in constant vibration, they may on that account more readily 
simulate the “antennal language" of the host insects. This, 
however, would be the result, not the cause, of the symmetrical 
clipping. 
6. Judging from the stumps which remain, the antenna of 
Attaphila differ considerably in structure from those of other 
Blattidae known to me. The joints are relatively much larger 
and longer, and therefore of a more generalized or embryonic 
type than those seen in the nymphs and adults of other species. 
Can this somewhat hypertrophied condition be the result of the 
continual clipping to which these organs are subjected? 
7. The structure of its antenne suggests that a more 
extended comparison of Attaphila with other Blattidae may 
assign it a peculiar, if not unique, taxonomic position. On 
this matter my limited acquaintance with the insects of this 
family hardly qualifies me to write. 
. The following is a more detailed description of the myrme- 
cophile that is the subject of the foregoing general remarks. 
ATTAPHILA FUNGICOLA, NOV. GEN. ET NOV. SP. 
Male (Fig. 3). — Length, 3-3.5 mm. Color: amber yel- 
low ; antennz, tibiz, tarsi, pleurze, tegmina, and overlapping 
portions of terga and sterna of the thoracic and abdominal 
segments more brownish. Body about twice as long as broad, 
glabrous, covered with rather evenly distributed short, yellow- 
ish hairs. Head scarcely projecting beyond the anterior margin 
of the pronotum, so that only its posterior edge is visible when 
the insect is seen from above. Epicranium and front broad, 
smooth, without any traces of the A-shaped suture and fenes- 
tre. — Labrum not bilobed, but obtusely pointed, extending à 
little beyond the acute, tridentate mandibles. Labial palpi 
scarcely half as robust as the maxillary palpi. Eyes very 
small, with irregular orbits, occupying the extreme lateral 
portions of the head and separated by a considerable dis- 
tance from the antennal fovea. Antennz incomplete in all 
the specimens, both nymphs and adults; first joint rather 
stout, somewhat longer than the second to fifth joints taken
