the forewing rather shorter, the two black median bands of the hindwing much 

 closer together, and the lines of the forewing more prominent. The tenth sternite 

 of the S narrower, the harpe distally much more rounded. In the ? the tubercle 

 behind the vaginal orifice smaller than in P. muscosa (the ? of P. s. sesquiplex is 

 not known). 



8. Protoparce diffissa mesosa subsp. nov. 



We have now a large series of specimens from Northern Argentina (Salta and 

 Tucuman). They differ markedly from the pale southern form P. d. diffissa, which 

 is found in the province of Buenos Aires, and resemble in colour more or less 

 P. d. petuniae from South-Eastern Brazil and Paraguay. They represent an inter- 

 mediate race, which as snch deserves a name, though it is not sharply separated 

 either from P. d. diffissa or P. d. petuniae. 



The upperside of the body and forewing generally as dark as in P. d. petuniae^ 

 but the forewing as a rule less russet. 



The underside of the abdomen shaded with fascous in nearly all specimens. 

 Intermediate between petuniae ^ind diffissa in size, but some of the specimens 

 larger than the smallest petuniae, and others smaller than the largest diffissa.

 J. Steinbach. 



9. Protoparce armatipes spec. nov. 



$ ? . P. licheneae simillima, sat minor, tarso antico extus spinis longis annate- 

 facile distingueuda. 



Hab. North Argentina : Tucuman and between the rivers Burmejo and Pilco- 

 mayo (J. Steinbach). Four <$ S and one ? . 



The first segment of the foretarsus bears four or five long spines on the outer 

 side, and the second segment one similar apical one. In colouring and markings 

 P. armatipes is almostly exactly like P. lickenea, but the basal area of the 

 hindwing, above, is more extended grey, there being a grey patch below the cell 

 extending from near the base to the inner black median band, this band being con- 

 sequently more prominent than in P. lickenea. The transverse lines of the forewing 

 are sharply dentate and strongly developed. The genitalia of the c? differ from 

 those of P. lickenea in the tenth tergite being slenderer and tapering more evenly, 

 and in the marginal teeth of the harpe being smaller. 



Ghlaenogramma undata R. & J. (1903) is similar in colouring and also has long- 

 spines on the foretarsus ; but it bears two black longitudinal streaks on the disc of 

 the forewing, and has no comb at the base of the midtarsus. 



10. Euryglottis guttiventris R. & J. (1903) 



We described this insect as a subspecies of E. ape?: But the material since- 

 acquired proves it to occur from Colombia to Bolivia, while E. aper is known to us 

 from Venezuela, Colombia, Ecuador, and Peru. The ranges of the two insects, 

 therefore, being almost the same, guttiventris must be considered independent of 

 E. aper. 



E. guttiventris differs from E. aper in the whitish marginal spots or borders of 

 the abdominal sternites being more distinct, in the pure black patches on the fore- 

 wing, above, being smaller in consequence of the development of a larger number of 

 transverse diffuse lines of raw umber-colour, in the creamy discal vein-streaks being
