DESCEIPTIONS OF SOME NEW SPECIES OF 

 PHYTOPHAGOUS COLEOPTERA. 



By Martin Jacoby, F.E.S. 



HALTICINiE. 



SiMJETHEA NIGEOPLAGIATA, n. Sp. 



Black ; the head and thorax flavous, the former with the base and the 

 latter with a central spot black ; elytra flavous, foveolate punctate-striate, a 

 transverse band at the base and a large ovate spot near the apex of each 

 elytron, black. Length, 4^ lines. 



Head impunctate, flavous, the base black, apex of mandibles black; 

 antennae extending to nearly half the length of the elytra, black, shining, the 

 third and fourth joints equal, elongate, the terminal joints shorter; thorax 

 subquadrate, shghtly broader than long, the sides straight at the base, 

 slightly rounded in front, the disc flavous, remotely foveolate-punctate, 

 the middle with an elongate narrow black spot ; scuteUum piceous ; elytra 

 with nine rows of deep foveolate punctures, remotely placed, the base with a 

 narrow black transverse band, not extending to the lateral margins, the 

 space below the middle occupied by a large ovate black spot not touching 

 either margin ; breast, abdomen, and legs, black. 



Hah. Java (Fruhstorfer) . 



S. nigroplagiata, of which I received a single specimen, forms 

 the third species of the genus Simcsthca {Atimeta, Chap.) ; it 

 agrees with the others in the deep punctuation of the elytra and 

 in general shape, but differs entirely in its system of coloration. 



PSEUDODERA BALYI, n. Sp. 



Eufous ; the antennte, tibis, and tarsi black ; the thorax impunctate, the 

 basal sulcation obsolete ; elytra finely puncture-striate, piceous, margined 

 with rufous, each with a large ovate yellow spot near the apex. Length, 

 3 lines. 



Head impimctate, the fi'ontal elevations strongly raised, oblong, bounded 

 by a deep transverse groove behind ; antennae, extending beyond the middle 

 of the elytra, black, the fourth joint slightly longer than the third ; thorax 

 but little broader than long, the sides very slightly rounded, the angles 

 obtuse, the surface impunctate, rufous, the basal sulcation obsolete, more 

 deeply marked at the middle and bounded laterally by a longitudinal groove ; 

 elytra finely punctate-striate, piceous, or nearly black, the sutural and lateral 

 margins narrowly rufous, as well as the extreme apex, the space in front of 

 the latter occupied by a large yellow ovate patch ; under side and femora 

 rufous, tibise and tarsi black. 



Hab. Chang-Yang, China (Pratt). 



This species was formerly looked upon by me as a dark 

 variety of P. xanthospila, Baly, but a closer examination has 

 proved to me that it must be considered a distinct species ; the 

 differences are the following : — The thorax in the present insect 

 has the sides nearly straight ; in P. xanthospila they are strongly 

 widened before the middle, and the basal sulcation is much 

 deeper and more marked ; the elytra also are much more 

 strongly punctured and are rufous, with the exception of the 

 flavous posterior spot, which is smaller than in P. halyi; the
