238 Mr. R. M'Lachlan's Descriptions of the 



hotly ochreous ; anterior wings pale yellow, the veins rather 

 hroadly but indistinctly margined with very pale yellowish-grey, a 

 faint appearance of a series of elongated spots in the apical cells ; 

 posterior wings sub-hyaline, tinged with yellow, especially towards 

 the tips. 



Upper margin of last abdominal segment cut off straight ; 

 appendices superiores rather square, deeply notched on the apical 

 margin, forming two points which project beyond the margin of 

 the last segment ; appendices inferiores ochreous, long, straight 

 and cylindrical, thickened at the tips, which are intensely shining 

 black ; upper pair of sheaths broad, triangular and curved out- 

 wards ; between the inferior appendages a tuft of long hair con- 

 ceals the lower sheaths. 



Long. corp. 8 lin. ; exp. alar. 19 lin. 



Of this species I only know of the two type-specimens in Mr. 

 Curtis's collection. 



In general appearance not very unlike the last species, but the 

 appendages are very different. A great confusion has arisen as to 

 this and the next species ; the inferior appendages are very 

 similar, being clubbed at the tip in both species, but this has the 

 apex of the anterior wings parabolic, whereas in the next they are 

 almost circular. Curtis's types are very pale coloured, and in 

 this respect scarcely agree with Pictet's and Kolenati's descrip- 

 tions, but, according to Dr. Hagen, the form of the appendages is 

 identical. In the British Museum, Stephens's series of stellalus 

 was ticketed by Dr. Hagen as ^' joanlherinus, Kol.," but as these 

 insects are identical with steU'otus, Curtis, and as at that time he 

 had not seen Pictet's types, sorne error may have occurred.

 Limnephihts stellatus, Curt. Phil. Mag. 1834, p. 125 — 32;

 Antennae, head, thorax and abdomen above dark fuscous, 

 almost black, beneath dark brownish red ; legs reddish, with black 

 spines ; anterior wings more rounded at the apex than in the last 

 species, dark brownish grey, very pilose, with elongate pale spots in 

 several of the cells, and a bilobed spot about the thyridium ; two 

 spots beyond the anastomosis, and a series of streaks in the 

 apical cells, also paler: of these markings, the bilobed spot and 

 the two spots beyond are conspicuous, the others usually in- 

 distinct and sometimes wanting ; posterior wings sub-hyaline, 

 slightly smoky, especially towards the apex. 



Upper margin of last segment cut off straight ; appendices 

 superiores small, concealed ; appendices inferiores straight, thin
