HEMIPTERA HETEROPTERA. 439 
scutellam 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 angeles of 
the segments successively more elongated and acute, those of the apical 
segment forming two stout spines. Fore wings reddish, speckled with 
lestaceous 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 genetic character. It much resembles £. melacantha, but 
the borns of the thorax are shorter and pale.

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 eneous-brown. Length of the body 102
