joints obscure fulvous. Thorax rather longer than broad; sides pro- 

 duced mid angled just behind their middle, their hinder portion sinuate ; 

 above transverse, convex, gradually thickened and gibbose towards the 

 apex : sui face deeply rugose-punctate, interstices irregularly thickened ; 

 gibbose portion nearly impunctate. Scutellum subtrigonate. Elytra 

 much broader at the base than the thorax, nearly three times the length, 

 slightly narrowed behind, convex; each elytron with eleven rows of 

 distinct punctate striae, the first abbreviated; on the posterior half 

 of the elytra nearly all the stria' become obsolete, whilst on the epi- 

 pleura are two short additional rows, making the total number across 

 that portion of the surface thirteen ; humeral callus elevated into a 

 short compressed ridge; on the basilar space, between the humeral 

 callus and tin 'suture, is a distinctly raised circular piceous protuberance, 

 its circumference bounded by an indistinct circular groove, the surface 

 of the protuberance smooth and shining, impunctate. Body beneath 

 obscure nigro-piceous ; legs piceous, elongate, basal half of thighs 

 slender, filiform, apical half flask-shaped, two posterior pairs armed 

 towards their apex beneath with a tine acute tooth, basal half of the 

 same thighs obscure fulvous ; all the legs sparingly covered with long 

 silky hairs. 

 Hah. Borneo. 



This insect, most remarkable from its slender, spider-like legs, 

 has been sent in some abundance from the above-mentioned locality 

 by Mr. Wallace.

Type, SpUopyra sumptuosa, Baly. 



This splendid genus, like its near neighbour Fodontia, has quite 

 the habit of a Chrysomela ; but M. Lacordaire, in the introductory 

 remarks to his • Monographic des Phytqphages,' having separated 



the closely allied families of Chrysomelidce and Eumolpidce by the 

 deeply bilobed third joint of the tarsi in the latter group, rigidly 

 exclude^ all insects possessing that character from the former. In
