254 Mr. J. S. Baly on new Genera and Species of Gallerucidse. 



bus apice anguste ovatis, acuminatis. Thorax transversus, lateribus 

 medio ssepe angulatis ; disco subplano, medio longitudinaliter 

 sulcato, utrinque transversim impresso ; angulis omnibus tuberculo 

 setigero armatis. Elytra elongata aut subelongata, fere parallela, 

 postice vix ampliata, anguste explanato-marginata, convexa, dorso 

 subdeplanata, infra basin non aut vix transversim depressa, pube 

 sericea plus minusve dense vestita, confuse punctata, ssepe disco ex- 

 teriore longitudinaliter sulcata. Pedes graciles, elongati ; coxis anticis 

 contiguis aut fere contiguis ; femoribus posticis non incrassatis ; tibiis 

 omnibus apice muticis ; tarsorum anticorum articulo basali duobus 

 sequentibus longiore; unguiculis bifidis. Prosternum angustissimum, 

 saepe fere obsoletum. 



Type, Sastra placida. 



The smaller head, much shorter and transverse face^ together 

 with the much more pubescent upper surface of the body, will 

 sufficiently distinguish Sastra from Momcea. 



Sastra placida. 



S. elongata, modice convexa, sordide flava, nitida ; abdomine anten- 

 nisque fuscis, his basi pallidioribus ; elytris dense punctatis, pube 

 adpressa fusca vestitis, pallide fusco-violaceis. 



Long. 4 lin. 



Hab. Mysol. 



Head impressed with a longitudinal groove, which extends 

 from the anterior edge of the epistome to the vertex ; encarpse 

 contiguous, large, pentagonal. Thorax nearly twice as broad as 

 long ; sides nearly parallel, slightly rounded in front, narrowed 

 posteriorly ; middle of disk impressed with a longitudinal sulca- 

 tion, which extends from base to apex, but is interrupted in its 

 middle; on either side is a broad transverse depression which 

 occupies nearly a third of the whole surface ; scattered distantly 

 over the thorax, but rather more crowded on the anterior mar- 

 gin, are some large deep punctures. Elytra subparallel, lateral 

 border narrowly dilated, flattened along the suture, closely punc- 

 tured; densely clothed with adpressed fuscous pubescence; on 

 the outer disk are two shallow longitudinal sul cations, separated 

 from each other by an elevated ridge. 



Sastra limhata. 

 S. elongata, pallide flava, nitida ; oculis nigris ; elytris metallico- 



violaceis, singulatim palKde flavo limbatis. 

 Long. 3 1 lin. 



Hab. New Guinea. 



Face short, transverse; space between the insertions of the 

 antennae broad, impressed with a longitudinal groove, which runs 

 downwards across the epistome and upwards to the vertex ; ca- 

 rinse large, contiguous, subpyriform; antennae four-fifths the 

 length of the body, slender; apex of jaws piceous. Thorax
