middle of the elytra, black, ihe second and third joint equal or 

 nearly so, the others longer, slightly and gradually thickened, the 

 lowerthree joints more or less testaceous at the base; thorax sub- 

 qaadrate, the sides nearly straight, the anterior angles oblique, the 

 surface entirely impunctate, shining, scutellum black, elytra nearly 

 impunclale, only a few minute punctures being visible near the 

 base, when seen utider a strong lens, the suture narrowly piceous, 

 wings présent, the first joint of th i posterior tarsi as long as. the 

 following two joints together. 



Separàted from other Indian species of the genus by the black 

 underside and the colour of the legs, from A. nigrilahris Duviv. 

 by the colour of the antennse, the much less broad thorax and 

 the smooth elytra as well as by the colour of the legs and under 

 side. 



PSEUDAPHTHONA gen. n. 



Body subquadrately oblong, antennse thickened at the terminal 

 joints, palpi robust, thorax subquadrate, without sulcus, the 

 anterior angles oblique, elytra irregularly punctured, tibiae dilated 

 anteriorly, sulcate, the anterior and intermediate ones unarmed, 

 Ihe posterior with aspine, posterior femora thickened, prosternum 

 Iwice as long as broad, longitudinally sulcate, the anterior coxal 

 cavities open; claws appemliculate. Allied to Aphthona but sepa- 

 ràted by the unarmed anterior tibise which are also distinctly 

 dilated and by the elongate and sulcate prosternum. I cannot refer 

 this species to Weise's genus Luperomorpha in which the second 

 and third joint of the antennse is extremely small and the elytra 

 finely pubescent posteriorly, nor does Weise mention any dilated 

 apical joints of the antennae or says anylhing about the anterior 

 tibise whether Ihey are armed or not. 



PSEUDAPHTHONA HUMERALIS sp.n. 



Below black, above metallic dark blue, thorax sparingly punc- 

 tured, elytra rather strongly and closely punctured, with atransverse 

 basai dépression and a short humerai ridge extending nearly to the 

 middle of the sides. 



Length 3 mill. 



Head inserted as far as the eyes, impunctate, frontal élévations 

 distinct, trigonate, antennte extending to about half the length of 

 the elytra, black, the second joint one half shorter Ihan the first, 

 the third and following joints oiily slightly longer but distinctly 

 thickened; thorax one half broader Ihan long, the sides very feebly
