While examining some tabanids in the Canadian National Collec- 
tion at Ottawa, I came upon a representative of a second species of 
the genus Querbertia Fairchild, previously known by only the type- 
species, bequaerti (Fairchild, 1964). This new species, also from 
Peru, is as follows: 
Querbetia inopinatus n.sp. 
(Fig. 1) 
Female. Length 13.5 mm., of wing 10.5 mm. Resembles Q. be- 
quaerti closely in structure, but differs in the following respects. 
Frons slightly wider than in bequaerti , the bare areas dark brown, 
the pollinose areas golden yellow rather than black and grey. Sub- 
callus and basal antennal segments as in bequaerti, but dark brown, 
die sutures and inner bases of scapes yellowish. Third antennal seg* 
ment as figured, as long as frons and first two segments of antennae, 
or about equal to mid tibia, the basal plate yellowish brown, the style 
black, subshiny. Frontoclypeus and genae as in bequaerti, but the bare 
areas yellowish to brown, the pollinose areas yellow. Palpi yellowish 
brown, shiny, pale-haired, more slender than in bequaerti. Proboscis 
brown, the sclerotized strip on labella narrower than in bequaerti . 
Mesonotum subshiny, blackish brown, with a pair of dorsolateral 
golden-haired stripes, and sides including notopleural lobes golden- 
haired. Scutellum dark brown in ground color, but densely golden 
pollinose and golden-haired. Pleura blackish, but with pronotal lobes 
and mesopleura extensively dull yellowish pollinose. Coxae blackish 
brown, femora dark yellow, tibiae light yellow, the basal halves or 
less white and white-haired, tarsi yellow, all clothed with yellow 
hairs except bases of tibiae. Wings with venation as in bequaerti, but 
the whole wing yellowish, more intense in costal cell and anterior 
half. 
Abdomen slender, rather long, subshiny, dark brown. First seg- 
ment almost divided by a broad posterior median sulcus, dark-haired 
except for a narrow fringe of dark yellow hairs. Second segment
