extending as far ventrally as in B. anita (Fowler); second valvulae with 
primary teeth broader and fewer than in anita. 
Crown with submarginal pale band as in B. doriona, n. sp. (below), but the 
band with a broad complete posterior margin of black enclosing a small me- 
dian pale yellowish semicircular area on posterior margin; pronotum with 
three longitudinal percurrent pale bands of which median one bears a very 
thin median inconspicuous black line which extends, with the pale line which 
it bisects, almost to apex of scutellum; markings of clavus as in dortona; 
corium with a slender elongate stripe in middle third of length of wing in 
middle of width of corium, a marking in the form of an inverted exclamation 
point (!) along outer margin of inner apical cell, and a transverse slender, 
lobate spot extending from costal margin into base of outer apical cell, yellow 
to orange; otherwise colored as in dortona. 
Holotype male, ‘“‘Waldeck”’, Costa Rica, February 10, 1934 (C. H. Ballou), 
“Costa Rica No. 2435”’; one male and one female, El Valle, Panama, August, 
1948 (N. L. H. Krauss) (USNM). 
Beirneola coripana, n. sp., is similar externally to B. anita (Fowler) from which 
it differs in its narrow median dark line on the pronotum, its more abruptly 
narrowed male plates, its broader style apices, and in the female by its lack of 
a slender elongate acute median process from the posterior margin of ab- 
dominal VII. 
Beirneola doriona, NEW SPECIES 
FicguRE 452, PAGE 553 
Length of male 6.2-6.5 mm. Head with median length of crown varying 
from slightly less than six-tenths to approximately two-thirds interocular 
width, and from slightly less than four-tenths to slightly greater than four- 
tenths transocular width. Male pygofer with posterior margin angular postero- 
dorsally, with many macrosetae of uniform size, without interspersed 
microsetae; plates abruptly narrowed in basal third; style not extending as far 
posteriorly as apex of connective, apex rounded. Female unknown. 
Crown marked with pale submarginal arch of greenish-yellow connected 
with a similarly colored median band of same width, the two lateral extremi- 
ties of the arch and the median band extending posteriorly over pronotum to 
its apex, the median one continuing to scutellar apex, the lateral ones ex- 
tending onto forewings and attaining claval apex, commissural margin of 
basal two-thirds of clavus narrowly yellow; corium with a slender oblique 
mark opposite apical half of clavus and a similarly slender oval mark in apex 
of outer anteapical cell, ivory to pink, with a slender transverse lobate ivory 
spot extending from costal margin into base of outer apical cell, ground color 
of forewings black; face and thoracic pleura black, legs stramineous. 
Holotype and two additional males, Batatal, Bolivar, Colombia, 1938-1939 
(M. Althen-Dahl) (ZIL). One male, Bogota, Colombia (Lindig) (RMS). 
B. doriona, n. sp., may be separated externally from other species of the 
genus by the more extensive pale median coronal marking which is confluent 
with the anterior submarginal pale arch in doriona, whereas the arch is com- 
pletely bordered posteriorly with black in other species where it occurs.
