SATYRS.

covered with very minute but stiff bristles ; 

 the anal extremity is produced into two 

 parallel points directed backwards. The 

 colour of the head and body is either dull 

 olive green or dull pale umber brown ; in 

 either case the body has three compound or 

 triple stripes; one of these is dorsal, and 

 is composed of a medio-dorsal dark smoke- 

 coloured stripe, and two yellowish or whitish 

 marginal stripes, the dark medio-dorsal stripe 

 being in some specimens again divided by 

 a very narrow and indistinct white stripe ; 

 this median compound -vtripe terminates with 

 the twelfth segment; the other compound 

 stripes are lateral, composed of the same 

 colours, and terminating in the anal points. 

 Early in April the caterpillar spins a slight 

 silken covering on a stalk, stem, or blade of 

 grass, and, suspending itself therefrom by the 

 anal claspers, is changed to an obese CHRY- 

 SALIS, with the head broadly notched ; the 

 thorax, wiug-cases, and body are gibbose, and 

 suspended in an oblique position by numerous 

 small hooks at the anal extremity : the skin 

 of the caterpillar always remains attached to 

 the anal extremity, even after the butterfly 

 has escaped : the colour of the chrysalis is 

 dingy green or brown, the antenna-cases are 

 barred, and the wing-cases streaked with dark 

 brown or black ; the back is also freckled 

 with black, and has four or six white dots.

Obs. Sepp observed the young cater- 

 pillars to moult five times before hybernating, 

 namely, on the llth of August, when eight 

 days old ; on the 18th and 27th of the same 

 month ; and on the 4th and 15th of Septem- 

 ber ; and that they ate their own skins. 



TIME OF APPEARANCE. The caterpillar 

 may be found hybernating throughout the 

 winter, and full fed at the end of March ; 

 the chrysalis at the beginning of April ; and 

 the butterfly from the 10th to the 20th of 

 the same month. 



Obs. The opinion appears universally to 

 prevail that this species is double-brooded, 

 and in this (reasoning from analogy) I feel 

 inclined to concur, although I have never 

 an sestival brood of caterpillars, nor is 



such mentioned by Sepp ; but Lewin savs this 

 species "goes through its different changes 

 exceedingly quick, so that there are not less 

 than three distinct broods in the year ; " and 

 Mr. Doubleday informs me that this is in 

 exact accordance with his own observations. 

 LOCALITIES. I believe the Speckled Wood 

 to be distributed more or less abundantly in 

 every part of the United Kingdom, with the 

 exception of the Isle of Man and the north 

 of Scotland. Mr. Birchall says it is generally 

 abundant throughout Ireland ; Dr. Buchanan 

 White informs us it is " a very local species 

 in Perthshire, and never appears to be abun- 

 dant. It occurs on Kinnoull Hill and near 

 Muirhall, and is double-brooded. In Scotland 

 it has not been recorded beyond the north of 

 Argyleshire." Dr. White gives the following 

 dates of its occurrence: "1858, May 6; 

 1859, July 8 ; 1860, May 1 ; 1869, April 26 

 and August 8." I believe it occurs in every 

 English and Welsh county. Mr. Jenner-Fust 

 omits it from his seventeenth and eighteenth 

 provinces, comprising Wales : in both these 

 so-called provinces I know it to be very 

 plentiful.
