is most raised ; thence to the apical third it is moderately elevated, 

 but beyond that point it is depressed ; the fifth interstice is de- 

 pressed on the basal third of the elytra, then raised in the middle, 

 and towards the apex of the elytron it is produced into a much- 

 elevated oblong tubercle, as is also the first interstice nearly at 

 the same point, so that the elytra present four sub-apical tubercles, 

 of which the outermost pair are rather the larger, and the inner- 

 most pair a little more remote from the apex ; at the base, the 

 inner half of each elytron is produced anteriorly into a lobe, which 

 is much incrassated, particularly on the outer side, where it forms 

 a conspicuous tubercle ; the humeral angle is also incrassated and 

 raised, but to a smaller degree. With regard to the colouring, 

 the scales which cover the legs and under parts of the body are 

 of a tolerably uniform pale brownish-ochre colour.; the upper 

 parts of the body are variegated with similarly coloured scales 

 and others of a dark brown ; on the elytra the paler scales pre- 

 dominate on the disc, but in the region of the shoulders, the sides 

 of the elytra, and the sub-apical portion, the darker colour 

 prevails : all the tubercles are dark.

In size and form this insect nearly resembles the small Euro- 

 pean Lixus, known as the L. rufitarsis of Schonherr : in colour it 

 is of a somewhat deeper red than the Jpion frumentarium. 

 Although only certain parts of the body appear to be clothed with 

 scales (these being of a yellow colour), 1 find, upon placing the 

 insect under a microscope, that the apparently denuded parts are 

 covered with scales of the same rounded form as the yellow ones, 

 but agreeing perfectly in colour with the parts they cover. 

 Antennae ferruginous, with scattered pale scales on the scape. 

 Rostrum rather longer than the head, cylindrical and moderately 

 curved ; the antennal groove, lateral and commencing near the 

 middle of the rostrum, runs obliquely backwards and downwards 

 to the lower angle of the eye ; when retracted the scape of the 

 antennae lies completely in the groove ; the surface of the rostrum 

 presents distinct scattered punctures, and, excepting at the apex, 

 is clothed with yellow scales. Head punctured, and clothed with
