TACHYTES FUNDATUS, new species. 



Wings f ulvo-hyaline ; pubescence of the head and thorax fulvous; 

 hair of pygidium dark bronze-color; four posterior tibiae reddish- 

 brown. 



Female. — Length 20 mm. Anterior margin of the clypeus gently 

 rounded, with three obtuse teeth on each side of the median area; 

 the notch on the exterior margin of the mandibles very distinct; no 

 line from the anterior ocellus; front with small, irregular punctures, 

 vertex with the punctures hardly as distinct as those on the front; 

 space between the eyes at the vertex hardly as great as the length of 

 the first flagellar joint; first flagellar joint but very little longer than 

 the second ; pedicel not twice as long as wide ; mesonotum, scutellum, 

 and propodeum with small, close, irregular punctures; scutellum, 

 metanotum (postscutellum of authors) and the dorsal aspect of 

 propodeum with an impressed longitudinal line, which broadens into 

 a triangular fovea at the apex of the propodeum ; legs rather strongly 

 spined ; third cubital cell a Httle longer than the second on the radius ; 

 dorsal segments dulled by fine longitudinal scratches; ventral seg- 

 ments shining basally, irregularly punctured apically; pygidium 

 rounded at the apex. Black; tegulse and legs below femora red or 

 reddish-brown; head and thorax with long fulvous hair and pubes- 

 cence; hair of pygidium bronzy. Wings f ulvo-hyaline, venation 

 reddish-yellow. 



Male. — Length 16.5 mm. Anterior margin of the clypeus slightly 

 produced in the middle, otherwise as in female; space between the 

 eyes at the top not more than two-thirds the length of the first 

 flagellar joint; emargination of the seventh ventral plate arcuate, 

 lobes broad, obtuse; hair of the pygidium silvery; hair on thorax 

 not so dense. Except where mentioned the male agrees with female.

TACHYTES AUROPILOSUS, new species. 



Head and thorax with bright golden pile, abdomen with silvery; 

 scape and legs below the coxse red; wings dark brown. Perhaps 

 most closely related to Tachytes proxima Nurse (1903), but the scu- 

 tellum and upper surface of the propodeum have an impressed line in 

 that species and the wings are ''flavo-hy aline." 



Female. — Length 17 mm. Anterior margin of the clypeus gently 

 rounded, without teeth; mandibles with the exterior notch almost 

 wanting, the broad basal part rounded off gradually; space between 

 the eyes at the vertex about the same as the length of the second and 

 third antennal joints; a faint carina from the anterior ocellus to
