In  the  preceeding  Portuguese  paper  the 
authors  discuss  the  specimens  of  trypaneidae, 
found  in  the  collections  of  the  institute  of 
Manguinhos  and  of  the  museum  of  natural 
history  in  S.  Paulo,  and  describe  some  species 
and  varieties. 
The  most  important  form  is  the  Ana- 
strepha  (Dacus)  f rat  érenlas,  described  by  WIE¬ 
DEMANN  in  1S30.  He  included  it  in  the  ge¬ 
nus  Dacus,  LOEW  in  Trypeta  and  SCHINER 
in  the  genus  Anastrepha,  established  by  him 
and  now  generally  accepted.  It  is  known  to 
exist  in  Mexico,  Cuba,  Porto  Rico,  Peru, 
Brazil  and  Paraguay,  where  it  is  extremely 
injurious  to  guavas  and  peaches.  It  has  also 
been  found  in  the  fruits  of  Passiflora  qua - 
drangularis  and  the  recently  introduced  Dios- 
pyrus  kaki  from  Japan. 
The  species  is  evidently  a  very  variable 
one.  Several  of  the  forms,  described  as  new 
species,  are  likely  to  be  only  varieties.  This 
applies  to  A.  suspensa,  ludens,  hamata,  inte¬ 
gra,  consobrina  and  pseudo-pat  alíela  of  LOEW, 
obliqua  MACQUART  and  perhaps  peruviana 
of  TOWNSEND.  Even  parallela  WIEDE¬ 
MANN,  though  apparently  differing  in  size 
and  direction  of  the  long  veins  (as  pointed 
out  by  LOEW),  is  connected  by  intermediate 
forms. 
Variation  occurs  principally  in  the  design 
of  the  wing,  composed  of  three,  mostly  brown, 
bands  :  a  short  one  in  the  basal  half  of  the 
fore  margin,  another  in  the  shape  of  an  S, 
running  obliquely  through  the  wing,  and  a 
third  one,  like  an  inverted  V,  situated  near 
the  apex  and  beneath  the  second  one.  They 
are  interconnected  or  partially  obliterated  in 
varying  degrees.  The  different  forms  are  not 
geogaphical  varieties,  as  they  often  occur  in 
very  distant  regions. 
The  specimens  examined  represent  five 
new  types;  four:  Var.  A,  B,  C,  D,  correspond 
to  the  types  of  WIEDEMANN,  LOEW,  VAN 
DER  WULP  and  BEZZ1  and  one  is  similar  to
