dorsulum minutely, closely, indistinctly punctured; scutellum sparsely punc- 

 tured ; mesopleura shining, closely punctured, with two grooves on the superior 

 half, the posterior groove nearly parallel with the posterior margin of the sclerite 

 and nearly at right ang'les to the broader anterior groove, which attains the an- 

 terior margin of the sclerite. Metanotum rather shining, somewhat roughened 

 with a transverse carina near the base and a longitudinal Y shaped carina in the 

 middle, forming with the basal carina the medial area or areola, which is nearly 

 quadrangular, an inverted V-shaped carina on each side of the basal half of the 

 metanotum; metapleura, with separated punctures, dullish; wings faintly 

 brownish, nearly clear, stigma brownish testaceous, nervures dark brown ; cubito- 

 discoidal nervure broken in the middle; the first recurrent nervure less than 

 one-half the length of the second recurrent nervure; transverse median nervure 

 interstitial; transverse median nervure in posterior wings broken a trifle below 

 the middle. Claspers rather broadly rounded at apex. Pubescence and abdo- 

 men as in E. felti. Ferruginous; orbits yellow; mandibles black at tip; legs 

 paler, more testaceous than the thorax; venter more or less black; flagellum 

 dull pale brown.

Thyreodon morio Fab. 



Douglas county, Kansas; V. L. Kellogg. 

 Thyreodon snowi, n. sp. 



Female. — Length, 25 mm. Head somewhat broader than in morio; the face 

 more even, a small tubercle in the middle of the face a little below the insertion 

 of the antennie, face with adjoining punctures, giving a rugulose appearance, 

 punctures along the eye margin distinct; clypeus sparsely, deeply punctured; 

 cheeks shining, distinctly, closely punctured; antennaj sixty -one jointed, scape 

 and pedicellum together a little longer than the first joint of the flagellum. Dor- 

 sum shining, closely punctured, especially on the anterior margin where the 

 punctures are so close as to give a rugulose agpearance; parapsidal grooves dis- 

 tinct, rugose, forming a U and not attaining the posterior border; scutellum 

 closely punctured, traversed by an arcuated raised line describing a semicircle; 

 mesopleura closely punctured, nearly rugulose below, area along the upper half 

 of the posterior border of the mesopleura polished, impunctate; metanotum 

 rugulose, the posterior face with a median transversely striate groove; meta- 

 pleura distinctly, closely punctured, wings fuscous, not as dark as in morio, a 

 broad bare yellow area in the middle of the anterior half of the posterior wings ; 

 neuration nearly ae in morio, the transverse median nervure of the posterior 

 wings broken nearer the median nervure than in morio. Petiole smooth and 

 shining, sparsely, minutely punctured, the remaining segments of the abdomen 

 as in morio. Covered with inconspicuous pubescence, blackish or brownish on 

 the dark portions, golden brown on the pale parts. Black ; orbits, cheeks, an- 

 terior margin of the dorsulum, superior anterior and posterior margin of the 

 mesopleura brownish ; antennte orange as in morio, scape and pedicellum brown ; 

 four anterior legs with the terminal trochanter, femora, tibiae and tarsi almost 

 entirely and posterior tibite and tarsi brownish testaceous, middle and posterior 

 legs with the apical tarsal joint brown.
