subequal and slightly longer than the subequal fifth and sixth; labial 

 palpi s-jointed, the basal joint small, the second joint slightly longer 

 than the remaining subequal ones ; no process between the bases of 

 the antennae ; antennae slender, nearly of equal width throughout, the 

 apical joints slightly arcuate, the third joint much shorter than the 

 fourth, antennae when stretched posteriorly reach nearly to the apex 

 of propodeum ; pronotum about two-thirds the length of the scutellum, 

 sharply truncate anteriorly; propodeum rounded laterally, not sharply 

 oblique from the metanotum ; anterior coxae with the ventral aspect 

 not concave; second recurrent vein about half the length of the 

 second transverse cubitus from the base of the third cubital cell ; 

 tarsal claws with a tooth near apex ; gaster elongate, smooth, no con- 

 striction between the segments ; ventral segments without spines ; 

 hypopygidium nearly twice as long as the width at the apex, gently 

 widening apically, bounded laterally by strong ridges which join with 

 the lateral teeth, median tooth longer and more slender than the lat- 

 eral ones, a prominence in the basal middle ; seventh dorsal segment 

 not flattened or produced. 



In Turner's table this runs to Elidothynnus Turn., but differs 

 from his description by the 5 -jointed labial palpi, and differently 

 shaped hypopygidium. 



Aelothynnus multiguttatus Ashmead. 

 Can. Ent, p. 101, 1903. 



The characters given by Ashmead in his table of the genera 

 of Thynnidse (AN. ENT., June, 1903), are sufficient to satisfy 

 the technical requirements so this species should date from 

 that time and be accredited to Ashmead. The following char- 

 acters may aid in its determination. 



Male. Length 7.5 mm. Clypeus shining, impunctate; front con- 

 fluently punctured, the upper part more sparsely so ; posterior orbits 

 and vertex shining, almost impunctate; fourth antennal joint slightly 

 shorter than the fifth ; anterior face of the prothorax shining impunc- 

 tate ; pronotum, mesonotum, scutellum, mesopleurae shining, with dis- 

 tinct well separated punctures ; propodeum rather closely punctured, 

 punctures in some places confluent so as to appear striate; apical dorsal 

 segment irregularly punctured; lateral lobe of the hypopygidium, tri- 

 angular, obtusely rounded. Black ; base of mandibles, clypeus except 

 a median spot, a spot at the inner base of each antenna, narrow inner 

 orbits to near top of eye, line on posterior and anterior margin of pro- 

 notum, tegulae, a line below spot on scutellum, metanotum (postscu- 

 tellum of authors), a spot above the middle and posterior coxae, spots 

 on lateral apical dorsal angle of first segment, a band on apical dorsal
