170 HYMENOPTERA. 



Abdomen shorter than the thorax, subpetiolate. Legs moderately stout, pilose ; the 

 spurs stout, the long spur on the hinder tibiae reaching a little beyond the middle of the 

 metatarsus. Antennae moderately stout, the middle joints slightly dilated. Wings: 

 the second cubital cellule at the top and bottom a little longer than the third; the first 

 and third transverse cubital nervures curved, the second almost straight; the first 

 recurrent nervure received close to the centre, the second in the apical fourth of the 

 cellule ; the lanceolate cellule wide, the apex lanceolate.

Had. Mexico, Teapa in Tabasco (H. II. Smith). 



Similar in coloration to P. teapce, but smaller ; the fore tibiae and tarsi black ; the 

 median segment much more rounded, the basal half not having such a sharply oblique 

 slope ; the second cubital cellule at the top and bottom distinctly shorter than the 

 third ; the recurrent nervures both received before the middle of the cellule ; the basal 

 nervure not interstitial ; the long spur of the hind tibiae not reaching the middle of the 

 metatarsus. Eyes scarcely arcuate at the top, converging beneath; ocelli almost 

 forming a triangle, the posterior ones separated from the eyes by a distinctly greater 

 distance than they are from each other. Clypeus convex, transverse at the apex, 

 the sides rounded. The head has a slight bluish tinge; it is finely and closely 

 punctured, and has a sparse white pubescence on the face ; the occiput is slightly 

 convex. Pronotum arcuated behind, gradually narrowed from the apex. Thorax 

 above alutaceous; the pleurae and scutellum finely punctured; the scutellum broad, 

 flat; the median segment elongated, with a gradual slope. Abdomen short, petiolate; 

 the pygidium covered with long fuscous hairs. Legs pruinose, elongate, slender ; the 

 long spur of the hind tibiae not reaching the middle of the metatarsus; the tarsi 

 thickly covered with stiff pubescence. The second and third transverse cubital cellules 

 are broadly curved ; the second cubital cellule is much narrowed at the top.

Hah. Mexico, Teapa in Tabasco (H. H. Smith). 



Eyes slightly converging beneath. Hinder ocelli separated from the eyes by a some- 

 what greater distance than they are from each other. Clypeus slightly convex, the 

 apex broadly rounded; the labrum projecting, its apex rounded. Occiput transversely 

 rounded. Head densely covered with a rather long whitish pubescence; the front 

 aciculate; a furrow runs down from the ocelli. Thorax aciculate, covered with a
