Ixxvii] @io as 
of his experience of the habits of the insect. All four were 
captured in the year 1828, and they bear labels as follows :— 
(1) “22. 1. 28. This species I have generally found in my 
bedroom, and this individual in my bed.” 
(2) “26. 5. 28. In cubiculis et in lecto ipso.” 
(3) “II 4.6.28. In lecto. Its body filled with red blood, 
sucked from the human body as the common Cimea lectularius.” 
(4) 14. 6. 28. Percebéjo paulista.” 
All these labels except the second were written by Burchell 
in Brazil during his residence at Goyaz (Nov. 3, 1827 to Aug. 
21, 1828). In the case of the second the original label had 
been replaced by another carefully written by Burchell after 
his return to England. 
The fourth label suggests a local name, which, however, 
Burchell discredited in the following paragraph in his 
Brazilian note-book. It is to be observed that the note 
refers to a specimen taken three weeks later than No. (4). 
1235. Cimex. The name Percebéjo paulista, if applicable 
to any, would be given to (. lectularivs, but this name was 
a mere extempore invention by the person who gave it 
me. The present Cimex is here commonly called Percebéjo 
cascido.” The note is undated, but the date “4.7.28” 
accompanies No. “1235” on the specimen. 
Don Fernando de Arteaga has kindly interpreted the 
Portuguese words. ‘‘ Persevejo,” as it should be spelt, means 
“bug,” while “ Paulista,” apart from various meanings derived 
from St. Paul, bears, colloquially, the figurative significance 
of “obstinate” or “pig-headed.” ‘‘Cascudo” means “with 
a thick shell,” and figuratively “of a rough exterior.” It is 
probable that the word is here used in the latter sense. 
Burchell’s specimens (2) and (3) are represented on p. 10. 
Commander Walker has directed my attention to Darwin’s 
account of another species of the same genus which he 
encountered only a few years later than Burchell, but in a 
very different part of the continent. This species, probably 
C’. infestans, Klug., was spoken of as the Benchuca. Darwin’s 
interesting record is as follows :—‘‘ At night [at Luxan, near 
Mendoza, Mch. 26, 1835] I experienced an attack (for it 
deserves no less a name) of the enchuca, a species of
