354 HETEROPTEROUS HEMIPTERA. 



8. A. EMARGINATUS. — Thorax obtusely emarginate before the 

 middle, edge without elevated lines behind. 



Inhabits Mexico. 



Body black : head with an acute tubercle at base of the 

 antennae, and another behind the eye : antennae, first joint more 

 robust than the others, rather suddenly attenuated at base, some- 

 what larger than the apical prominence of the head ; second 

 joint shorter than the first, and not longer than the last ; third 

 joint longest; terminal joint attenuated at base, pale at tip: 

 thorax transversely impressed in the middle, the impression 

 terminating each side in an obtuse emargination, edge very 

 minutely crenate ; anterior margin slightly quadrilobate ; heme- 

 lytra [ 799 ] at the termination obliquely rectilinear ; corium but 

 little longer than the scutel. 



Length nearly three-tenths of an inch. 



The thorax has no appearance of elevated lines, but these are 

 substituted by four slightly elevated obtuse bullae on the anterior 

 margin. This species is closely allied to gramdatus nob., but is 

 a much larger insect. 



9. [A.] LOBATUs. — Thorax acutely emarginate before the mid- 

 dle of the edge, without elevated lines behind. 



Inhabits Indiana. 



Body fuscous, granulated : head with the projection before the 

 eyes rather obtuse, tip robust, obtuse ; antennae, third joint longer 

 than the second : thorax quadrilineate before the middle ; lateral 

 edge acutely emarginate before the middle, anterior angles lobi- 

 form : scutel with an elevated line and lateral edge : hemelytra 

 with a short corium ; much narrower than the tergum : rostrum 

 not longer than the head. 



Length seven-twentieths of an inch. 



Resembles gramdatus and emarginatus nob., but the nasus and 

 angulated projection before the eye are much more obtuse, and 

 the emargination of the lateral edge of the thorax is acute and 

 more profound, and the thoracic liueations are in much higher 

 relief. The species is uncommon. 



ANEURUS Curtis. 



A. POLiTUS. — Rufous ; tubercle before the eyes short obtuse. 

 Inhabits Florida.
