Dartmoor Notes—Zygena trifolii and other species. 
By G. T. BETHUNE-BAKER, F.L.S., F.E.S. 
In November, 1914, Commander Walker exhibited at the meeting 
of the Entomological Society of London, on behalf of Dr. R. C. L. 
Perkins, two beautiful series of Zygaena trifolii from two separate 
colonies not more than 200 yards apart. The one series was composed 
of fine robust specimens with the spots all separate, or at least only 
the two median ones confluent, the other series was composed of small 
specimens with a large percentage of examples, in which all the spots 
were more or less confluent. A yet more interesting point was the 
fact that the two colonies though so near did not intermingle. 
I have visited Dartmoor regularly for over twenty years, always 
once and generally twice every year, and in all my many peregrinations 
and in all my sojourns there, often for weeks together and always in 
the right season, I have never come across so deeply interesting a case. 
I have, of course, known places where ¢trifolii occurred and also equally 
likely spots, where it did not occur, so that Dr. Perkins’ exhibition 
imbued me with the resolution to investigate the matter. 
Fortunately for the species, the two colonies referred to are on 
private ground that is strictly preserved and guarded; with some 
difficulty, however, Dr. Perkins was able and was good enough to take 
me to the spot last summer. The large colony, or rather the colony 
of the large race, was in full evidence and very vigorous, and we took 
thirty-four specimens from it, of which nineteen were quite typical with 
the median spots confluent, the united spot being in most instances 
large, but in no case were all three sets of spots confluent; fifteen, 
however, had all the spots separate. In two cases out of the nine- 
teen a small red dot lies between the median and the outer single spot, 
in one specimen—a large one—the median and the outer spots are 
confluent in one wing only, viz., the right wing; in another example 
the same thing occurs with the addition in both wings of a prolonga- 
tion of the lower median spot towards the lower basal spot, whilst in 
yet another specimen both the lower median and basal spots are pro- 
longed towards each other and are united by a fine dash of red scales, 
whilst between the outer single spot and the median pair of the right 
wing only a small but distinct red dot is present. 
Taking into consideration these six specimens out of the thirty- 
four, we find no less than 17%, or more correctly nearly 18%, are in a
