as the arista, three posteriorly confluent stripes on the meso- 
notum, the pleurae and the basal portion of the first 
(second?) abdominal segment, black. This segment has a 
yellow spot on each side. The hind femora, except their 
tips, the median portion of the hind tibiae and the tip of 
the second joint of the hind tarsal are also black. The 
fourth posterior and anterior anal cell are closed as in 
tibialis, but the hind tibiae have two spurs as in V. vermileo. 
The markings on the wings resemble those of the Jamaica 
tibialis in being brown, but the extreme tips seem to be pale. 
Williston’s specimens were males measuring 10-12 mm., and 
were therefore as large as females of the var. dowi.
