ORTHOPTERA 
BLATTIDAE 
Of the sixteen species of cockroaches now known to be in 
Hawaii, all but one, Oniscosoma pallida Brunner,?° have been 
treated below. All but two are undoubtedly adventives and these 
two may have been introduced from the islands of the southern 
Pacific, where both are found. 
Not a single species of cockroach peculiar to Hawaii exists.

Two species were originally referred to Abrodiaeta Brunner, 
modesta and latipennis, both described by Brunner. In 1895, Saus- 
sure and Zehntner proposed the name Allacta for this genus, as 
Abrodiaeta Brunner had been found to be preoccupied. The first 
type designation®® is invalid, as the species indicated, lobata of 
Saussure, was not mentioned by name in the original generic 
description. We, therefore, here select modesta (Brunner) as 
genotype of Allacta. 
Saussure and Zehntner, in 1895, considered that the genus 
included two very distinct sections, the first Oriental (and Aus- 
tralasian), the second Malagasy. In 1907, Shelford properly 
separated these as distinct generic units, describing and naming 
the Malagasy section Anallacta.?’. 
We find that Allacta belongs to an Oriental and Australasian 
phylum which at the present time is very poorly understood.
