262 NORTH AMERICAN BLATTIDAE 



and also may be said to show the nearest approach, in the present 

 genus, to the South American complex of the genus Cariblatta^^^ 



Lincoln, Nebraska, VII, 15, (in bananas, probably from Central America), i d', 

 [Hebard Cln.]. 



S. S. Tenadores, en route New York to Jamaica, X, 19, 1913, (Hebard; dead in 

 hold), 2 9, [Hebard Cln.]. 



Neoblattella detersa (Walker) 



1868. Blatta detersa Walker, Cat. Blatt. Br. Mus., p. 215. [ 9, Jamaica.] 



This plain and medium-sized species shows a remarkable and 

 distinctive specialization of the male subgenital plate. Material 

 from Hayti and Jamaica is before us. In the latter island the 

 insect is abundant. 



Green Bay, Wisconsin, VI, i, 1915, (N. F. Howard), i c^, [Hebard Cln.]. 



Neoblattella nahua (Saussure and Zehntner) 



1893. Blatta nahua Saussure and Zehntner, Biol. Cent.-Amer., Orth., i, p. 42, pi- 

 iv, figs. 19 to 21. [cf, 9 : Mexico; Atoyac, Vera Cruz, Mexico; Tabasco, Mex- 

 ico.] 



This large species is closely allied to the genotype, A^'. adspersi- 

 collis (Stal), from which species it is readily separable by excellent 

 male genitalic and other characters. The superficial resemblance 

 of the two species is remarkable. 



S. S. Tenadores, en route New York to Jamaica, X, 19, 1913, (Hebard; dead 

 in hold), I 9, [Hebard Cln.]. 



Neoblattella fraterna (Saussure and Zehntner) 



1893. Blatta fraterna Saussure and Zehntner, Biol. Cent.-Amer.. Orth., i, p. 44- 

 [cf, Chontales, Nicaragua.] 



This very broad, medium-sized species is nearest in relationship 

 to A^. nahua, of the known species of the genus, but shows very 

 great differences, not only in size and form, but also in the genitalia 

 of both sexes. 



S. S.'Tenadores, en route New York to Jamaica, X, 19, 1913, (Hebard; dead in 

 hold), I c?, [Hebard Cln.].
