strongly flattened below near base and conspicuously curved in apical 

 third. 



Terminalia: Genital capsule shining, with scattered obsolete and 

 minute punctures; gonostylus as illustrated (fig. 252). 



Length of body: 10.01(9.16-10.81). 



Female: rather similar to male, but posterior femora with only a 

 weak indication of the subapical tubercle ventrally, tibiae more weakly 

 but still distinctly flattened and curved as described for male. Meas- 

 urements averaging somewhat smaUer. 



Head: Length-width ratio: 1.55(1.52-1.59) :2.47(2.40-2.53); inter- 

 ocular width, 1.48(1.36-1.59). Antennal segments: I, 0.53(0.50-0.56); 

 II, 0.64(0.63-0.66); III, 0.51(0.50-0.53); IV, 0.73(0.70-0.76); V, 

 0.78(0.76-0.80). Labial segments: I, 1.05(0.98-1.10); II, 1.39(1.26- 

 1.50); III, 1.25(1.10-1.33); IV, 0.87(0.76-0.93). 



Pronotum: Width-length ratio, 5.42(5.24-5.58) :2.88(2.70-2.97). 



Scutellum: Longer than wide, 3.64(3.45-3.78) :3.37(3.30-3.45). 



Length of body: 9.88(9.61-10.05). 



Type data. — Dallas' types (BrM) were listed as coming from 

 "Jamaica" and "S. America." 



Specimens studied. — 4 males, 13 females. 



Bahamas: Andros Island, May-June, 1904, W. M. Wheeler, 1 female (AmM); 

 W. M. Mann, 1 female (USNM). Cat Island, Arthur's Town, July- Aug., 1935, 

 W. J. Clench, 2 females (MCZ). South Bimini Island, June 20, 1950, Cazier and 

 Rindge, 2 females (AmM, RCF); July, August 10, 15, and 21, 1951, C. and P. 

 Vaurie, 5 females (AmM). 



Jamaica: South of Bug River, Mar. 30, 1906, A. E. Wright, 1 male (MCZ). 

 Port Antonio, 1 male (MCZ); January, A. E. Wright, 1 male, 1 female (AmM). 

 Richmond, Nov. 2, 1 male (USNM). Stoney Hill, M. Bovell-37, 1 female 

 (USNM). 



Discussion. — Several interesting types of variation were noted in 

 the small series studied. These included a difference in pronotal 

 punctation, in degree of concavity of anterior pronotal margin, and 

 the size of the ocelli. The pronotal punctation on the specimens from 

 the Bahamas was coarser, impressed, and more abundant in the 

 transverse impression (fig. 70) than on those from Jamaica (fig. 71). 

 The Island of Cuba, lying between the Bahamas and Jamaica, was 

 not represented in the material studied. A series from Cuba compared 

 with specimens from the other two localities should prove interesting. 

 The degree of concavity of the anterior margin of the pronotum (figs. 

 70, 71) and the variation in ocellar size showed no such geographic 

 arrangement.
