the length of the body, dark towards the tip ; thorax much broadre than 

 long, moderately narrowed towards the front, not one-half as long as the 

 elytra, with M very diffusely marked and with moderately coarse, thickly- 

 placed livid punctures, remainder of surface sparingly punctate, some of 

 the punctures, notably in the yellow side margin, not being coloured with 

 livid, transverse depression very well marked behind, but the depressed 

 area at the end being diffused and not as well marked as in the following 

 species (cyiindricus), sides subangulate ; elytra stout, with very coarse 

 livid punctures, which are confused around the scutel, also in the fourth 

 interval at the base and on the sixth and seventh intervals as far as 

 the convexity — otherwise, arranged in regular rows forming punctate 

 striae, especially deep and well marked at the side and behind, the third 

 and fourth intervals have a tendency to widen where the shield begins — 

 the general appearance is rather regularly punctate striate, tip plain, mar- 

 ginal stria lightly sinuate behind the lobe, which is broad and well 

 developed, with a few marginal punctures in the curve, the forward edge 

 at the base of the elytra is raised in a sharp edge ; body below thickly 

 silvery pubescent, livid with yellowish epimere and pygidium, legs yellow, 

 with usual darker parts in livid, fossa of $ deep, longitudinal shining.

Pachybrachys cylindricus, nov. sp. — Large, cylinder-shaped, finely 

 punctured, shining yellow, with standard brown marks on elytra. Length, 

 3-4^ mm. 



Head with convex front, finely and sparsely punctate, badly defined 

 livid central line, but with vertex spot well marked, eyes distant in both 

 sexes, but most so in $ and very narrowly margined with livid on 

 the upper side, antennae yellow, gradually darker to tip, reaching the hind 

 coxa in ^ , shorter, in 9 . Thorax yellow, very little narrowed in front, 

 smooth, very lightly and finely punctured, transverse impression well 

 marked, with its terminations on each side ending in depressed areas, 

 especially well marked in ? ; M fairly well marked in £ , rather diffuse 

 in female, the ends of sides of M coincide with the depressed areas, 

 sides very slightly curved in £ , subangulate in 9 ; elytra a trifle wider 

 than the thorax, yellow, with coarser livid punctures, and the standard 

 spots which have a tendency to form into transverse bands of brown livid ; 

 the punctuation is confused about the scutel, the third and fifth interval's 

 are pretty well defined, so that the punctures on either side form fairly 

 regular striae, with a well-defined shield in the usual place ; between the 

 fifth and humeral intervals the striae are much broken, as far as the
