DESCRIPTIONS OF SOME NEW SPECIES OE PHYTOPHAGOUS 

 COLEOPTERA. 



BY MAETIN JACOBY, F.E.S. 



Sagra papuana, n. sp. 



Metallic cupreous or blue ; the last four joints of the antennae black ; thorax 

 subquadrate, scarcely visibly punctured ; elytra narrowed posteriorly, the basal 

 portion raised, obsoletely geminate punctate-striate, the interstices transversely 

 ■wrinkled at the sides, cupreous, a spot near the sides greenish. 



Mas : posterior femora scarcely extending beyond the apex of the elytra, strongly 

 widened at the middle, armed with a larger and a smaller tooth placed below near 

 the apex ; posterior tibise stout, curved, thickly tomentose on their inner surface, 

 with a single stout triangular tooth below the middle, intermediate femora curved 

 at the base ; first abdominal segment clothed with fulvous pubescence. 



Fern. : posterior femora with a short acute ridge near the apex, their tibise 

 strongly curved, unarmed and without pubescence ; the first abdominal segment 

 smooth, not pubescent. Length, 6 — 8 lines. 



Sab. : New Guinea, Port Moresby (collection, Jacoby). 



The male of this Sagra may be known from most of its allies by 

 the thickly tomentose inner side of the posterior tibise and their single 

 stout tooth, also by the comparatively short posterior femora ; the 

 thorax is nearly square, the anterior angles are not prominent but 

 rather obtuse, bounded by a short but deep groove within, the surface 

 is either almost entirely impunctate or impressed with very few 

 minute punctures ; at the middle of the base a short longitudinal 

 groove is placed ; the elytra have prominent shoulders, bounded by a 

 short longitudinal groove, their punctuation consists of double and 

 rather irregular rows, of which the pair within the humerus is more 

 distinct and oblique in direction, the interstices near the sides and 

 apes, and to a less extent on the disc, are transversely wrinkled ; the 

 colour varies from metallic cupreous to green or entirely blue ; in the 

 cupreous coloured specimens there is a small green patch of more or 

 less intensity, placed on the sides of each elytron. 



Megaloptjs Buckleyi, n. sp. 



Elongate, strongly narrowed posteriorly, black, the sides of the thorax, parts of 

 the breast and abdomen, fulvous ; elytra closely punctured and rugose, a narrow 

 angulate band before, another behind the middle and the apex (with the exception 

 of a black spot), fulvous. 



Mas : the posterior femora very large and robust, black above, fulvous below, 

 armed with a small and a very large tooth, their tibise very strongly curved. 



Length, 7 lines. 

 Fern. : the elytral bands yellowish-white ; the legs feeble and entirely black. 



Length, 5 lines. 

 Sab. : Ecuador.
