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 adentivc, 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 opinion best referable to decided individual abnormality.
and also may be said to show the nearest approach, in the present genus, to the South American complex of the genus Cariblatta^^^

The present species is an aberrant member of the Impar Group of the present genus, which group includes a great number of species of medium small size, in which the sexes are but little dissimilar and the tegmina show distinct cross-veinlets, particularly distad.
^oSee Hebard, Trans. Am. Ent. Soc, .lv, p. 100, (1919).
This insect shows the nearest approach to the forms found in the closely related genus Carihlatta Hebard.^^

These specimens are appreciably larger than those of the type series, possibly due to development in a more favorable environment.
