1922] Bibliographical Notice on the Reduviid Genus Triatoma. Ill 
forms: in T. rubrofasciata it covers 210 days, in T. megista 260 
days, and in T . infestans and T. sordida the period is intermediate 
between these two extremes. Thus there is probably but one 
brood each year. 
Many species have become “domesticated/’ and some are 
strictly confined to houses and to outbuildings about farms: 
such species are T. megista, T. sordida, T. sanguisuga, T. infestans, 
T. rubrofasciata, T. maculata, and T. rubrovaria. Neiva believes 
that this adaptation is of comparatively recent date, and 
has been acquired since the discovery of America, since, he says, 
even to-day the Indian villages are not infested with these 
insects. The primitive habitats of the species of Triatoma 
are probably nests of various mammals: thus T. geniculata 
occurs in nests of the armadillo Dasypus novemcinctus L., while 
the North American T. neotomce has been taken only in nests of 
the wood-rat Neotoma, and the South American T. brasiliensis, 
though now domesticated, is frequently found in nests of the 
rodent Cerodon rupestris Wied. The domesticated species have 
received many vernacular names, of which Neiva lists some 
twenty-five. 
The genus is then considered from the taxonomic aspect. 
Laporte’s original description is quoted in full. Then follow 
twelve pages devoted to the type species, Triatoma rubrofasciata 
(DeGeer), with quotations from Wolff, Latreille, Burmeister, 
Amyot et Serville, Blanchard, Herrich-Schaffer, Stal, and 
Walker, and with a very brief and unsatisfactory redescription of 
DeGeer’s type, which is to be found in the Stockholm Museum. 
Neiva believes that this species is a native of India, and that it 
was introduced into America and elsewhere through the medium 
of commerce. This opinion, which is diametrically opposed to 
that of Kirkaldy 1 , is based on the wide-spread distribution of 
this form in the Old World and on the fact that in America it is 
confined strictly to the coastal region. 
An annotated list of thirty-six species then follows. Pan- 
strongylus guentheri, though previously mentioned as being a 
'Can. Ent., xxxix, 1907, p. 247; Faun. Hawaii, ii, 1910, p. 550.
