1923] Two New Species of Fhoridoe from Baltic Amber 59 
TWO NEW SPECIES OF PHORID^ FROM BALTIC 
AMBER.^ 
By Charles T. Brues. 
Some years ago, while examining a small series of amber- 
insects, now in the collections of the museum of the University 
of Konigsberg, I chanced upon a beautifully preserved specimen 
of the family Phoridse. This species, which is described below as 
Dohrinphora transita is in a small piece of amber together with 
an hymenopterous insect representing an undescribed genus of 
Bethylidse. A second species included in the same lot proves 
also to be new. 
The occurence of Phoridse in Baltic amber was noted many 
years ago by BehrendF and soon afterwards Loew® mentioned 
the existence of eleven species of this family in amber that had 
passed through his hands. Much more recently the present 
writeF has described two species from the Miocene shales of 
Florissant Colorado. In 1909 MeunieF described and figured 
a number of species from amber. Unfortunately, it is very 
difficult to recognize his species as the descriptions are based to a 
great extent upon characters not generally used, and many 
important diagnostic characters are not included. In spite of 
these difficulties I am quite certain that the two species des- 
cribed below are different from any of those dealt with by 
Meunier. 
The first one differs from all previously known species by 
the presence of a broad, flattened enlargement before the tip of 
the third longitudinal wing vein, a character which seems to 
form a transition between the recent species of Hypocera and 
those of the more generalized genera with forked third vein, 
since a number of species of Hypocera show a very similar 
swelling at the tip of the third vein. They lack the second vein, 
however, which is present in the fossil species.
