POLIA NIGROCINCTA. 



Plate LXXXVIII, fig. 5. 



On the 12th of July, 1876, Mr. Edwin Birchall, 

 then at Douglas, Isle of Man, kindly sent me a full- 

 grown larva of Polia nigrocincta, which I received on 

 the 13th at 3 p.m., and immediately began to figure. 

 Mr. Birchall informed me that it seemed to prefer 

 lettuce to its natural food, and was found eating green 

 seeds of dock, but seeing it had eaten out a flower of 

 thrift or sea-pink (Statice armeria), I provided some 

 for it, and it ate out several, more or less, during the 

 ensuing night ; some Plantago maritima was also 

 given, both leaves and seeds, but I am not sure that 

 it ate any, and, indeed, the larva seemed to be almost 

 or quite full fed, as it measured an inch and three- 

 quarters in length. It is moderately stout in propor- 

 tion and cylindrical, of nearly equal bulk throughout, 

 save that the last segment tapers as usual, and it 

 tapers also from the third segment to the head. The 

 head itself is glossy, brownish-red ; all the rest of the 

 body is soft and smooth, without gloss, the segments 

 plump and well-defined. The colour of the body 

 above is a peculiar brownish-red, and beneath, the 

 belly and legs are much of this colour but weakened 

 by a rather paler mixture of greyish-yellow, so that it is 

 less red than the back. The somewhat puckered and 

 inflated subspiracular stripe on the upper margin has 

 the inconspicuous spiracles ; these are of the general 

 ground-colour most finely outlined with blackish-grey ;
