Cavinas , Beni , Bolivia ( Type locality ) ; Tumiipasa .

Host. — Eciton legionis F . Smith subsp . crenulatum Mann .

Type and Allotype . — ^{Cat . No. 26483 U. S . N . M .}

This species differs from N . ruja Kieff . , described from Mar -

capata

, Peru, with no

note to

indicate myrmecophilous habit , in the entire absence of wings . Kieffer had before him only speci -

mens with elongate peti

^'

ole which he considered females , and I am following him in this .

One specimen was taken from each of

two

colonies and

twenty

of both sexes from a third . Like the following species , N . cor -

nuta

runs in the

ant

column , apparently in frantic haste , and I did

^not

observe the

ants

pay any attention

to

it . One may assume that both are parasitic

^on

the

ant

larvae .

Mimopria ecitophila Holmgren

.

Rio Beni, Bolivia . Rurrembaque , Little Rio Negro , Cavinas , Cachuela Esperanza .

Host. — Eciton hamatum Linn .

This seems

to

be usual in the files of

hamatum

, never abundant in a single column , but

to

be found in nearly

every

one examined .

It has now been recorded from Peru , Bolivia and Brazil and probably extends throughout the ^range of its host .
