88. S. j ej UllUS n. sp. — Form robust. Pubescence rather abundant, 

 semi-erect, cinereous, moderate in length. Head small, scarcely twice as 

 wide as long; interocular surface flat, a little more than twice as wide as the 

 eye, finely and rather closely punctate ; sulcations shallow, but distinct ; 

 ocular lines meeting at about two lengths in advance ; antennae very short 

 and robust, scarcely as long as the width of head, dark fuscous, sparingly 

 setose, club distinct ; joints three to five equal in length, six and seven equal, 

 last two equal, very large, sub-globular, ninth very much smaller ; maxillary 

 palpi slender, piceous-black, base of first joint slightly paler. Prothorax 

 widest just before the middle, where it is four-fifths as wide as the head ; 

 sides thence convergent slightly posteriorly, sinuate ; length slightly greater 

 than width ; anterior and posterior margins equal in length and equally 

 arcuate ; surface rather evenly convex ; deeply, rather finely and irregularly 

 punctate ; interspaces moderately shining ; a long, narrow and equal medial 

 canaliculation extends to within a very short distance of either margin. 

 Elytra at base perceptibly wider than the head ; sides divergent posteriorly 

 and arcuate ; together broadly and feebly emarginate behind ; suture one- 

 fifth as long again as the pronotum ; surface of eacli slightly swollen near 

 the inner basal angles ; deeply and rather unevenly punctate ; punctures 

 impressed, interspaces generally wider than the punctures, shining. Abdo- 

 minal segments decreasing moderately and evenly in width posteriorly, first 

 narrower than the elytra ; very finely and rather closely punctulate ; surface 

 moderately shining ; transverse carinae 4-cuspid, cusps having the points 

 expanded, intervals strongly sinuate. Legs moderate, dark piceous-black, 

 tarsi very slightly paler ; first joint of the posterior about twice as long as 

 the second, second slightly longer than the third. Under surface of the 

 abdomen much more coarsely and distantly punctulate than the upper, 

 having the surface more highly polished. 



Male. — Posterior edge of the fifth ventral segment very broadly and feebly 

 bilobed ; sixth very broadly and strongly sinuate at apex, depth of sinus 

 equal to one-fifth its width ; seventh segment deeply emarginate at apex. 



Female. — Unknown. 



Length 3.0 mm.

SO. S. viimullis n. sp. — Form moderately robust. Pubescence long, 

 semi-erect, fine, rather abundant, piceo-cinereous on the elytra and abdomen, 

 shorter and erect on the head and prothorax. Head moderate, twice as wide 

 as long ; interocular surface flat, more than twice as wide as the eye ; equally 

 trilobed by the scarcely perceptible sulcations ; intermediate surface evenly 

 and feebly convex ; punctu-res closely crowded, small, polygonal, and some- 

 times coalescent ; antennae much longer than the width of head, slender, 

 coarsely setose, basal joint black, remainder piceous-black, club not con- 

 spicuous ; third joint one-fourth as long again as the fourth, fourth slightly 

 longer than the fifth, sixth and seventh of equal length, eighth twice as long 

 as wide, conoidal, joints of club of nearly equal length, increasing in width, 

 ninth conoidal, last ovoidal ; first joint of maxillary palpi piceo-testaceous, 

 base of second same, remainder piceous. Prothorax elongated, widest slightly
