The  description  of  megastoma  BRAUER 
reminds  one  of  this  species,  but  the  illustra¬ 
tion  in  BALTs  monograph  looks  very  diffe¬ 
rent 
7.  Cuterebra  Schmalzi  n.  sp. 
(PI.  27,  fig.  3;  PI.  29,  fig.  3  (face).) 
Total  length  over  26  mm;  that  of  wing 
about  20  mm. 
Under  side  of  face  and  thorax  clothed 
with  yellowish  white  hairs,  which  extend  to 
the  superior  edge  of  the  antennary  pit  and 
form  a  narrow  band  at  the  edge  of  the  scu¬ 
tum.  Front  blackish-brown,  with  a  few  lighter 
intervals  ;  ocellar  tubercule  shining.  Ground 
of  scutum  grey,  turning  to  reddish  brown 
behind,  as  also  in  the  scutellum  ;  both  with¬ 
out  long  hairs.  In  the  center,  a  broad  vel¬ 
vety  streak  of  darker  color,  also  passing  on  to 
the  scutellum  without  reaching  its  apex. 
Each  side  shows  two  more  stripes,  but  they 
are  shorter  and  blurred,  specially  the  inner 
ones.  Between  the  central  and  the  lateral 
bands,  in  the  anterior  part,  a  rather  broad 
shining  white  triangle  and  other  similar 
but  shorter  spots,  between  the  lateral  stri¬ 
pes.  In  certain  lights  the  rest  of  the  interme¬ 
diary  space  also  seems  light,  though  it  shows 
much  less  distinctly.  Dorsum  of  abdomen 
thickly  clothed  with  silky,  reddish  golden 
hairs.  Both  specimens  have  a  central 
crescent  shaped  spot  of  dark  color  in  the 
first  ring;  its  convexity  somewhat  exceeds 
the  posterior  margin.  The  second  and  third 
segments  of  one  specimen  have  a  large,  api¬ 
cal,  velvety  black  band,  which  crosses  the 
whole  dorsum  and  ends  in  a  point  at  the 
ventral  extremity.  In  the  other  specimen, 
there  is  only  a  broad,  crescent  shaped  spot 
on  the  apical  margin  of  the  second  article  ; 
its  convexity  is  directed  forwards,  and,  at  its 
broadest  (in  the  median  line),  it  hardly  covers  | 
half  the  ring. 
Abdomen  very'  thick,  convex  in  two  direc¬ 
tions. 
Legs  brown  with  a  tinge  of  red,  black 
cilia,  and  a  few  short  yellow  hairs,  at 
rhe  base  only.  Wings  pale  sepia  brown,  the 
basis  redder;  alulae  darker.  Thoracic  squama 
large,  brown,  with  lighter  edge,  and  dark 
rim  inside. -The  specimen  with  the  dark 
bands  seems  to  be  a  male;  its  eyes  are  har¬ 
dly  larger,  but  the  antennal  pit  is  narrower, 
and  the  last  article  undimpled.  Unfortunately 
this  segment  is  wanting  in  the  other  speci¬ 
men. 
This  very  conspicuous  species,  is  dedi¬ 
cated  to  the  late  entomologist  JOÃO  SCH- 
MALZ,  from  Joinville,  who  collected  these 
and  two  other  specimens.  (Note  :  These  have 
also  been  offered  to  our  collection.' 
II.  Genus  Rogenhofera. 
10.  Rogenhofera  dasypoda  BRAUER. 
(PI.  28,  fig.  8.) 
BRAUER  established  the  genus  Rogenho¬ 
fera  in  1863,  giving  a  very  detailed  des¬ 
cription  of  it  in  “Verh.  d.  k.  k.  zooi.  bot. 
Ges."  in  Vienna,  which  was  reprinted  in  his 
monograph.  I  shall  not  reproduce  it  here,  but 
give  the  translation  of  another  detailed  des¬ 
cription,  which  tallies  with  the  characters  of 
the  species  observed  by  me.  There  are  three 
known  species-  The  first  described  swa 
grandis  GUER. ,  from  Patagonia ,  which  was 
placed  amongst  the  Cephenomya ,  but 
withdrawn  later  on  by  BRAUER.  CARLOS 
BERG  thinks  it  was  the  same  species  that 
he  observed  near  the  capital  of  the  Argen¬ 
tine  Republic.  He  considers  it  a  typical  Ro¬ 
genhofera  and  describes  both  sexes,  as  well 
as  the  larva. 
The  type  is  Rogenhofera  trigonophora, 
from  Bahia;  it  was  described  and  illustrated  by 
BRAUER,  and  has  apparently  not  been  found 
again.  Later  on  BRAUER  described  another 
species,  R.  dasypoda,  from  Espirito  Santo.  The 
following  is  a  translation  of  his  description  : 
“Large  entirely  black  species,  save  for 
the  reddish-yellow  arista  and  shiny  brownish 
tomentum  on  the  lower  side  of  the  hind 
tarsi.  The  last  segments  bear  a  few  yellow 
hairs.  Vertex  half  the  width  of  head  (about 
3  mm.),  clothed  to  the  margin  with  short 
black  hairs  ;  getiae  shiny,  almost  bare  from 
the  level  of  the  base  of  the  antennae;  at  the
