Hcteropterous Hemiptera. 23 



current sublateral ventral vitta, an oblong median spot to tlie sixth 

 segment, and spots to the female genital lobes dark fuscous; 

 antennae fuscous, irrorations to upper side of first joint and a 

 rather narrow basal annulation to third joint ochraceous (fourth 

 joint wanting); rostrum and legs ochraceous, last joint of the 

 former black, numerous small round spots to femora mostly ar- 

 ranged in rows, and tibiae, except a median annulation, fuscous 

 (hind legs wanting). Head one-fourth longer than broad and sub- 

 equal in length to the pronotum in the middle, clypeus conspicu- 

 ously surpassing apex of juga, first joint of antennae as long as 

 antoocular part of head and passing its apex by about half its 

 length, second joint more tlian twice the length of first, cylindrical, 

 not at all incrassated in its basal part, third joint above one- 

 third shorter than second, rostrum reaching middle of fifth ventral 

 segment, second joint longer than third and fourth taken together. 

 Pronotum with the lateral margins slightly sinuate in the middle, 

 serrulate in their anterior half, the short humeral spines directed 

 outwards. ScutoUum with a foveolate impression in the basal 

 angles. Hemelytra passing apex of abdomen by about one-third 

 the length of the membrane. Abdomen beneath deeply grooved 

 from its base to the apex of the fifth segment. Length (excl. mem- 

 brane), ? 19 mm.

The antennae are incomplete in the type, but from the great 

 length of the second joint there can be little doubt that they are 

 four-jointed. The species is related to E. armafvs, Fabr., but is at 

 once distinguished by the structure of the antennae. It is not 

 impossible that E. calidns, Stal (nee Walk.) belongs to homi.

This species, Avhich is known to me also from West Australia, is 

 easily recognised from the good description, but it is not allied tO' 

 E. vittii'entris, Stal, as Distant says, belonging in fact to another 

 group of the genus and coming very near E. fiiscescens, StaL 

 The second antennal joint is somewhat variable in length, l^eing 

 sometimes, as in Distant's type, little more than one-third the 

 length of the first joint, but usually at least one-half its length; the
