APID.i:. 30s 



EPEOLUS, Latr. 



This genu3 consists of comparatively few species, most 

 of which, according to Smith, are American ; they are short 

 and robust in form, the labial palpi are four-jointed, the 

 second joint being about three-quarters the length of the 

 first, two small joints at the apes are deflected and cylin- 

 drical, the apical one shortest, paraglossee elongate at 

 the base, produced laterally into an elongate curved spine- 

 like process, maxillsB blunt at the apex, their palpi only 

 one-jointed, lora well defined but short, submentum elon- 

 gate, labrum subtransverse, bituberculate, antennis short, 

 their joints transverse ; scutellum raised, dentate laterally, 

 much produced posteriorly over the metaaotum, mesopleura3 

 dilated and rounded, propodeum nearly vertical ; abdomen 

 short, subtriangular, variegated with spots of pale pube- 

 scence ; <J with six ventral segments exposed, the seventh 

 truncate, the eighth narrow and tongue like, ? with the 

 sixth ventral segment produced into a long, somewhat 

 spathulate process on each side. This is a character I have 

 not observed in any other genus. The species are parasitic 

 on members of the genus CoUetes.

 Black, head and thorax largely and rugosely punctured, 

 labrum tridentate at the apex, and with two small 

 tubercular teeth near the middle, mandibles pitchy red 

 in the centre, pronotal collar, and two short stripes 

 on the mesonotum in front, clothed with ochreous pube- 

 scence in the ^, with fulvous (soon fading to ochreous) 

 in the ? , mesopleurffi and sides of propodeum with ochreous 

 pubescence in both sexes, tubercles black, rufescent in the 

 ? , tegula3 rufescent, wings slightly dusky, apex darker, 

 nervures testaceous at the base, scutellum red in the ? , 

 much produced in both sexes over the motathorax, with a 

 slight dorsal impression, its lateral angles dentate, propo-
