116 HEMIPTERA-HOMOPTERA. 
3. Ulixes scutatus. 
Issus scutatus, Walk. Insecta Saunders., Homopt. p. 44'. 
Hab. Muxico!; Guaremana, San Gerénimo (Champion). 
In this insect the tegmina are only slightly convex and have the sides completely 
rounded, with no angulation at the shoulders; the venation is finer and closer and 
more reticulate than in U. clypeatus. 
There is a single female in our collection which I have with some doubt referred to 
U. scutatus. 
CYCLUMNA, gen. nov. 
Brevis, lata, vertice parvo, vix transverso; fronte longa, apicem versus sensim latiori, subtiliter ad medium 
carinaté; pronoto triangulari, vertice breviori; scutello pronoto sesqui-longiori ; tegminibus latis, | 
convexis, ad humeros fortiter dilatatis, vena radiali ad basim, venis ulnaribus fere ad medium, furcatis, 
pone medium transversim venosis; alis angustis, apicem tegminum attingentibus ; pedibus longis, tibiis 
posticis quadrispinosis. 
Short, broad, and convex, subglobular, with the vertex small, scarcely transverse, about as broad as one of 
the eyes, which are large ; forehead long, much longer than broad, gradually broader towards the apex, 
where it is slightly narrowed, central carina fine, but distinct, clypeus short; pronotum short, 
produced triangularly between the eyes ; scutellum about one and a half times as long as the pronotum ; 
' tegmina broad and convex, strongly dilated at the shoulders, with the radial vein forked at the base and 
both the ulnar veins at about the middle, the surface behind the middle also venose transversely ; legs 
long, posterior tibiee quadrispinose. 
This seems to be a very distinct genus, and is curious as corresponding to Picumna 
in the section with large and folded wings, the correlation of the quadrispinose hind 
tibie and the distinct furcation of the three principal veins of the tegmina being 
especially noticeable. 
1. Cyclumna subrotundata, sp.n. (Tab. XII. figg. 5, 5 a.)

marginibus segmentorum albidis; pedibus fons, dilute testaceis, fusco variegatis, spinis tibiarum 
posticarum nigris. : 
Femina segmento ultimo ventrali ad medium producto, processu anali longo, testaceo, apice obtuso fusco, stylo 
anali sat longo. 
Black, with the front-parts marked with testaceous; tegmina black, with a spot at the shoulders, an 
irregular broad band at the middle, and the apex whitish, the m. tian band towards the suture and part 
of the apex spotted with black ; legs long, testaceous, variegated with fuscous, spines of the posterior
