and only half the length of the petiole; the basal joint of hind tarsi only 

 twice the length of the second; the submedian cell is as long or slightly 

 longer than the median cell, the length of the transverse median ner- 

 vure; while whereas, in p. gem'inatus there is always a distinct stump 

 of a vein at the middle of the cubitus, in P. texanus it is entirely wanting 

 or only the base remains.

Biologi;i Centrali Americana; Hymencptera, I, 188(3, p. 303. 



Fuscous, testaceo variegatus; capite flave; pedibus pallide testaceis, 

 coxix posterioribus femoribusque posticis fuscis; alis fumatis, stigmate 

 testaceo. Female, Long. 15 millim. 



Hab. Panama. Volcan de Chiriqui 20(JU to 30(JU feet (Champion). 



Antennae a little longer than the body, microscopically pilose; the 

 fiagellum dark fuscous, the scape testaceous. Head yellow, the occiput 

 dark fuscous; the ocellar region black; the face obscurely punctured, 

 projecting in the middle; mandibles testaceous, the tips black; palpi 

 yellow. Thorax dark fuscous; a line on the pronotum, the sutures of 

 the mesonotum, a mark below the tegulae, the sides of the scutellum, 

 and the lower part of the metapleura, pale testaceous. Metathorax closely 

 transversely striated. Abdomen fuscous, the base of the first three 

 segments and their ventral surface pale testaceous. Wings with a 

 fuscous- tinge; areolet minute, not oblique; the recurrent nervure 

 interstitial. 



Differs from P. geminatus in the fuscous colour of the body 

 in the wings having a decided smoky tinge, in the expansions 

 on each side of the metathorax being much more distinct, in 

 the abdomen being broader and not so compressed, and in the 

 petiole being thicker and shorter compared to the second seg- 

 ment.
