shiny, and occasionally with short depressed apical setse, the inter- 

 spaces with uniform brown scaling. Legs with sparser pale scaling 

 forming a denser ring near apex of femora ; posterior tarsi narrow, 

 setose, the three basal joints of the same width, 2nd and 3rd sub- 

 equal in length, 1st longei-. 



Cape Coloxy. 



Type in the British Museum. 



The peculiar structure of the prothorax will differentiate 

 trlcostatus fi-om every other species in the genus.

Long. 14-16, lat. 5^-7 mm. 



Head convex, with indistmct punctuation and dense brown 

 scaling, forehead with a faint impression ; anteocular furrows 

 distinct. Rostrum not incised at base, as long as head and 

 pi'othorax, thick, strongly curved and dilated towards apex. 

 Upper sui'face obscurely punctured and with dense brown scaling, 

 the structure variable ; in the typical form there is a deej) and 

 continuous central f uri-ow, but this vaiies much in depth and in 

 some examples it disappears almost entii'ely ; lateral sulci not 

 very deep, not uniting at base, subequal in length, the lower paii- 

 being rather shallower ; scrobes deep, dii-ected beneath base of 

 I'ostrum ; inferior basal furrow absent. Antennce squamose, the 

 scape not I'eaching eye ; the fii-st joint of funicle slightly longer 

 than second. Prothorax rather transverse, the length greater 

 than the width at base, which is equal to apex, sides strongly 

 I'ounded, broadest about middle, dorsal anterior margin distinctly 

 convex, ocular lobes well developed. Upper surface convex, ii-re- 

 gvilarly set with large elevated tubercles, leaving a broad central 

 furrow containing a distinct narrow carina, the tubercles adjoining 

 the central furrow often subci-istate ; tubercles and interstices 

 entirely covered with brown scaling, the former with short thick 

 white depressed setae. Elytra oblongo-ovate, rather narrower 

 in (S , shoulders subrectangulai-, sides scarcely rounded, apical 

 processes veiy short and conical in both sexes. Upper surface 

 convex, with rows of large indistinct punctures, separated by 

 scale-covei'ed granules ; interval 1 with a row of gi'anules dis- 

 appearing behind ; interval 2 usually with only a shoi't subcristate 

 row of conical tubercles from middle, or behind middle, to apex, 

 but sometimes there are small tubercles almost up to the base ; 

 intervij,l 3 with a row of closely-set conical tubercles, which is 

 iisually broadly intei-rupted on the declivity, but is occasionally 

 continuous ; intervals 4 and 6 quite plane ; 5 and 7 with complete 

 rows of elevated conical tubei'cles ; the exti-eme apices only of 

 tubercles bare and each with a short thick depressed white seta, 

 the rest of the surface densely covered with uniform brown scaling. 

 Legs with dense greyish squam?e ; posterior tarsi with the joints of 

 the same width, 2nd and 3rd subequal in length, 1st rather longer.
