46 ENTOMOLOGICAL NEWS. [March. 



The females of the later broods are usually lighter in color, 

 and in most cases with more pronounced bands on the wings. 



The band is sometimes almost yellow in contrast with a brown- 

 ish red wing, making a very attractive cabinet specimen. 



Often the hind wings are a shade lighter in color than the for- 

 ward ones, and occasionally there is a row of yellow points or 

 small spots beyond the band on this wing, and very rarely so on 

 the front wing. The more distinct band distinguishes the later 

 from the earlier female. 



This butterfly may be seen by the roadside, near its food-plant, 

 in sunny places, or about streams of water. The 9 is rarely met 

 with away from Croton, while the % wanders broadly. At some 

 damp place he may be found sipping, but it takes a clever hand 

 to capture him. At the slightest jar he darts into the neighbor- 

 ing tree tops with the rapidity of an arrow, and it takes a quick 

 eye even to follow him. He may come back, but his coming is 

 as sudden as his going, and before you have collected yourself 

 for a forward movement he is ofl" again, and he rarely settles in 

 the same place twice. With his wings folded, he defies detection 

 among the brown leaves or stones, and you must flush him before 

 you take him, and once flushed nothing but skillful manoeuvreing 

 can outwit him. 



The larva of Paphia troglodita feeds on both Croton capitabitn 

 and C. moncvithogynum, both of which grow here, often together. 

 The former, however, seems to be the preferred food-plant. In 

 one plant last August I counted twenty-five larvae of all sizes, 

 from those just hatched to those full grown. On another plant 

 sixteen.

Ninth Paper. — Classification of Insects. 



The number of kinds of insects is very great, so that no one 

 can hope to study minutely the structure, habits and transforma- 

 tions of but very few of them. But enough can easily be learned 

 about the various kinds in a general way, to know that the whole 

 great group of insects can be successively subdivided into smaller 

 and smaller groups. 



What we may call the unit in this subdivision or classification,
