a small white spot on the submedian vein at a third from the base ; a large subapical 

 vitreous space, on the costal margin, posteriorly shaded with lilacine ; the veins 

 crossing this space flecked with dark brown ; a whitish marginal line. Secondaries 

 white; at the base pinkish. Underneath the base of the primaries shaded with red. 

 Expanse, 33 mm. 



Habitat : Mexico to Brazil. 



Easily distinguished from B. specitlatis H. S. and B. trigona 

 Grote by the white spot on the collar and the marginal white line. 



Lophocampa andensis, sp. nov. 



Head brown; frons whitish. Thorax brown, the collar and patagi?e edged 

 with white. Abdomen brown. Primaries brown flecked with yellowish scales and 

 with four transverse rows of large white spots, the second row bifurcate from the 

 median vein to the costal margin ; fringe brown spotted with white. Secondaries 

 white; a brown spot at the apex. Expanse, $ 40 mm. 



Habitat: U. S. Colombia. 



I consider the following species as belonging to the genus Lopho- 

 campa Harris; caryce Harr., propinqiiens Hy. Edw., bicolo7- Walk., 

 agassizii Y2^ck., macidata Harr., and coiirregesiVxdgn. The following 

 species have two or three costal spurs on the secondaries ; subalpina 

 French, albigiitta Bdv., ainbigtia Strk.; minima Neum., has veins 3, 

 4 and 5, on the secondaries from a point; sobrina Stretch and li/gcns 

 Hy. Edw have veins 4 and 5 stalked on the secondaries and two costal 

 spurs. 



Edtoardsi Pack, and iabecitia Grote seem intermediate between 

 Lophocampa and Hatisidota. My observations have reference only to 

 those species which I possess. 



Halisidota typical will include tesselaris A. & S., with its forms 

 interlineata Walk., cinctipes Grote and atra Druce, also several species 

 described under Fhccgoptera, such as daraba Druce, ergana Dogn., 

 aconia H. S., and thalassina H. S. Many of the species placed under 

 Halisidota will require new genera,including the following species, which 

 I describe under that genus until I can obtain more material. 



Halisidota pulverea, sp. nov. 



Body chrome yellow. Primaries chrome yellow thickly covered with dark 

 striae and specks, confluent in places and forming an indistinct basal and outer line ; 

 a submarginal row of blackish points; a large black point at the end of the cell. 

 Secondaries yellow, a small brown submarginal spot between veins 5 and 6. Under- 

 neath whitish yellow ; some brownish stride on the costal and outer margins of the 

 primaries. Expanse, $ 42 mm. 



Habitat: Sao Paulo, S. E. Brazil. 



Belongs to the same group as strigulosa Walk., mandiis H. S.,
