Ovipositor ensiform, curved upwards, compressed, acute. Legs very 
short, moderately stout; the anterior and middle tibiae slightly incurved

terior tibiae with distant very short spines each side behind. Tarsi

This insect is found near Baltimore upon Oak trees. It appears in 
the larva state as early as the first of August and can be met with fully 
developed, from the latter part of September until some time in Octo¬

Entomological Society of Philadelphia. 
It seems to form a connecting link between the Rhapidophoroid 
forms of the family and the true green Locustina. Possessing much 
of the structure of head and tarsi, and form and position of the antennae 
and eyes as in some species of the genus Phylloptera. The eyes are 
not directly in front, approaching, as in some CeutJiopMU^ they are 
much longer than broad and placed, not above, but outside of the an¬ 
tennae, the first joint of which is almost of the same breadth; the third 
joint of the maxillary palpi is as long as the fourth, and the fourth is 
but very little enlarged at tip. The reduced size of the movso- and
