and much more curved, especially in the female ; the legs longer 

 and distinctly stouter ; with the \ov\ex half of all the tihi?e black, 

 the upper part rufous. 



This insect is rather local and not frequently found ; I met with 

 it once rather plentifully in a red clover field ncai* Bu'ch Wood, 

 the beginning of June.

Mr. S. Stevens has found this species common in three localities 

 near Arundel annually, in the month of August ; also near Ryde, 

 Isle of Wight. I met with many specimens on a sand-bank on 

 Windmill Hill, Gravesend, in July : it appears to prefer sandy 

 situations.

XLIX. — Further Notice respecting Cyauocitta superciliosa, a sup- 

 posed new species of Blue Jay. By H. E. Strickland, M.A. 



In the last Nmnber of the "^ Annals,* p. 260, I proposed to sepa- 

 rate the Blue Jays of America from Cyanocorax, under the ge- 

 neric name of Cyanocitta, and I also pointed out a species of the 

 latter group which had been hitherto confounded with the C. ul- 

 tramarina of Mexico. When my paper went to press it happened 

 that I had not then received the ]\larch Number of ]\Ir. G. U. 

 Gray's excellent work the ' Genera of Birds,' which contains a 

 monographic summary of the subfamily Ganidince. He there 

 follows preceding authors in retaining the Blue Jays and the Blue 

 Crows under one genus, Cyanocorax, of which he enumerates in 

 the whole twenty-one species. There can however be no doubt 

 that these two groups are deserWng of generic separation, as they 

 not only differ in many points of structure and of colour, but also 

 in their geographical distribution, Cyanocorax proper inhabiting 

 the warm latitudes of South America, while Cyanocitta ranges 

 from ^Mexico to the colder parts of the North American con- 

 tinent. The latter genus may be thus defined : — 



Beak moderate, breadth at the base exceeding the height ; up- 

 per mandible depressed at the base, slightly compressed towards 

 the point ; culmen straight for 4ths of its length, then gradually 

 cur\ing down ; commissure almost straight till near the a])ex, then 

 curving downwards ; emargination nearly obsolete, gouys cm'ved 

 upwards, height of each mandible nearly equal. Nostrils covered 

 by recumbent bristly feathers. Frontal feathers not forming a 

 rigid erect crest as in many species of Cyanocorax. Total length 

 from 10 to 12 inches. Plumage more or less blue, especially on 

 the wings and tail, which are frequently baiTed transversely with 

 black. Structure of the feet, wings and tail as in Cyanocorax.
