of the sac. The margin of the plate next the fundus is thickened, and inclines 

 towards the fundus ; the angle between this margin and the attached margin is 

 about 135°. It ends in a sharp point; the rest of the plate forms a sort of 

 bracket or support to this special spinous margin. The accompanying diagrams 

 made fi-om camera sketches may be of interest : they i-epresent plates ( x about 

 200) of the bursa of rusticella ? ."

DESCEIPTION OF A NEW SPECIES OF GALERUCELLA. 

 BY THE REV. W. \V. FOWLER, D.8c., M.A., F.L.S. 



Galeeucella fergussoni, sfi. nov. 



G. SAGiTTABi^ affi,nis, sed multo minor ct hrcvior, sat nitida, tola nigra, vcl 

 marginihus ehjti'orum jyeranguste dilutiorihus : antennis articulo secu7ido ■pro 

 ratione tertio paullo longiori : pironoto angulis lateralihus magis distinctis ; elytris 

 interspatiis punctoruvi evidentius alutaccis. 



A small dark species of about the size of G. lineola, closely allied 

 to G. sagittarice, but at ouce distinguished by its small size aud dark 

 colour : entirely black, or with the margins of the elytra very narrowly 

 dusky yellowish ; there are also in some instances lighter markings on 

 the prouotum : the ant«nna3 have the second joint slightly longer in 

 proportion than the third : the lateral angles of the pronotum are 

 more pronoimced and in this respect the insect rather resembles G. 

 nijmi^hxx, which I believe with Dr. Sharp to he a distinct species from 

 G. sagittarice ; the sculpture of the elytra is variable as in the last 

 named species, but the interstices appear to be somewhat more plainly 

 alutaceous ; the grey pubescence is more distinct and appears to be 

 thicker, but this is in part due to the darkness of the el}i:ra.
