Paratypes, 2 females same locality as holotype, labelled 
15-V-35 and 21-V-35; 4 females Panajachel, Guatemala, 6 
Aug. 1943, and 1 female Tzanjuyu, Panajachel, Guatemala, 
20 Aug. 1943, D. M. Jobbins coll.; 3 females Antigua,

The holotype and the two other Chiapas specimens are 
from the late Dr. A. Dampf’s collection, labelled in his 
handwriting, and sent to me by Dr. C. B. Philip. The 
holotype and seven paratypes are in Dr. Philip’s collec- 
tion, the remaining paratypes in the author’s collection. 
This obscurely marked little species was tentatively de- 
termined by both Dr. Philip and myself as St. pallipes 
Krober, described from Brazil. Krober’s description was 
drawn from a specimen preserved in alcohol, but indicates 
a much paler, more yellowish insect, and the wings are 
described as absolutely glass clear. Three of the present 
series were also alcoholics, but are very much darker than 
Krober’s description indicates. The present species also 
shows differences in the frons and a somewhat broader 
third antennal segment and more slender palpi. 
From the description of Tabanus siibtilis Bell the present 
species differs in having wholly pale antennae and pale 
femora. Dr. Bequaert’s notes on the types show that sub- 
tilbs is a Stenotabanus, with bare subepaulets, and he con- 
firms the presence of a black annulate portion to the third 
antennal segment. 
Tabanus pumiloides Will, differs, according to the de- 
scription, in having a much more marked angle on the 
dorsal aspect of the third antennal segment, and also in 
having a black annulate portion to this segment. The legs 
are said to be black with the tibiae basally yellow. It seems
