for Slough, little dreaming that in that phial 

 No 13, \\"as the most wonderful capture made for 

 man\- \-ears. On reaching home, I killed my twehe 

 captures, then <W3'/;(c7r, and was proceeding to brush and 

 clean it — its battledore wings were in a perfect tangle 

 requiring care to undo — when I was much troubled 

 h\ a minute piece of fluff or dust, w hich I could not 

 remove, so placed the Mynmr under the microscope, 

 when I was astonished beyond description, for I 

 looked for an ordinary Myiiiar piilcJicniis with its 

 abnormalh' short under-wings, instead of which, the 

 fluff I had tried to remove was an cloiv^atcd posterior 

 wing, with cilia of six hairs, and I realized that I 

 had captured a brand new species of Myiiiar \ As 

 soon as I had mounted it in balsam I telegraphed to 

 Mr. C. O. W'aterhousc : — '" Cai)tured new species of 

 Mvnntr. with battledore shaped under-wings."' This 

 brought us together, and we gloated over the 



distinguished visitor. I suggested that we should 

 christen it Myiinir rci^alls. in honour of His Most 

 Gracious Majesty, King George V . 



On Thursda}-. June 8th, Mr. C. O. Waterhouse 

 and I had a day at Burnham, and after five hours 

 sweeping in a bnjiiing sun, I was fortunate 

 in obtaining another male, so confirming the 

 genuineness of the species, which not onh- differs 

 from piilchelliis in its posterior \\ings, but the cilia 

 around the anterior pair are composed of some sixt\- 

 long hairs against thirty-five in pukhelliis. In other 

 respects, the colour and markings are similar. 

 .\nother long day in search of the unknown female 

 was not by any means a successful one: in fact, this 

 Myiiiar is but the one twenty-fifth of an inch in 

 length, and searching for such a creature on a wide 

 expanse of wood and common requires a large amount 

 of patient labour. 



SOL.VR l)I.STl'RI5ANCES DURING MAY, iqii. 

 By FK.WK C. DENNETT. 



0\ ten days durins May, namely the 10th to ISth, inclusive, and 

 the 24th, only facalic disturbances were visible on the disc, dark 

 spots being seen on the remaining twenty-one. The longitude 

 of the central meridian at noon on May 1st, was 152 46'. 



Nos. 17, 17(7 and 176, continued upon the disc until May 

 3rd, 5th and 2nd respectively-, and so appear again upon the 

 accompanying chart. 



No. 19. — A pore amid a faculic disturbance within the 

 eastern limb on the 2nd. and remaining until the 5th. the taenia 

 being still visible as it neared the western limb on the 14th. 



No. 20. — Broke out as a pair of pores 22,000 miles apart, on 

 the 4th. Next day the following one had increased to a 

 spotlet, and on the 6th it had developed to an elongated ellipse, 

 with a major a.\is 48.000 miles in length. It attained its 

 maximum length of 74,000 miles on the 7th. The dwindling 

 group reached the western limb on the 9th. Some of the 

 members on the 6th appeared as slits in the photosphere. 



No. 21. — On May 4th. a pore very similar to No. 19, 

 appeared in a faculic disturbance a little north-east of that 

 disturbance. Next day two pores were seen with others 

 ranged behind them like the border of an ellipse, with a length 

 of 48.000 miles. Much change took place in the appearance 

 of the group, which was last seen as six pores outlining an 

 oval area 26,000 miles in greatest diameter, on the 9th. 



No. 22. — A pair of pores 19.000 miles apart, with tiny dots 

 between them, only seen upon the yth. 



No. 23. — A spot seen on the 19th close within the eastern 

 limb. On the 21st it appeared to have a bridge across the 

 umbra, and also to be situated near the head of a considerable 

 faculic disturbance. Only two close umbrae were visible 

 amid taeniae on the 22nd, but when last seen on the 23rd, 

 there were three pores forming a triangle, the longest side 

 being 33,000 miles. The area still showed faculic disturbance 

 as it approached the western limb on May 31st. 



No. 24. — Bright faculic ridges were visible on the morning 

 of the 25th near the eastern limb, a little north, containing a 

 tiny pore. Other pores showed later and a spot over 7,500 

 miles in diameter developed during the afternoon. The latter 

 expanded until 14,000 miles across. The umbra was pene- 

 trated by a bright projection from the south, from the 28th until 

 the 30th. The pernunbra brightened at its inner border from 

 May 30th until last seen on June 5th. It was followed from 

 the 24th until the 31st, by a group of pores extending back 

 63,000 miles, and some were seen on the 1st and 3rd, close up 

 to the large spot. During its visibility it had a forward motion 

 on the Sun's surface amounting to fully 5° or 37,000 miles. 



Bright faculic disturbances were visible within the eastern 

 limb on the 16th, in the positions shown dotted on the chart, 

 about longitudes 240° and 255°. 



Our chart is constructed from the combined measures, 

 drawings, and descriptions of Messrs. J. McHarg, A. A. Buss, 

 E. E. Peacock, and F. C. Dennett, working respectively at 

 Lisburn, Chorlton-cum- Hardy, Bath and Hackney.
