some works which are necessary. These I have reserved to be described 



in a subsequent paper. 



STENOPELMATUS. 



STENOPELMATUS FASCIATUS, Thos. 



Stenopelmatusfasciatus, Thos., U. S. Geol. Sorv. Terr., 1871, 434. 



This species is distinguished by the dark fascia or bands across the 



abdomen, each segment having one band on it. I have heretofore seen 



specimens from Texas, Colorado, Wyoming, Utah, and Southern Idaho, 



to which list of localities may now be added Nevada and Arizona, as shown 



by this collection. 



CEUTHOPHILUS. 



There is one specimen of this genus in the collection of 1872, but it 

 is too badly damaged to determine what species it is. 



UDEOPSYLLA. 

 UDEOPSYLLA NIGRA, Scud. 

 Udeopsylla nigra, Scud., Jour. Bost. Soc. Nat. Hist., vii, 18G2, 443. 



There is one specimen of this species, a female, in the collection of 

 1872. This is the first time I have seen this species ; but Dr. Scudder's 

 description is so exact that I feel no doubt as to the correctness of my 

 identification, although the reddish stripe on the back is wanting. 



DECTICIDES. 



This group is the subject of a paper by Otto Hermann (Verliand. d. 

 Tt.-h. sool.-bot Ges., IS 74), in which he reviews my arrangement as given in 

 my paper published in Geol. Surv. Terr., 1871, 440. 



Although differing from me on some points, yet this author's plan does 

 not vary very materially, so far as the grouping is concerned, from that I 

 have given. But a reference to my paper will show that I considered it 

 as depending too much upon a minor character, and gave it more as a pro- 

 visional arrangement than otherwise. 



Mr. Hermann certainly deserves the thanks of entomologists for disen- 

 tangling and properly limiting the genera of this group. He not only 

 retains both Rhacoclcis and Pterolepis, which 1 considered as synonyms, but 

 also adds some new genera. Having 1 access to the line collection of Dr.
