so THE entomologist's kecokd, 



liotli for larv;e and imagines, I was not fortnnate enough to meet with 

 tlie variety. This f()rm woukl prol)ably be identical with the black 

 sjiecimens recorded two years ago from Warrington. Specimens which 

 1 collected in Edlington Wood, Doncaster, do not differ from the 

 southern type. Hadena oleraeea. — This species bred from Horsfortli 

 larvfe. is distinctly darker than specimens from the London district. 

 Hadena dentina. — Four specimens only were captured: — (l)very dark, 

 .almost l)lack ; Horsfortli. (2) Dark grey ; York. (3) Markings very 

 indistinct ; Grass Wood, Yorks. (4) Type ; York. Mr. Porritt toLl 

 me the dark form (1) is met with every year at Huddersfield 

 in some a1)undance. 1 lind from the York collectors, however, 

 that it is not taken in the East Eiding. Gkobietr.e. — Odontopera 

 hideutafa. — Very dark specimens of this moth are taken in the 

 Horsfortli district, together with the tyjie. Extreme forms are 

 jdmost as dark as Forres s]ieciinens. Boarmia repanduta. — Four 

 black specimens in my series represent the Horsfortli form as 

 bred. 1 found eight larvje, and from them I obtained eight black 

 imagines ; l)ut of 50 or sixty captured specimens, not one was so 

 ■dark. When I hrst l)red the insect, I thought I had got Mr. Porritt's 

 Idack form ; l^ut on comjjaring with his well known varieties, mine 

 were found to be much lighter, lilack specimens, said to be identical 

 Avith those bred by Mr. Porritt from Huddersheld larv;e, were bred by 

 Mr, Hall of Sheffield, from larva? found in his district. The dark 

 Horsforth form was well known to both these gentlemen, and they 

 state that it is abundant every year. B. rejmndata from Grass Wood 

 near Ski^ijton, Yorks, and from Y^ork, are much ligliter than Horsforth 

 captured specimens. Phigalia pedaria = jjilosaria, Hb. — Occasionally 

 a very ilark unicolorous olive-black variety is taken in the West 

 liiding ; it has l)eeii recorded from Harrogate and Barnsley. My speci- 

 men was taken in a very boggy wood at Otley, near Leeds. I worked 

 hard last season, Ijut did not meet Avitli another var. although the type 

 was common. Tepliro»ia hiundidaria. — The northern * form of this 

 insect is well known = var. delamerensis. It is taken all over 

 Yorkshire where the type occurs, and recent records show that it is 

 rapidly s^u'eading. My series was taken in Edlington Wood, neai' 

 Doncaster. Hyheruia leucophcearia. — The var. marrnorinaria is Avell 

 known to the Y^oi"k collectors ; it occurs in al )out the same proportion 

 to the type as in the southern woods. Hyhernia aurantiaria. — My 

 Yorkshire examples of this insect are much dee^Der coloured and have 

 a larger area of purple on the fore Avings, than have specimens from 

 Surrey. Typical Horsforth examples are similar to those from Askhani 

 ] >og and Sand) lurn Wood in the York district. I have two extremely 

 pale forms from Horsforth, Ijut they are (juite abnormal there. Con- 

 sidering the yd\m\ spread of the deeper coloured pigment in the allied 

 species H. laargiuaria, and the strong tendency in the same direction 

 exhibited by M. defoUarla, I think we may expect a similar advance 

 towards melanism from H. aurantiaria ; and it is in the West Kiding 

 Avhere it should l)e looked for, since that is the district where the 

 other members, nearest it in the genus, were first found to vary. 

 Hyhernia marginaria = progemmaria, Hb. — The dark purple form var. 

 J'nscata occurs abundantly at Y'ork and Huddersfield ; ])ut I have only 

 taken the intermediate suffused form at Horsforth, the species not 



* This is not particularly a northern form. It occurs at Mansfield, 

 Birminghanij Derby, in Staffordshire, and many other localities. — Ed.
