Female genitalia (see Tjeder, 1971). Seminal bursa small, open- 
ing ventrally directly into the spermatheca; bursal glands slender, 
dorsal. 
This species is recognizable by the heavy wing veins, alternately 
black and white, conspicuous crossveins beneath stigma, and head 
markings. The short ectoprocts, without hinge, are unusual, but 
also occur in S. squamosus (Tjeder) from Africa, S. confraternus 
(Banks) 1913 n. comb. (Chrysopa) , from Argentina, and several 
undescribed species. The type of U. annulata differs slightly from 
that of S. argentinns in having the stigmas opaque pale yellow 
(probably an artifact of preservation) and having an irregular 
longitudinal dark stripe in the dorsal antennal fossa. C. venulosa 
Navas 1918 and C. nervulosa Navas 1924 are probably S. argen- 
tinus; I have not seen the types. 
Material examined — the following are in my collection : R. 
Argentina, Santiago del Estero: Choya, Oct.-Nov. 1961, 13 females, 
3 males; Fernandez, Feb. 1957, 11 females, 2 males; El Pinto, 
Dec. 1956, 2 females. La Rioja: Patquia, 600m., Dec. 1 957 > 1 
female, 2 males. 
Genus Mallada Navas 1925:24 
Mallada basalis is conspicuously dimorphic sexually, the males 
having heavy elongate stigmas, and Sc and Rs fused in the hindwing. 
These features were noted by Navas, who based his genus Mallada 
upon the thickening of the stigmas. The type species of Mallada, by 
original designation, M. stigmatus , is a synonym of M. basalis. The 
type species of Anisochrysa , A. paradoxa, was also synonymized with 
M. basalis by Adams (1959: 25). Anisochrysa is therefore a junior 
objective synonym of Mallada. 
Most species of Mallada can tentatively be assigned by venational 
characters. The inner gradate series in larger species with numerous 
veins extends basad parallel to psm, hence does not converge on psm, 
and the basal inner gradate crossvein does not end on psm, but on a 
branch of Rs, resulting in a. y-formation. A similar configuration, as 
shown in Fig. iA, forewing, occurs also in other genera such as 
Suarius, but is rare in Chrysoperla and Chrysopa, s. str. Psm in 
Mallada only very infrequently includes a crossvein (the only ex- 
ample of which I am aware is M. venosellus (Tjeder 1966, Fig. 
1643), but commonly includes 1 to 3 crossveins in Suarius. 
Mallada, named after the Spanish naturalist, D. Lucas Mallada, 
is masculine, necessitating changes in many terminations. It con-
