In the more typical examples (not the most numerous of the large series examined) 

 the thorax has two (sometimes united) dorsal vitta? and the elytra a broad postmedian 

 fascia (margined with cinereous spots) dark brown ; but the dark pigment sometimes 

 expands into a large central patch common to both elytra, or diminishes to two bands 

 of dusky spots ; or the dark spots are absent and their companion cinereous spots only 

 present. The majority of the specimens are, however, uniform greyish-ochreous. The 

 elytra have a few very short stiff bristles arranged in rows ; the under surface is covered 

 with small oval greyish scales implanted at short distances from each other,
