MORGAN HEBARD 26 I 



We have been fortunate in ha\'ing additional material for com- 

 parison, from places where the species arc native, of all the 

 species here considered, excepting Platyzosteria bifida and Hor- 

 metica advena. 



PSEUDOMOPINAE 

 Latiblattella species 



A female of a species of this genus, related to L. pavida (Rehn), 

 is before us. 



As the steamship Tenadores had on previous trips loaded bananas 

 only at Bocas del Toro, Panama, and Limon, Costa Rica, the 

 material found on that ship and recorded in the present paper was 

 almost certainly taken on at one of the two places.

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



Cariblatta insularis (Walker) 



1868. Blatta insularis Walker, Cat. Blatt. Br. Mus., p. loi. [ ?, Jamaica.] 



This very small insect, with head strikingly marked, delicate 

 picturing of the pronotum and two proximal darker dashes on 

 each of the elongate tegmina, is known to be native in Porto Rico, 

 Jamaica and Antigua.

Neoblattella fratercula Hebard 



1916. Neoblattella fratercula Hebard, Ent. Xews, xxvii, p. 159. [cf, 9; Isla de 

 Cocos, Costa Rica, and material listed below.] 



The present species is the smallest known of the North American 

 species of Neoblattella. It shows some affinity to N. brunneriana, 



'»8The specimen is without question ad\entivc, having probably escaped from fruit 

 in nearby stands. 



3»s The subgenilal plate of this specimen is evidently distorted and does not agree with 

 a large topotypic Jamaican series before us, which have the subgenital plate symmetrical 

 with sinistral specialized style distinctive. See Hebard, Trans. Am. Ent. Soc. xlii, p. 

 175 and p. 160, footnote 16, (1916). In the present specimen the median production of 

 the subgenital plate is distorted: the sinistral style irregularly formed, showing three 

 spines. In all other respects the specimen is normal and these features are in our opin- 

 ion best referable to decided individual abnormality.
