!944] Further Studies of the Tabanidce 17 
as prey of the bembecid wasp, Rubrica surinamensis (Degeer), 
El Dorado Village, female (M. V. Beattie; named T. ferrifer 
by the late Major E. E. Austen) ; Nariva Swamp, female (R. C. 
Shannon); Mundo Nuevo, female (R. C. Shannon); Tamano, 
female (R. C. Shannon) ; Siparia, female (R. C. Shannon). 
According to Dr. McC. Callan, this is one of the commonest 
horseflies at St. Augustine, the males being found in ones and 
twos sitting in sunny places from about 8 a.m. to 4 p.m. 
14. Tabanus (Bellardia) xipe Krober. 
St. Augustine, male, October 22, 1937 (A. M. Adamson); 
Tamano, female (R. C. Shannon). 
Male (undescribed). — Differs from the male of T. ferrifer 
in size, extent of the velvety-black spot of the scutellum, mark- 
ings of abdomen, color of wings, presence of a long appendix 
at the fork of the third longitudinal vein, and shape of antennse 
In all these characters it agrees with the female of xipe. The 
eyes are entirely bare and divided into an upper zone of en- 
larged and a lower zone of small facets. 
Dr. Shannon sketched the eye of the female as purple with 
three green cross-bands, the upper one rather broad but short, 
the lower one very broad and somewhat narrowed outwardly, 
the middle one much narrower than the others and somewhat 
wavy. 
According to G. B. Fairchild (1942, Psyche, 49, p. 8) Lopho- 
tabanus Szilady (1926) is not subgenerically separable from 
Bellardia Rondani (1863), an opinion with which I concur. 
15. Tabanus (Phaeotabanus) semiflavus Krober. 
Princes Town, female (R. C. Shannon). 
This specimen agrees with two females I have seen from 
Brazil (Curralinho, State of Para). The species was first de- 
scribed from Venezuela. 
16. Tabanus (Chlorotabanus) mexicanus Linnaeus. 
Tamano, female (R. C. Shannon). 
17. Tabanus (Cryptotylus) unicolor Wiedemann. 
Mayaro, female (D. K. Kevan) ; Tamano, 2 females (R. C. 
Shannon). 
18. Tabanus (Cryptotylus) limonus Townsend (= Ommallia 
viridis Enderlein).
