98. Euxesla notata Wicd. 



Uray, Colo. An adult of this trypetid was reared, October 30, 

 by Prof. F. M. Webster, from a j)laiit of O.njtropl-i /«)/(6e/'f/ collected 

 at Uray, Septend)er •"). 



99. Louclisea orchideHi'iiiii n. sp. 



Length 1.5 mm. — Eyes dark brown, with a greenish tinge, probably greenish in 

 life ; front and face blackish, the former wit'h several bristles near vertex. An- 

 tennae black, very short, third joint rounded, arista short and comparatively 

 rather stout. Thorax shining metallic black, with a hardly greenish tinge; scu- 

 tellum with more of a greenish tinge. Abdomen deep metallic green, rather 

 short and somewhat pointed apically. Legs blackish. Wings much longer than 

 abdomen, clear hyaline, iridescent in oblique lights. 



Kingston, Jamaica. One specimen bred, March 19, from a flower 

 stem of an orchid {OticuUinn lurid ton) brought from Kingston 

 Gardens, February 22. 



The specimen agrees well with Schiner's characterization of Lon- 

 cJupa. The habit also agrees, as the larva of the European L. nigra 

 Meig. has been found in the stems of Verbascum, Angelica and 

 Carduu.% while other species have a similar habit. The present spe- 

 cies belongs to none of the three described by Wiedemann from the 

 neotropical region, viz., L. glaherriina W. I. ), chnlybea 'Brazil), 

 and nigra (Brazil), and, while in this connection, the name nigra 

 Wied. (1M80) is preoccupied by the European L. nigra Meigen ( 1826), 

 Wiedemann's species may, therefore, be known as L. loledemarmi. 

 Type in coll. Townsend. 



100. Drosophila sp. 



Vera Cruz, ^lexico (Cockerell) ; bred in box of Pulrlnaria and 

 Orthezia from Vera Cruz, Mex. Probably issued from Pitlvinarin 

 Ivtea Ckll., a beautiful yellow coccid. Length about 2.5 mm. Eyes 

 bright scarlet in life. Body of a general pale yellowish color. This 

 is quite possibly D. mexicana Mcq. 



101. Lieucopis bella H. Lw. 



I identify a specimen from Colorado, bred by Prof. Gillette from 

 plant-lice, as this species. It agrees very well with Loew's descrip- 

 tion, except that the second abdominal segment has two black spots 

 and no small dot between them, or scarcely a faint trace of one. 

 The antennte are but little silvery. It must, however, be considered 

 the same species. I sliould judge' that Dr. Williston's L. beUula 

 ( " Insect Life," i, 258) is a very distinct species. L. bella, as de- 

 scribed by Loew, has a median basal dot and two larger dots on the 

 second abdominal segment, and a median dot on the third and fourth 

 segments, while L. bellula has a pair of dots divided by a median 

 line on each segment except the first.
