longer than the ectoprocts in curriei, by the parameres, 
which are not formed as hooks, like those of curriei , and by 
the evenly infuscated femora — dotted in curriei. It is 
much more robust than brunneus, the ectoprocts of which 
have a preapical lobe on the median side, and the femora 
of which are dotted. 
Tyttholeon, new genus 
Figures 7, 8, 11, 12 
Belongs to the Brachynemurini. 
Labial palpi short, apical segment not swollen; antennae 
stout, strongly clavate. Legs fairly stout, tibial spurs ab- 
sent, first tarsal segment two-thirds length of next three 
together. Abdomen much shorter than wings, of same 
length in male as in female. Many long white setae present 
on femora, coxae, and thorax (except metanotum). 
Fore wing : costal area narrow, the cells more than twice 
as long as high; Rs+MA originates only slightly proximal 
to cubital fork; cubital fork acute. A x straight, connected 
to CuA 2 by one or two cross veins ; A 2 unbranched ; A 3 fork- 
ed near margin. Banksian lines absent. Hind wing: costal 
area narrow; only one row of cross veins between cubital 
veinlets; CuA 2 reaches margin before CuF; at most one 
cross vein between CuAt and CuA 2 beyond fork. Banksian 
lines absent. Pilula axillaris present in male. 
Tyttholeon is most likely to be confused with Maracan- 
dula Currie, since both of these genera lack spurs. In Mara- 
candula, the first tarsomere is longer than the following 
three together. The venation is much less dense in Tyttho- 
leon , and Rs+MA originates farther out on the wing; in 
Maracandula the costal cells are higher than long. The 
white setae on legs and thorax are not nearly so long as the 
macrochetae of Maracandula. There is no similarity be- 
tween the internal genitalia. Maracandula (Figures 9, 10) 
has on the paramere a lateral, heavily sclerotized ligulate 
lobe, and a sharp ridge on the posterior face. In T. puerilis 
the parameres are folded in a complex manner, but have no 
conspicuous heavily sclerotized hooks or lobes.
