commissure near apex of elayus. Hind-wing more than half the length of 
tegmen, anal area well developed with anal veins. 
Vertex small, triangular, lateral carinae large, meeting together at apex. 
Base of frons narrow with lateral carinae touching, gradually widening to 
apex, lateral carinae large, curved under the antennae, but do not form a 
subantennal process. Clypeus shorter than frons, rounded. In profile ver- 
tex and frons forming a curve. Pronotum angularly emarginate posteriorly, 
very short in middle, no shoulder carinae or only a very slight indication 
of any; mesonotum broader than long, without carinae. Antennae shorter 
than frons, first segment wider than long, length of second segment about 
twice the width, apex slightly larger than base. Female genital style small, 
but complete. Hind tibiae with two or three small spines, which are miss- 
ing in some specimens. 
This genus stands between Symedia and Mysidia, but, as it 
has only three Cu veins reaching the hind margin, and the sec- 
tors of M are not incorporated into the Cu, it must be placed 
in the Cenchreini. It differs from Symedia in having no shoulder 
keels, the Cu with three branches instead of two, the basal M 
sector two-branched instead of three, and the second M sector 
two instead of one branch; wings are also proportionately much 
larger. In Dawnaria Dist. the M is not pectinate and in Phenice 
Cu has two branches, the first M sector two, and the others are 
simple. 
Type D. maculata. 
Dysimia maculata sp. nov. Plate XII, Figs. 2, a. 
Male. Length, 1.5 mm.; tegmen, 3.6 mm. 
Stramineous; genae in front of eyes, the middle of mesonotum and 
basal portion of abdominal tergites fuscous, fuscous over lateral portions 
of pronotum, a small dark mark on tegulae sometimes forming a distinct 
spot. Tegmina hyaline, slightly opaque with waxy secretion and very 
slightly fusecous, especially over apical cross-veins and in apical cells, veins 
stramineous with fuscous marks; four black spots on tegmen, the largest 
on Cula, a smaller one at base of Cul, another in costal cell at base of 
Se-+R fork and a very small one on M basad of first sector. Wings hyaline, 
veins stramineous with fuscous markings, a round black spot between Cu 
and A. 
Anal segment small, anus near base, lateral edges curved ventrad. 
Inner margins of genital styles slightly concave on basal half and conyex 
on apical half, outer margin produced angularly in middle, the apex of 
the angle produced into a thin, curved process. 
Female. Length, 1.9 mm.; tegmen, 4 mm. 
In color similar to male, the fuscous on tegmen a little darker, and the
