Chapada. This species is deep opaque black, except the two 

 oblong ovate yellow spots on second segment and the silvery stripe 

 on middle of apical segment. 



57. M. (liophtlialina Kliig (Nova Acta Cses. Nat. Cur., x, p. 318, pi. sxiii, 

 fig. 6). — 9. — Length 10-13 mm. — Slender; head transverse, as broad as thorax ; 

 eyes rounded, very convex; thorax gradually narrowed to apex which is sub- 

 compressed, longitudinally rugose, lateral margin unarmed, anterior angles not 

 acute; abdomen deeply, rather sparsely punctured ; first segment subnodose and 

 subconstricted at apex, the two nude shining rounded spots on sectond segment 

 with a few sparse deep punctures; second ventral segment polished, sparsely 

 punctured, convex at base. 



Velvety black, the pubescence black, erect or suberect and scattered ; a band 

 between the eyes, a stripe on each side of meso- and metathorax above, broad on 

 the former, lower half of tlanks, a spot on each side of basal segment of abdomen 

 above, extreme lateral margin of second segment, a spot on lateral apical corner 

 of segments 2-4, and a spot on apical middle of segments 2 6, small on 2, all of 

 pale golden or silvery pubescence; the two nude spots on second segment above 

 yellowish; legs with pale glittering pubescence; calcaria pale ; ventral segments 

 2-4 fringed at apex with pale pubescence. 



Santarem ; Chapada (April). A specimen from Chapada has 

 no pale band on the head, and is larger; otherwise there appears 

 to be no ditference. 



58. M. bellicosa 9 • — ^Length 9-10 mm. — Form and sculpture of bellica, ex- 

 cept that the second segment of abdomen is more coarsely punctured and the 

 eyes more prominent. 



Black, with short black pubescence; head with golden pubescence above, paler 

 on sides; a pale golden pubescent stripe on each side of thorax above, not reach- 

 ing prothorax ; lower part of flanks silvery, the upper part smooth and polished ; 

 legs with pale glittering pubescence, calcaria white ; a spot on disk of first seg- 

 ment of abdomen and on apical middle of the second, silvery pubescent; second 

 segment above with two large elongate shining blood-red, sparsely punctured 

 spots, narrowed anteriorly and reaching the basal margin ; apical segments with 

 pale glittering pubescence, extreme sides of second and following segments, as 

 well as the venter, with silvery pubescence. 



Chapada. This is larger than belli/era to which it is allied ; the 

 head, however, is golden, and the first segment of the abdomen above 

 has a pale spot on disk and another on apical middle of second ; the 

 red spots on second segment have the sides less parallel, while the 

 black stripe does not extend beyond the silvery spot on apex of the 

 segment. 



59. in. bellifera 9-— Length 6-7 mm.— Form rather slender; head as 

 broad as thorax, transverse; eyes subovate, prominent, convex, approaching pos-
