Ichneumon (Probolus) flavofacialie, n. ep. 



Superficially related to I. pedalis but apparently near to I. similaris. 



Male. — Length, 13 mm. Head shining ; face and cheeks closely punctured, 

 the cheeks less distinctly and less closely punctured than the face ; clypeus almost 

 impunctuate and smooth, bearing only a few good-sized punctures and some scat- 

 tered minute punctures ; malar space a little higher than the mandibles are broad 

 at base (antennaj broken) ; scape and pedieellum together as long as or a little 

 shorter than the first joint of the fiagellum. Thorax shining; the dorsulum 

 closely punctured, the punctures adjoining or nearly, parapsidal grooves faintly, 

 broadly impressed near the anterior margin: punctures of the mesopleura of 

 about the same size as those on the dorsulum and as close together; punctures 

 practically obliterated, areola rugose, nearly twice as wide as long, with the 

 of the scutellum well separated, rather sparse; metanotum with the basal area 

 Bides almost parallel, petiolarea not defined by raised lines but distinguished 

 from the adjoining areas by the difference in sculpture, the petiolarea being 

 rather finely rugulose or coarsely granular, nearly as wide at apex as at base, 

 the lateral areas rugose and more like the areola in sculpture, the basal lateral 

 areas are sculptured very much like the petiolarea; the metapleura rugoso- 

 punctate; wings distinctly brownish, stigma pale brown, costal margin dark 

 brown, nervures reddish brown; areolet with the first cubital side and the 

 transverse cubiti of equal length, the radial side a little more than half the 

 length of the cubital side. Petiole shining, with the constricted portion rather 

 coarsely sculptured, almost rugosopunctate, the broad portion more dullish 

 and rather finely rugulose, longitudinally divided into three almost equal 

 parts by two distinct ridges ; the remaining segments dull, with shallow adjoin- 

 ing punctures, apical segments shining, with the punctures separated and of a 

 different type. Black; face below antennte, exclusive of the malar spaces, al- 

 most entirely yellow, the black of the front extending around the insertion of 

 the antenna?, forming a transverse black area immediately below the antennal 

 fovefB, from this area a band is prolonged down the middle of the face nearly to 

 the base of the clypeus; clypeus anteriorly with a pale brown spot, labrum 

 brown at base, mandibles yellow only along the superior margin, anterior legs, 

 except coxa3 and trochanters, middle and posterior legs, except coxae and basal 

 trochanters, more or less ferruginous; the posterior legs with the tibiie almost 

 black on the apical fourth, the tarsi fuscous. 



Type: University of Kansas. Type locality ; Manitou Park, Colo. August, 

 1891, F. H. Snow. 



Ichneumon (Barichneumon) egregiafacialis, n. sp. 



Very like the preceding, from which it differs as follows: 



Male. — Length, 12 mm. Face coarsely, closely punctured; clypeus with 

 sparse large and small punctures; vertex and cheeks with well-separated punc- 

 tures ; antennte forty-five jointed, scape and pedieellum together a little longer 

 than the first joint of the flagellum. Dorsulum with the punctures rather sepa- 

 rated ; areola about one and a half times as wide as long, hardly quadrangular, 

 more nearly semicircular, with the posterior margin rather distinctly incurved, 

 petiolarea not very perceptibly different in sculpture from the adjoining areas 

 f rom which it is not separated by distinct raised lines, the petiolarea is constricted 

 below the middle so that it is nearly twice as broad at base as at apex, the petio- 

 larea is granular, the adjoining areas rather rugulose. The petiole of the abdo- 

 men is distinctly as broad as thick at base. The legs, excepting basal trochanter 

 and coxae, are almost entirely yellowish ferruginous, the posterior tibise and tarsi
