DESCRIPTIONS OF SOME NEW GENERA AND SPECIES 

 OF PHYTOPHAGOUS COLEOPTERA FROM NEW 

 GUINEA. 



By Maktin Jacoby, F.E.S. 



Among the specimens obtained by Mr. A. S. Meek in a com- 

 paratively unknown region of New Guinea just behind that 

 part claimed by Germany, and received by Mr. 0. Janson, some 

 very interesting new forms are contained, the more conspicuous 

 and remarkable of which I give the descriptions here. 



Msernia Meeki, sp. n. 



Metallic purplish or greenish, the antennfe and tarsi bluish-black, 

 last abdomiual segments flavous ; thorax impunctate, deeply foveo- 

 lately excavated at the sides, cupreous ; elytra deeply punctate-striate 

 and longitudinally costate anteriorly, this portion purplish, posterior 

 half finely punctured, smooth, flavous. Length, 20 mill. 



Head metallic green, with a deep central groove, a few punctures 

 ( are placed near the eyes, the rest impunctate ; in front of the clypeus 

 is a deep depression or fovea ; antennae bluish-black, extending to 

 about the middle of the elytra, third and the following two joints 

 of equal length, terminal joints more elongate and slender. Thorax 

 scarcely twice as broad as long, the sides straight, the anterior angles 

 pointed and produced, the disc with a deep longitudinal central groove, 

 cupreous, the sides deeply excavated and foveolate, some of the foveae 

 extending nearly to the middle of the disc, the latter itself impunctate; 

 scutellum rounded, metallic green, with a small fovea at the apex. 

 Elytra with the middle portion strongly but gradually raised, the 

 sides with a deeper transverse depression before the middle and 

 a smaller one at the latter place, strongly longitudinally costate 

 anteriorly, the strife between the costse more or less strongly and 

 closely punctured, the costate portion metallic green, the posterior 

 half of the elytra flavous, finely punctured, and flat ; below and the 

 legs metallic green, the last three abdominal segments flavous.
