LIMNOBIA. 303 



with the third externo-medial by a veinlet, whose angle emits a vein, 

 which is the common petiole of the first and second externo-medial, 

 and is rather less than half the length of the latter ; first externo-me- 

 dial forked before half its length ; subanal connected with the third 

 externo-medial by a veinlet, which is some distance beyond the veinlet 

 between the third externo-medial and the cubital.

" Cinereous. Antennae and palpi blackish. Mesonotum with three 

 obsolete darker stripes. Wings light brownish-hyaline, with brown 

 spots on the transverse veins and at the bifurcation ; veins nearly as in 

 L.punctata; the transverse veins which close the two brachial areo- 

 lets nearly continuous, their brown shading continued along the bifur- 

 cation of the radial and cubital veins, and the embranchment of the 

 former and the end of the mediastinal vein (here connected as usual 

 with the costal and subcostal both) forming a sinuous band half across 

 the wing ; a large brown spot occupies the middle of the prsebrachial 

 areolet, extending over part of the pobrachial and the base of the inner 

 radial, and to the costa ; another near the base of the wing, occupying 

 the base of the two brachial areolets, and also extending to the costa ; 

 at the tip of the anterior branch of the radial vein a brown dot, a 

 brown spot across the middle of the anterior radial areolet, a brown 

 cloud surrounds the closing veins of the discal areolet, and another 

 the bifurcation of the first externo-median vein, and there are usually 

 some faint brownish dots at the tip, or along the course of some of the 

 externo-medial, and the cubital vein. The radial vein parts into two 

 branches almost immediately after the emission of the cubital, and the 

 anterior is there connected with the subcostal, and again in the middle 

 within the brown spot, but the former connection is obsolete ; the
