1IEM1PTERA HETEROPTERA. 4 3 9 



scutellum roughly and rather thinly punctured. Thorax smooth in front ; 

 horns acute, shorter than their breadth at the base. Scutellum attenuated, 

 acute. Abdomen above black, testaceous along each side; hind angles of 

 the segments successively more elongated and acute, those of the apical 

 segment forming two stout spines. Fore wings reddish, speckled with 

 testaceous along the costa and along the hind border; a testaceous forked 

 vein in the disk; membrane cinereous, brown towards the base. Length 

 of the body 6 lines. 



The abdomen of this species has four apical spines beside the 

 exterior spines formed by the hind angles of the apical segment. There 

 are so many gradations in the length of these spines that they cannot be 

 considered as a generic character. It much resembles E. melacantha, but 

 the horns of the thorax are shorter and pale.

 punctures black. Thorax with two very irregular aud much excavated

 in front; horns acute, much shorter than their breadth at the base. 

 Scutellum acute, slightly attenuated, with three very irregular green bands, 

 the third apical. Pectus and under side of the abdomen with broad trans- 

 verse piceous streaks on each side. Hind angles of the abdominal segments 

 successively more elongated and acute, those of the apical segment forming 

 two stout black spines. Legs testaceous; femora black; anterior tarsi 

 piceous ; first joint of the hind tarsi piceous beneath. Fore wings fer- 

 ruginous-red, very thickly and minutely punctured ; costa and ramose 

 veins testaceous; membrane amcous-brown. Length of the body 10j
