and tenth segments which is strongly curved caudad and apparently 

 covered with some fine whitish setae, but this appearance may be due to 

 the fine striations present. The caudal margin of the furrow is crenu- 

 late. There is a very short cremaster present, bearing a small group 

 of hooked setae, which are more than half as long as the tenth 

 segment. 



The following species was examined :

SUPERFAMILY PAPILIONOIDEA 



The members of this superfamily are distinguished by the pos- 

 session of lobes indicating the presence of well-developed pilifers and 

 by their distinctly clubbed antennae. The genus Oeneis is an excep- 

 tion, however, in not having the lobes well developed ; but this is 

 probably due to specialization, as it seems very closely allied to the 

 Satyrinae; especially in the length of the prothoracic legs. Many of 

 the Papilionoidea have prominent ridges and tubercles on the surface 

 of the body, but there are also many genera in which the body surface 

 is quite smooth and destitute of tubercles and ridges. The epicranial 

 suture is present in three families, Megathymidae, Hesperiidae, and 

 Lycaenidae. There has been a great deal of discussion and disagree- 

 ment over the arrangement and subdivision of the families of the 

 Papilionoidea. Some have divided it into two superfamilies, Hes- 

 perioidea and Papilionoidea, but the pupae show no characters to war- 

 rant such a division. The family Lycaenidae has been considered by 

 many as the most specialized, or among the most specialized, of the 

 families, yet it still retains the epicranial suture. In this family, how- 

 ever, the labial palpi are entirely concealed except in the case of the 

 aberrant genus Feniseca, and the shortening of the prothoracic legs is 

 similar to the condition found in the Nymphalidae. It is impossible 

 without further study of existing forms and a larger series of species 

 to discuss fully the relationships between the different families. It is 

 sufficient for the present to state that the Lycaenidae seem more nearly 

 related to the generalized Hesperiidae, but have developed in a similar 

 manner to the Nymphalidae, and that the Pieridae, Papilionidae, and 

 Nymphalidae seem very closely related. The families of Papilionoidea 

 may be separated as follows : 



a. Proximo-lateral angles of the maxillae extending laterad to the eye- 

 pieces, 

 b. Maxillae never reaching the caudal margin of the wings ; wings 

 adjacent on the meson caudad of the maxillae. .Megathymidae.
