COLEOPTERA. 19 



punctured and channeled ; upon each side of the pronotum near the base 

 there is a shallow impression ; canaliculation nearly obsolete, commencing 

 at the middle and not attaining the base; anterior and posterior margins 

 arcuate. Elytra at base narrower than the head ; together broadly emargi- 

 nate at the base and apex : sides feebly arcuate and slightly divergent poste- 

 riorly ; suture equal in length to the pronotum; surface very deeply and 

 closely punctured and channeled ; near the base of each elytron there is a 

 slight elevation; orange-yellow spots small and nearly circular, very close 

 to the outer margins, ami just behind the middle. Abdominal segments 

 decreasing very gradually in width posteriorly; border distinct on the first 

 four, very narrow on the fifth and sixth ; punctures rather fine and distant, 

 becoming very fine posteriorly; transverse carinae well developed, tricuspid, 

 intervals distinctly sinuate. Legs rather long, very slender, pale brownish- 

 testaceous ; femora darker in the outer half; tarsi slender; first joint of 

 posterior rather longer than the next three together. Coxae darker than the 

 femora. Under surface piceous-black, feebly punctate, shining. 



Male. — Fourth ventral segment very feebly emarginate in its middle two- 

 fifths, surface bordering emargination deeply impressed, border of impressed 

 area densely clothed with long setae ; fifth segment emarginate in its middle 

 third, emargination evenly rounded, four times as wide as deep, contiguous 

 surface broadly channeled, border of channel-like impression ciliated ; sixth 

 segment roundly emarginate in its middle third at apex, width of emargina- 

 tion but slightly exceeding its depth ; seventh segment emarginate at apex. 



Female. — Unknown. 



Length 4.0 mm. 



Georgia, 1. 



A very distinct species in every respect. 



7. S. Mleiltigatlis n. sp. — Form moderately robust. Pubescence of 

 entire body very short, fine, and setiform, extremely sparse. Head well 

 developed, twice as wide as long ; interocular surface well excavated, three 

 times as wide as the eye, deeply and closely punctured ; longitudinal eleva- 

 tion moderately prominent ; antennae much longer than the width of head, 

 slender, very deep fusco-piceous, darker toward tip, club well developed ; 

 third joint slightly more than one-third as long again as the fourth, fourth 

 and fifth almost equal, sixth and seventh nearly equal, shorter, tenth and 

 eleventh equal in length, each much longer than the ninth ; ocular lines 

 meeting at about one and one-half lengths in advance; maxillary palpi pale 

 flavo-testaceous throughout. Prothorax widest at the middle, where it is 

 four-fifths as wide as the head and slightly narrower than long ; sides from 

 mid-section gradually convergent and sinuate ; surface deeply, closely, and 

 rather evenly punctured ; a narrow and deep canaliculation begins slightly 

 behind the middle, and extends posteriorly a distance equal to about one- 

 fifth the length ; posterior margin nearly straight. Elytra at base as wide 

 as the head, sides rather strongly divergent, arcuate; suture about one. tilth 

 as long again as the pronotum ; humeral angles rather acute ; at the middle 

 of the base ot each there is a. marked elevation which disappears at a very 

 short distance posteriorly; just behind the middle and situated slightly
