wliole distance between tlie biutl coxa3 ; on eitlier side of tlie 

 impres.sioii the segment is rai.sed into a ridge which bears 

 rather long pubescence. 



(iii.) R. aquUi.nus^ sp. n._, (^ : a marked longitudinal irn- 

 pressionj broadening behind, along- the posterior | of the 

 inetasteriiuin, the pubescence in the iinpressiDU being mucli 

 closer tiian on either side of it ; first abdominal segment with 

 no im|nession, but with a little median group of hairs.

Long. Corp. 0"85 mm. 



OutHne sliown in fig. 37 ; the thorax appears a little 

 .shorter than it actually is, owing to its being bent down ; 

 length of the elytra very nearly equal to their combined 

 breadth, which is greatest a little before the middle. Body 

 above shining, glabrous ; finely and closely alutaceous above 

 and beneathr Colour', thorax reddish yellow, elytra dark 

 castaneous brown, in the type-specimen lighter and more 

 reddish in the posterior half near the suture ; ventral surface 

 castaneous brown, antennae and legs yellowish, clubs of the 

 antennce not blackened. Antennie (fig. 38)^ a little longer 

 than the wiiith of the head from eye to eye. Thorax nar- 

 rowly niargined at the sides, with base very shallowly 

 sinuate on eitlier side of the middle, and hind angles (seen 

 from the side) slightly less than right angles; surface im- 

 ])Unctate. Scutdlani rounded. Elytra wdth lateral margins 

 narrowly reflexed, but in viewing a specimen from vertically 

 above the margins are oidy visible behind the shoulder and 

 again for a short s))ace behind the middle ; sutural stria 

 quite absent; surface with fine double punctures, each con- 

 sisting of two slightly elongated punctures lying close side 

 by side*; in a transverse direction the double punctures are 

 about their own diameter apart, but in a longitudinal direc- 

 tion about twice this distance. Wings: no trace of these 



* The alutaceous surface and double punctures are cbaracteristic of a 

 number of other numbers of the genus.
