ANNUAL REPORT OF NEW-YORK 
say’s HETEROPTEROUS remiptera. 
2. C. bilineatus Nob. 
Var. A. picea , Entirely light piceous. 
Inhab. Indiana. 
Gonocerus Lat. 
G. antennator Fabr. The author describes this species to 
have the second joint of the antennae scabrous and the “ ultimo 
claviformi.” Now if these characters are correct, a species 
in my collection, and which is not rare, is altogether new; but 
this I consider doubtful. I will however state the differential 
characters, viz : 
G. dubius, Antennae, first joint scabrous or with short spines; 
ultimate joint oblong oval. 
Length nearly half an inch. 
Inhab. Penns, and Indiana. 
It is probably the insect that naturalists refer to antennator F. 
Syroma[s]tes, Lat. 
1. S. rejlexulus, Reddish-brown ; head carinate before. 
Inhab. Pennsylvania. 
Body reddish-brown, with rather large, confluent punctures: 
head not extending more than half the length of the basal joint 
of the antenna}, obviously carinate between the antennae, tuber¬ 
cles each side of the antennae ; acute : antennae , first joint robust, 
rough, much narrowed: second joint shorter than the third; 
terminal joint half as long as the third : thorax , lateral margin 
a little reflected, the edge concavely arquated : posterior angles 
rounded; anterior angles prominent, acute: scutel narrowed 
before the tip: hemelytra, corium yellowish, rufous near the 
scutel; nervurus very distinct; lateral edge a little reflected ; 
membrane hyaline : beneath greenish-yellow ; feet palo rufous ; 
posterior thighs dilated, spinous beneath. 
Length one-fourth of an inch. 
The rostrum hardly reaches the posterior coxae. The last joint 
of the antennae is elongate-oval and much shorter than the 
preceding joint, as defined by Latreille in this genus. 
2. S. fratercuius, Anterior point of the head extending nearly 
to the tip of the first joint of the antenna}. 
Inhab. Georgia and Indiana.
