Soolia (Discolia; versicolor Sauss. 



Chapada (November and March.) Four 9 and one S specimen. 

 Saussure in describing this species was in doubt whether its habitat 

 was Brazil or Africa. The specimens before me agree very well with 

 the description, and leave no doubt in my mind as to their identity. 

 The color of thorax varies somewhat, the dorsulum, tegulre and scu- 

 tellum sometimes partaking of rufous. 



The male has not before been recorded. It may be briefly diag- 

 nosed as follows : 



$ . — Colored like the 9 , but with four apical segments reddish ; 

 antennffi stout, about as long as head and thorax ; thorax strongly 

 punctured, sparsely so on dorsulum, scutellum, metanotum and 

 middle segment, medially ; abdomen with strong punctures, fairly 

 close, on dorsal segments 4-6 in the middle somewhat sparsely, the 

 ventrals much more sparsely so ; second ventral at base strongly 

 bituberculate ; longer spur of hind tibia about half as long as the 

 first hind tarsal joint ; wings black, with a strong bluish-purple re- 

 flection ; pilosity of body black, rather sparse. Length 20 mm. 



Scolia (Discolia) Drewseni Sauss. 



Chapada (March and April). Eighteen 9 and fifteen S speci- 

 mens. The wings have a bronzy-purple reflection, not violaceous as 

 described by Saussure. 



The $ , heretofore unknown, may be described as follows : 

 $ . — Similar to 9 as to coloration, the black or under side of 

 thorax more distinct ; antenme about as long as head and thorax ; 

 thorax strongly punctured, sparsely so on the middle of dorsulum, 

 scutellum, metanotum and upper surface of middle segment ; abdo- 

 men with strong punctures becoming closer toward apex, sparsest 

 on first and second dorsal and on the ventral segments ; longer spur 

 of hind tibiae nearly half as long as the first hind tarsal joint; 

 second ventral segment at base indistinctly tuberculate; wings black, 

 with a strong bronzy-purple reflection ; pilosity of body reddish, 

 rather dense on apical abdominal segments. Length 12-18 mm. 



Scolia (Discolia) decepta n. sp. 



Similar to Drewseni, but the wings are deeper blue, and not pur- 

 plish ; clypeus transverse, not produced in the middle as in Drewseni. 



9 . — Head with deep, sparse punctures, almost impunctate above 

 on the front, more closely at base of autennte and on occiput ; clypeus 

 convex and impunctate medially, depressed and punctured on the 

 sides, a small patch of pale hairs on each extreme side ; thorax
