114 Dr. H. Eltringham on Specific and 



H. hecuba, Hew. 



This Colombian species also resembles a Titliorea. Seitz 

 regards both choarinus and cassandra as forms of this 

 species, together with tolima, Fassl. I have had hecuba, 

 choarinus and tolima to dissect, and they would certainly 

 appear to be the same species. The claspers of hecuba 

 and choarinus are shown on PI. XVI. That of cassandra 

 I have not been able to examine. 



H. hecalesia, Hew. 



The typical form occurs in Colombia and the form 

 formosus in Guatemala, Nicaragua, Costa Rica, and 

 Panama. I have dissected examples of both, and the 

 clasper is shown on PL XVI. It is of quite distinct structure. 

 H. octavia, Bates, has exactly the same type of clasper and 

 is certainly the same species. It occurs in Guatemala and 

 Honduras. 



Two forms of this group remain, H. gynaesius, Hew., 

 and H. longaremis, Hew. The first of these Riffarth 

 regards as a form of hecalesia. Unfortunately, I have had 

 no example to examine, and the only specimen of longaren us 

 known to me is the type. My view as to the position of 

 these two forms will be found under the consideration of 

 patterns. 



AOEDIFORMES. 



H. godmani, Stgr. 



This species is included by Rifiarth in the Aoediformes, 

 but its appearance suggests an alliance with gynaeskis, 

 though this may quite well be due to mimetic resemblance. 

 I cannot express an opinion as to its true position, as the 

 type is, so far as I know, the only specimen in existence. 

 It was taken on the river San Juan in W. Colombia. 



H. metharme, Erich. 



A rather distinctive-looking species occurring in N. Brazil, 

 Peru, Colombia, and doubtfully in Nicaragua. The male 

 armature (PI. XVI) is quite distinct from that of any other 

 form examined except aoede. 



H. aoede, Hiibn. 



The typical and three subspecies range through British 

 Guiana, N. Brazil, Venezuela, Peru, and Ecuador. The
