2. — SECTION, PENULTIMATE JOINT OF TAESI BILOBED, 



A. Abdomen margined. 



BINOTATUS, Ljungh, Mriclison. 2i lin. Elongate, flattish, dull 

 black, very thickly clothed with short silvery pubescence. Antennae 

 short, pitchy-red, the basal joint and club pitchy. Palpi pitchy, with 

 the basal joint testaceous. Head narrow, and flat in front. Thorax 

 nearly cylindrical, contracted behind, closely and moderately strongly 

 punctured, with a broad oblique depression on each side behind the 

 middle. Elytra a third longer than the thorax, rather more strongly 

 punctured, the interstices flat, with an obsolete broad depression on 

 each side, strongest near the hinder margin. Each segment of the 

 abdomen is slightly contracted near the base, and the transverse grooves 

 are represented by a slight ridge, the keels being obsolete. 



In the male the sixth segment beneath has a deep triangular notch, 

 and the second, third, and fourth segments are slightly depressed in the 

 middle of the hinder margin. 



Northumb., Durham, Cumb., Falkirk, Boston, Wicken and Hor- 

 ning Eens, Brighton, Bungay, Eepton, and London district. Common. 



PUBESCENS, (Kii'hy) Stephens. 

 subimpressus, Erichson. 



Similar to the preceding, but larger, more robust, and with the 

 legs stouter, the antennae longer and lighter, the palpi rather more 

 testaceous at the base of the joints, the head and thorax wider, the 

 elytra longer, and the punctuation finer and not so close. 



In the male the sixth segment has a broad, deep, somewhat semi- 

 circvdar notch, the inner apex of which is slightly elevated, and the 

 second, third, and fourth segments are depressed in the middle 

 of the hinder margin, the third and fourth segments having also on 

 each side of the extremity of the depression a very minute elevation. 



Ealkirk, Northumb., Dur., Cumb., Wicken and Horning Eens, 

 Preston, Eepton, Southend, "Weston, and London district. Not un- 

 common. 



PLANTAEis, Erichson. Of the same size and appearance as 

 binotatus, from which it may be readily distinguished by its rufo- 

 testaceous tarsi, palpi, and antennae (in which the club is pitchy, and 

 the joints are more robust). In punctuation it resembles puhescens, 

 from which the above characters also separate it. It is, besides, rather 

 more shining and depressed than either of these species, and its abdo- 

 men is more attenuate at the apex.
