STUDIES IN THE FOSSORIAL WASPS. 723 



segments are very sparsely punctaired, with a row of piliferous 

 punctures near the apex ; the pubescence is whitish. 



Hah. San Juan del Rey, Brazil [Selloiv). Two specimens. 



Ty23e in the Berlin Museum. 



Elis major, sp. n. 



$ . Nigra ; fascia angusta transversa sicpra antennas, margine 

 interiors oculorum anguste, linea pone ocidos, postscutello, segmentis 

 dorsalibus prima secundoque macula magna ohliqua lUrinque, 

 segmentisque 3-5 fascia lata sub-hasali flavis ; mandibidis, tihiis 

 tarsisqioefitscis; cdis jlavo-hyalinis, venis testaceis. 



Long. 24 mm. 



2 . Clypeus coarsely punctured, broadly rounded at the apex, 

 raised and longitudinally carinate in the middle. Front coarsely 

 jjunctured, the prominence between the antennee almost trans- 

 verse at the apex, vertex and ocellar region a little more sparsely 

 punctured, cheeks very sparsely and more finely punctured ; 

 posterior ocelli nearly twice as far from the eyes as from each 

 other. Thorax closely and coarsely punctiii'ed, especially on the 

 pronotum and mesopleui'8? ; propleur£e finely obliquely striated. 

 Median segment smooth, opaque, rugosely punctured in the 

 middle, with a few irregular transverse striae at the apex and 

 also on the sides of the posterior truncation ; the sides of the 

 segment striated, with a small yellow band near the apical angle. 

 Abdomen shining, with a few scattered punctures, the apical 

 segment closely longitudinally striated and broadly rounded at 

 the apex. Ventral segments smooth, more or less punctured at 

 the apex. First and third abscisste of the radius about 

 equal in length, the second nearly half as long again. First 

 recurrent nervure received beyond the middle, sometimes at 

 two-thirds from the base of the second cubital cell, second 

 received between the middle and one-quarter from the base of 

 the third cubital cell. Calcaria whitish. 



Hab. Centi'al Bi^azil (Selloio). 



Described from three specimens in the Berlin Museum. 



The probable male of this species has the usual yellow markings : 

 the mandibles, clypeus, a small spot on each side above the base 

 of the antenna), the margins of .the pronotum, interrupted in the 

 middle on the anterior margin, the tegulai, a spot on the meso- 

 notum, one on the centre of the scutellum, a large spot on the 

 mesopleuree below the anterior wings and another before the 

 intermediate coxfe, the postscutellum , a lateral longitudinal band 

 on each side of the posterior slope of the median segment, apical 

 bands on dorsal segments 1-6, straight and nai'row on segments 

 4-6, broader and shallowly emarginate on segments 2-3 and very 

 deeply emarginate on the first segment, the tibia?, tarsi, and the 

 greater part of the femora yellow. No yellow spots on the apical 

 segment. Wings hyaline, nervures black. Emargination of the 

 iLpical segment broader at the apex than deep, the dorsal surface
