or tribe must bear the name of the typical genus the same as a 

 subgenus, including the typical species of the genus must bear 

 the name of the genus. The second tribe was called Reduviida 

 by Stal, but has been properly designated as Zelini by Bergroth 

 and others. 



Genus Ectrichodia Lep. & Serv. — Kirkaldy (Entomologist, 

 XXXIII, p. 239, 1900) goes into an elaborate explanation of why 

 he names Reduvius cruciatus Lep. & Serv. as type of Ectrichodia, 

 all of which was quite unnecessary as Laporte had already named 

 this species^as its type (Essai, p. 7, 1832) and Brulle did the same 

 in 1835 (p. 320). This generic name must therefore replace the 

 old-world genus Physorhynchus Am. & Serv. and Ectrichodia of 

 Stal must be known as Rhiginia Stal with lateralis Lep. & Serv. 

 as type. The name of our northern cruciata Say, described as a 

 Petalocheirus, is not preoccupied by Ectrichodia cruciata Lep. & 

 Serv. and will stand as Rhiginia cruciata Say. 



Genus Nabis Latr. — This genus was founded by Latreille in 

 1802 with two species mentioned, guttula and vagans Fabr., the 

 latter a synonym of j 'ems Linn. I cannot find that the former was 

 named as type until Kirkaldy did so in 1900. Vagans was named as 

 type of Nabis by Westwood in 1840, and I cannot see why this 

 type fixation is not valid. Reduvius apterus Fabr.' was named as 

 type by Latreille in 1810, Laporte in 1832, and Spinola in 1837, but 

 is invalid as apterus is not an original species. Latreille in 1804 

 and 1807 named apetrus ( = subapterus) and guttula as examples, 

 but this cannot be considered as a proper type fixation for guttula. 

 Nabis then = Coriscus Auct., = Reduviolus Kirby, with type vagans 

 =ferus Linn. Prostemma Lap. = Nabis Stal, 1873, and Reuter, 

 1908 and 1909, type guttula Fabr. 



Genus Cimex Linn. — This generic name is now so universally 

 used for the "bed-bug" that it seems unnecessary to notice it here 

 further than to draw attention to the fact that Kirkaldy's very 

 positive statements that Cimex was not and could never be 

 available for lectularius were founded on a careless and imperfect 

 knowledge of the bibliography of this genus and species. Briinnich 

 restricted genus Cimex to lectularius eleven years before Fabricius 

 founded genus Acanthia and restricted Cimex to the Pentatomidce,
