TWO NEW NOMADID^ (HYMENOPTERA) FROM 

 SOUTH AMERICA. 



By C. Schrottky. 

 Puerto Bertoni, Paraguay. 



I. Epeolus osiriformis, new species. 



Black ; clypeus, base of antennae, tegulse, legs and scutellum reddish. 

 White tomentum on face, pleur3e, middle segment, legs and also in the 

 thoracic sutures ; two longitudinal lines of white tomentum on the meso- 

 notum, transverse lines, more or less interrupted in the middle, on the apical 

 margins of abdominal segments 1-4 (J) or 1-6 ((^), lateral patches on 2-5 

 (5) and another transverse line at the base of first segment (2(^)- Wings 

 hyaline with the outer margin broadly fuscous. 



Female. — Head nearly as broad as thorax ; face densely clothed with white 

 tomentum ; vertex nude, strongly punctured, its posterior margin emarginate and 

 clothed with white pile ; the outer orbits throughout with fine downy yellowish- 

 white pubescence. Mandibles red with black tips. Labrum nude, dusky, 

 finely but closely punctured, with a depression in the middle, clothed with 

 short downy pubescence, Clypeus red, twice as broad as long, its anterior 

 margin straight. Eyes converging towards base. Posterior ocelli less distant 

 from each other than from the eyes, but more than from posterior margin of 

 vertex. Antennae with the scape red, minutely punctured ; the pedicel ex- 

 tremely short; the first joint of the flagellum almost half the length of the 

 second which is longer than any of the succeeding joints. 



Thorax stout, cuboid, although the dorso-ventral axis seems to be the 

 longest. Pronotum reddish, extremely short, lower than the mesonotum. 

 Mesonotum anteriorly broader than long, closely punctured, surrounded by a 

 depressed line which is clothed with whitish pubescence, except on the an- 

 terior margin, rounded towards the pronotum and with red anterior lateral 

 angles. Mesopleurse strongly convex, forming an obtuse edge anteriorly. 

 Calli red and covered with white tomentum. Scutellum nude, rather closely 

 punctured and strongly bituberculate, the depression between the tubercles 

 black, the posterior margin strongly overlapping the metanotum, with a line of 

 white tomentum ; at each side a punctured red spine. Metanotum reddish 

 with two minute tubercles and clothed with whitish tomentum. Middle seg- 

 ment with its basal area nude, divided by a longitudinal rim, punctured only 

 at the sides ; the rest strongly punctured and clothed with white tomentum. 



Abdomen longer than head + thorax, more than twice as long as meso- 

 notum, with a very short, downy, velvety black tomentum and the above de- 

 scribed white markings. The second segment the broadest ; the pygidial plate 

 dark rufous, broader than long, coarsely punctured with elongate rugose punc-
