found among bushes in hilly districts throughout Southern and 

 Central Europe. Its flight is weak, and it is usually seen in 

 open places, such as a sunny drive or a glade, never flying far, 

 and apparently restricted to a narrow area, probably in the 

 vicinity of the food-plant. 



Exotic genera of Nemeobiince. 



Most of the Asiatic and African species of Nemeobiina, except 

 those belonging to the two following genera, are considerably 

 larger than our European species. The Central Asian genus 

 Polycana most resembles Nemeobius in general appearance, 

 and the species are likewise very similar to small species of 

 Melitcea. They are brown Butterflies, with more or less con- 

 fluent tawny or reddish markings on the fore-wings ; the hind- 

 wings have a double row of spots, the sub-marginal row tawny, 

 or reddish, and the inner more yellowish. The under side 

 is dark brown, with a sub-marginal reddish line, and with 

 more or less extensive fulvous or pale yellow markings on the 

 fore-wings, and pale yellow or whitish markings on the hind- 

 wings. They are not much larger than Nemeobius ; nor is 

 Stiboges nymphidia, Butler, a Butterfly very dissimilar to the 

 Fritillaries in colour, which is found in Western China, Bhu- 

 tan, Penang, &c., and which is remarkable for its superficial 

 resemblance to some of the South American Lemoniidce, It is 

 dark brown, with a very broad white band covering the hind- 

 wings, except at the extreme base, to beyond the middle, and 

 extending over the fore- wings nearly to the costa, except at the 

 base, and across and beyond the lower part and end of the cell. 



We may mention most of the principal tropical forms of this 

 Sub-family, as they are not very numerous. The genus Zemeros, 

 Boisduval, contains two or three species, common in the East 

 Indies, generally measuring rather less than two inches across 

 the wings, which are more p.r less dentated, and sometimes;
