Remarks. — In shape this species approaches the species of the 

 genus Heikertingerella, being ovate, moderately convex, with a pro- 

 thorax about twice as wide as long and without a basal sulcus of any 

 sort. The species differs from that genus, however, in the less 

 sinuate basal margin of the prothorax, which does not dip down as 

 much over the scutellum, and in the lateral margin, which is very 

 sinuate, even angulate, and with a more distinctive oblique angle 

 anteriorly and a larger tooth basally. The elytra, too, are not as 

 smoothly convex but have a transverse depression below the basal 

 callosity. The terminal joints of the antennae are much more enlarged 

 than in Heikertingerella, and the head has wider interantennal space. 

 The punctation of this and the species below is much coarser than 

 that of any species of Heikertingerella. 



Sidfaya punctatissimaf new series 



Figure 23 



Between 2 and 3 mm. in length, oblong ovate, shining piceous black, 

 pronotum and elytra densely and moderately coarsely punctate, pro- 

 thorax twice as wide as long with prominent obhque angles anteriorly 

 and somewhat angulate lateral margin, elytra with transverse depres- 

 sion below basal callosities, antennae yellowish brown with four 

 terminal joints wider and darker, not extending much below humeri. 



Head with interocular space approximately haK width of head, 

 occiput rounded, impunctate, pohshed, a groove with several punctures 

 along it from eye to frontal tubercles, frontal tubercles small and 

 clearly cut, a broad and somewhat produced interantennal area widen- 

 ing below, lower front slightly concave. Antennae not extending far 

 below humeri, joints one and two swollen, joints three to six slender 

 and subequal, joints seven to eleven giadually wider, but not much 

 longer, hairier and darker. Prothorax twice as wide as long with 

 prominent oblique anterior angles having tooth at lower end, at mid- 

 point margin sharply rounded, at base a small tooth, disc not very 

 convex, shiny piceous black with numerous moderately coarse and 

 deep punctures, not too closely placed in all parts. Scutellum dark 

 and shiny. Elytra sHghtly wider in apical half, moderately convex, 

 with prominent basal callosities and transverse depression below them, 

 surface shining black, coarsely and almost contiguously punctate, 

 epipleura vanishing at apical curve. Body beneath entirely dark, 

 prosternum extending down widely between anterior coxae, hind 

 femora enlarged, hind tibiae not channelled, but rounded, with spur 

 at apex, claws appendiculate. Length 2.8 mm.; width 1.4 mm.
