HETEROPTEROUS HEMIPTERA. 323 



Inhabits United States. 



Body piceous-black : head emarginate : antennae, second joint 

 dull rufous ; ultimate two joints rather long : thorax with 

 numerous punctures, before the middle impunctured ; lateral 

 edge white : hemelytra on the lateral edge white : abdomen 

 excepting at base, with a white edge : tibiae white on the exte- 

 rior edge. 



Length about one-fifth of an inch. 



It is smaller than hilinealus nob., and larger than spinifroihs 

 nob., and very diflPcrent from either by many characters. A 

 very common species. It much resembles the hvnotatus, but is 

 destitute of the white spots of the hemelytra. [ 768 ] 



[Described also as Sehiriis albonotatus Dallas, Brit. Mus. Cat. 

 Hempt. part 1, 127. — Uhler.] 



2. C. BILINEATUS nob. 



Var. a. picea. Entirely light pic€0us.

[Belongs to Aethus Dallas.] 



GONOCERUS Lat. 



G-. ANTENNATOR Fabr. The author describes this species to

 my collection, and which is not rare, is altogether new ; but 

 this I consider doubtful. I will however state the diflFerential 

 characters, viz : 



Gr. DUBius. — Antennae, first joint scabrous or with short 

 spines J ultimate joint oblong oval. 



Length nearly half an inch. 



Inhabits Pennsylvania and Indiana. 



It is probably the insect that naturalists refer to antennator F. 



[Appears to be Coreus antennator Fabr. Syst. Rhyng. 198 : 

 it belongs to Chariesterus, and is C. moestus H. Schf 7, pi. 217, 

 fig. 681.— Uhler.]
