39. Genus PSEUDOSCIARA, Schiner 
Pseudosciara. Schiner, Verh. Zool.-bot. Ges. Wien, Vol. 16, p. g3o (1866). 
Characters. — Head round; eyes reniform; front broad; ocelli two; antennae 2 + 10 jointed, 
the flagellar joints longer than broad, cylindrical, pubescent; palpi incurved, four jointed, stout at the 
base, the last two slender and long. Mesonotum moderately arched ; scutellum small. Abdomen cylin- 
drical, slender, thickh- pubescent, apical joint thickened. Legs quite long, coxae elongate; the femora 
shorter, the tarsi longer than the tibia ; fore femora as long or scarsely as long as the coxae ; tibial spurs 
long. Wings microscopic setulose, the costal margin with decumbent setulae, the posterior margin 
ciliate; subcosta \exy short, evanescent apically ; Ri ends in the costa far be3'ond the middle of the 
wing; basal section of the radial sector very short and transvejse in position ; R-M crossvein longitudinal 
in position and seeming to form the beginning of a longitudinal vein; media forks distad of the tip of 
the vein Ri, the petiole much longer than the fork, the branches widely separated; cubitus forks far 
proximad of the middle of the wing, the branches run close together near the base, then suddenly 
become more divergent. The form of the head and the course of the media reminds one oi Sciara, but 
the long coxas and the position of the fork of the cubitus show the relationship to the Mycetophilinae. 
Type species : P. hirtella, Schiner.

40. Genus MEUNIERIA, nom. nov. 
Willistoniella. Meunier (nec Mik), Mon. Mycetoph. etc. p. 74 (1904). 
Characters. — Antenna; apparently composed of fourteen joints, the apical joint with a minuie 
protuberance. Costa prolonged far beyond the tip of the radial sector; subcostal vein long and ending 
in the vein Rj at or before the proximal end of the R-M crossvein; R^ ends beyond the middle of the 
wing; basal section of the radial sector transverse in position, the apex ending in the costa far before 
the tip of the wing; media forks distad of the basal section of the radial sector, its anterior branch ending 
at the tip of the wing, the branches widely divergent; the cubitus forks at the base of the wing, the crotch 
obliterated (according to Meunier's figure); anal vein incomplete (PI. 5. Fig. 27). Joints of the palpi 
very robust, the first dilated, the second more slender but longer, the third about as long as the second. 
Type species : M. magnifica, ]\Ieunier. 
Geographical distribution of species : 
I. M. wia^wj^cfl, Meunier (fossil), Mon. Mycetoph. etc. p. 74, pi. 7, f. 2, 3 (1904). Baltic amber. 
The genus should doubtless be classed with the Sciaridae, but it is considered here for the sake of 
comparison, forming as it does a connecting link with the Mycetophilinae.
