96 Mr. J. S. Baly on six new species 



dinal rows on each elytron, — the first row abbreviated, the others ap- 

 proximating in pairs ; on the outer border is also a single row of finer 

 punctures ; interspaces shining, slightly swollen, impressed with a few 

 fine scattered punctures ; the striae here and there deeply sulcate. 

 Body beneath subremotely punctured. 

 Hab. Northern China. 



4. Chrysomela separata. 



C. oblonga, convexa, nitido-cuprea ; thorace transverso, lateribus rotun- 

 datis, subincrassatis, profunde rugoso-punctatis, disco spai-se hie illic 

 fortiter punctato; elytris profunde punctatis, punctis in striis inter- 

 ruptis dispositis. — Long. 4 lin. 



Oblong, convex, shining cupreous. Head vaguely punctured; an- 

 tennas scarcely half the length of the body, robust, nigro-aeneous. 

 Thorax twice broader than long; sides slightly ampliate-rotundate, 

 narrowed in front : disk sparingly covered with large, deep, irregularly 

 crowded punotures; sides incrassate, deeply and coarsely rugose-punctate, 

 their inner edge bounded by a longitudinal depression. Scutellum 

 smooth, impunctate. Elytra subovate, convex, deeply porose-punctate ; 

 punctures large, somewhat irregularly arranged in interrupted longitu- 

 dinal rows (about ten in each elytron), which indistinctly approximate 

 in pairs; interspaces smooth, slightly swollen, impunctate. Body 

 beneath shining cupreous, finely but remotely punctured ; legs nigro- 

 seneous. 



Hab. Northern India. 



At once distinguished from the preceding species (to which it is 

 otherwise closely allied) by its narrower and less convex form, and 

 by the rugose lateral border of its thorax. 



5. Chrysomela Boivringii. 



C. oblonga, convexa, nigro-aenea, nitida ; thorace disco fortiter- et irregu- 

 lariter-, lateribus rugoso-punctato ; scutello elytrisque rufo-testaceis, 

 aeneo vix micantibus, his subcrebre subseriatim punctatis ; abdomine 

 ad apicem plus minusve rufo-testaceo. — Long. 4 lin. 



Oblong, convex, nigro-aeneous, nitidous ; scutellum and elytra rufo- 

 testaceous, with a faint metallic reflexion. Head punctured ; antennas 

 half the length of the body, slightly incrassate towards their apex. 

 Thorax nearly twice broader than long; sides slightly rounded, narrowed 

 towards their apex, sometimes notched at the base, anterior angles sub- 

 acute : disk irregularly punctured ; sides moderately incrassate, coarsely 

 rugose, boimded within by a longitudinal depression. Elytra four 

 times the length of the thorax, oblong-ovate, sides slightly oval, apex 

 regularly rounded ; above moderately convex, surface covered with 

 numerous irregular rows of deeply impressed but not very large punc-
