cocoon in some crevice of the food-plant or elsewhere, 

 H. 23C(radoxa does tliis, I find, in tlie second instar ; Mr. 

 Fletcher found JI. pcnclla did so in the third. Whether 

 there is here a real specific distinction I cannot say, or 

 whether there may be an error of observation on my part 

 or on Mr. Fletcher's. The newly-hatched larva of penella 

 is certainly much smaller than that of 2^nradoxa. 



On all these points and some others my observation of 

 H.finradoxa yielded nothing that I had not already noticed 

 in the case of II. 2'>cnclla, and of these I do not propose to 

 go into any further details. 



The circumstance round whicli most of my interest in 

 II. ixiradoxa gathered, was in there being no less than 

 three forms or races of the species met Avith in the small 

 district in Spain we examined. 



Bejar, which ]\Ir. Cliampion and I made our head- 

 quarters this summer for three weeks, is in a granite 

 region, and is some 8300 feet above the sea. Above it 

 the Sierra de Bejar rises to a height of nearly 8000 feet, 

 and snow lay there in (piantity up to the end of Jul}', and 

 does so in places I believe throughout the year. Brooms 

 of half-a-dozen species are a very special feature of the 

 vegetation here. Genista florida very much beautified the 

 undergrowth in the neighbourhood of Bejar, but not going 

 higher than 4000 feet at the outside. On the Sierra, 

 Gytisus 2'>nrgans begins about 5000 feet and goes up to 

 nearly the top of the Sierra; it does not thrive or flower 

 freely at its lower levels, but at about 6000 feet we found 

 it forming dense masses of bloom covering thousands of 

 acres, and most plants were not simply sheets of bloom 

 but solid masses. Mr. Champion found, I think, that 

 with the beetles, it was an exceedingly marked feature of 

 the fauna that everything lived on the broom ; this fact 

 was not periiaps quite so striking in the Lc2nd(>iitcra, but 

 it was very marked. At any rate these brooms it was 

 that made Ilctcrogijnis imradoxa one of the notable 

 Lepidoptera of the region. 



The first evening of our arrival at Bejar, viz. June 2Gth, 

 I met with II. 2^ciradoxa, it was thenfully out, and occurred 

 close to Bejar at an elevation of about 3500 feet. The 

 males were most easily found by looking over the plants 

 of Genista Jlorida, on the more elevated and separate twigs 

 of which they were at rest, with their wings in some 

 degree curled round the twig. If disturbed slightly, they
