part gradually descends to the same plane as the rest of the seg- 

 ment : the 7th segment has the lateral processes, which bound the 

 emaro-ination, rather shorter and stouter than usual. 



I have seen but four specimens of this species, three in Dr. 

 Power's collection ; and one individual taken by Mr. Rye in 

 funo-us at Coomb Wood. This latter specimen presents but one 

 minute tooth in the emarginated part of the 7th abdominal seg- 

 ment of the male, and the pitchy-black of the elytra and 5th ab- 

 dominal segment is scarcely traceable, so that the insect appears 

 almost entirely testaceous with the exception of the head ; in 

 other respects it does not appear to differ from Dr. Power's 

 specimens.

Pitchy testaceous ; head, thorax, posterior angles of elytra, and 

 ante-penultimate segments of abdomen pitchy ; legs and antennae 

 testaceous : thorax with two dorsal rows of punctures, and a few 

 scattered punctures both at the sides and on the disc : elytra with 

 distinct but widely separated punctures : antennae relatively long. 



Male with a single small tubercle on the 6th abdominal seg- 

 ment : the 7th segment terminated by two elongated processes ; 

 these by no means widely separated, and somewhat incurved at 

 the apex. 



This species is usually rather less than G. nana, and is readily 

 distinguished from other British species (excepting G. pulchella) 

 by its comparatively long antennas — here the joints from the 5th 

 to the last are relatively large ; those nearest the base are rather 

 longer than broad, whilst the penultimate joints are nearly equal 

 in length and breadth. The head is pitchy black, and presents a 

 few scattered punctures. The thorax is rufo-piceous, less strongly 

 transverse than in G. nana, and with the sides less boldly rounded, 

 and the anterior angles slightly obtuse : the discoidal rows of 

 punctures usually contain five punctures in each row, the basal 

 pair more approximated than the second pair, which are the 

 largest, the 4th puncture in each row is usually distinct, the 3rd 

 (sometimes replaced by two punctures) does not appear to be re- 

 presented on the thorax of G. natia, and is here small ; and the 5th, 

 or apical puncture, is not unfrequently wanting or very indistinct. 

 Besides these there are several punctures on the disc (between 

 the rows of punctures) which are wanting in G, nana. Both head
