three sub-median, and usually seven other, nervures. Body 

 slender. Legs long, and strongly spurred. 



The Pyrahs include a large series of moths of small size 

 and delicate structure. GueneVs "Deltoides et Pyralites" (1854, 

 cf. vol. iv. pp. xxx. 1 66), treated only of the typical Pyrales ; 

 the Crambi) which most authors now include in the same main 

 group, being omitted. He divided the former into a number of 

 families, chiefly based on European species. His arrange- 

 ment was severely criticised by Lederer, who published a 

 valuable series of papers on the Pyralidcz, very fully illustrated, 

 in the " Wiener Entomologische Monatschrift," vol. vii., for 

 1863. Lederer established some new families for foreign species, 

 but placed almost the whole of GueneVs series of genera in 

 a single family. Since then, entomologists have more or less 

 combined or rearranged Guenee's families, and various new 

 ones have been proposed for foreign species. In the case of 

 the Micro-Lepidoptera, it would be impossible for us to deal with 

 the families so fully as in the case of the Macro-Lepidoptera, 

 and we shall therefore only give a selection of some of the 

 more important genera, and indicate the families to which 

 they belong. 



GENUS CHRYSAUGE. (Chrysaugida^ 



Chrysauge^ Hiibner, Samml.Exot. Schmett. ii. pi. 156 (1824?) ; 

 Walker, List Lepid. Ins. Brit. Mus. ii. p. 367 (1854);

These are comparatively large and stout South American 

 moths, with short up-curved palpi, and rather broad black and 

 yellow wings. On the costa of the fore-wings of the male is a 

 rounded prominence, filled with hair beneath. 



Walker extended this genus to include the family which we 

 have already discussed under the name of Cyllopodida (antecl, 

 vol. iii. p. 1 86).
