SAY’S HETEROPTEBOUS HEMIPTERA. 
Quite distinct from the interrupta and alternata, Nob. which 
are both minutely rugulous. 
2. C, abdominalis, Abdomen sanguineous at base. 
Inhab. Mexico. 
Body blackish, with slender, yellowish transverse lines : head 
greenish-yellow, with a broad dusky line each side of the mid¬ 
dle, not extending to the orbit and hardly reaching the vertex, 
but dilated over the mouth: thorax with twelve to sixteen linea- 
tions: hemelytra minutely wrinkled longitudinally; transverse 
lineations not larger on the inner margin; lateral groove pale 
fulvous, particularly towards the base where it is hooked, and 
On the middle it has an oblique black spot: tergum at base 
sanguineous: pectus and postpectus black : feet yellowish; ante¬ 
rior pair black at tip : intermediate pair black on the tibiae and 
the tip of the thighs; posterior pair, tibiae and tip of the tarsi 
black : venter at base sanguineous. 
Length two-fifths of an inch. 
This was found in Mexico by Wm. Bennett and sent me by 
Mr. Maclure. In point of size it resembles interrupta, Nob. 
which however is but obsoletely wrinkled at the base of the 
hemelytra, its transverse lineations are much more undulated, 
and the abdomen is pale yellowish beneath; the feet also are 
immaculate. 
3. C. mercenaria , with the line snbequal and an immaculate 
space at base. 
Inhab. Mexico. 
Body smooth, pale yellowish ; head immaculate, convex before 
and with an obsolete carina, and a few punctures: thorax with 
about eight or nine transverse black lines: hemelytra with 
numerous, equally slender, transverse somewhat confused, black 
lines; a large immaculate space at base; channel of the exte¬ 
rior margin interrupted, immaculate, excepting a dusky dot at 
tip and a less obvious one beyond the middle; tip rounded: 
venter blackish, lateral margin and posterior margins of the 
segments whitish. 
Length one-fifth of an inch. 
On comparison with the alternata , Nob. it may be distinguished 
by the equality of the lineations of the hemelytra, those of that
