B. Elytra ivith an ochreous vitta, epipleiii'se black. 



5. S. elongata (Fab.), Syst. El. i. 500. 



Elongate oval, oeneous, head and thorax punctate shining, the 

 latter broader in front; elytra obsoletely punctate, with a narrow 

 dorsal vitta ochreous, not reaching the apex. L. .16. Atlantic 

 region. 



6. S. miles (Lee), Pac. R. Rep., p. 68. 



Yeiy like S- frontalis, but head sparingly punctate ; thorax al- 

 most smooth ; legs pale, head and thorax ochreous, this with the 

 sides black; elytra as in S. e?o;?^a/a, but with deeper punctures 

 by the scutellum and along the suture. L. .15. California. 



S. ligata (Lee.) is a mature specimen, in which the thorax is 

 much darker and has numerous larger punctures visible. 



S. ochracea (Lee.) is entirely immature, but may belong here 

 also. 



7. S. marginalis (HI.), Mag., ri. 160; ohlonga (Lee), Ann. Lye, i. 173. 

 Entirely ochreous, sides of thorax and elytra and el^'tral epi- 



pleura? black ; thorax and elytra rather closely punctate, alutace- 

 ous; thorax short, sides nearly straight ; posterior angles promi- 

 nent. L. .14-.16. Southern and Western States. 



The eyes are nearer together in this species, so that the frontal 

 space is narrower; the elytral epipleurse are frequently almost 

 pale ; the thorax is often transversely impressed across the base. 



C Elytra ivith a dorsal vitta, margin, and epijileurse pale. 



8. S. blanda, Mels. Pr. Acad., iii. 164. 



Ochreous, under side black; thorax short, closely reserablino- 

 that of S'. miles, from which it differs in having the elytral epi- 

 pleurae pale. L. .14-.16. Atlantic region. New Mexico. 



S. hitseniata (Lee.) appears to me to be founded on unusually 

 large and dark individuals of this species. 



Orthaltica, g. n. 

 Very distinct by the long antenna?, parallel form, short tarsi, 

 and irregularly' striate eljtra; the antennjE are closely approxi- 

 mate, the frontal tubercles very distinct ; the prosternum rather 

 broad, anterior coxae distant. 



1. 0. copalina (Fabr.), Sj-st. El., i. 466. Forticornis, 111. Mag., vi. 3. 



Parallel, subelongate, shining, pitchy ; head, thorax, antenna?, 

 and legs red ; head closely and deeply punctate ; thorax trans-
