BRAZILIAN MUTILLA.

abdoraiual segment above are shaped much as in manca, but larger and more 

 deeply yellow, those at base shorter and not so linear; segments 2-4 have a pale 

 pubescent spot on each extreme side at apex. 



Chapada, Corumba, Santarem. This species, or manca, or sodalis, 

 or borba, or auxiliary, may prove to be identical with parallela 

 Klug ; the description of that species is not sufficiently concise t(» 

 determine with certainty. 



84. M. borba 9 .—Length 12-16 mm.— This is also very much like graphica, 

 being of same form ; but the pale pubescent stripes on the thorax are not inter- 

 rupted, and reach nearly to anterior margin of prothorax ; the tibise and tarsi 

 are densely pale pubescent; the smooth yellow spots on second abdominal seg- 

 ment above are shaped much as in graphica, although those on the posterior part 

 of the segment are larger and broader. 



Chapada. Common. The pale pubescent stripes on the thorax 

 are much as in manca, from which this species differs by the pale 

 calcaria, pale pubescence on the legs, and the transverse— not 

 oblique -yellow spots on posterior part of second segment of the 

 abdomen. 



85 1?I. jiivenalis Gerst. (Archiv. f. Naturg., xl., p. 75).- 9 .-Length 12-15 

 mm -Same form as manca, and very much like that species; but the thorax is 

 not distinctly notched at sides; the two yellow spots on posterior part of second 

 abdominal segment are transverse, not oblique; and the central silvery pubes- 

 cent stripe on apex of abdomen is formed of spots on apical middle of segments 

 3-6, while in manca it is 2 6. 



Chapada. Common. 



86 M. anxiliaris 9 .—Length 11-14 mm.— Compared with juvenalis Gerst., 

 this spec'ies has the pale pubescent stripes on thorax shorter, the legs have pale 

 pubescence, the smooth vellow spots on base of second abdominal segment above 

 are shorter ovate, and on this segment there is a small pale pubescent spot on 

 apical middle, wanting in juvenalis; otherwise the two species are much alike. 



Chapada. 



This and the seven preceding species, having the liead entirely 

 black above, closely resemble each other in the ornamentation of 

 the abdomen, and may be separated as follows : 

 Head large, broader than thorax ; no pale pubescent spot on apical middle of 



second abdominal segment "9. vivata. 



Head of usual size, not broader than thorax ; a small pale pubescent spot on 



apical middle of second segment, except in juvenalis 2. 



o Pale pubescent stripes on thorax interrupted on mesothorax posteriorly. ^ 



80. graphioa. 



Pale pubescent stripes continuous, not interrupted 3.
