THE LULWORTH SKIPPER. IQI 



prolonged as far as the middle of the head, and run to the 

 end of the flat anal shield, which is narrowly" edged with pale 

 yellow. The head is greenish with two yellowish lines. The 

 two snow-white patches on the under side of the ninth and 

 tenth rings of the body are conspicuous as in lineola^ sylvanus, 

 and comma. This white substance is spread out at the tail end 

 of the caterpillar of actceon, when it has formed its chrysalis 

 case (Zeller). 



Buckler, referring to four caterpillars found on Br achy ft odium 

 sylvaticum, June n, states that they completed their growth 

 on a diet of Triticum repens. They ate out wedge-shaped 

 portions from the sides of the grass blades, and when they had 

 finished their repast, they crawled down to the middle of the 

 blade, and there spun a coating of white silk from one side to 

 the other, causing the two edges of the blade to draw together 

 a little, and then in the silk-lined hollow they rested until 

 hunger obliged them to ascend the blade again for another 

 meal. About June 23 they had ceased to feed, and were begin- 

 ning to fasten themselves within more closely constructed 

 retreats, formed where two blades of grass obliquely crossed 

 each other. The colour of the chrysalis is similar to that of 

 the caterpillar, and the lines are faintly traceable. The butter- 

 flies appeared July 14 to 18, emerging at night, and ready for 

 flight in the morning. 



This insect received its English name in 1832, when it was 

 first discovered in this country at Lul worth Cove, in Dorsetshire. 

 It has since been found to occur at Durdle Cove, and the 

 Burning Cliff, Weymouth, and the latter locality appears to be 

 its most eastern limit. Its range extends westward along the 

 coast of Dorsetshire and Devonshire to Sidmouth, Seaton, and 

 Torquay ; and there are records of its having been observed 

 in Cornwall. According to Mr. E. R. Bankes, as quoted by 

 Barrett, this butterfly is not confined to the coast line in Dorset, 

 but is to be found in two or three spots along the chalk range
