Sm.^ do not exist in the type. Cameron's description is 

 applicable to typical ma dr a spa tana, except that the type has 

 the clypeus carinated. I have seen a specimen from Poona. 

 This species will probably prove to be the female of Myzine 

 dimidiata, Guer. 



Fiesta (Mesa) dimidiata, Guer. 



Myzine dhnicUata, Gu^r. Diet. pitt. hist. nat. v. p. 584. n, 17, c? . 

 Methaca orientalis, Sm. Cat. Ilym. B. M. iii. p. 66. a. 3 (1856_), J (nee 

 Smith, 1875). 



Smith's type is not marked in the B.M., but his description 

 agrees well with Guerin's species; and in describing Methoca 

 orientalis in 1875, he states that it is the first .«pecies of the 

 genus recorded from India. He has made a similar mistake 

 in describing Methoca mandihularis (1869, Trans. Ent. Soc. 

 London), which is also a Plesia. 



Plesia (Mesa) purpt/reipennis, sp. n. 



? . Clypeus deeply but sparsely punctured, with an indis- 

 tinct carina from the base, broadly subtruncate at tlie apex, 

 the apical margin smooth and shining. Mandibles with a 

 S))arse fringe of fulvous hairs on the outer margin ; scape 

 shining and sparsely ])unctured, smooth at the apex, with a 

 few long fulvous hairs beneath ; the tlagellum opaque, the 

 first joint shining and sparsely punctured. Front coarsely, 

 vertex sparsely and rather more tinely punctured, a large 

 space round the anterior ocellus smooth and shining. Pro- 

 notum and scutellum very coarsely punctured rugose ; meso- 

 notum sparsely punctured, with two sulci on each side, the 

 inner sulcse broad and converging towards the posterior 

 margin. Median segment very finely rugulose, with a broad 

 transversely striated sulcus from the base to the apex, the 

 sides of the sulcus raised and forming carinse, the posterior 

 truncation of the segment shining, sparsely and shallowly 

 marked with large punctures, the sides of the segment 

 obliquely striated. Propleur^ rugose striated posteriorly, 

 mesopleurai exceedingly coarsely punctured. Abdomen 

 shining, rather sparsely punctured, most strongly on the 

 basal segment, very sparsely on the second ; the epipygiuni 

 finely and closely longitudinally stiiated, rounded at tJie apex, 

 the hypopygium narrowly truncate at the apex. The second 

 cubital cell is very little shorter than the third on the radial 

 iiervure, the first recurrent nervure is received close to tlie 

 middle of the second cubital cell, the second at two-thirds 

 from the base of the third cubital cell.
