There can, I think, be no doubt, after comparison with the 

 nearly allied Ethiopian forms, that fasciatella and aureola 

 are sexes of one species. It appears to belong to the desert 

 fauna, and is in the British ^luseum from Mogador, 

 Harkeko, and Karachi. By almost all authors a mistake 

 has been made in confusing it with a common Ethiopian 

 species, in which the mesonotum is highly polished and 

 almost without punctures and the wings strongly infuscated 

 along the costal margin. I consider that the descriptions 

 of Klug and Lepeletier both apply to the Xorth African 

 form, and cannot find that the Ethiopian species, which is 

 distinct h'ojnfelina, Sauss., has received a name. Saussure's 

 description applies to the Ethiopian species, as also docs 



TuUgreu's.

The male of this little-known desert species is still un- 

 known. It may possibly prove to be antennata, Klug, 

 which occurs Avith hyalina ? from ]\Iogador to Karachi. 

 Saussure looked on antennata merely as a variety of 

 fasciatella, and he may be right, both forms having the 

 recurrent nervures nearer together than is usual. It seems 

 to me, however, that the claspers oi fasciatella are distinctly 

 broader than in antennata, though the genitalia are other- 

 wise very similar. In the Escalera collection from Mogador, 

 hyalina $ was associated with S. {Trielis) villosa J; but 

 the dill'crences between hyalina and villosa are very con- 

 siderable, though villosa is so variable that it is quite 

 possible that hyalina may be a desert form of that species. 

 I3ut specimens of villosa from Biskra in the Saunders 

 collection differ much from the typical form in another 

 direction, the female having the abdomen rod ; the clypeus 

 shining, sparsely i)uncturcd, with short longitudinal stria; 

 at the apex ; the third cubital cell well defined, the radial 

 cell shorter aud narrower. In Spanish specimens of the
