VARIATION. 183 



quite new to me, and much darker than anything I have previously 

 seen in this species. The following is a description of this form made 

 from one of the examples which Mr. Haggart has kindly given me, and 

 which I name harmarti. 



T.ENiocAMPA PULVEUULENTA AB. HAGGAKTi, 11. ab. — s Anterior wings uniform 

 dark brown ; the costal edge narrowly yellowish the outline of the reniform, and 

 orbicular, and the hindiiiarginal line yellowish, inclining to orange; the cilia 

 distinctly divided into a dark basal area and a rather paler outer area by a longitu- 

 dinal line. Posterior wings very dark grey, the basal area perhaps a little paler than 

 the outer area ; the cilia, grey intersected by a longitudinal line separating the 

 inner and darker from the outer and paler part. Thorax almost of the tint of the 

 forewings, but with a number of grey scales intermixed ; the abdomen of the same 

 dark grey colour as the hindwings. Galashiels. One example, March, 1901 ; three 

 examples, March '27th, 1902. All four j specimens on same sallow bush. 



It is to be hoped that Mr. Haggart will breed this form when 

 opportunity offers. I was struck, on first looking at the specimen, by 

 its superficial similarity in some aspects to one of the melanic forms 

 of CU'occrn riiiiinalU with which Mr. J. Harrison supplied our cabinets 

 some years ago, — J. W. Tutt. May 1th, 1902. 



Aberration of Aleucis pictaria. — I have an aberration of Aleucis 

 pictaria, taken here on April 19th last. The markings of the wings 

 are the same as in the type, but the whole colour of the moth, which 

 is usually of a smoky tint, is changed into butt'. I should like to know 

 if this form has been taken before. — (Miss) E. Miller, The Croft, 

 Rainsford Road, Chelmsford. Mai/ 2'drd, 1902. 



Aberration of Manduca atkopos. — I also have a fine Manduca 

 ativpos, bred in the autumn of 1901, which has the outer band in the 

 left hindwing very wide, and almost touching the inner band. The 

 outer edge of the wing itself has two curves instead of one. It is 

 quite a perfect moth and in no way crippled. — Ibid. 



Notes on Lasiocampa quercCs and L. var. callun.e. — Is there 

 any possible means of defining the difierences said to exist between 

 L. (jiierci'is and var. rallioiae ! I can find no real distinction except 

 that of habitat, and I am inclined to think that this is the only one. 

 I have read all the authorities to which I have access, and I have 

 obtained the opinions of many correspondents as well as those of the 

 members of the Birmingham Entomological Society. I have obtained the 

 larvae from various food-plants and difierent localities, and also imagines 

 captured by means of " assembling " and otherwise. They have come 

 from Jersey, Swanage, Starcross, Sutton Park near Birmingham, 

 Cannock Chase, &c., and from larvaj found near Goole. Placing 

 imagines from all these localities in a line with the so-called typical 

 L. (juercusat the top, and the well-marked var. callunae at the bottom, 

 one observes that a perfect gradation between the specimens, in spite 

 of the ditt'erence between the extremes, exists, and one is quite unable to 

 replace the specimens in their own sets again without reference to the 

 labels. One finds from larv* taken at the same time and place and 

 from the same food-plant, both forms represented, and every rule 

 that is laid down for their separation appears to fail when the 

 specimens are critically examined. For example, if we consider the 

 larvae obtained in this district, we find that they usually hatch in 

 August, they are then rarely to be seen till the middle of next April, 

 when they may be found in some seasons freely by searching the 

 heather, still in the second instar or just moulted into the third (easily 

 seen in the latter stage). They are best obtained from 10 a.m. until
