Longicornia from Africa and Madagascar. 323 



pedibusque sequaliter pubescentibus ; antennis griseis, articulis a 

 tertio apicibus fiiscis. Long. 16 ; lat. 7 mm. 



Hah. I. of Johanna. 



Derm olive-green, clothed with a dense pale fulvous pubescence. 

 Head very sparsely punctured with the punctures almost entirely 

 concealed by the pubescence. Prothorax with the pubescence 

 thick and uniform in front and behind, and interrupted across 

 the middle of the disk by numerous strong and somewhat asperate 

 punctures. Scutellum transverse, truncate behind. Elytra strongly 

 and rather thickly punctured, with the punctures stronger and 

 somewhat asperate towards the base ; with the pale fulvous pubes- 

 cence, owing to the somewhat irregular distribution of the punc- 

 tures, denser in some places than others ; with three or four 

 very obscure rust-brown spots or bands on each elytron. Body 

 underneath and legs with a nearly uniform fulvous grey pubes- 

 cence. Antennae scarcely longer than the body (<? ). 



This species has the size and general form of E. 

 sparsus, King., with the sides of the prothorax a Httle 

 more strongly tubercled. It may be easily distinguished 

 by its difference of colom' and punctuation. 



SoRiDus, n. g. 



Head broadly and slightly concave between the antennal 

 tubercles ; front transverse ; eyes subdivided, lower lobes small. 

 AntennfE a little longer than the body, with the scape rather 

 short and stout, the remaining joints slender, with joints 3 and 

 4 subequal, each much longer than the scape ; the fifth a little 

 longer than the scape, the rest slightly and gradually decreasing 

 in length. Prothorax longer than broad, unarmed at the sides, 

 with its greatest width at about the anterior third, and from 

 thence gradually narrowed anteriorly and posteriorly ; with the 

 pronotum produced and rounded in front. Elytra at the base a 

 little broader than the prothorax ; posteriorly scarcely narrowed ; 

 broadly sub-truncate at the apex. Intermediate tibiae entire ; 

 claws of the tarsi divergent. Prosternal process simple, rather 

 narrow in front, dilated posteriorly. Mesosternal process with an 

 obtuse tubercle near the middle of its length. Anterior cotyloid 

 cavities placed far enough back from the anterior border of the 

 prothorax, slightly angulate on the outside. Intermediate cotyloid 

 cavities open on the outside. 



The species on which this genus is founded must be 

 withdrawn from Xylorrhiza to which it has little reseni-
