A CHAPTER ON ZYG^NA MINOS. 61 



occurs later with us than about the middle of May. The 

 larva of the above-mentioned variety or species, which flies 

 in the perfect state in August, when 3Iinos is long past, I 

 had for several years sought in vain. I find them only on 

 Thymus Serpyllurrij on sandy places in fir-woods, never in 

 our fortification trenches, where Minos is in many years 

 quite common. This year I found a larva on the "21st June, 

 v^iiich. for want of proper care, died. But immediately I 

 found it I made the following description of it. 



The larva is dark citron-yellow — at the end of each ring 

 are two black spots, which consequently form a double row 

 of spots, between which are numerous white hairs, placed on 

 extremely fine blackish warts. Along the legs is placed, in 

 the middle of each segment, a small black spiracle, over and 

 under which are white hairs, as on the back. A careful 

 comparison with the larva of the ordinary Zi/gcena Minos 

 must be postponed, as I have neglected to seek for larvae at 

 the right time.
