AKT. 15. KEVISIOIs^ OF ICHNEUMON-FLIES MUESEBECK. 11 



Washington, District of Columbia; Jacksonville, Florida; Ithaca, 

 New York. 



The National Collection contains only the two specimens of the 

 type series, the type from Washington, District of Columbia, and the 

 allotype from Jacksonville, Florida. I have also seen one male and 

 one female of this species in the Cornell University Collection, 

 reared at Ithaca, New York, from Lithocolletes aceriella Clemens. 



3. MIRAX TEXANA, new species. 



Eeadily separated from aspidiscae, to which it is apparently closely 

 allied, by the entirely yellow head, and the reticulated propodeum. 



31 ale. — Length, 1.2 mm. Head a little broader than thorax, 

 strongly receding behind the eyes, mostly smooth and shining; an- 

 tennae about as long as the body, the first flagellar segment distinctly 

 longer than the second; vertex without a median groove from the 

 median ocellus to the occiput; parapsidal furrows deeply impressed 

 anteriorly, wholly wanting behind; mesoscutum and scutellum 

 mostly smooth, with only a few weak punctures; mesopleurae 

 polished; propodeum reticulate with a median longitudinal carina, 

 the interstices smooth and shining; stigma large, triangular, the 

 first cubital and first discoidal cells broadly confluent ; radius almost 

 wholly obliterated; legs slender; posterior coxae short; spurs of 

 posterior tibiae very short; abdomen about as long as thorax, de- 

 pressed, slender at base, broadening suddenly at apex of first seg- 

 ment; the embossed plate on the first tergite very slender, and nar- 

 rowing to a point at apex; second tergite almost entirely mem- 

 braceous, the embossed plate being nearly reduced to a line on the 

 anterior three-fourths; but broadening suddenly posteriorly so that 

 it extends entirely across the tergite; entire abdomen smooth and 

 shining. Head, including the antennae, wholly yellow; thorax 

 brown, tegulae pale; wings hyaline, the veins and stigma pale yel- 

 low; legs, including all coxae, yellow; abdomen pale on basal half, 

 blackish beyond.
