BRAZILIAN MUTILLA. 17 



with base of second segment and conforming in outline tlievewith ; apical seg- 

 ment above broad, flat, opaque, longitudinally aciculate. 



Black; occiput, cheeks, face beneath antennse and scape clothed with griseous 

 pubescence; vertex above with two ill-defined spots of pale pubescence; thorax 

 ferruginous above, margined all around with black ; legs black, with pale glitter- 

 ing pubescence, that on tibiae and tarsi golden in certain lights, calcaria whitish ; 

 abdomen with short appressed black pubescence on base and sides, mixed with 

 paler hairs; apical sides of first segment, an undulated band, slightly interrupted 

 medially, on apex of second segment, and two stripes beginning at base of second 

 segment and extending to apex of fifth segment, all of silvery pubescence, the 

 stripes on second segment subinterrupted before reaching the band at apex; ven- 

 ter black, the segments fringed at apex with long pale pubescence. 



Cliapada. One specimen taken in November. 



This species is more robust than lineola Fabr., with the thorax 

 broader, subquadrate and sides parallel, lateral margin of meta- 

 thorax serrate, the first abdominal segment broader, and second 

 segment differently ornamented. Compared with phalerata this 

 species is broader and stouter, and the thorax shorter and more 

 quadrate. 



6. .11. phalerata Klug (Nova Acta Cses. Nat. Curios., x, 308, pi. xxii, fig. 3).— 

 9- — Length 8.,") mm. — Head and thorax deeply, closely and confluently punc- 

 tured, the former subtransverse, slightly broader than thorax ; eyes rather large, 

 ovate, flattened and distinctly netted ; thorax elongate, at least twice longer than 

 broad, more or less narrowed towards the middle from both ends; metathorax 

 obliquel.v truncate, the lateral margin with several small acute teeth; pleura im- 

 punctate and pale sericeous ; abdomen ovate, as long as head and thorax com- 

 bined ; first segment broad, depressed, gradually dilated posteriorly and sessile 

 wfth base of second segment; apical segment above finely longitudinally acicu- 

 late, or alutaceous. 



Black; cheeks, occiput, face and scape of antennse clothed with rather long 

 griseous pubescence ; vertex with a very short pale golden pile, more obvious in 

 certain lights, otherwise the pubescence is fuscous: middle of mandibles, tuber- 

 cles at base of antennae and base of flagellum more or less, rufo-testaceous ; thorax 

 ferruginous, sparsely pubescent, sometimes an elongate black spot on each side of 

 raesothorax posteriorly; legs black, rather thickly clothed with pale glittering 

 pubescence, tarsi rufo-testaceous, calcaria pale; abdomen above with short ap- 

 pressed black pubescence, that on base and sides long, thin and pale ; apical mar- 

 gin of first and second segments narrowly, and two narrow stripes extending from 

 base of second segment to the apical segment, of silvery ochraceous pile, some- 

 times interrupted into spots on segments 3-5; venter piceous or rufo-piceous, the 

 segments fringed at apex with griseous pubescence. 



Chapada ; Rio de Janeiro. This seems to accord tolerably well 

 with Klug's description and figure.
