20 THE FLORIDA ENTOMOLOGIST 
Genitalia: Female, last ventral segment scarcely longer than penulti- 
mate; posterior border sinuous, the middle third and lateral lobes produced; 
minutely notched on middlle, lateral lobes rounded. 
Described from two spemines, females, (type and paratype) collected 
at Gainesville, Fla., by C. J. Drake. Type in Osborn collection, Ohio State 
University. 
This species is very close to magnus O. & B. but aside from the con- 
spicuous transverse spots on the elytra, the costa is not white and the 
female segment differs in form. 
Euscelis (Athysanus) magnus var piceus, n. var. 
Similar to magnus of typical form but with the coloration, except for 
the white band on the pronotum and the costal border, of a deep pitchy black 
and the female sgment with median notch much smaller. Collected by Mr. 
H. L. Dozier at Pascagoula, Miss., Aug. 8, 1921. 
Mesamia nervosus, n. sp. 
Light yellow; vertex with an interrupted submarginal black border; 
elytra with fuscous veins; five or more conspicuous’ cross veinlets in the 
outer costal area. Length, female 4 mm.; male 3.5 mm. 
Head slightly wider than pronotum; vertex nearly twice as wide as long, 
rounded in front, about one-fourth longer at middle than next the eye, 
distinctly angular to front; front narrowing nearly uniformly to base of 
clypeus; clypeus narrow, nearly twice as wide as long, slightly widened to- 
ward the tip; lorae rather narrow, with tip nearly reaching to the margin 
of the cheek; cheek slightly sinuate below the eye. Pronotum two-thirds 
longer than vertex, slightly concave behind; elytra with cross veinlets in 
outer claval and costal cells; two cross veins. 
Color: Vertex, pronotum and scutellum yellow tinged with green, vertex 
with a conspicuous submarginal band interrupted at the middle behind 
which is a fainter fuscous band in the female, scarcely apparent in the male; 
dise of pronotum darker; elytra hyaline, the veins conspicuously dark fus- 
cous or black, the cross veinlets of costa widening on the margin; api- 
cal broadly blackish; beneath, face yellowish-green, a narrow black line 
bordering the base of front; abdomen greenish, the segments above with 
black spots or bands. 
Genitalia: Female, last ventral segment about twice as long as pre- 
ceding; apex broadly rounded with a faint notch at middle; male, valve 
short, rounded behind; plates triangular with acute upturned tips; the disc 
marked with a distinct impression paralleling the outer border. 
Described from a female, (type) Sept. 27, 1921; and male, (allotype) 
Sept. 9, 1921, collected by Mr. F. E. Guyton, Auburn, Alabama. 
Also one female, (paratype), from Keatchie, La., June 14, 1905. This 
latter differs from the type in having a less distinct second band on the 
vertex, a more distinct yellow color to the pronotum, but otherwise is so 
similar that it seems impossible to consider it a distinct species. 
These specimens approach most nearly to Mesamia stramineus, Osb., 
but have a different shaped vertex and much more distinct venation.
