Testaceous ; head, outer apical angle of elytra and a ring on the 

 abdomen piceous ; thorax with the disc piceo-rufous ; antennae 

 long, the intermediate joints as long as broad; thorax with two 

 discoidal rows of punctures, those near the fore and hind parts 

 distinct, the intermediate punctures obsolete ; elytra nearly smooth, 

 having but extremely fine scattered punctures. 



Male with the terminal segments of the abdomen smooth and 

 glossy ; the 6th segment with a slightly raised semicircular area : 

 the 7th segment strongly emarginate at the apex, the emarginated 

 part bounded by two processes which converge slightly at the 

 apex, are moderately stout, and by no means acute : within the 

 emargination are two very minute teeth, dividing the space into 

 three equal parts. 



Female with the terminal segments distinctly punctured. 



From all other British species of Gyrophcena, excepting G. 

 affinis, the present insect is readily distinguished by its long 

 antennae, the intermediate joints (5th to 10th inclusive) being 

 fully as long as broad ; the 5th, indeed, is distinctly longer than 

 broad : they are entirely testaceous. From G. affinis it is dis* 

 tinguished by the following points : the general colouring is paler 

 (i. e. pale testaceous, instead of brownish), the surface of the body 

 is less distinctly alutaceous, and consequently more glossy : both 

 thorax and elytra are relatively longer, aud the punctures on the 

 elytra are much finer. Head rather depressed, with distinct, 

 scattered punctures. Thorax rather broader than Ipng ; somewhat 

 contracted behind ; the sides but little rounded ; the posterior 

 angles rounded ; the anterior, obtusely angled ; of the discoidal 

 punctures, usually four, on the posterior part of the thorax, are 

 distinct ; two on the fore part are less distinct, and the remainder 

 are obsolete : elytra taken together rather broader than long (not 

 distinctly transverse as in G. affinis) the surface very finely and in- 

 distinctly punctured, sometimes with the pitchy-black at the apex 

 extending across in the form of a band ; sometimes confined to 

 the outer angle^ and occasionally obsolete. Abdomen with the 

 basal segments sparingly punctured, the 5th segment usually more 

 or less piceous, the terminal segments, in the iemale, pretty thickly 

 punctured ; in the male smooth — here the 6th segment has a 

 mesial semicircular glossy area, the hinder part with the convex 

 outline, near the apex of the segment, and slightly raised ; the fore
