communication  by  JOSEPH  BISCHOF,  me¬ 
dical  student:  “Preliminary  characterisation 
of  some  genera  of  Muscaria.” 
I  give  only  the  passage  which  refers  to 
Pseudogametes  : 
“ Pseudogametes  n.  gen.  It  differs  from 
Cuterebra  by  its  arista  which  is  pennate  on 
both  sides  and  also  from  Rogenhofera  BRAU. 
and  Bogeria  AUST. ,  which  have  bare  aristae. 
Type  :  Hermanni  n.  sp.  ;  <S  from  Minas 
Geraes.  Length  16,8  mm. 
It  is  in  every  way  so  like  Rogenhofera 
dasypoda  that  it  might  be  taken  for  the  male 
of  this  species.” 
At  another  meeting  (N.  XV.  page  155.) 
F.  BRAUER  presents  another  notice  by  the 
same  author  under  the  title:  Some  new  ge¬ 
nera  of  Muscidae.  (This  does  not  seem  to 
have  been  printed.) 
The  type?  of  these  genera  are  in  the 
Hofmuseum  in  Vienna;  Pseudogametes  was 
sent  by  Prof.  HERMANN  in  Erlangen. 
I  give  the  following  description  of  the 
genus  which  is  based  on  a  study  of  the  two 
known  species: 
Large,  stout  and  very  hairy  flies,  with  thick 
and  broad,  ciliated  legs.  Head  and  abdomen 
depressed,  so  that  the  axis  of  the  body  seems 
curved  when  seen  from  the  side.  The  fa¬ 
cial  profile  is  not  convex,  but  the  margins 
of  the  antennary  pit,  especially  the  lower 
one,  are  very  prominent.  The  hairy  front 
protrudes  between  the  eyes,  when  it  is  looked 
at  from  above  ;  the  rest  of  the  face  forms  a 
continous  callosity  covered  with  long  but 
isolated  hairs  ;  genae  and  malae  separated 
by  a  gutter  like  depression.  The  whole  body 
especially  the  very  prominent  scutellum  is 
clothed  with  long  non  ramified  hairs.  Wings 
dark,  with  large  lobules  and  open  apical  cell  ; 
angle  of  transversal  apical  vein  sometimes 
with  short  appendix  ending  in  a  fold 
of  the  membrane;  the  fifth  vein  very  often 
reaches  the  margin,  but  the  piece  outside 
the  transversal  vein  is  very  much  reduced 
and  sometimes  very  difficult  to  see,  only  the 
base  being  distinct.  Antennal  groove  very  ex¬ 
cavated,  median  ridge  obliterated,  the  ground 
in  its  upper  part  sligh-ly  dusty,  for  the  rest 
shining,  sometimes  a  little  wrinkled.  Third 
antennal  article  undimpled,  much  longer  than 
the  other  two  together,  closely  applied, 
whereas  the  pennate  arista  is  salient,  with 
more  outstanding  upper  hairs.  Eyes  small, 
but  very  convex;  in  the  female  they  are  of 
the  same  size  but  set  wider  apart.  This  genus 
differs  from  Rogenhofera,  not  only  by  the 
arista  but  also  by  the  shape  of  the  antennary 
pit  and  the  head. 
12.  Pseudogametes  Hermanni,  Bischof, 
1900. 
ÍPI.  28,  fig.  7). 
I  have  two  specimens  of  this  species  ; 
their  size  and  uniformly  black  color,  agree 
with  BISCHOF’s  indications.  (The  rest  of  the 
characters  can  be  taken  from  the  description 
of  the  genus.)  They  were  caught  in  the 
North-West  of  São  Paulo,  on  a  tree,  at  a 
good  height  from  the  ground,  and  evidently 
have  habits  very  similar  to  those  of  the  fol¬ 
lowing  species  : 
13.  Pseudogametes  semiater  WIED. 
(Musca  semiatra  WÍED.) 
We  give  the  original  diagnosis  and  an 
english  translation  of  the  description  : 
“Capite,  thoraceque  atris,  scutello  abdo- 
minisque  tergo  rufis  ;  antennis  sub  fronte  se- 
mioccultis.  - 11.  From  Brazil. 
“Head  deep,  black,  irons  large,  protru¬ 
ding  in  front  above  the  antennae,  so  as  to 
half-hide  them,  shining  at  the  sides.  Under 
face  very  much  depressed  below  the  annte- 
!  nae,  the  anterior  edge  sloping  considerably, 
the  sides  clothed  with  black  hairs.  Ground 
color  and  hairs  of  thorax  deep  black;  scu¬ 
tellum  thickely  clothed  with  long  reddish- 
yellow  hairs.  Dorsum  of  abdomen  with  thick 
reddish-yellow  pile;  venter  deep  black.  Wings 
blackish-brown,  venation  as  in  Musca.  Squa¬ 
mae  blackish  brown.  Legs  black.  Obtained 
from  Dr.  LUND”. 
Though  WIEDEMANN  hinted  that 
this  fly  belonged  to  some  new  genus,  he 
did  not  connect  it  with  Trypoderma  ( Cute¬ 
rebra )  or  other  Oestrinae.  His  specimen,  pro-
