328 MANDIBULATA. — COLEOFTEB.A. 



The following table, partly taken from Manncrheim, will perhaps 

 enable the reader to ascertain the British genera : —

Genus DXXXVIII. — Ev.esthetus, Gravenhorst. 



Antenna situated before the eyes and placed in a lateral fovea approximating 

 thereto ; rather longer than the head^ the basal joint longest, clavate, second 

 short, third longer obconic, five following minute, subglobose-moniliform, 

 the two next thickened, transverse, and with the last, which is stouter, 

 ovate-subacuminated, forming a club. Palpi unequal ; maxillary elongate, 

 three-jointed, the third joint thickened and ovate: mandibles elongate, very 

 s'ender, falcate, simple : head triangular-orbiculate, large : eyes globose, 

 very prominent : thorax obcordate : body linear, convex : legs moderate ; 

 femora slightly clavate ; tibiw simple j tarsi five-jointed. 



This curious genus, from the beauty of its antennae and its elon- 

 gated maxillary palpi, as well as from its cylindric, convex, form, 

 sculptured thorax, &c. appears rather to belong to the preceding 

 family, but the five-jointed tarsi and its general habit appear to point 

 out the present as its proper location : — one species only is known, 

 which is found in fungi, and also beneath the bark of trees.
