polished and moderately hairy; mesoscutum with a distinct deep dimple- 

 like impression posteriorly, the parapsidal grooves distinctly impressed at 

 the lateral anterior angles of mesoscutum but mostly effaced on the dorsum; 

 mesopleura smooth, without a distinct impression below the middle; pro- 

 podeum rugoso-punctate, opaque, without longitudinal carinae; stigma of 

 forewing long and narrow; radial cell long, terminating slightly before the 

 extreme wing-apex; first abscissa of radius distinctly longer than the width 

 of stigma opposite, second abscissa approximately one and one-half times 

 as long as the first intercubitus ; second cubital cell long, not narrowed at 

 apex; recurrent nervure joining the second cubital cell, the abscissa of 

 cubitus between first intercubitus and recurrent vein nearly as long as the 

 nervulus, first brachial cell closed at apex; abdomen about as long as the 

 thorax; ovate, first tergite about as long as broad at apex, distinctly though 

 rather irregularly longitudinally striate, and bicarinate basally; coalesced 

 second and third tergites with the suturiform articulation distinct though 

 not deeply impressed; second tergite throughout and basal one-third of 

 third tergite strongly longitudinally striate, the striae terminating abruptly; 

 apical two-thirds of the third tergite and all of the following tergites polished ; 

 ovipositor protruding beyond the apex of abdomen approximately four- 

 fifths the length of abdomen. General color blackish; head, antennal flagel- 

 lum, dorsum of thorax, propodeum, and ovipositor sheaths black; the pos- 

 terior middle of mesoscutum and region surrounding scutellum more or less 

 piceous; first tergite for the most part, lateral margins of second arid third 

 tergites, apex of third and the following tergites entirely, piceous or black- 

 ish; scape, pedicel, more or less of clypeus, mandibles except at apex, pro- 

 notum, pleura for the most part, legs including all coxae, and the abdomen 

 except as noted, fusco-testaceous to reddish testaceous; hind tibiae and 

 apical joint of all tarsi fuscous; wings hyaline, venation blackish with the base

-Type locality. Victoria, British Columbia. 



Type. Cat. No. 22372, U. S. Nat. Mus. 



Host. Rhagoletis pomonella Walsh. 



Described from four female specimens reared by Mr. W. 

 Dowries, of the Canadian Department of Agriculture, from pupae 

 of the above-named host. A single paratype deposited in the 

 national collection of the Dominion of Canada at Ottawa, Canada. 

 Holotype and two paratypes in the U. S. Nat. Mus. Named in 

 honor of the collector. 



Opius richmondi, new species. 



Runs to category 22 in the writer's key (1. c.) and agrees fairly 

 well with the first alternate. The infuscation on the wing is 

 very faint, however, while the ovipositor is exserted slightly more 

 than the full length of the abdomen. This species is still further
