Polydama and Typhon on being taken in the county of Yorkshire, and sent 

 to him by P. W. Watson. Both / lydama and Typhon were taken on the 

 21st July, 1809, by the Rev. W. T Bree, on the moors between Bald and 

 Festiniog in North Wales ; and Curtis records Typhon as being taken plenti- 

 fully by himself and Mr. Dale in Jul , 1825, in the Isle of Arran.

The wings of this, our smallest Bi tish representative of the family, expand 

 from the width of from a little mor than one inch to nearly an inch and a 

 half. On the upperside they are of a fulvous, or pale tawny colour, with 

 brown margins, and a black spot near the tip of the fore-wings. In the 

 males, the dusty edging of the wings is more decided than in the females. 

 On the underside the fore- wing resembles the upperside, but the spot is much 

 more distinct, being white centred, and in a yellowish ring ; the hind-wings 

 resemble those of Typhon without the ocelli, having in their place minute 

 white dots. Varieties occur in which the ocelli on the underside are bipu- 

 pilled, and others in which they are entirely wanting, sometimes also tlie 

 upperside is without the spot. One, in my collection, taken by Mr. Paul, 

 at Langport, in Somersetshire, is of ;i whitish yellow tint, which makes the 

 dark border appear very distinct, Another I have, has the ground colour 

 very much darker than the type, similar to Philoxenus. In the large South 

 European variety Lyllus, Esper, there are faint traces of marginal eyed spots. 

 The egg is somewhat bucket shaped, with flattish base and top, and up- 

 right sides, broader at the base than above ; the sides with nearly fifty small 

 irregular ribs, and faint transverse reticulation, the top thimble-pitted all over, 

 the shell glossy, pale green at first, turning in a day or two to whitish, freck- 

 led and ringed with pale yellowish brown. (Rev. J. Hellins, in Appendix 

 to " Buckler's Larvae.") 



The caterpillar is of a bright green colour, with dorsal line of a darker and 

 spiracular line of a lighter shade, and pink anal points. It feeds on Poa 

 annua, Cynosurus cristatus, and other kinds of grasses. 



The chrysalis is suspended by the tail to a blade of grass. It is of a bright 

 green colour, with minute white spots, rather broad and blunt at the head. 

 At the end of the tail is a short, stout, rather flattened and curved spike, the 

 tip of which is thickly set with curled spines, well adapted for holding on to 

 the silk pad,
