infmnated, nervures stout, and, together with the stigma and para- 

 stigma, blackish ; squamulse black; radial areolet short, broad, as 

 large as the stigma ; 3d abscissa slightly bisinuated, convex out- 

 wardly near the apex ; radius of hind wings somewhat curved 

 near the base, radial areolet narrowly lanceolate. Body dull, 

 elongate, minutely rugulose. Head finely shagreened, striolated 

 round the orbits ; cheeks much dilated, so that the head seen from 

 above is widest behmd the eyes ; face thinly beset with whitish 

 hairs ; frontal fovea large, shallow, smooth in front, striolated 

 behind, geminated. Antennae 25-jointed, as long as the body, and 

 much longer than those of C. sulcatus, Nees, sp. 15, $ . Prothorax 

 unusually produced, forming a distinct neck, somewhat shining, 

 striolated. Mesothorax thickly punctulate, variolose with larger 

 punctures before the scutellum, which is also punctulate and not 

 margined. Metathorax finely reticulated, transverse, truncate, not 

 denticulated. Abdomen as long as the head and thorax, sculptured 

 as usual, with 2 inchoate carinas among the basal striae, narrowest 

 at the base, and increasing in width to the obtuse apex, beneath 

 which is an oblong transverse fissure with a small angular pro- 

 jection on its upper edge, and ciliated with whitish hairs. ^ . 

 Length, 1^ ; wings, 2f lin. 



The elongate form, produced prothorax, shape of the 

 head, and length of the antennae, distinguish this from 

 sulcatus, Nees, latrnnculus, n. s., and ixircicornis, Schaff. 

 It belongs to Thomson's last section, with cubical head, 

 immarginate scutellum, &c., but apparently not to any 

 of his species. 



I found one male in an osier-ground at Nunton, near 

 Salisbury.
