unarmed and proxenus, described from a male, has black legs; dexius, 

 a male, has red legs; eracon has black legs; nyssa has a red abdomen 

 and the legs partly black; indignator has the legs partly black; H. 

 hicolor Ashmead has the abdomen entirely red. 



CHALCIS COMPSILURiE, new species. 



Female. — Length about 4.25 mm. Black, the tegiilse and the legs 

 in part, yellow; head and thorax coarsely, umbilicately pmictured; 

 carina at front of malar space dividing before reaching eye, one branch 

 rmniing up anterior orbits the other directed backward; there is also 

 a branch running to eye; malar space weakly sculptured; depressed 

 apical margin of scutellum emarginate; lateral projections on pro- 

 podeum obsolete; wings subhy aline; front and intermediate legs 

 beyond middle of femora, a large spot at apices of hind femora, hind 

 tibiae, except bases and a median black annulus, and hind tarsi 

 entirely, yellowish ; hind coxse without a tubercle ; hind femora on 

 inner side distinctly, finely, closely punctured and without a tubercle 

 on inner side near base; lower margin of hind femora with a large 

 triangular tooth near middle and between it and the apex eight or 

 nine smaller ones. 



Male. — Length about 4 mm. Similar to the female, except in 

 secondary sexual characters. 



Tij'pe-locality. — Wisconsin. 



Other locality: Massachusetts. 



Types reared from tachinid puparia from Pine Tussock moth at the 

 Gipsy Moth Laboratory at IMelrose Highlands, Massachusetts, and 

 recorded under their number 4623 Bb (female) and 4628 D (male). 



Seven paratopotypes with the same record are recorded under 

 numbers 4610a, 4650 Ta, 4651 Ta (one each); 4655 T (four). 



Five paratypes under numbers 4355 A, 4338 E, 493, 1280 ai, from 

 Massachusetts were reared from puparia of Compsilura concinnata. 



Type.—Csit. No. 13802, U.S.N.M. 



This species has the malar carina and the markings of the hind 

 legs about as in paraplesia and minuta but the absence of the tubercle 

 on the hind femora and the distinct close punctures of the inner side 

 of the hind femora readily separates them. The males are harder to 

 separate from the males of the other species but the absence of the 

 lateral projections on the propodeum added to the other characters is 

 satisfactory. 



CHALCIS THRACIS, new species. 



Male. — Length 5 mm. Black; tegulse, Imees, bases and apices of 

 front and middle tibise, a Ime on front of anterior tibise, spot at apex 

 of hind femora, a spot on outer side near base of hind tibiae and one at 

 apex and all tarsi, yellow; carina at front of malar space dividing
