OP PHILADELPHIA. 379 



The tip of the thorax is still more attenuated than that of the 

 huhalus Fabr. 



9. M. QUADRiviTTATA. — Thorax quadrilineate with sanguine- 

 ous. 



Inhabits Maryland. 



Body pale yellowish-green : head trifasciate with black : tho- 

 rax gibbous, with a rounded tubercle over the origin of the 

 hemelytra ; four sanguineous vittae extending near to the middle, 

 the lateral ones oblique ; four transverse black spots before, and 

 a dorsal impunctured line; tip acute : hemelytra [301 ] hyaline ; 

 nervures fuscous, greenish towards the base and basal costal mar- 

 gin : tergum, segments black at base : venter black at base : 

 pectus sanguineous each side, disk with large black spots. 



Length to tip of hemelytra two-fifths of an inch. 



Several specimens occurred on the eastern shore of Maryland, 

 cast up by the waves. 



10. M. MERA. — Unarmed ; thorax fasciate with fuscous beyond 

 the middle ; tip dull sanguineous. 



Inhabits Pennsylvania. 



Body greenish : head immaculate : thorax almost regularly 

 arquated above, with a fuscous band, rather behind the middle ; 

 tip dull sanguineous : hemelytra fuscous at tip ; nervures with 

 narrow fuscous edges : feet tinged with rufous. 



Length to the tip of the hemelytra less than two-fifths of an 

 inch. 



The thorax has no angulated appearance before, but is obtusely 

 rounded before, and behind the middle, and more obtusely so 

 above. In the A-vittata the thorax declines rectilinearly from 

 near its greatest elevation to the tip without the slightest con- 

 cavity, whereas in the present species the thorax, beyond the 

 band, declines somewhat abruptly, beyond which it still declines, 

 but rectilinearly to the tip. The tip of the thorax extends as far 

 as the nervures of the hemelytra. 



11. M. MARMORATA. — Above marbled with rufous and yellow. 

 Inhabits Pennsylvania. [ 302 ] 

 Head rufous with yellow spots : thorax regularly arquated 



above, behind the middle the line of curvature is a little con- 

 cave ; tip nearly as long as the nervures of the hemelytra : 

 1831.]
