NORTH AMERICAN (WLEOPTERA. 99 



1'^. — Elytra relatively coarsely punctured, black with a spot of variable si/,e nearly 



central on each elytron, rarely absent piiiictHtii$$. 



Elytra very indistinctly punctate, almost entirely reddisli yellow, base and 

 suture alone dark voiiiferaruni. 



S. pallens Lee. — Rather Ijroadly (jval, niaruin slij;htly interrupted, convex, 

 rufo-testaceous above, beneath black, except the last three segments of abdomen, 

 legs pale. Head very sparsely i)unctate. Thorax narrower in front, sides ar- 

 cuate, surface finely evenly ])unctute, basal marginal line distinct. P^lytra mod- 

 erately, finely and not deeply punctate ; i)rosternuni punctate, the elevated lines 

 short, posterior; nietastei'num at sides coarsely, closely punctate, mesocoxal line 

 arcuate, joining the suture near the front. Abdomen coar.sely and closely punc- 

 tate, the metacoxal line forming a complete arc very nearly as long as the first 

 segment. Length .0(5 — .08 inch. ; L5 — 2 mm. 



The ubdonieii lias five segments only. This species resembles 

 Fhelimi, which, however, has an inconi].)lete metacoxal arc. The 

 first itvvo ventral .segments and the middle of the third are black, 

 the rest of the abdomen yellow. 



Hab. — California, San Francisco, Alameda, Los Angeles, Yuma. 

 American P^ork Canon, Utah, Pinal Mountains, Ariz. 



S. cinctlis Lee. — Broadly oval, convex, outliue continuous, beneath piceous, 

 above in great part reddish yellow, the thorax with a basal piceous .s])ot, which 

 continues on the elytra gradually narrowing, reaching more than three-fourths 

 the length of the suture. Head not densely punctate. Thorax narrower in front, 

 sides feebly arcuate, basal marginal line distinct, surface finely and eipially punc- 

 tate. Elytra much more coarsely and deeply jjunctured than the thorax ; pro- 

 sternum punctate, the elevated lines convergent to the fi-ont ; metasteruum at 

 sides coarsely and closely punctate, the mesocoxal line arcuate, joining the suture 

 near the front. AWomen closely punctate, the metacoxal line entire not quite 

 reaching the margin of the segment, the outer end reaching the anterior angle 

 of the segment ; femora piceous, tibia? and tarsi paler. Length .08 inch, slightly 

 more or less ; 2 mm. PI. II, fig. 5. 



Under the above name sutarulia \\ Lee. { Le (Jontei Cr.) is included. 

 These two species were described from uniques, and the slight differ- 

 ences indicated vanish in a small series. As a rtile, howevei', the 

 California specimens are somewhat more densely jjunctured, but not 

 less coarsely as stated by LeConte. 



In nearly all the specimens examined there is a short, narrow, 

 piceous s})ace at the side nuirgin of the elytra slightly behind the 

 middle. Thirteen specimens examined. 



The species is very close to Loewii and fioraiis, and the differences 

 noted by LeConte are as to the first of the most evanescent character, 

 and as to the second refer rather to a variety mentioned by Mulsant. 



Hab. — New Orleans, Texas, westward to California, Yuma to 

 Los Angeles.
