therefore certainly a mere typographical error, which I 

 have removed.

18. Pybausta, Schrk. 

 Face rounded ; ocelli distinct ; tongue developed. Antennae two- 

 thirds to tbree-fom-ths, in $ filiform, ciliated (| — 2) or rarely naked. 

 Labial palpi moderate, porrected, second joint with dense pro- 

 jecting scales attenuated to a point forwards, terminal joint con- 

 cealed. Maxillary palpi moderate, porrected, apex loosely peni- 

 cillate. Abdomen in ^ with moderate anal tuft. Middle tibiae in 

 (^ sometimes dilated, enclosing tuft of hairs in groove ; posterior 

 tibiae with outer middle-spur one-third to two-thirds (rarely one- 

 fifth), outer end-spur one-half to three-fourths of inner. Fore 

 wings with vein 7 from near 9, 8 and 9 stalked, 10 closely approxim- 

 ated to 9 towards base, rarely anastomosing with 9. Hind 

 wings over 1 ; veins 3, 4, 5 more or less approximated at base, 

 7 out of 6 near origin, anastomosing with 8 to one-third to two- 

 fifths. 



Although representatives of this genus are found 

 nearly everywhere, it is mainly characteristic of the 

 temperate regions of the northern hemisphere, and is 

 probably of European origin. The occasional anastom- 

 osis of veins 9 and 10 of fore wings is a curious form 

 of variation, found also in Evergestis ; no use can be 

 made of it in classification, as both forms occur in diffe- 

 rent individuals of the same species, or even in different 

 wings of the same specimen. The species in which I 

 have noted this form of variation are trinalis and decrepi- 

 talis, but it may probably occur more or less rarely in 

 others also. Hence the Hawaiian genus Protocolletis, 

 Meyr., which was founded essentially on this character, 

 should be suppressed.
