distinguishes Diopsis. The fore femora are incrassated (more so than 

 in any Diopsis I know of). — 



I have no specimen of the typical N. Amer. Sphpracephala brevi- 

 cornis for comparison, but as Prof. Westwood mentions the large 

 alulae of his Sph. hearseyana (Cabinet of Orient. Entom. Plate XVIII 

 1848) as a ground for referring it to Say's genus, and as Prof. Loew 

 (Zeitschr. f. d. Ges. Naturw. Vol. 42, 101, 1873) has the distinct Pro- 

 longation of the sixth vein among the characters which he assigns to 

 Sphyracephala, 1 have but little doubt tbat I am right in referring the 

 above-named two species to the same genus. Moreover, S. Beccarii 

 must be exceedingly like S. hearseyana in its coloring, as Prof. 

 Westwood's description is applicable word for word to it, except that 

 the infuscated tips of the bind femora of S. Beccarii are not men- 

 tioned. 



Assuming therefore the generic identity of those three species, 

 there would be no necessity for the genus Mexecliopsis Rondani (Ann. 

 Mus. Civ. Gen. VII, 442, 1875) introduced for Diopsis Beccarii, but 

 very insufficiently characterized. S. cothurnata differs from the other 

 species in the absence of the usual vertical bristle, each side, between 

 the eye and the ocelli; but this is not a sufficient generic character. 



Dr. Loew described a new species from the region of the Amur 

 River, S. nigrimana Lw. I assume its identity with the species from 

 Wladivostok (in the same region), which Mr. Portchinski took for 

 Say's species (Horae Soc. Ent. Ross. VIII, 287, 1871). Dr. Loew also 

 described a S. succini from the prussian amber. 



The living species of Sphyracephala, at present kuown, may be 

 grouped as follows: 



Wings without spots 



Asiatic sp hearseyana Westw, 



African sp Beccarii Rond. 



Wings spotted 



The dark crossband in the middle of 

 the wing does not reach the Costa. 



Asiatic sp cothurnata Bigot. 



The dark crossband etc.reaches the costa. 



Front tarsi black. North- Asiatic sp. nigrimana Lw. 



Front tarsi yellowish. North-Ameri- 



can sp hrevicornis Say.
