under lineola, but Fairchild has indicated the evident re- 
lationship of this and nippontucki below with Neotropical 
variants of which vittiger Thomsen appears to be the prior 
name, although no males yet are available from the 
Galapagos Islands. 
This is the form chiefly reared by Schwardt (1931), and 
at once distinguished from scutellaris males by the large 
head with much enlarged upper eye facets occupying fully 
three quarters of the total eye area, and with more pro- 
nounced hairs. Furthermore, the palpi are often less blunt 
and abdominal pattern more contrasting like the females; 
the fore femora and to a less extent the hind and mid pairs 
are infuscated. Except for such infuscation of the femora, 
the females closely resemble those of scutellaris. For this 
reason, the male which is the most distinctive sex is used as 
type. 
Holotype S , 12.5 mm. Area of enlarged facets chocolate 
brown (yellow in some paratypes), flattened across disc, 
hairs distinct, and more dense than in typical lineola, ver- 
tical tubercle small, even with upper eye level, brownish 
pilose. Face white, palpi creamy with white and occasional 
black hairs, blunt apically (pointed in many paratypes). 
Antenna red, annuli black, first segment not unusually swol- 
len, plate obtuse angulate and very moderately excavated. 
Thorax quite hirsute, including some pale purplish, appres- 
sed hairs dorsally and the usual, rather indistinct lines ; pos- 
terior half of the scutellum reddish. Wings hyaline, no 
stump. Fore femora, basal two thirds of hind, one fourth 
of mid-femora, and distal half of fore tibiae and tarsi ciner- 
ous to blackish. Abdominal stripes distinct and contrast- 
ing, the median even and white, the sub-lateral irregular 
and yellow, the 4 intervals dark brown rather than black. 
Venter yellowish with dusky spots in the middle of the first 
2 sternites and edges of all ; black hairs only on last two. 
Allotype $ , 13 mm. In essential agreement with the 
holotype except for the usual sexual characters. Eyes ex- 
tended laterally and the characteristic eye pattern (relaxed) 
usual for the group, front subparallel in upper third, con- 
vergent below, index 1 : 4.8, the basal callosity very deep 
brown, quadrangular, a little taller than wide, the median 
callus small and hardly connected. The antennal plate nar-
