ANCYLOCERA.—STENYGRA. 69 
minute appendage or false joint at the end. In support of this specific difference it is 
to be noted that the outer edge of the apical truncature of the elytra forms a more 
distinct angle, and the femora are less abruptly clavate. The elytra, too, are relatively 
shorter, and their punctures larger and more separate. 
2. Ancylocera sallei. 
Ancylocera Sallei, Buquet, Arch. Entom. i. p. 832". 
Hab. Mexico (Sallé +). 
Distinguished (infer alia) by the brown sutural streak of the elytra. 
CHAMPIONA, nov. gen. 
Corpus fere cylindricum, angustum. Caput parvum, antice verticale, inter antennas modice elevatum lineaque 
centrali profunde impressum. Oculi fere divisi, lobo superiore parvo. Palpi brevissimi, apice modice secu- 
riformes. Thorax elongatus, inermis, transverse plicatus. Elytra apice utrinque bispinosa. Prosternum 
inter pedes angustum. Acetabula intermedia clausa. Metasterni episterna angusta, subparallela. Abdomen 
normale. Pedes elongati, graciles; femora versus apicem modice clavata; tibiee carinate; tarsi sub- 
breves. Antenne (¢?) corpore paullo longiores, filiformes, articulis 3°-6™ apice unispinosis, scapo sub- 
grosso, mox a basi dilatato, articulo 8° quam cexteri multo longiore, 4° quam sequente breviore, 11° 
quam precedens longiore, curvato. 
A new genus is necessary for the reception of an extraordinary and beautiful little 
Longicorn, of which Mr. Champion has recently sent home a specimen. Although 
wanting most of the obvious characters of Ancylocera, I think there can be no doubt 
its affinities lie close in the direction of that genus. The vertical forehead (though 
decidedly longer in Championa), general form of the head, the elongate, unarmed 
thorax, the large but not inelegant sculpture of the upper surface of the body, and the 
general shape of the legs, all remind one of Ancylocera; but a stronger indication of 
affinity still is afforded by the curved tips of the antenne. 
1. Championa aurata. 
Gracilis, cylindrica, late viridi-aurata nitida, sparsim breviter cinereo-setosa, elytris fasciola angusta cinerea 
paullo ante apicem; capite rugoso-punctato; thorace omnino transversim phicato ; elytris crebre, grosse, 
versus apicem subconfluenter punctatis, apice utringue bispinosis. 
Tong. 54 lin. (?). 
Hab. Guarmmana, Calderas (Champion). 
The whole insect is of a bright brassy-green colour, glowing on the head and thorax 
with a golden or red-golden hue. The ashy pubescence is very long and somewhat 
dense on the legs, antenne, and under surface of the body, but it-does not obscure 
the bright ground-colour.
