Handlirsch's specimens and likewise Cresson's came from Cuba, 

 while Dahlbom's were from the Islands of St. Thomas and St. 

 Bartholomew. I have also before me a male and female of this 

 species taken by C. C. Gowdey on the island of Jamaica.

The male of this species, although resembling the male of hidentatd 

 in general appearance, is well marked and distinct. The seventh 

 tergite lacks the lateral spines found on hklentata and is broadly and 

 bluntly rounded. The seventh segment of the flagellum is strongly 

 and transversely excavated below, and segments 9-12 are also ex- 

 cavated but not transversely. The clypeus is strongly prominent and 

 flattened on the ventral part, forming a V-shaped ventral area. The 

 anterior metatarsus bears seven spines and a prominent medina 

 carina below. The posterior border of the middle femur is flattened, 

 somewhat curved, and distinctly dentate. The spur on the middle 

 tibia is dilated, spoon-shaped. The second sternite is tuberculate, 

 the sixth plain, and the seventh bears a prominent, blunt tubercle 

 whose ventral border is flattened. 



The female is characterized by the many spinelike hairs on the 

 sixth tergite. These are also present on the apical border of the 

 fifth. The clypeus bears a median black spot. The fasciae on the 

 tergites are continuous and the sixth tergite has the apical half 

 maculated. 



I have at hand two males and two females of this species deter- 

 mined by Mercet. The four specimens bear a common label, " Los 

 Molinos [Spain] G. Mercet." The species seems to be limited in 

 distribution to those regions bordering on the western part of the 

 Mediterranean Sea.

In this species the ocelli, though much distorted, are not com- 

 pletely obliterated ; lenses are visible. The male, in common with the 

 male of U-scripta Fox, has the scape much thickened, the labrum 

 with a small hump on the midline, the anterior metatarsus with 10 

 spines, the middle tibia with the anterior apical border produced into 

 a spinelike process, the middle metatarsus concave and beset with 

 spines on the inner side, and the seventh tergite with apical lateral 

 ridges and with distinct but not sharply defined basal lateral angles.
