BRAZILIAN MUTILLA. 73 



and feebly punctured, shining, a little pale pubescence on basal and apical corners 

 of segments 2 and 3; beneath shining, the first segment subdentate near apex, 

 the second deeply and sparsely punctured, with a broad ovate, black pubescent 

 fovea on disk, the pubescence black, slightly mixed with pale. 



Chapada (February). Two specimens. 



29. HI. caxara 'J. .—Length 15 mm.— Black, opaque, the pubescence black, 

 mixed with pale on front and clypeus. Eyes round, convex. Scutellum promi- 

 nent, with a smooth, shining tubercle on disk, the lateral teeth rather short and 

 compressed; an obtuse tubercle beneath tegulse; metathorax reticulated, upper 

 surface flattened, sides subangulate when viewed from beneath, the pubescence 

 long and pale, a large silvery tomentose patch on each side of the disk; tegulse 

 polished. Wings fuscous, paler at base, the neuration much as in vidua, except 

 that the third submarginal cell is much more narrowed beneath. Legs witli pale 

 glittering pubescence, dense on tibife and tarsi ; calcaria white. Abdomen with 

 first segment nodose and constricted at apex, the pubescence long and pale, and 

 when viewed from the front with two sniHll silvery tomentose spots on apical 

 margin ; second segment feebly punctured, rather shining, with a few pale hairs 

 on basal corners and also on apical corners of segments 2-4 ; beneath shining, 

 basal segment with a short acute tooth near apex; second segment shining, 

 deeply and sparsely punctured, the pubescence short, sparse and pale, a large 

 elongate black pubescent fovea a little before the middle, apical margin of seg- 

 ments 2-4 densely fimbriate with white hair. 



Chapada (March). One specimen. Larger than lorena which 

 it resembles, but easily separated by the pubescence of the tibiae and 

 tarsi being entirely pale. 



30. M. caneta % .—Length 17 mm.— Rather large, black, the pubescence 

 black. Eyes round and convex. Scutellum prominent, with a shining discal 

 ridge, lateral teeth short; metathorax coarsely reticulated, pubesence long and 

 pale, a patch of dense white pubescence on each side above; a prominent obtuse 

 tubercle beneath tegulse. Wings fuscous, paler in the cells and with the base 

 conspicuously hyaline ; neuration much as in vidua, except that the third sub- 

 marginal cell is smaller and more narrowed beneath. Legs with pale glittering 

 pubescence; calcaria white. Abdomen with the basal segment elongate, nodose 

 and constricted at apex, the pubescence long, pale and silky, on each side of the 

 segment an elongate spot of dense, recumbent silvery-white pubescence, continued 

 iu a stripe on basal half of second segment, the latter shining, finely alutaceous ; 

 a patch of dense silvery white pubescence on sides of third segment, covering 

 also the narrow lateral margin of the second ; beneath polished, first segment 

 carinate and briefly dentate at either end of the carina; second segment sparsely 

 punctured with an ovate pubescent fovea on middle; apical margin of segments 

 2 and 3 fimbriate with white pubescence. 



Chapada (October). Two specimens. A very distinct species, 

 easily recognized by the stripe of white pubescence on each side of 

 second abdominal segment at base above.
