Barber — Eusuris and Neosuris 
85 
not quite reaching base of head. Pronotum somewhat 
longer than wide ; lateral margins neither carinate nor 
impressed beneath; constriction between the two lobes 
shallow; anterior lobe but little wider than head across 
the eyes ; posterior lobe not depressed, much shorter and 
subequally as wide as anterior lobe ; anterior margin 
straight; posterior margin very slightly concavely arcu- 
ate. Scutellum flat, but little wider than long. Corium 
and clavus connate, in the same plane, the latter with 
three rows of punctures ; corium very finely pilose, pos- 
terior margin straight, devoid of a membrane. The two 
trichobothria of the third visible ventral segment widely 
separated. Anterior femora strongly incrassate, with 
very few small spines beneath. Anterior tibia curved, 
finely serrate within. Pterygo-dimorphic. 
Type: Neosuris castanea Barber. 
The genus Neosuris was never adequately described. 
The character of the genus was indicated in the descrip- 
tion of the brachypterous form of what at the time I 
mistakenly placed in Stal’s genus. Not until 1918 was the 
macropterous form from the same locality recognized. 
Macropterous form : Color fusco-castaneous, anterior 
and posterior margins of the pronotum and the clavus 
paler. Character of the head and antennae as in the 
brachypterous form. Ocelli present, situated close to 
the eyes. Pronotum over one third wider than long, 
the constriction between the two lobes shallow; anterior 
lobe just over twice as long and about one fourth narrower 
than the posterior lobe ; anterior margin straight ; pos- 
terior margin very gently concavely arcuate ; lateral 
margins neither carinate nor narrowly impressed be- 
neath ;■ anterior lobe finely closely punctate ; posterior lobe 
more sparsely and coarsely punctate ; narrow posterior 
margin impunctate. Scutellum one fifth wider than long, 
rather closely punctate, faintly carinate towards apex. 
Commissure one fourth shorter than the scutellum. 
Clavus with three regular rows of punctures. Corium 
sparsely, finely pilose, rather closely and coarsely punc- 
tate. Membrane hyaline, extended to apex of the ab- 
domen. Venter finely pilose. Length 2.70 mm.
