340 Mv. A, G. Butler on Heterocerous Lepidoptera 



That it may be seen that I do not speak without 

 reason, I shall just give one instance of an utter dis- 

 crepancy between the Latin diagnosis and the Spanish 

 description of the same insect ; M. Blanchard, describing 

 the secondaries of his Larentia triangularia (which by 

 the way is probably not a Larentia at all), says first of 

 all, after mentioning that there are two little sinuated 

 lines across the primaries, "posticis, Unca simillima" ; 

 but in his description he says, "las alas posteriores 

 redondeadas igualmente con dos lineas transversales." 



Such inaccuracies as the above, although they may 

 not in all cases prevent the student from recognising his 

 species, must at least give him a considerable feeling of 

 insecurity as regards the correctness of his identifications, 

 and particularly when the species apparently best suited 

 to a description belongs to a family widely distinct from 

 that in which the author before him has placed his 

 insect ; if, therefore, I have erred either in my identifi- 

 cations or non-recognitions of M. Blanchard's species, 

 I can only say that the fault lies with that author and 

 not with myself. 



Very few species have been described since the pub- 

 lication of Gay's work, even Walker not having touched 

 them, at any rate so far as the present collection is con- 

 cerned : the greater number of additions has been made 

 by Felder and Kogenhofer in the ' Eeise der Fregatte 

 Novara.' 



The following is a list of the species : — * 



UEAPTEBID^. 



GONOGALA, n. g. 



Allied to Urapteryx, but the wings of the same form 

 as Tetrads ; the antennae and coloration corresponding 

 with Metrocampa margaritata : wings rather narrow, 

 with angulated outer margins ; body extremely slender, 

 hardly extending beyond the secondaries ; antennae 

 finely pectinated on both sides; palpi very small, 

 scarcely extending at all in front of the head ; anterior 

 tibiae with lateral internal appressed pencil of long 

 hairs ; both legs and proboscis long and slender. 



* Mr. Edmonds informs me that the focahty "Las Zouas" 

 shoukl be written "Las Zorras"; in Enghsh, "The foxes." It is 

 a small subm-b of Valparaiso.
