DESCRIPTIONS OF TWO NEW GENERA, 

 AND OF SOME UNCilARACTERIZED SPECIES OF GALERUCIIV^. 



BY JOSEPH S. EALY, F.L.S. 



Emathea VIOLAOEIPENNIS. 



Sub-rotundata, postice paullo ampliata, convexa, fulva, nitida, anten- 

 narum articulis intermediis, oculis scutelloque nigris ; elytris sat crehre 

 punctatis, metalUco-violaceis. Long., 3 Ihi. 



Hah. : Burmali ; a single specimen (my collection). 



Head short, scarcely broader than long ; antennae half the length of the body, 

 the 4th to the 8th joints black, the rest fulvous. Thorax three times as broad as 

 long ; sides nearly straight, converging from base to apex ; disc shining, transversely 

 convex. Elytra much broader than the thorax, convex, faifitly excavated below the 

 basilar space, strongly and rather closely punctured. 



DORYIDA. 



In my original definition of tlie above genus, the four posterior 

 tibiae were described as being each armed with a short spine or tooth ; 

 Dr. Chapuis, to whom I lent one of my type specimens, followed me 

 in this ; but in a recent examination of both of the specimen in my own 

 collection, and also of that sent to Dr. Chapuis,! have failed to detect 

 any trace of teeth ; it must, therefore, be concluded that the original 

 diagnosis was erroneous, and that the four hinder tibiae are unarmed. 

 In the two species described below, all the tibiae are equally devoid 

 of spines. 



DORTIDA KIGEIPENNIS. 



Oblongo-ovata, convexa, fulvo-rufa, nitida, antennis, basi ex(:cptis,femo- 

 rum apice, tibiis, f arsis elytrisque nigris, his distincte subcrebre punctatis ; 

 thorace transversim convexo, xttrinque ad latus transversim sulcato, teriuiter 

 pimctato, punciis hie illic irregulariter congregatis ; disco utrinque piceo- 

 maculato. Long., 4 lin. 



Hah. : Siam, Mountains of Laos (Moiihot). 



Head not longer tlian broad ; antennse two-thirds the length of the body) 

 slightly attenuated at base and apex, the 2nd and 3rd joints very short, equal. 

 Thorax nearly three times as broad as long at the base ; sides rounded and con- 

 verging from the base towards the apex, the apical angle thickened and produced 

 into a broad transverse tubercle ; disc transversely sulcate on either side near the 

 lateral margin, finely but distinctly punctured, the punctures irregularly crowded over 

 the surface. Elytra broadly oblong, convex, irregularly punctured, the punctures 

 stronger than those on the thorax. 



DORTIDA TARSALIS. 

 Oblonga, convexa, piceo-fulva, nitida, antennis Jlavis ; pectore, abdomine 

 pedibus, femoribus anticis subtiis iarsisque exceptis, scutelloque nigris ; thorace 

 utrinque transversi7Ji sulcato; eli/tris mimite punctatis,apice extremo nigra. 



Long., 3 Un. 

 Hah. : Siam ?
