90 Mr. P. Cameron on IlymenojJtera 



C'lice. Wino'S clear hyaline, the nervures and stigma blaek ; 

 the second cubital cellule much narrowed in front, one fourth 

 of the length of the third in front ; the first recurrent nervure 

 received very shortly beyond the transverse cubital, the 

 second at the apex of the basal fourth ; metanotura without 

 keels, except two indistinct longitudinal ones leading down to 

 the furrow, which is distinct, smooth on upper, crenulated on 

 lower half; the narrowed part of petiole half the length of 

 thorax. Body smooth ; the pubescence densest and longest 

 on the sides. ? . 



Lengtii 7 nnn. 



Simla (Nurse). 



May be known from the other black Indian species by the 

 absence of keels and areaj on the metanotum, it being also 

 smaller than them. P. kaskmirensis, Nurse, has a " remark- 

 able tubercle " between the antenna?, and it agrees otherwise 

 with the present species closely, but it differs in having a 

 triangular depression at the base of the metanotum, which 

 also bears outwardly diverging striae, this not being the case 

 with the present species. 



Psen riifoannulatus, sp. n. 



Black, shining, densely covered with longish white pubes- 

 cence ; the second and third abdominal segments bright red ; 

 the apical four joints of the tarsi rufo-testaceous ; the wings 

 clear hyaline, the stigma and nervures black; abdominal 

 })etiole as long as the thorax ; the front with a distinct keel 

 down the middle. ? . 



Length i) mm. 



Simla; August (Nurse). 



A stout species. 



Metanotal area bare, shining, large, clearly defined, the 

 apex gradually roundly narrowed to a point shortly above 

 the middle of the metanotum ; in its centre are two parallel 

 keels ; at a distance from these is a keel ; separated from it 

 at the outer edge are three or four less distinct ones. The 

 rest of the metanotum is opaque, irregularly striated, the 

 striae more or less curved ; the pubescence is long and dense. 

 The first recurrent nervure is received near the apex of the 

 basal third of the cellule, the second very shortly beyond 

 the second transverse cubital. Hind tibias with about a 

 dozen white spines. The second abscissa of radius not quite 

 half the length of third ; the second cubital cellule wide iu 

 front.
