1916] North American DrosophilidcB 329 



brown, grayish at the sutures. Legs pale brown, femora and tibiae 

 darker in the middle. Apical and preapical bristles on first and second 

 tibiffi, preapicals on third. 



Abdomen dark brown, each segment grayish pollinose anteriorly. 



Wings with a small blackish speck at tip of first vein. Costal index 

 about 2.0; 4th vein index about 2.6; 5x index about 1.7; 4c index about 

 1.4. Length of body 13^mm., wings l%mm. 



Type and ten paratypes, from stock bred in New York 

 City, from a pineapple sent from Guantanamo, Cuba, by Mr. 

 Chas. T. Ramsden. Four specimens from Panama, R. P., 

 differ only in that the dorsum of the thorax is lighter, and may 

 be referred to this species. 



The name saltans is given because the larvae (like those of 

 D. cardini, n. sp.), have the habit of "skipping" as do those 

 of Piophila casei Linn, and by the same mechanism. 



The species may be recognized by its thoracic pattern, small 

 size and 6 acrostichal rows. 



Drosophila earlei, n. sp. 



cf. Arista with five branches above and two below. Antennae 

 brown, third joint dark. Front over one-third width of head, wider 

 above; opaque reddish brown, orbits and triangle grayish pollinose. 

 Second orbital one-third other two. Second oral bristle nearly as long 

 as first. Carina high and narrow; face brown. Cheeks yellowish 

 brown; their greatest width about one-sixth greatest diameter of eyes. 



Acrostichal hairs somewhat irregular, in six to eight rows; no 

 prescutellars. Dorsum of thorax coffee brown, with yellow-brown 

 markings as follows: a narrow median longitudinal streak, a pair of 

 stripes including the dorsocentrals and broader anteriorly with external 

 branches behind, a spot on each humerus. Scutellimi coffee brown, 

 with yellowish lateral edges. Pleurae coffee-brown; legs pale brown. 

 First and second tibiae with apical and preapical bristles, third with 

 preapicals. 



Abdomen black, four basal segments, each with an interrupted 

 yellowish anterior band. 



Wings clear, veins brown. Costal index about 2.0; 4th vein index 

 about 1.7; 5x index about 1.3; 4c index about 0.9. 



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



Type and two paratypes, Herradura, Cuba, January 28, 

 1915 (C. W. Metz). Other specimens are before me from 

 Cristo, Cuba, and Panama, R. P. The females agree with the 

 description given above. This species is named after Prof. 

 F. S. Earle, on whose plantation the type material was collected. 



This species will be most easily confused with D. saltans 

 n. sp. It dififers in its larger size, yellow markings on abdomen, 

 thoracic pattern, and smaller 4th vein index.
