varia) is certainly not a Oladura; I rather take it for a Limno- 
phila. There are two specimens from Loew’s collection in the Berlin 
Museum, a well preserved female and a fragment of uncertain sex. 
I am sure I perceive spurs at the end of the prosterior tibiae. The 
pubescence of the wings resembles that of Ulomorpha, but there are 
five prosterior cells; the second being very small. 
Lecteria 
noy. gen. 
A new genus, proposed for Limnobia armillaris (Fab.), Wied. 
Auss. Zw. I, p. 25, from Brazil. 
This is one of the forms of uncertain position between the Lim- 
nophilina and Eriopterina. It resembles {he former in general 
appearance and in the venation, but like the latter, it has no spurs on 
the tibiae. On account of its five posterior cells Lecteria may tem- 
porarily be placed near Oladura. The auxiliary vein runs very near 
the first vein and ends a very short distance before the tip of the 
latter; subeostal erossvein indistinet (I believe it must be found in a 
brown spot a short distance before the tip of the first vein, opposite 
the base of the first submarginal cell); marginal crossvein a very 
short distance before the tip of the first vein; the latter nearly op- 
posite the base of the first posterior cell; there is a supernumerary 
crossvein about the middle of the second submarginal cell, and in 
some specimens another one in the first posterior cell; five posterior 
cells; the second with a moderately long petiole; great erossvein at 
the base of the discal cell; antennae sixteen-jointed, Limnophila 
like; empodia almost rudimentary; ungues small, smooth; no spurs 
at the tip of the tibiae; male forceps of the type of those of Lim- 
nophila; ovipositor long, slender. 
The legs are rather stout, and very hairy; I have repeatediy 
examined with a strong lens the tips of the tibiae of several speci- 
mens of bsth sexes without detecting any spurs. — The approxima- 
tion of the tips of the auxiliary and first vein (as in Mongoma), is 
a very peculiar character, which isolates this form from the Lim- 
nophilina, even independently of the absence of spurs. —

This genus seems likewise to belong to the Limnophila-like 
forms with five posterior cells, but without spurs at the tip of the 
tibiae. The typical species is Limnobia irrorata Wied. A. Z. I,
