than half the length of the entire body (PL xix., fig. 2, head, 

 antenniB, and proboscis with parts displayed.*) Palpi (apparently) 

 ■wanting. Antennae porrected, cylindrical, short, 2-+ 14-jointed ; 

 flagellar joints longer than broad, progressively diminishing in 

 thickness, with a microscopic pubescence. Thorax short, ovate, 

 very gibbose ; scutellum small ; metanotum large, acclivous. 

 Abdomen slender, somewhat compressed from the siJes, narrowed 

 at the base and extremity, seven-segmented ; terminal lamellse of 

 the ovipositor elongate-elliptical. Legs long and slender ; coxas 

 somewhat elongate, as in Sciara ; fore and interaiediate femora 

 slender, the hind pair dilated, a little longer than the other pairs ; 

 fore and intermediate tibiae and tarsi very slender ; hind tibise 

 incrassated towards the apex, nearly twice the length of the fore 

 pair ; hind tarsi thicker than those of the other legs. Fore tibise 

 with one, intermediate with tw^o very small spurs ; hind pair with 

 two unequal spui's ; no lateral s[)ines Wings shorter than the 

 abdomen, moderately broad, rounded oif at the base, incumbent 

 in repose ; microscopically pubescent. Costal vein extending much 

 beyond the tip of the third longitudinal vein, but not reaching the 

 apex of the wing \ auxiliary vein incomplete, very short, close 

 to the first longitudinal ; first longitudinal vein short, reaching the 

 costa considerably before the middle of the wing ; second longitu- 

 dinal wanting, possibly represented by a pale vein-like incrassation 

 between the first longitudinal vein and the base of the third longitu- 

 dinal ; no cross-vein between the longitudinal veins \ third longi- 

 tudinal vein originating at the base of the wing, tolerably straight, 

 terminating in the costa opposite the tip of the posterior branch 

 of the fork of the fourth longitudinal vein ; fourth longitudinal 

 incomplete, the petiole and base of fork wanting ; fork of fifth 

 longitudinal vein small, the anterior branch detached at the base \ 

 sixth longitudinal vein very rudimentary. 



Ohs. — The insect for which this genus is proposed reminds one 

 more of the Sciaridfe than of the Mycetophilidse, especially in the 



* The proboscis was originally filiform and somewhat bent in the dried 

 specimen before me ; its component parts were displayed as figured on 

 the application of moisture.
