identity in the restricted sense of Bellardi’s 3 and other per- 
tinent types, and (3) of definite information of what exten- 
sion from the Neotropical fauna has taken place through 
Mexico. In other words, while additional variants in the 
southern United Staates are still evident, any further res- 
triction of Nearctic “lineola” at the present time involves 
the danger of confusing, rather than clarifying the complex, 
except to point out such elements for reference for the future 
reviewer when adequate information is available. Among 
such observed elements divergent from lineola s. str. may be 
mentioned the following. 
Tabomus truquii Bell, has been variously applied to hairy- 
eyed variants found in Texas and the Southwest. The males 
were considered by Stone (1938) and Bequaert (1940b) to 
have areas of greatly enlarged facets, and Bellardi describes 
eyes of both truquii and carneus as “superne minute, inf erne 
minutissime reticulatis” , hairy in the former with dark scu- 
tellum and femora, but bare in carneus with flesh colored 
scutellum and posterior legs (his statement “tibiarum basi 
nigris” is not clear). Schwardti appears closest to truquii 
except for the red scutellum and its unknown occurrence in 
Mexico. On the other hand, since the relative differentiation 
of large and small facets in Bellardi’s description is still 
speculative, truquii might also apply to amylifrons which 
must extend through Mexico. The question of application 
of this name to any Nearctic form will have to await further 
clarification of the Neotropical species, but it cannot apply 
to an immediate variant of lineola s. str. as also recognized 
by others. 
Less divergent is the large, yellowish, evenly lined variant 
seen from Miss., La., and Tex., labelled and figured by Hine 
(1906, 1907) as T. quinquevittatus Wied. The name cannot 
apply as discussed later. The hairs and pollinosity of the 
venters and middorsal stripes are much more intensely yel- 
low than in any other form. The fronts of the females are 
relatively wide, the eye facets of the males are markedly 
differentiated but the hairs reduced; the scutellums and 
femora are dark. While the wide fronts undoubtedly sup- 
port tinctorial separation from typical lineola, the uncertain 
3 No response regarding Bellardi’s types was elicted from the Turin 
Museum on repeated requests in prewar correspondence.
