BRUES: PARASITIC HYMENOPTERA. 65 



as thick as the second; following gradually and distinctly wider toward the 

 middle of the flagellum, beyond which they become narrower; those near the 

 middle over twice as wide as long. Mesonotum and pleurae rather closely 

 punctate. Metanotum finely granular, completely areolated. Abdomen 

 nearly twice as long as the head and thorax combined, clavate, gradually 

 enlarged to the tip. First and second segments with two complete discal and 

 a lateral carina, those on the first regularly convergent apically. First seg- 

 ment nearly as long as the slope of the metathorax; second and third of about 

 equal length, but higher; following nearly as long and gradually higher. Ovi- 

 positor short and very slender, scarcely projecting. Posterior legs rather long 

 and stout. Wings hyaline. Stigma and veins pale. Stigma long, almost 

 linear; marginal cell extremely long and narrow. Areolet open; cubitodis- 

 coidal cell long and narrow. Submedian cell a little longer than the median; 

 first recurrent nervure curved, strongly oblique, broken below the middle. 



Type.— No. 2240, M. C. Z., Florissant, Col. (No. 5963, S. H. 

 Scudder Coll.). This is a very large conspicuous species and seems 

 without any doubt to belong here. 



Tylecomnus pimploides, sp. nov. (Fig. 49.) 



Female. Length 14-16 mm. Apparently entirely dark colored although 

 the type specimen is irregularly discolored and shows yellowish markings. 

 Antennae long and stout, tapering, with very many joints; second and third 

 flagellar joints each but little longer than wide; joints toward the middle

about half wider than long; apical joints smaller, about quadrate. Head 

 large, broadly transverse; face densely-punctate. Mesonotum with deeply 

 impressed parapsidal furrows which are widely separated at the base of the 

 scutellum. Pleurae in front strongly horizontally wrinkled. Scutellum 

 strongly convex, the depression at its base with high carinae laterally. Meta- 

 notum above with four carinae which separate large oblong median, lateral 

 and pleural areas. Posterior edge with a transverse carina and posterior face 

 with a short median carina that separates two small areas. Abdomen very 

 broad at the base; first segment a little less than twice as long as wide, with
