visible, the lateral lines on the head and pronotum are well marked, 

 and the deeper markings of the alxlomen are black instead of reddish 

 fuscous.

1888, Stenopelmntus califoniicus Brunner, Verb. Zool.-bot. Gesellsch. Wien,

 tion of the Academy (Cope Coll.). 



Stenopelmatiis fa!«ciatii!« Thomas. 



1875, Steuoijelmatas fasciatus Thomas, Prelim. Rep. U. S. Geol. Surv. Mont., 

 p. 434. 



Two specimens ; Salt Lake City, Utah. Collection of the Academy. 



In the original description of this species Thomas mentioned 

 specimens from Utah, but none have since been obtained, with the 

 exception of the specimens here recorded. 



Stenopeimatus lii$4trio Saussare. 



1859, Renopelmatm histrio Saus., Revue et Magas. de Zool., 2e ser., xi. p. 210. 



Two specimens; San Francisco, Cal.; collected by L. E. Rick- 

 secker. Collection of the Academy (Cope Coll.) 



$<iteiiopelinatiis longispina Brunner. 



1888, Stenopelmatns longiynna Brunner, Verh. Zool.-bot. Gesellscb. Wien, 

 xxxviii, p. 260. 



One specimen ; Texas. Collection of the Academy. 

 The occurrence of this species in Texas was quite unexpected, but 

 the specimen falls quite naturally into Bruuner's species. 



Steiiopeliiiadns pictus Scuddcr. 



1899, Stenopelmaius pictus Scudder, Canad. Ent., xxxi, pp. 114, 116. 



One specimen ; San Franscico, Cal. ; collected by L. E. Rick- 

 secker. Collection of the Academy (Cope Coll.). 



This specimen is topotypic, asScudder's types came from the same 

 locality. 



The character used by Scudder (Canad. Ent., xxxi, p. 144] to 

 separate the genus Stenopelmatas into two sections is apparently very 

 unreliable. The spines on the internal margin of the posterior tibije 

 in the specimens before me (twenty-three in number) present many 

 discrepancies from Scudder's key. In some specimens the number on 

 opposite limbs are not the same, and in a few cases the spines are 

 almost invisible, though the specimens can, by all other characters, 

 be referred to a species normally possessing prominent spines.
