PHYTOPHAGOUS COLEOPTERA FRO.M NEW GUINEA 507 



under side, the base of all the tibiae to a rather large extent 

 and the tarsi, pale testaceous, metatarsus of the posterior legs 

 very elongate. 



Ighibirei, Bujakori. 



The black coloration, very long antennae and the colour of 

 the legs and tarsi will help to distinguish this little species from 

 its numerous allies; in some specimens, the anterior portion of 

 the thorax is almost devoid of punctures but the punctuation of 

 that part seems to vary a good deal. 



46. 3£onolepta. Ixierog-lyphica, sp. n. 



Testaceous, thorax finely punctured, transversely depressed^ 

 with an M -shaped fuscous mark, elytra extremely minutely punc- 

 tured with three short stripes at the base and a transverse 

 row of small spots at the middle, piceous or dark fulvous. 



Length 4 millim. 



Head without punctures, the frontal elevations rather broad 

 and distinct, eyes large, oblong, antennae extending beyond the 

 middle of the elytra, pale, the terminal joints more or less 

 blackish, second joint very small, third one twice as long or 

 longer; thorax one half broader than long, subquadrate, the 

 sides feebly rounded, very narrowly margined, the disc obsole- 

 tely transversely sulcate at the middle, finely and closely punc- 

 tured and somewhat rugose, testaceous, a narrow stripe at the 

 lateral margins and an M -shaped mark at the middle of the disc, 

 brownish, scutellum small, elytra wider at the base than the 

 thorax, punctured like the latter, the punctuation finer towards 

 the apex, convex, not depressed below the base, each elytron 

 with three short longitudinal, dark brown stripes at the base, 

 these stripes are very thin and do not extend to the middle, 

 the outer one being the longest, they are followed immediately 

 below by a transverse row of small spots, (3 or 4) ; the elytral 

 epipleurae are absent below the middle ; under side and legs 

 testaceous, the metatarsus very elongate.
