ginal white streaks (near ab. nii/ra, Raynor), right side tj'pical. Thorax 

 and abdomen perfectly halved. The inheritance of ab. /;////« does not 

 seeu) to be a simple Mendeiian one. This halved example was bred by 

 R. Tait, jun. {.Journal of (jrenetioi, 1915, v., p. 87, pi. xxi., fig. 2.) 



iJiibera jxiuiria, L. Sex not mentioned. One side typical, the other 

 var. rotnndaria, Haw. Both typical specimens, and those of the variety 

 were bred at the same time as this abnormal one. {I'ror. South Loud. 

 EtU. and N. H. Soc, 1891, p. 137.) 



Arctia caia, L. Left side typical, right side melanic with both 

 wings completely brownish black, ab. obscura, Cockerell. Bred from a 

 Huddersfield larva. (]\Iosley, Varii'tiea of Britisli LfjAdoi)tera, (Jlielonia, 

 pi. vi., fig. 3.) From the figure this appears to be a female. 



Arctia rata, L., female. A similar speciuien in the W'iskott collec- 

 tion. (Standfuss, tJandlnirh I'aliiarkt. (rrosfi. Sr/iinett, p. 206.) 



Arctia caia, L. Left side typical, right side melanic, ab. obscnra, 

 except for a small patch of typical colour at the apex of the hindwing. 

 Tring Museum. The melanic ab. obscnra is well known, but rare. 



Arctia caia, L., female. Right forewing much whiter than left. 

 Right hindwing with the dark spots feebly marked and confusedly 

 united with one another, approximating to var. confiaeus, Rbl. Left 

 side normal. Frings, 1897, Bonn. {Illtiatr. Zcitsc/ir. f. Knt., 1900, 

 v., p. 73.) 



Arctia rillica, L., female. Right side normal, left with all the black 

 markings replaced by creamy white, hindwing of the usual rich yellow, 

 but with the black markings not quite like those of the other side. 

 Thorax with right half black, left half creamy white. (0. Schultz, 

 Ent. Zeitschr, Stuttgart, 1906-1907, xx., p. 26.) 



Arctia rillica, L., female. Right side typical, left forewing all 

 yellowish except for a black stripe along the costa, a black discal spot, 

 and black spotted fringe. Left hindwing yellow all over, except for a 

 black fringe at apex. Base of left antenna yellow, femora and tarsi of 

 second and third legs yellow. Abdominal spots on left side paler and 

 fewer. The aberrant side is near ab. illiistris, Schultz. {Berl. Knt. 

 Zeitschr, 1888, xxxii., p. 495, Taf. vii.; and Ent. Zeitschr, Guben., 

 1904, xviii. p. 114.) Specimens of villica with both sides resembling 

 the aberrant side of these two are known, but are very rare. Their 

 pale colour is not due to absence of pigment or defect of scales. 



Zijija'na fiUpendnhr, L. Right side typical, left with spots united 

 and forming three wedge-shaped blotches, ab. tririttata, Tutt. (Tutt, 

 Brit. Le/iidopt., vol. i., p. 509.) Sex not mentioned. 



Z. fdi]>endid((', L. Right side typical, left with all the spots con- 

 fluent (?ab. conjirncta, Tutt). Y. E. Shaw, JJ>over, 1910. (Trans. City 

 of Lond. Ent. Soc, 1911, p. 5.) The sex is not recorded, but I have 

 examined the specimen with a microscope, and the shape and size of 

 abdomen and the external genitalia are female. The wings on the two 

 sides are equal and perfect. Confluent aberrations are not very rare at 

 Dover, 



Z. /ilipendiiLc, L. Confluent on left forewing only. Sex not 

 mentioned. Joicey coll. (Entoinolotjist, 1917, L., p. 45.) 



Z. loniceric, Scheven. Spots on left fore^ying confluent, separated 

 on right. Sex not mentioned. (Oberthiir, Etudes. Lep. Coinp., 1910, 

 v., p.. 514 ; and Tutt, llrit. Lej>ido/>t., vol. i., p. 4G9.) Confluent 

 aberrations are uncommon in this species.
