the 2d abdominal segment also yellowish in the middle and along the 

 basal suture. Wings hyaline, iridescent; the venation is similar to 

 If. ceeopsidis, only the 1st and 2d transverse cubital veins are not par- 

 allel, but convergent, the 2d submarginal cell therefore trapezoidal. 



Habitat. — Cocoanut Grove, Florida. 



Described from a single specimen, reared from the larva of an Arciiid 

 found on Chrysobalanus, and collected by Mr. E. A. Schwarz. 



Meteorus orchesias u. sp. 



Male and female.— Length, 3f to 4£ mm ; ovipositor, 3 to 4 mra . Head, 

 thorax, 1st abdominal segment, and usually the tips of the abdomen, 

 black ; collar, legs, and abdomen, except as mentioned, vary from a 

 honey-yellow to pale yellow ferruginous. The face in the male is ferru- 

 ginous, antennae 34-jointed, long; in female antenna? 24 jointed, shorter. 

 The parapsidal grooves are distinct, converge behind, but do not quite 

 reach to the base of the scutellum ; the middle lobe posteriorly is finely 

 shagreeued; in the male the pleura and scutellum are ferruginous; 

 metathorax coarsely rugose, delicately areolated; the 1st abdominal 

 segment is longitudinally aciculated. Wings hyaline, iridescent; the 

 costa? and stigma brown, the latter having a yellow spot at the base ; 

 veins yellowish ; the 2d branch of the radius is about twice as long as 

 the 1st, the 2d submarginal cell trapezoidal. 



Habitat. — Grand Ledge, Michigan. 



Described from six specimens, three males and three females, labeled 

 No. 2405°, reared July 24, 1881, from Orchesia castanea found in brown 

 woody fungus growing at the above place. 



Meteorns euchromiae u. sp. 



Male and female. — Length, 3§ to 44 mm ; ovipositor, l 1 ""'. Pale yellow- 

 ferruginous; eyes very large, purplish brown; palpi and legs pale; 

 post-petiole dorsally black. The antennae are 25 jointed in female, 31- 

 jointed in the male; parapsidal grooves obliterated, or at least not 

 sharply defined, the middle lobe being more or less shagreeued and the 

 parapsidal grooves only indicated by shagreeued lines; metathorax 

 minutely rugose, the lateral and medial carina* ouly faintly traceable; 

 abdomen normal, the 1st segment or petiole, strongly, longitudinally 

 aciculated. Wiugs hyaline, iridescent; the costre to the parastigma, 

 median and submediau, aud basal veins dark brown or black; other 

 veins, including the stigma, yellowish ; the 2d branch of the radius is only 

 a little longer than the 1st, and shorter than the 2d branch of the cubi- 

 tus; the 1st transverse cubital nervure is oblique aud not interstitial 

 with the recurrent nervure; the 2d submarginal cell is therefore trape- 

 zoidal. 



Habitat. — Caracas, Venezuela. 



Described from several specimens, in both sexes, received September 

 23, 1886, from Dr. A. Ernst, of Caracas, who reared them from Euchro- 

 mia eriphria Fabr.
