punctulatis ; antennis corpore brevioribus, crassis, dense undique

Similar in general colours to Arenica canescens (Klug), 
but differing in the pale markings of the elytra being linear, 
forming on each three elongated and oblique or curved streaks, 
and also in the remarkably thickened antenne. Although 
the scape is shorter than in the type species (1. hirticornis) , 
it bears the same relative proportion to the other joimts. The 
middle tibie are entire ; in 4. canescens, according to Klug’s 
figure, they are notched. 
Afrenica leucippe. 
Robusta, ochraceo-fulva, subtiliter tomentosa, thorace vitta dorsali 
(postice dilatata), elytris macula ante medium elongata triangu- 
lari suturali communi, altera utrinque vitteformi ante apicem 
corporeque subtus vitta laterali cretaceis; thorace elongato, 
cylindrico, postice vix angustato; elytris apice acuminatis et 
utrinque longe spinosis, dorso sparsim subgrosse punctatis (punctis 
fuscis); antennis crassis, filiformibus, pilosis ; scapo brevi, quam 
articulus tertius paullo breviore.

Airenica porosa. 
Robustior elytrisque latioribus, atro-fusca, tomento subtili cinereo- 
ochraceo vestita; thorace cylindrico, scabroso-punctato; elytris 
apice rotundatis, angulo suturali producto acuto, dorso punctis 
magnis nitidis sublineatim impressis, interstitiis (versus basin) 
punctulatis ; antennis haud pilosis, subtus sparsim breviter cilia- 
tis ; tarsis articulo unguiculari ut in &. hirticorni valde elongato, 
gracili, sed unguiculis ramo irteriore multo breviore.

Corpus cylindricum, angustum. Caput post oculos dilatatum, subtus 
haud retractum, frons brevis. Thorax cylindricus, basi angustatus 
vel constrictus. Elytra parallela, apice conjunctim rotundata, 
absque carinis lateralibus. Antenne filiformes, robuste, longe

The type of this genus is Saperda triangularis of Germar. 
It differs from the allied genera Hrana and Hssostrutha in the
