176 Mr. F. M'Coy on the Irish species 0/ Cephaloptera. 



the outer margin, where its upper boundary is the second dis- 

 coidal nervule. Below, all the wings pale chocolate, with lavender 

 reflections, traversed by seven transverse lines; the first com- 

 mencing on the costa of the anterior wings near the base, con- 

 tinued along the precostal and first median nervule of the poste- 

 rior wings, the second continued across both wings to the ori- 

 gin of the second median nervule of the posterior wings, the third 

 short, just crossing the cell a little beyond the middle, the fourth 

 beyond the cell, continued nearly to the anal angle, the fifth more 

 oblique, only reaching the first median nervule of the posterior 

 wings, the sixth arising near the apex, meeting the fourth at its 

 termination, the seventh submarginal, common. Posterior wings 

 slightly produced into a short, round tail or palette at the anal 

 angle, having besides the markings already described two ocelli 

 composed of an oval black ring with a white pupil, the larger one 

 near the costa between the first and second subcostal nervule, 

 the second between the first and second submedian nervule at 

 the point of junction of the fourth and sixth strigse, the anal pa- 

 lette with two black dots edged with white. CiSa all white. 



Head, thorax, and abdomen brown. 



Female paler, with the band of the anterior wings much nar- 

 rower, not occupying any part of the cell, fulvous, marked near 

 the outer margin with a brown waved striga. 



In the cabinet of the British Museum, &c. 



Much resembling in form Amathusia Phidippus, but known at 

 once by the blue band above and different markings of the under 

 surface. ^ The blue band of the anterior wings gives it a consi- 

 derable resemblance to Zeuxidia Luxeri of Hiibner, but it wants 

 the blue on the posterior wings, and is totally different below. 



XXIII. — Note on the Irish species 0/ Cephaloptera (Pterocephala) . 

 By Frederick M^Coy, M.G.S. & N.H.S.D. &c. 



[With a Plate.] 



On looking over some memoranda lately, I found the following 

 notes and drawing, PI. XL, made some years ago, of the speci- 

 men of Cephalopteray originally noticed by Mr. Thompson of Bel- 

 fast, in the Museum of the Royal Dublin Society, and which may 

 be interesting to naturalists, as the specimen is still, so far as I 

 know, not only unique as Irish, but even the genus to which it 

 belongs has not been observed before or since in the British seas ; 

 and further, the specimen seems to be erroneously referred to in 

 most works on British zoology. 



I wish here to acknowledge the liberality with which Dr.
