HETEROPTEROUS HEMIPTERA. 327 



Length three-fiftlis of an inch. 



Resembles halteatus Linn. But according to Drury's figure, 

 that species has simple posterior tibiae. It is still more like L. 

 phyllopus Linn., which, however, has the white line undulated 

 and oblique, as figured by Stoll, the posterior thighs more elon- 

 gated and the posterior tibiae still more dilated, particularly on 

 the inner side, than this species. 



It is common in Florida. The male has but two denticula- 

 tions on the dilated edge of the posterior tibiae, whilst the female 

 has three ; the sinuations of the edge correspond with the num- 

 ber of teeth. 



3. A. OPPOSITUS. — Reddish-brown ; hemelytra with a white 

 point in the middle of the corium ; antennae rufous ; head tri- 

 lineated ; posterior tibiae dilated and sinuated. 



Inhabits Indiana. [ 772 ] 



This is very closely allied to ulhicinctus nob., but is uniform 



in its difierential characters. It may be known by the small 



white point of the hemelytra. 



4. A. DECLivis nob. (Rhmuchus Kirby) New Sp. N. Am. Ins. 

 found by Jos. Barabino, p. 10. [Ante, p. 305.] Thorax dilated at 

 the posterior angles ; beneath whitish sericeous ; posterior tibiae 

 dilated and compressed their whole length, more prominent 

 towards the exterior base. 



Inhabits Georgia and Louisiana. 

 Length one inch and one-fifth. 



5. A. NASULUS nob. ( " ) ibid. p. 10. [Ante, p. 305.] 



Thorax, lateral angles more or less prominent; posterior tibiae 

 dilated and compressed all their length; inner edge minutely 

 denticulate ; exterior edge a little undulated ; width decreasing 

 to the tip. 



Inhabits Georgia, Florida, Louisiana. 



Length one inch. 



This genus seems to include Pctalopus and Rhmuchus Kirby, of 

 which, however, I have not seen the characters stated, which alone 

 can establish a generic name.
