NEW PHYTOPHAGOUS COLEOPTERA 205 



and having the anterior angle produced into a short tooth. 

 The punctuation of the elytra (which are slightly depressed 

 below the base) becomes indistinct below the middle. The la- 

 teral striae are distinctly shorter than those at the disk. Two 

 specimens were obtained which agree entirely except in size. 



23, Rlxypa,i*id.a eastanea,, n. sp. 



Oblong, dark or light fulvous. Episteme concave, coarsely 

 punctured. Thorax very remotely but strongly punctate. Elytra 

 depressed below the base , deeply punctate-striate , the interstices 

 semiconvex. 



Length 3 lines. 



Head impunctate or extremely minutely punctured; episteme 

 distinctly separated from the face, as long as broad, its ante- 

 rior margin very deeply concave-emarginate , its surface trans- 

 versely concave , with three rows of very deep punctures , placed 

 transversely; eyes strongly emarginate at their inner margin. 

 Antennae slender, of half the length of the body, entirely ful- 

 vous. Thorax twice as broad as long, the sides regularly roun- 

 ded , scarcely narrowed anteriorly , all the angles tuberculate , 

 surface subopaque, with but few remotely placed but strongly 

 impressed punctures; scutellum not longer than broad. Elytra 

 moderately convex, obsoletely depressed below the base, regu- 

 larly and deeply punctate-striate, the punctuation becoming finer 

 towards the apex. Femora unarmed. 



New Guinea, Fly River (L. M. D'Albertis , 1876). 



There are two specimens of this species before me, one of 

 a dark fulvous, nearly piceous, the other of a light fulvous co- 

 lour; the nearest allied species seems to be R. geniciUata Baly 

 and R. fuluipes Baly, from both of which it is separated by the 

 impunctate head, the punctuation of the episteme and that of 

 the thorax in connection with the shape of the former. R. ful- 

 vipes is also described as having no depression below the base 

 of the elytra.
