are four or five, at first sight very diflerent, forms, wliicli arc, 

 however, connected hy intergrades. Head greyish witli or 

 without brown speckles. Lower lobe of the eyes small, 

 sub(jua(lrate, hardly as long as the gena. Antenuaj about 

 as long as the body, more or less distinctly annulate M'ith 

 pale yellow at base and apex of joints 3-10, and speckled 

 with brown or fuscous. Protborax transverse, truncate at 

 base and apex, evenly convex above and finely punctured, 

 with the sides arcuate, greyish or brownish without distinct 

 markings. Scutellum always black or fuscous with narrow 

 pale margins. Elytra rather short, truncate at base, and 

 broader than the thorax, subcylindrical to beyond middle, 

 thence narrowed and strongly sloping to the apex, each with 

 the apex rounded and unarmed, somewhat flattened above 

 from base to middle and very slightly swollen at the base on 

 each side of the scutellum, and with a nearly obsolete discal 

 costain the middle; rather strongly punctate, the punctures 

 nearly arranged in rows, stronger and deeper on the sides 

 of the disc, some of the punctures being distinctly larger 

 than others. According to colour and markings of the 

 elytra the following varieties may be distinguished : — 



a. The typical form (PI. XIII. fig. 8). — Ground-colour dark 



greyish-brown, a broad yellowish-white stripe from the 

 shoulders to the suture, forming then a broad sutural 

 band, which is widened posteriorly to an irregular pale 

 patch at the beginning of the posterior declivity. The 

 ground-colour consequently occupies the scutellar 

 region, the whole sides (being much broader in the 

 middle), and the apex of the elytra. 



b. Ab. suturalis, nov. — Elytra above from base to the 



posterior declivity with a very broad greyish-white 

 sutural band, somewhat narrowed at the middle. 

 Differs from the typical form by having the ground- 

 colour of the sides produced to the shoulders, but not 

 occupying the scutellar region. 



c. Ab. abscissa, nov. — The dark colour of the sides of the 



elytra more or less strongly widened above, often 

 reaching the suture a little behind the middle and 

 separating the anterior part of the pale sutural band 

 from the posterior patch, which is nearly always 

 extended over the whole declivity to the apex. 



d. Ab. niinusculuy nov. — Differs from the typical form only 



by having the whole apical declivity as pale as the 

 sutural baud. Only a very small specimen, length 

 ■i mm.
