from a larva believed to have been Pyrausta ainsliei, boring the stem 

 of Polygonum.^ sp., and received from E. M. Searls, Schenectady, New 

 York. 



Five specimens of what appears to be the same species were reared 

 at Ipswich, Massachusetts. July 21, 1921, from Pyrausta nuhilalis by 

 H. L. Parker. Also fifteen specimens reared by G. G. Ainslie at 

 Knoxville, Tennessee, in July, 1919, from Pyrausta genitalis are ap- 

 parently the same species. The two series last mentioned are not 

 considered a part of the type material. 



MICROBRACON PAPAIPEMAE, new species. 



This species resembles furtlvus Fyles but is readily distinguished 

 by the weaker sculpture on the abdominal tergites and the generally 

 darker color. 



Female. — Length 3.2 mm. Head transverse; vertex, cheeks, pos- 

 terior orbits, and occiput smooth and polished; frons and face 

 uniformly finely coriaceous; antennae 27-jointed, in the type the first 

 flagellar joint slightly the longest, hardly twice as long as thick; 

 following joints all distinctly longer than thick; mesoscutum and 

 scutellum polished, sparsely hairy ; propodeum polished, with three 

 to four short upward directed and divergent striae on each side of 

 the apical middle; pleura smooth and polished; abdomen about as 

 long as head and thorax, a little broader than thorax at its widest 

 point; first tergite not quite as broad as long, the sides nearly 

 parallel, slightly constricted at base, the embossed apical portion as 

 well as the posterior lateral margins rugulosely sculptured; suturi- 

 form articulation moderately deep and straight, not angulated at 

 the middle; second tergite rather strongly sculptured with a few 

 indistinct longitudinal rugae on each side of the middle, the anterior 

 middle with a very small embossed area ; tergites beyond second all 

 weakly sculptured and more or less shining; ovipositor exserted 

 approximately the length of the whole body; stigma of forewing 

 broad, lanceolate-ovate ; first abscissa of radius slightly shorter than 

 the breadth of stigma; second abscissa fully twice as long as first 

 and distinctly longer than the first intercubitus ; radial cell terminat- 

 ing somewhat in front of the extreme wing apex. General color 

 shining black; frons and more or less of the vertex piceous or brown- 

 ish; face, malar space, and lower part of cheeks testaceous; antennae 

 entirely brownish black; thorax mostly black; scutellar region and 

 pleura more or less piceous; legs including all coxae reddish tes- 

 taceous; hind tibiae and tarsi piceous black, the base of tibiae tes- 

 taceous; abdomen black dorsally; lateral margins of first segment, 

 margins of second, and the suture separating second and third 

 tergites pale testaceous ; abdominal venter and the ovipositor sheaths 

 brownish testaceous: wings subh valine, the venation dark brown.
