BRAZILIAN MUTILLA. 31 



ciform mark, lower portion of flanks, three stripes on first abdominal segment, 

 continued on base of second, the central stripe shorter, forked at base and tri- 

 angular at apex, a hiarciiate band on apex of second segment, produced anteriorly 

 on disk, sides of segments 2 and 3, two dots on apical middle of second, small spot 

 on apical middle of segments 3 and 4, large spot on 5, and two hands on venter, 

 all of appressed white pubescence; abdomen elongate oval, first segment narrow, 

 gradually dilated posteriorly, and conforming in outline with base of second 

 segment, which is narrow. 



Chapada. Common. 



35. M. centrovittata. — 9. — Length 8-13 mm. — Head transvei-se, not 

 broader than thorax; eyes very convex, smooth, polished; thorax rather short, 

 laterally subcompressed, not constricted when viewed from above, gradually 

 narrowed posteriorly; metathorax rounded above; abdomen broad ovate, con- 

 vex, gibbous at base of second segment ; first segment small, narrow, flattened 

 above; pygidium finely longitudinally aciculate ; second ventral segn)ent finely 

 punctured. 



Black, velvety, with scattered long black hair, erect on head and thorax and 

 more or less decuml)ent on abdomen; head above and face densely ochraceous 

 pubescent, with longer pale hair, paler on the cheeks; a stripe of ochraceous 

 pubescence on disk of thorax its entire length, broad anteriorly, and gradually 

 narrowed to apex of metathorax ; flanks of thorax with dense pale ochraceous 

 pubescence; legs with pale pubescence, the coxse and femora with long pale hair, 

 calcaria black ; abdomen velvety black, first segment above, a large broad trans- 

 verse, slightly oblique spot on each side of apical third of second segment, and a 

 spot on disk of segments 4 and 5 above, of dense pale ochraceous pubescence; 

 apical segment above, and the venter especially at base, more or less ferruginous ; 

 apical margin of ventral segments 2 and 3 fringed with pale pubescence. 



Chapada. Common. 



36. n. Gazagiiairei Andre (Bull. Soc. Ent. France, 1S9.5, p. cccxxii). — 9- 

 — Length 8-12 mm. —Closely allied to centrovittata both in form and color, but differs 

 as follows: The head is clothed entirely with pale ochraceous pubescence, except 

 a small black spot on disk of vertex; the thorax has two rather broad, entire 

 pale ochraceous stripes above ; the ochraceous spots on second abdominal segment 

 are more widely separated on disk, and rather more oblique; the apical segments 

 are broadly pale ochraceous at sides and with long pale hair, while the venter is 

 fuscous, with long pale hair, and the apical margin of the segments fringed with 

 pale pubescence; the apical segments above have no pale spots on disk; legs 

 fuscous, with long pale hair. 



Chapada. Common. Much like eentroviitata, but easily separ- 

 ated by the thorax having two pale pubescent stripes, and by the 

 apical segments of abdomen above having no discal spots.
