CORYNODES FRATERNUS. 25 



latter agree with the author's description , with the ex- 

 ception that the broadly dilated joints of the anten- 

 nae are not black but purplish blue. The space between 

 the epistome and the trilobate front is covered with dense 

 fulvous pubescence. 



In Mr. Baly's description the thorax is given as one 

 fourth broader than long , in the specimens before me , it 

 is at least twice as broad as long. 



It is therefore possible that the Sumatran specimens 

 represent another species, but I am unable to distinguish 

 it from the author's description sufficiently to come to a 

 definite conclusion, without having seen the type. 



Chrysom,elinae. 



CJu'ijsomela siimatrensis , n. sp. 



Oblong-ovate, convex, metallic greenish black. Thorax 

 subremotely punctured. Elytra fulvous, rather finely and 

 irregularly punctate-striate. — Length 3 — 5 lines. 



Head with a few fine punctures and a more or less 

 distinct fovea at the vertex. Antennae extending to one 

 third the length of the elytra, the first 6 joints metallic 

 green , the rest opaque , black. Thorax more than twice 

 as broad as long , metallic green , the sides thickened, more 

 or less deeply foveolate-punctate, the disk remotely and 

 finely punctured. Scutellum greenish. Elytra fulvous, con- 

 vex , widened below the middle , finely and irregularly 

 punctate-striate. 



Of this species which is easily separated from C. stictica 

 Stal by the fulvous elytra, which are also much more 

 finely punctured than in that species, one specimen only 

 is contained in this collection ; it is captured at Solok by 

 Mr. J. H. Schagen van Leeuwen. Others which are before 

 me from Sumatra agree in everything but the shape and 

 punctuation of the thorax which seem very variable. So- 

 metimes the sides of the latter are nearly straight and the
