detached, but visible on sides below ; the second to sixth segments 

 visible above, and a seventh wedged between the sides of ventral 

 aspect of sixth, rounded in outline and forming the base of the 

 hypopygium. This seventh segment occupies the position of a ven- 

 tral plate to sixth segment and belongs to dorsum, being a dorsal 

 plate. Five ventral plates, corresponding to first to fifth segments ; 

 first plate rather crescent shaped, much shorter (antero-posteriorly ) 

 and wider than second to fourth ; second plate long-oval, third and 

 fourth long-elliptical ; fifth subquadrate and widened behind, about 

 as wide as first. Immediately behind the fifth plate is the hypo- 

 pygium, and behind latter is the seventh segment, with the lateral 

 ends of sixth dorsal plate enclosing it on the sides. 



In the female of G. lanipes there are seven ventral plates visible, 

 the first three free, with ventral membrane showing on each side, 

 fourth plate showing ventral membrane only around anterior edge 

 and corners, fourth and fifth plates overlapped on sides by lateral 

 edges of corresponding dorsal plates, sixth and seventh plates over- 

 lapping the corresponding dorsal plates, but sixth overlapped basally 

 by fifth, and seventh by sixth, as is to a less extent fifth by fourth. 

 Seven segments visible on sides and below, the first shortened, the 

 sixth and seventh retracted with only their narrow posterior edges 

 showing, the sixth being retracted within fifth and seventh within 

 sixth. The seventh segment does not show at all dorsally, though 

 the sixth shows equally widely dorsally and ventrally. and sixth and 

 seventh show equally widely ventrally. 



Galactomyia lanipes J. C. Fabricius. — As the description of lanipes 

 is earlier than that of formosa, the species must be known by the 

 former name. Mr. C. W. Johnson, of the Boston Society of Nat- 

 ural History, has a pair of this species taken in copula by Mr. P. 

 Laurent, at Miami, Florida, March 26, 1901. This pair is men- 

 tioned in But. News, November, 1901, page 294. The capture of 

 these specimens in copula confirms Brauer and von Bergenstamm's 

 statement as to the sexes of this species. Both specimens have the 

 palpi black, and the femora wholly black. The male has the abdo- 

 men obscure rufous, the female wholly black. The hind femora are 

 conspicuously flattened-ciliate distally in the male, but only short- 

 bristly-ciliate in the female. Apical cell closed practically in margin, 

 tegulae blackish. The female is the form described by Fabricius and 

 Wiedemann as lanipes. The male is the form described by Wiede- 

 mann as formosa.
