 Plate 5, fig. 12. 

 Lobioptera lacLelpennis Loew, Dipt. Amer. Sept. Ind. Cent., 6, species 97. 

 This appears to be a fairly common species, and is very widely dis- 

 tributed. It was originally described from Cuba ; there are specimens 

 in collection from Biscayne Bay, Florida (Mrs. A. T. Slosson); Dis- 

 trict of Columbia (collection Coquillett); Holly Springs, Mississippi 

 (F. W. Mally); Texas (Belfrage); Mesilla, New Mexico (T. D. A. 

 Cockerell) ; Selma, Alabama, one female taken among aphides on 

 cotton, October (W. H. Patten); Santa Clara County, California 

 (Baker); Brownsville, Texas (C. H. T. Townsend); Dallas, Texas 

 (C. R. Jones); Piano, Texas (E. S. Tucker); Victoria, Texas (W. E. 

 Hinds) ; Whittier, California (P. H. Tunberlake) ; Boerne, Texas (F. C. 

 Pratt) ; Waco, Texas (Belfrage) ; Bayamon, Porto Rico, January, 1899 

 (A. Busck) ; and Santo Dommgo, West Indies (A. Busck). There are 

 also specimens in collection Ceara, Brazil (F. D. da Rocha); the 

 island of Guam (D. T. Fulloway); and several specimens taken in

Genus MILICHIA Meigen. 



M&Ma Meiqen, Syst. Beschr., vol. 6, 1830, p. 131. 

 Lobioptera Wahlberg, Kgl. Vetensk, Akad. Forh., 1847, p. 259. 



This genus may be distinguished by the posterior margin of the eye 

 having no triangular excision, and the mesopleura being bare. The 

 proboscis is not geniculated, though rather over the normal size, and, 

 except at apex, chitinized. 



The species described herewith is the only American representative 

 of the genus which I have seen, and, with this exception, nothing is 

 known of their larval habits. 



MILICHIA AETHIOPS, new species. 



Male. — Entirely black, only the halteres brownish. 



Frons glossy black, sides divergent posteriorly, at upper margin 

 distinctly short of one-third the width of head, at lower margin 

 slightly over one-half as wide as at upper ; surface with longitudinal 

 furrows; orbits very narrow; three orbital bristles present, and a 

 few scattered additional short orbital hairs ; the two rows of setulae on 

 center stripe distinct; antennas black, of normal size, third joint 

 rounded, its surface covered with very short, pale, pUosity; arista 

 with basal joints distinct, and swollen; cheeks linear, marginal 

 bristles strong and closely placed, the vibrissas differentiated slightly 

 and incurved; proboscis yellow at apex; palpi black. Mesonotum 

 glossy; two pairs of doi-so-centrals present, the anterior pair weak; 

 the pair of bristles between the posterior pair distinct ; squama^ white,
