remarkable for its short and globular form and its 

 covering of thick pubescence ; it may be separated, prima facie, by 

 these two characters from all other genera in the group. The species 

 composing it are apparently very rare, and found only in the neigh- 

 bourhood of Rio de Janeiro. 



1. Iinatium toinentosum. (Tab. IX. fig. 6.) 



I. globosum, rotundatum, Icevigatum, pube jiava vestitum, rufo-fer- 

 rugineum ; cctjpite brevi, pcene verticali ; thorace transverso, ad 

 latera obsolete marginato, antice subcontracto ; elytris subspheericis, 

 brevibus, striato-punctatis, ad apicem flavo-pmbescentibus ; an- 

 tennis brevibus, incrassatis, art. 1-4 ferrugineis, 5-11 nigris ; 

 pedibus rufo-Jlavis, tarsorum aider, art. 1-3 nigris. 



Long. corp. 2\ lin., lat. If lin. 



Subspherical, rotundate, broad, ferrugincous, clothed throughout 

 (but especially at the margins) with a fine silken yellow pubescence. 

 Head small, very depressed, almost entirely vertical ; labium dark 

 ferrugincous : surface below the insertion of the antennas subcom- 

 planate ; the antennae are approximate ; above the insertion of the 

 antenna) and between the eyes is a medial longitudinal fovea : the 

 eyes are small, situated at quite the base of the head, not extending 

 laterally so far as the anterior angles of the thorax ; the surface is 

 coarsely granulated. Thorax transverse, depressed; the sides are 

 obsoletehj marginate and subcontracted towards the front ; the basal 

 line is angulated at the scutellum ; the surface is rugose and granu- 

 lated. Scutellum slightly elongate, subcordiform, impunctate. Elytra 

 very broad, subspherical, short, with rows of coarse and shallow 

 punctures arranged in the form of stria?, but almost concealed at the 

 sides and near the apex by flavous pubescence. Antennae; much shorter 

 than the elytra, incrassated, robust; the first joint long, broadly di- 

 lated at the apex; the second short, ovate; the third and fourth
