most prominent is usually the shield, though some other spots towards the 

 sides are of the same size, but not so prominent at the first glance ; the 

 marginal stria is very slightly curved around the humerus and lightly 

 sinuate behind, the lobe is hardly noticeable, and almost wholly occupied 

 by a row of punctures, body below black, legs yellow, with dark rings on 

 the thighs and clouds on the shanks and tarsi.

In well marked examples the general appearance is yellow, caused by 

 the numerous raised yellow spots on the elytra ; then specimens occur 

 where the yellow areas are few, and it approaches close to characteristicus. 

 In general appearance it resembles some forms of bajuhts, Suff. 



Pachybrachys proximus, nov. sp. — Medium sized, or rather large, 

 stout, black, with yellow spotting, always with a small, round shield spot. 

 Thorax very finely and elytra coarsely punctured. Length, 2)^ mm. 



Head convex, thickly punctured, entirely black, except for two 

 triangular spots between the eyes, a large, rather irregular quadrate spot 

 between the antenna; and the labrum yellow, eyes very distant, antenna; 

 red at base, and becoming dark brown after about the middle, and reaching 

 to or a trifle beyond the middle of the abdomen in the o* . not s0 lon g ni 

 9 j thorax more than half the length of the elytra, tubularly constricted in 

 front, depressed behind and humped about the middle, finely and evenly 

 punctured, black, except the anterior angles, margin narrowly, and a 

 narrow median line to beyond the middle and a small spot on each side 

 at the base yellow, the median line is smooth, antescutellar impression 

 well marked, lateral edge just barely bowed in £ , angulate in 9, hind 

 angles obtuse ; elytra somewhat compressed behind the shoulders, yellow, 

 with the exterior standard spots suffused so that the two anterior ones are 

 wholly joined, and they connect on the margin with the posterior spot 

 (which otherwise is free), the interior spots are confused together longi- 

 tudinally, and also spread sideways back of the shoulders and before the 

 convexity to meet the two anterior exterior spots, having a well-marked 

 shield, the keel and spots off from it yellow ; the tip and around the hind 

 exterior standard spot is yellow, the punctuation is coarser than the thorax, 

 and everywhere diffuse, even to the tips of the elytra, the third, fifth and 

 humeral intervals are traceable for part of their length, the yellow area at 

 the side is elevated in fragments of ridges, marginal stria very lightly 

 curved at the humerus and almost straight behind, lobe small, black, with
