Peixe Boi, east of Para, Para. November to December, 1907. 
(H. B. IMerrill.) Two males, four females, six immature speci- 
mens. 
Para, Para. (W. M. Mann.) Three males, two females. 
(C. F. Baker.) Five males, three females. 
Manaos, Amazonas. (Mann and Baker.) One male. 
Porto Velho, Rio Madeira. (Mann and Baker.) One female. 
This series shows the great degree of variation in size and 
coloration so characteristic of this species. The most striking 
color feature seen in this series, aside from the shining blackish 
or dark brownish of the face and the lateral lobes of the pronotum, 
is the coloring of the dorsal surface of the head, pronotum and 
dorsal surface of the caudal femora with dull zinc orange. This 
condition is found in tw'o males and one female from Para. One 
Para male and one female from the same locality are quite uni- 
formly blackish. Two of the Peixe Boi females are more uni- 
formly mummy brown than the average from that or the other 
localities. The size variation in the Peixe Boi series is as decided 
as in the remainder of the above recorded representation. 
Paroecanthus roosevelti new species (Plate III, figs. 22, 23, 24, 25 and 20.) 
This is a very distinct species of the genus, forming with another 
at present undescribed species, and probably" F. picipes Bruner, 
a readily recognized section of the genus. The present insect 
needs no detailed comparison with the previously known species 
excepting picipes, as its distinctive livery — 'the dorsum of the head 
and pronotum being rufescent, the postocular region of the head, 
the lateral lobes of the pronotum, a spot at the base of the tegmina 
and all of the limbs, aside from the pale buffy proximal section of 
the median femora and the similarly colored ventro-proximal
