18 Psyche [March- June 
722) established what appears to be the correct synonymy of 
this species. It is known at present from Mexico, Guatemala, 
Honduras, Panama, Colombia, Trinidad and northern Brazil. 
At one time I referred the Trinidad specimens to Tab anus 
luteoflavus Bellardi (see J. Beqaert, 1940, Rev. de Entomolo- 
gia, 11, p. 272) ; but this was erroneous. As for the green male 
from Paraguay which I mentioned at the close of the discussion 
of T. viridis , it has now been recognized as that of Tabanus 
( Cryptotylus ) princeps Brethes. 
19. Tabanus (Leucotabanus) leucaspis Wiedemann. 
Princes Town, female (R. C. Shannon); Saut d’Eau Bay, 
female, biting man (E. McC. Callan) ; St. Augustine, 2 females 
(Ruth O’Connor); Tacarigua, several females (T. H. Khan); 
Tamano,. female (A. M. Adamson) ; Maracas Valley, female 
(M. V. Beattie). Other females merely labeled Trinidad (Stan- 
ton Crawford). 
A common species in Trinidad. I have also seen one female 
from Speyside, Tobago (biting man) (E. McC. Callan). 
20. Tabanus (Macrocormus) sorbillans Wiedemann. 
St. Augustine, 4 females (A. M. Adamson; E. McC. Callan) 
and 2 males (Ruth O’Connor); Tamano, female (R. C. Shan- 
non). 
According to a sketch by Dr. Shannon, the eye of the female 
is purple with 2 rather narrow green cross-bands in life. 
21. Tabanus (Stenotabanus) maculifrons Hine. 
Blanchisseuse, female (R. C. Shannon). 
This remarkable little horsefly was originally described from 
Guatemala (1907, Ohio Naturalist, 8, p. 222 ; 9 ). I have taken 
a female in Colombia (Caney River near Restrepo, Int. Meta) 
and G. B. Fairchild found it in Panama. The eye, which I ob- 
served in life and which was also sketched by Dr. Shannon, is 
pale purplish with two moderately broad, unconnected bluish- 
green cross-bands: one shorter, starting from the frontal callus; 
the other in the lower third, curved upward at the outer end. 
22. Tabanus (Neotabanus) hookeri Knab. 
St. Augustine, several females (D. J. Billes; E. McC. Callan; 
D. K. Kevan) ; also one female as prey of Rubrica surinamensis 
(Degeer) and one male as prey of Stictia signata (Linnaeus) 
(E. McC. Callan) ; El Dorado Village, female (M. V. Beattie).
