24 Mr. J. S. Baly on the Eumolpidix?. 



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

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

 above transverse, convex, gTadually thickened and gibbose towards the 

 apex ; surface 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 naiTowed behind, convex ; each elytron with eleven rows of 

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

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

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

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

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

 callus and the suture, is a distinctly I'aised circular piceous protuberance, 

 its circumference bounded by an indistinct circidar 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 aimed 

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

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

 silky hairs. 

 Hab. 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, Spilopyra sumptuosa, Baly. 



This splendid genus, like its near neighbour Podontia, has (juite 

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

 remarks to his ' Monographie des Phytojihages,' having separated 

 the closely allied families of Chrysomelidce. and Eumolpidce by the 

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

 excludes all insects possessing that character from the former. In
