little nearer the tip of the wing, as the wing seems somewhat 



shorter. (This character is of little value in separating the species, 



as the difference is so slight that il would not be noticed without 



comparing the two). The male hypopygium is rather large and 



somewhat bent froward, projecting nearly half its length below 

 the venter of the abdomen. 



I have received from Prof. J. M. Aldrich a male which e\idently 

 represents another s|X'cies. I do not think it can be the same as 

 the males Wheeler had. The following is a description of this 

 species: — 



Chrysotimus flavicornis, n. sp. 



Male — Length l.Tomni. Faceand fronlgreen with whitcpollcn, 

 which does not conceal the ground colour; ocellar tubercle blackish; 

 palpi brown; antennic >'ellow (third joint missing in the type). 

 Thorax pale green with I^right coppery reflections and thickly 

 covered with grayish white pollen; prescutellar depression sharply 

 defined; pleuric black with grayish pollen. Abdomen green with 

 slightly coppery reflections and dulled with gray pollen; hairs and 

 bristles of the thorax and abdomen yellow; hypopygium short, 

 yellowish brown with a black appendage covered with rather long 

 black hairs at the centre of the posterior side; venter yellow. Coxa? 

 and legs yellow. Teguhe, their cilia and the halteres >ellow. Wings 

 tinged with yellow; costa and veins yellow; third and fourth veins 

 parallel beyond the cross-vein; apex of wing equidistant from the 

 tips of the third and fourth veins; posterior cross-vein a little 

 beyond the middle of the fifth vein. 



Described from one male taken at Richmond Hill, L. I., \. Y., 

 July 5th, by Mr Daecke. Type in the collection of Prof. J. M. 

 Aldrich. 



The yellow antennas and thick pollen of the thorax and abdo- 

 men separate this form the two preceding species. It differs from 

 Prof. W'heeler's description of the supposed male of C. piisio Loew 

 in lacking the vi\id green of the thorax and pleura?, the green of the 

 dorsum of the thorax in this species being pale and scarcely shining,, 

 and the pleura? being black.
