1922] Bibliographical Notice o?? the Reduviid Genus Trintoma. Ill 



forms: in T. rubrofasciata it covers 210 daj's, in T. megista 260 

 days, and in T. infestaiis and T. sordida the period is intermediate 

 between these two extremes. Thus there is probably iDUt 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 probal^ly nests of various mammals: thus T. geniculata 

 occurs in nests of the armadillo Dasypus novemcinctus L., while 

 the North American T. neotoma' has been taken only in nests of 

 the wood-rat Neotoma, and the South American T. brasiJiensis, 

 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 KirkaldyS 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.. xxx'x. 1907. p. 247; Faun. Hawaii, ii, 1910. p. 550.
