Lonchaea angustitarsis, sp.*n. 



Female. — Black, glossy, with very faint bluish reflections. Frons shining, 

 upper orbits and occllar triangle glossy; antenna^ black. I.egs entirely black. 

 Wings clear. Calyptrai brown, fringes fuscous. Halteres black. 



Frons a little less than one-third of the head-width, microscopically granu- 

 lose, with sparse hairs on the interfrontalia; orbital bristle proximad of the 

 anterior ocellus; lunule with some hairs; third antennal segment about 2.5 as 

 long as broad; cheek with moderately long, sparse setulose hairs; palpi not much 

 broadened. Thoracic bristles much longer and stronger than the hairs; some 

 hairs on margin of scutellum between the bristles; stigmatal bristle simple. 

 Legs slender, the tarsi much more so than in allied species; hind femora without 

 antero-ventral preapical bristle. \^eins 3 and 4 parallel apically. 



Length 3 mm. 



Type.— Echo Lake, Mt. Desert Me.. July 12, 1918, (C. W. Johnson). 

 Type in collection of Boston Society of Natural History. 



Lonchaea nigrociliata, sp. n. 



Female. — Differs from the preceding species in having the tarsi yellowish 

 testaceous, with the apical one or two segments fuscous, and the wings yellowish. 



Frons slightly broader than in angustithrsis, subopaque, and with more 

 numerous interfrontal hairs; frontal lunule bare; third antennal segment broad, 

 its length about twice as great as its breadth; cheek as in preceding species. 

 Legs stouter than in that species, the hind tarsi slightly thickened; hind femur 

 without preapical antero-ventral bristle. Second costal division much shorter 

 than in angustitarsis, the inner cross-vein but little beyond apex of auxiliary 

 whereas in the other species it is almost below apex of first vein. 



Length 3.5 mm. 



Type.— South West Harbour., Me., July 11, 1918, (C. W. Johnson). 



Lonchaea aberrans, sp. n. 



Male and Female. — Similar in colour to nigrociliata. 



Frons of male with two series of long hairs on centre oi interfrontalia. of 

 female with a few hairs in addition to the two series; frontal lunule bare; third 

 antennal segment but little longer than broad, about L5 at most; cheek as in 

 nigrociliata. Upper part of orbits microscopically diagonally striate, with a 

 silky appearance which is quite different from the broader glossy orbits of 

 nigrociliata. Thorax as in that species but usually there are no hairs between 

 the apical scutellar bristles. Legs as in nigrociliaia^ Second costal division 

 shorter than in that species, the inner cross-vein almost below apex of first. 

 Ovipositor very slender, the apical hairs very short. 



Length 3-3.5 mm. 



Type.— Female, Parker, 111., April 17, 1914, (Hart and Malloch). Allo- 

 type, Algonquin, 111., May 4, 1895, (Nason). Paratypes, male, Carlinville, 

 111., determined as polita Say by Williston, (C. Robertson); female. Spruce 

 Brook, Newfoundland. August 8-12 (Amer. Mus. Nat. Hist.); one male and 

 one female, reared from heads of bull thistle, Elphinstone, Man., 

 collected July 27, 1906, emerged in laboratory February 25, 1907, (W. A. 

 Burman). Type in collection of Illinois State Natural History Survey. 



This and the preceding species belong to the subgenus Earomyia.
