548 PSYCHE.
[November 1893.
located a few hundred yards to the
south at the base of the north slope of
the wooded hills. The scutellerid was
very numerous on the Nicotiana, and
lives on the juices of the plant. About
thirty adults were taken, but only one
larva. This was the only larva seen at
this date, but hundreds of the adults
could have been collected. Some ants
were observed, which appeared to
linger about the scutellerids.
Specimens of the latter were sent to
Mr. Uhler and Dr. Riley, and deter-
mined by them as Corimelaena extensa
Uhi. This record is of interest as
noting a scutellerid which affects
Nicotiana. I know of no previous
mention of a member of this family of
insects living upon this plant.
The adult of C. extema is shining
black, with the hemelytra widely,
almost wholly creamy on the sides.
The larva is very similarly colored,
being also black with a patch of
creamy on the sides of body, the hem-
elytra being not yet developed. It may
be more definitely described as follows : Larva of Corimelaena esfensa.- Length,
14 mm. ; width, I mm. Body clothed some- what sparsely with short pubescence. Head triangular in outline from above, narrower than thorax, shining black above and below, the usually invisible membranous neck-like portion which attaches the head to the thorax 'being pale or light colored. Eyes brownish. Antennae pale-colored, pubescent, 4-jointed, last joint longest and stoutest, three basal joints nearly same length and size. Beak elongate, reaching beneath body as far back as origin of hind pair of legs, pale colored, 3-jointed, basal joint a little the longest, last two joints nearly the same length, the second joint a little stouter than the last. Thorax about one-third broader than head, shining black above and below. Legs pale colored, except femora which are mostly darker. Ab- domen as wide as thorax, rounded behind, vaulted and convex, cistudinate (in the dried specimen), exposed and bare, widely shining black on the median portion longitudinally, narrowly so on the lateral edges, between the two with a lateral longitudinal stripe of creamy whitish which gradually narrows to a point posteriorly. Ventral surface
of abdomen very concave, and showing
same coloring. Scutellum and wings
wholly undeveloped.
One specimen, July 6, on Nicotiana.
Arizona.
In the adult the last joint of antennae
is no longer nor larger than the preced- ing two joints, to each of which it is
nearly equal. The legs are almost
wholly blackish or brownish, except
the tarsi and tips of tibiae. The beak
is brownish and ^-jointed, antennae
pale. Whole upper surface of head,
thorax and scutellum is dark metallic
green. Wing covers are extremely
narrow, creamy except a narrow dark
green line on inner edge which
broadens at base.
