Drosophila ramsdeni, n. sp. 



9 . Arista with 4 branches above and 2 below. Antennae pale yellow, 

 third joint reddish brown above. Front pale yellow, 3 brown spots 

 on each orbit, and one around each ocellus. Second orbital one-fourth 

 size of other two. Vibrissa three times size of other oral bristles. 

 Carina large, broad, sulcate. Face and cheeks yellow, a brown spot 

 just below carina; and one just below each eye. Eyes with black pile. 



Eight acrostichal rows, no prescutellar bristles. Dorsum of thorax 

 light gray, each hair and bristle arising from a dark brown spot. Between 

 the dorsocentrals these spots are fused into a pair of irregular longi- 

 tudinal stripes. Scutellum light gray, basal pair of bristles arising 

 from brown spot. Pleurae dark brown above, pale yellow below. 

 Legs pale yellow, tips of femora and bases of tibiae brown. Apical 

 and preapical bristles on first two pairs of tibiae, preapicals on third. 



Abdomen yellow; each segment with a dark brown cross band, 

 which is broadly broken in the median dorsal line. 



Wings clear; veins pale brown, with dark brown spots at tip of first 

 section of costa and at junction of first and second veins. Costal 

 index about 2.6, fourth vein index about 2.0, 5x index about 1.2, 4c index 

 about 1.1. 



Length of body 2^mm., wings 2^mm. 



Type and paratypes, from pineapple, sent from Guantanamo, 

 Cuba, by Mr. Chas. T. Ramsden, Dec. 1913. The type itself 

 was bred, from this stock, in New York City, Feb., 1914. 



The males agree with the above description in all respects. 



This species resembles D. repleta Woll., but is easily separated 

 from it on the basis of its banded legs, lighter color, and more 

 slender form. 



D. ramsdeni is the "Species A" of Metz (1914, Journ. 

 Exper. Zool. 17, p. 50). 



Drosophila saltans, n. sp. 



d^ . Arista with 5 branches above and 3 below. Antenna brown, 

 third joint darker. Front over one-third width of head, wider above; 

 reddish brown, triangle and orbits grayish pollinose, with a brown 

 spot above upper orbital bristle. Second orbital one-fifth other two. 

 Second oral bristle nearly as long as first. Carina high and narrow. 

 Face brown, proboscis brownish. Cheeks yellowish brown, their 

 greatest width scarcely one-sixth greatest diameter of eyes. Eyes with 

 short sparse dark pile. 



Acrostichal hairs in six rows; no prescutellars. Dorsum of thorax 

 grayish brown pollinose, with markings of dark dull brown as follows: 

 a pair of short longitudinal stripes on the front margin, just within the 

 dorso-central row of hairs; two pairs of spots just outside the dorso- 

 central row, one just behind the humeri and the other just behind the 

 transverse suture. Scutellum grayish brown pollinose. Pleurae dark
