253 Mr. J. S. Ealy on new Genera and Species of Gallerucidse. 



Genus MoMiEA. 



Corpus elongatum aut subelongatum, convexum. Caput crassum, 

 valde exsertum ; fronte lata, declivi ; facie perpendiculari ; mandi- 

 hulis magnis ; antennis corporis longitudini sequalibus aut paullo 

 brevioribus, iiliformibus, ad apicem attenuatis, articulo primo cur- 

 vato, a basi ad apicem incrassato, secundo primi dimidise parti sequali 

 aut paullo breviore, tertio elongato, articulo quarto longiore, cseteris 

 singulatim quarto sequalibus ; palpis maxillaribus crassis, apice acu- 

 minatis ; oculis vix prominulis, iutegris. Thorax transversus, lateribus 

 anguste marginatis, obtuse angulatis, augulis omnibus tuberculo seti- 

 gero instructis ; disco transversim concavo, medio lougitudinaliter ex- 

 cavato, utrinque transversim sulcato. Elytra metallica, thorace 

 latiora, fere parallela, convexa, infra basin transversim depressa, con- 

 fuse punctata, glabra aut postice pube tenuissima sparse vestita. 

 Pedes modice robusti, sat elongati ; coxis anticis erectis, fere conti- 

 guis ; femorihus posticis non incrassatis ; tihiis omnibus apice muticis ; 

 tarsorum posticorum articulo basali duobus sequentibus longiore ; 

 unguiculis bifidis. Prosternum lineariforme. 



Type, Momcea viridipennis. 



The longer third joint of the antennse, together with the 

 different manner in vi^hich the thorax is excavated, will separate 

 this genus from Nicea and Emncea, two nearly allied forms. 

 There is a slight error in the characters given by me of the latter 

 genus (Annals, January 1865, p. 37) ; it ought to read — "Pro- 

 sternum angustissiraum aut obsoletum ; tibiis coxis anticis con- 

 tiguis/' In both Nicea and Eumcea all the tibise have their apices 

 unarmed. 



Momaa viridipennis. 

 M. elongata, convexa, fusco-fulva, uitida ; capite (cpistomate excepto) 



nigro-piceo ; pedibus antennisque uigris ; elytris viridi-ajneis, 



crebre punctatis, sparse fusco-sericeis. 

 Long. 5| lin. 



Hah. Mysol. 



Head large; jaws robust, prominent; forehead deflexed, im- 

 pressed in the middle with a deep longitudinal fovea ; surface shi- 

 ning, irregularly but not closely punctured : encai'pse contiguous, 

 triangular ; lower portion of face, together with the base of the 

 jaws, obscure fusco-fulvous. Thorax more than twice as broad 

 as long; sides obtusely angled, diverging and slightly sinuate 

 from their base to just beyond the middle, then converging 

 to their apex ; upper surface transversely concave, impressed on 

 the hinder half of the middle disk with a large longitudinal 

 fovea ; on either side is a deep but ill-defined transverse depres- 

 sion which extends from the outer border nearly to the medial 

 line. Elytra subelongate, nearly parallel, convex ; their surface 

 convex, excavated and sinuous below the basilar space, about the
