CURCULIONIDiE. — KUTIDOSOMA. 45 



Cu. Ptinoides. Marsham.— Ac. Ptinoides. Steph. Catal. 157. No. 1598. 



Piceous ; with scattered cinereous scales above, and erect muricated black spinu- 

 lose ones: eyes brown: thorax deeply punctate : elytra dilated before the 

 middle, attenuated posteriorly, deeply and coarsely punctate-striate ; varie- 

 gated with cinereous; beneath rufo-piceous, densely clothed with cinereous 

 scales : legs and rostrum rufo-ferruginous : antennae pale testaceous. 



Var. B ? Ac. variegatus. Steph. Catal. 157. No. 1599.— Considerably larger than 

 var. «, with the base of the elytra variegated with ashy scales, and the apical 

 half entirely pale cinereous : in other respects similar to the preceding; but 

 the elytra appear to be more deeply striated in proportion, and the legs and 

 antennae are of a deeper hue. 



Not uncommon in sandy and gravelly places, especially in the 

 sand-pits on Hampstead-heath, and in the gravel-pits at Coombe- 

 wood: also found at Darenth, Ripley, Flertford, in Devon, &c. 

 " Not common (near Swansea).''— L. W. DUhvijn, Esq. 



Genus CCLXXXVIIL— Rutidosoma* mihL 



AntenncB geniculated, 12-jointed, rather short and stout : funiculus 7-jointed, 

 the two basal joints elongate : the remainder nodose ; club large, acuminated. 

 Rostrum rather long, stout, considerably bent, inserted during repose in a 

 pectoral groove, which extends to the base of the intermediate legs : head 

 rounded, inserted up to the er/es, which are globose, in the thorax ; the latter 

 short, narrowed anteriorly, with the sides rounded, the base bisinuated: 

 scutellum obsolete : elytra globose, moveable : legs rather long, stout ; femora 

 clavate, each furnished with a minute tooth ; tibia; with the apex truncate, 

 armed with a hook. 



This genus differs from Acalles by the dissimilar structure of 

 the antennse, the club of which is larger and acuminated ; the 

 form of the rostrum, which is longer and more bent; the short 

 thorax; the free motion of the elytra; the elongated legs, dentate 

 femora, &c. : by most of which characters it also disagrees with 

 Ceutorhynchus and the allied genera. 



Sp. 1. globula, Niger, subopacus, lined suturali pedorisque lateribus albido- 

 squamosis, elytris prqfunde sulcatis jmnctatisque, interstitiis angustis, ere- 

 natis. (Long. corp. | — 1 lin.)
