of the tegulae, a spot on the mesopleurae below the anterior wings, 
a spot on the scutellum sometimes absent, the postscutellum, a narrow 
longitudinal band on the middle of the median segment, a large 
spot on each side at the apical angles extending on to the pleurae, 
the sides of the first dorsal abdominal segment very broadly, the 
sides of the second and third segments, except at the extreme base, 
connected by a band sharply narrowed on the middle half or third 
close to the base, the narrowing of the band forming a wide emargi- 
nation posteriorly, the sides of the fourth segment connected by a 
band near the base very narrowly and shallowly emarginate posteri- 
orly in the middle, the fifth segment with a large transverse black 
spot on each side, a spot at the apex of the posterior coxae, the 
apical half of the femora above and the anterior femora above yellow; 
the mandibles, except at the apex, a spot on the tegulae, the tibiae, 
tarsi, femora beneath and extreme apex of the pygidium ferruginous; 
antennae fusco-ferruginous. Wings hyaline, without any darker colour 
on the costa, slightly tinged with yellow; nervures ferruginous. 
The second cubital cell is longer than the third on the radial 
nervure and receives the first recurrent nervure much beyond the 
middle, the second recurrent is received near the middle of the third 
cubital cell. 
Length 15—19 mm. 
Hab. Asuncion, Paraguay (Anısırs).. 2 specimens. January. 
The second specimen has the yellow markings considerably 
reduced in size. 
The probable male of this species has the usual yellow markings, 
the abdominal bands being narrower than in maculatissima, but in 
addition there is a small yellow spot on the vertex, two small yellow 
spots close to the base of the median segment, a quadrate spot on 
the middle of the apical abdominal segment and a wedge shaped 
spot on each side of the same segment; the abdomen is strongly glossed 
with blue reflections, the ventral surface being black without yellow 
bands which are only represented by a large spot at the apical 
angles of segments 2—6. The emargination of the apical segment 
is rather deep, the spines at the angles long, the apical half of the 
segment before the emargination is slightly concave, smooth and 
shining. First abdominal segment long and slender as compared with 
maculatissima. The second recurrent nervure is received near the 
base of the third cubital cell. Wings clear hyaline; nervures black, 
testaceous at the base and on the costa.
