l)<)lished, with a few large punctures along cephalo-ventral liniits; dorsad of 

 this latter an area of fine, irregular, oblique carinae, limited above by several 

 rows of irregular, subquadrate reticulations. Truncature nearly flat, setace- 

 ous, entirely covered with reticulations. The articulation of petiole directly 

 dorsad of or vertical to metacoxal fossae, the metunaplcura subquadrate in 

 outline. Metasternal processes slightlj^ divergent at distal ends. Posterior 

 tibia and posterior metatarsus with long, stiff spinulae, among the numerous 

 l)ale setae; posterior coxa above with proximal half impunctate, polished, 

 distal half finely punctate and setaceous. Posterior tibial spurs almost equal 

 length, a little over one-third the length of posterior metatarsus; posterior 

 metatarsus much longer than remaining tarsal segments together; tooth of claw 

 shorter than apical ray. Wings hyaline; front wing with one closed subcostal 

 cell, median vein well formed. 



Petiole slightly over twice as long as distance from point of articulation to 

 cephalic margin of propodeum; with sharp longitudinal carinae on dorsal 

 and lateral aspects, intervals between carinae on dorsal and lateral aspects, 

 intervals between carinae polished, almost impunctate; modei'ately setaceous. 

 Abdonuui compressed, polished, with a few pale setae on dorsum. 



One specimen, the holotypc, collected July 1, 1919, iit Prata, 

 Brazil. 



BRACHYGASTER Leach (^Semaeomyin) 



Tlu! <:;enus Brachygader is represented by seven specimens, 

 six of which are from Peru and one from Brazil. Bradley, in 

 1908, erected the genus Semacomyia for the Neotropical sp(;cies 

 of certain Evania and Brachygaster of authors. Bradley also 

 proposed Semaeodogaster for the one species of Brachygaster 

 occurring in Europe, saying Brachygaster was a nomen nudum. 

 According to Kieffer the European B. minuia Olivier is con- 

 generic with the South American species. Viereck, in 1914*^, re- 

 tains the name Brachygaster. 



One spechnen of this genus is not includt'd in ni}^ key or de- 

 scriptions, as it is badly mutilated. It is a female and was 

 collected by Mr. Parisli on ^^lay 18, 1920, at Iquitos, Pjru. 

 Apparently it is closely related to my peruviana and runs to 

 that species in the following key. However, it readily can be 

 separated from peruviana in many ways and i)roba])ly represents 

 another new species.
