M. Boucard appears to have been the first collector to notice this species, and a male 
from one of his collections obtained at Acatepec in the Mexican State of Oaxaca, now 
in the British Museum, was described by Mr. Sclater in 18581. The same traveller 
afterwards obtained examples of both sexes at Playa Vicente?. The female, in the 
meantime, had been found by Leyland at Omoa, and was described by Mr. Sclater in 
1859 5 *, 
Shortly after this we obtained many specimens of both sexes from the hot forest 
country of Vera Paz, where and at Yzabal F. dowcardi has alone been found in 
Guatemala. 
Southwards of Guatemala this bird occurs in some abundance as far as the Isthmus 
of Darien. This appears to be the extreme limit of its range, for in the Colombian 
State of Antioquia and in Western Ecuador F. consobrina takes its place. 
Leyland says of this bird that it is solitary in its habits and is found in thickets?. 
Mr. Nutting, on the other hand, observes that it seems to be truly gregarious, and is 
usually seen in flocks of ten or a dozen 14. He adds that, in marked contrast to all the 
others of its family, these birds seem to keep to the trees at a considerable distance 
from the ground, the Formicariide in general being never seen much above the earth. 
Mr. Wood observed F. doucardi in abundance at the camp in the cordillera on the Rio 
Truando. It frequented high trees, and was never seen to descend to the bushes ?°. 
2. Formicivora virgata. 
Formicivora virgata, Lawr. Ibis, 1863, p.182'; Ann. Lyc. N. Y. viii. p.6’. 
? Formicivora boucardi, Salv. tbis, 1872, p. 318°. 
F. boucardi similis, sed pectore striolis celatis albis forsan distinguenda. Femina ut dicitur quoque differt. 
Hab. Nicaragua, Chontales (Belt *); Panama, Lion Hill (1Z‘Leannan 1 ?). 
We do not feel very confident that this bird is really distinct from /’. dowcardi, as the 
chief if not the only character possessed by the male, viz. the concealed white streaks 
on the breast, does not seem of much importance in view of the fact that /. virgata is 
found in the country where /. boucardi is common. Our specimen from Chontales 
possesses white streaks on the sides of the breast; they are, however, not shaft-streaks, 
but white edges to the feathers on each side near the base. 
* In his ‘ Catalogue of American Birds,’ p. 183, and in the recently published ‘Catalogue of Birds in the 
British Museum,’ xv. p. 255, Mr. Sclater names a male and female from “ Oaxaca” as the types of F. boucardi ; 
but this cannot be correct, as the male was first described from the Acatepec specimen now in the British 
Museum, and acquired in 1858 from M. Sallé. The type of the female described from Leyland’s specimen 
is doubtless in the Derby Museum at Liverpool.
