PHYTOPHAGOUS COLEOPTERA FROM MENTA WEI 137 



sulcus deep and sinuate, distinctly punctured, rest of the surface 

 impunctate, the median lobe of the posterior margin produced 

 but rounded, elytra transversely depressed below the base, the 

 shoulders prominent, the surface finely but distinctly punctate- 

 striate, the interstices at the sides slightly costate, underside and 

 legs fulvous, abdomen piceous. 



Hab. Sipora. 



Differing from any other species of this genus in the coloration 

 of the antennae in connection with the dark fulvous upper sur- 

 face and the piceous abdomen; seven specimens are before me. 



16. Enneamera nigra, sp. n. — Black, shining, basal joints of 

 the antennae testaceous, thorax extremely finely and sparingly 

 punctured, the lateral margin narrowly whitish, elytra punctured 

 like the thorax. 



Length 1 1 / 2 line. 



Head impunctate, without any elevations, antennae extending 

 to the base of the elytra, black, the lower three joints testaceous 

 below, the terminal six broadly flattened and pubescent, black, 

 thorax rather more than twice as broad as long, the sides 

 straight, the posterior margin nearly semicircular, the lateral 

 margins very narrowly pale yellowish or whitish , elytra scar- 

 cely perceptibly punctured, when seen under a very strong lens, 

 underside and legs black, the posterior tibiae slightly curved, 

 deeply chanelled. 



Hab. Sipora. 



The entirely black colour above and below, separates this 

 species from any of its allies, the extreme lateral margin of the 

 thorax and sometimes that of the elytra at the base are more 

 or less pale, in some specimens this is however nearly oblite- 

 rated. 



GALERUCINAE. 



17. Aulacophora denticornis, sp. n. — Flavous or fulvous, the 

 basal joints of the antennae dilated in the male , elytra black , 

 finely and closely punctured.
