above, a quadrate spot on disk of segments 4 and 5, and a spot on extreme sides 

 of segments 2 and 3 at apex, all of dense ochraceous pubescence ; two large 

 rounded, almost contiguous, dark red, shining spots on middle of second seg- 

 ment above, and two smaller elongate oblique spots of same color at base, nearly 

 confluent with the larger ones ; sides of apical segments and beneath with long 

 pale hair ; legs with ochraceous pubescence and long pale hair on femora, calcaria 

 black. 



Brazil (no definite locality). One specimen. Same form as 

 centrovittata (No. 35), but separated at once by the large shining 

 red spots on second segment of abdomen. Closely related to vir- 

 ginalis Gerst.

 compressed tooth on middle. 



Black, opaque, the pubescence black; head, broad stripe on sides of thorax its 

 entire length, lower margin of pleura, a dot on sides of first abdominal segment, 

 extreme lateral margin of second segment, line on lateral apical margin of seg- 

 ments 2-5, and spot on apical middle of same, all griseous or silvery pubescent; 

 antennfe and legs with pale glittering pubescence ; calcaria pale; the four nude

Chapada. 



67. M. chapada 9.— Length 10-13 mm.— Much the same form as latevit- 

 tatn, hut with the metathorax less gibbous, being obliquely declivous posteriorly,

 head generally with a longitudinal tuft of fulvous or golden pubescence on vertex,

 densely silvery pubescent, upper portion nude and polished; base of legs and 

 femora with long pale hair, longer on under side; tibiee and tarsi with black
