Closely allied in form and colours to an undescribed 
species from Texas. The pale brown fasciae of the elytra 
form very slender lines, the second fascia is arcuate 
towards the base, the third towards the apex, so that the 
, two together form a large ring on the apical half of the 
two elytra. The abdominal segments in the $ are dis- 
torted in a similar way to the European types of the 
genus.

(Charac. emend.) . Corpus lineare, tenue. Caput supra 
inter antennas planum, ultra oculos paulo prolongatum, 
attenuatum ; oculi distantes ; palpi breves, apice truncati ; 
antennge ( A ) corpore dimidio longiores, tenues, fili- 
formes, breviter sparsim setosae, articulo basali elongate, 
leviter incrassato, articulis 3-11 longitudine subasquali- 
bus, simplicibus . Th orax angustus, elongatus, medio paulo 
dilatatus, lateribus subtuberculatus. Elytra linearia, plana,

Cox 80 anticse globulosse, exsertge. Acetabula intermedia 
extus aperta, mesosterni epimera angusta. Abdominis 
segmenta $ normalia, prime magis elongate. 
This genus, the position of which Lacordaire considered 
doubtful, appears to belong to the group OhriincBj with 
the species of which it also agrees in facies.
