the lu'ad behind the eyes is not so pult'od out, and the front margin of the fi'ons is 

 more eoncavc, leaving the inter-antennal prominence more conspicuous from above. 

 It may be known at once from the female of the other two species by its having 

 only three pairs of outer dorso-central bristles, by its wider face, and by the colour 

 of its antennte, which are even paler than in the male. 



T bave onl}'^ seen four British specimens of this species : two 

 males, one taken bv Mr. Percy Grimshaw at Spring Wood, Bradford, 

 Yorkshire, the other by Dr. J. H. Wood, at Stoke Wood, near Tar- 

 rington, Herefordshire ; and two females, one taken in June by Mr. 

 Verrall at Rannoch in Scotland, the other in July by Col. Terbury, 

 also at Rannoch ; Dr. Meade has recorded TephrocJilamys magnicornis 

 from Bradford in Yorkshire, and "from Pitlochry in Perthshire {vide 

 Ent. Mo. Mag., 1S99, p. 101). Of continental specimens I have seen 

 two females, both apparently from Prof. Mik, at least they bear a 

 label with his name, one in Kowarz's collection labelled. Hammern, 

 13.9.72, the other in Bigot's collection, labelled Austr. sup., — .9.72. 



Holiday's ociilata of 1833 was the previous species, while Thelida 

 occul'ta, Schin., =r //. atricornis, Mg. The female has been known 

 since 1S59 as Tcpliroclilamys magnicornis, Lw.
