28 HYMENOPTERA. 



4. Podium bellum. (Tab. n. figg. 17, 17 a.) 



Nigrum, sparse villosum et pilosum ; clypeo inciso, bidentato ; metanoto transverse striato ; cellula cubitali 



2 a latiore quam longiore ; alis fusco-maculatis. $ . 

 Long. 21 millim. 



Hob. Panama, Bugaba {Champion). 



Face rather densely covered with a silvery-white pubescence ; the front and vertex 

 almost glabrous, impunctate ; the incision in the clypeus is broad and deep, the teeth 

 stout. Pro- and mesothorax sparsely punctured, shining, covered (but not very thickly) 

 with rather long, soft, white hair, the metanotum with a shorter, closer, and thicker 

 pile. Metanotum punctured and transversely striated, the centre very slightly depressed. 

 Prothorax narrowed in front, longer than broad, nearly as long as the mesothorax to 

 the middle of the scutellum, its sides behind obliquely striolated. Abdomen slender, 

 acuminate, scarcely one fourth longer than the petiole. Petiole curved, three times 

 the length of the hind coxae, sparsely pilose, shining. Legs downy, the coxae with 

 rather long pale hairs, the tibiae almost without bristles, the tarsi with stout bristles. 

 Wings smoky-violaceous, clouded at the transverse basal nervure, below the stigma at 

 the second cubital cellule, and at the apex ; second cubital cellule broader than long, 

 narrowed above; the first recurrent nervure almost interstitial, the second received 

 before the middle of the cellule. 



This species forms a transition to Trigonopsis, the only difference being that the head 

 is not so triangular. 



5. Podium rufipes. (Tab. II. figg. 18, 18 a.) 



? Podium rufipes, Fabr. Syst. Piez. p. 183. 



Podium rufipes, Saussure, Reise de Novara, Hymen, p. 36 1 ; Cresson, Trans. Amer. Ent. Soc. iv. 

 p. 211 2 . 

 Eab. North Amekica, Texas 2 . — Mexico \ Atoyac in Vera Cruz (Schumann), Temax 

 in North Yucatan (Gaumer). — Brazil. 



In the male of this species the head and thorax are covered rather densely with long 

 black hair; the clypeus and cheeks have a velvety pile; the clypeus is incised in the 

 middle, and has a tooth on either side of the incision ; the mandibles are black ; the 

 wings are much more suffused with fuscous and have a violaceous tinge, and the 

 nervures and tegulae are blackish. 



The Brazilian P. denticulatum, Smith, is very closely allied to P. rufipes (if the two 

 be not one and the same species), but differs from it in the clypeus having six teeth in 

 the female ; as in P. rufipes, the clypeus in the male has only two teeth and the 

 body is more pubescent in the male than in the female.
