BLEPHARONEURA.—EUTRETA. A415 
3. Blepharoneura quadristriata, sp.n.¢. (Tab. XII. fig. 7, wing.) 
Rufous; thoracic dorsum with four black stripes; abdomen with black, medially interrupted, cross-bands ; 
wings fuscous, with hyaline spots. 
Length 4 millim. 
Like the preceding (B. femoralis), but smaller, and without black spots on the pleure; the hind femora not 
black at the tip; the black lateral stripes of the abdomen broader and leaving only a rufous dorsal band, 
without spots. The fuscous coloration of the wings is more extended, the hyaline spots beyond the stigma 
and the spot on the hind margin being smaller, this latter is subtrigonal, with a fuscous stripe in the 
middle; the hyaline spots in the apical part of the wings are less numerous and more separated une 
from another. 
Hab. Mexico, Teapa in Tabasco (H. H Smith). 
A single male specimen, with the antenne broken off. 
4, Blepharoneura biseriata, sp.n.,2. (Tab. XII. fig. 8, wing.) 
Rufous; the stripes on the thorax, the base of the scutellum, and the cross-bands on the abdomen, brown; 
wings fuscous, with hyaline spots, which at the apex are arranged in two rows. 
Length 4 millim. 
This species also is closely allied to B. femoralis, and agrees with B. quadristriata in the smaller size and the 
absence of black at the tips of the hind femora. The dark markings of the thorax and abdomen are 
brown (perhaps due to the immaturity of the specimen); the pleure have some brownish spots. The 
ovipositor is shining brown, flattened, broad, truncated at its end. The pattern of the wings, though in 
general agreeing with that of the preceding species, differs in the apical region, where there are an inner 
row of five and an outer row of three hyaline spots. 
Hab. Mexico, Sierra de las Aguas Escondidas in Guerrero 7000 feet (H. H. Smith). 
A single female specimen.
