FAM. MYCETOPHILID.^: g3 
48. Genus PAL/EODOCOSIA, Meunier 
Palseodocosia. Meunier, Mon. M_ycetoph. etc. p. i6i (1904). 
Characters. — Antennae longer than the head and thorax (female), two basal joints differentiated, 
flagellar joints cylindrical, those near the base about twice, toward the apex becoming three times as long 
as broad, short petiolate, apical joint longer than the preceding; the first three palpal joints short, the 
fourth longer than the three taken together. Costa produced beyond the tip of the radial sector; subcostal 
vein joins Rj beyond the middle of the basal cell R which is long and broad; basal section of the radial 
sector nearly transverse in position, shorter than the oblique R-M crossvein; petiole of the media rather 
short, but little if any longer than the R-M crossvein ; cubitus forks proximad of the base of the fork of 
the media; anal veins incomplete (PI. 6, Fig. 8). The last four tarsal joints of the fore legs much 
dilated. The basal lamellse of the ovipositor rather long and rectangular, the apical part small, rounded, 
ciliated. 
This genus bears a close resemblance to, and may not be distinct from Syntemna, but because of 
the difficulty of observing the ocelli in fossil specimens it is impossible to say with certainty that they 
are identical.

49. Genus PAL/EOTRICHONTA, Meunier 
Palseotrichonta. Meunier, Mon. Mycetoph. etc. p. 16S (17) (1904). 
Characters. — Antennae as long as head and thorax taken together (female), the joints longer 
than broad, the two basal joints differentiated, flagellar joints cylindrical, slightly petiolate, apical joint 
conical. Palpi four jointed, fourth joint a little longer than the third. Legs stout, the tibiae and tarsi 
ciliated. Ovipositor stout, the lamells! at the apex small, rounded, ciliated. Costa but little prolonged 
beyond the tip of the radial sector; subcostal vein joins Ri distad of the middle of the basal cell R which 
is large; R-M crossvein longer than the basal section of the radial sector; petiole of the media but little 
shorter than the R-M crossvein; cubitus forks proximad of the pro.ximal extremity of the R-AI crossvein, 
anal veins incomplete (PI. 6, Fig. 9). 
A fossil genus doubtfully distinct from Trichonta; the wider basal cell R and the retracted position 
of the fork of the cubitus are scarcely of sufficient importance to warrant generic separation.
