Figure 1. Eucaenus ovalis. Drawing of fore wing, based mainly on the Greene 
specimen, G75, and the Sherman specimen, W57, with details from other speci- 
mens mentioned in the text. The veins indicated by broken lines are not clearly 
discernible in any specimen. SC, subcosta (-); Rl, first radius (+); RS, radial sec- 
tor (-); M, media (±); CUA, anterior cubitus (+); CUP, posterior cubitus (-). 
are indicated in some specimens; RS with 6-8 (possibly more) 
pectinately arranged branches, arising at irregular intervals, the 
first one at about 1/3 of wing length, some of them bifurcating 
once or twice; M well developed, not so extensive as RS, forking 
at about the level of origin of RS into two main branches, each 
with 4 or 5 terminal branches arising by secondary and usually 
tertiary dichotomous branching; CU a strong vein basally, di- 
viding below the origin of RS into CUA and CUP, the former 
weakly convex, with little or no branching, the latter strongly 
concave; anal veins weak and irregular. Cross veins numerous 
but weak, not aligned across veins. 
Hind wing; only the basal part along the front margin and the 
apical area are known; costal area narrow, distal part of RS di- 
chotomously branched. 
Body structure (figure 2); total body length ranges from 29- 
32 mm. Head about 3.8 mm long, maximum width (across eyes) 
2.5 mm; mandibles dentate; antennae about 10 mm long, the 
first 3 segments a little broader than the others, which are about 
0.2 mm wide and a little more than 0.5 mm long; total number 
of segments about 20. Maxillary palpi 7 mm long, apparently 
consisting of 4 segments; the basal segment very short (about 
.7 mm), the 2nd and 3rd segments about 2.5 mm long, and the
