B. sordUhda resembles the i»i"ecediug', but is decidedly slighter and 

 more obscure. The luiile is almost immaculate, with the lines barely 

 traceable, except on the costa, while the female has the angles of the 

 transverse posterior line better marked, but the violet or bluish shade 

 of the outer portion of the wing decidedly obscure, powdery, altogether 

 more sordid. 



B. toreuta is smoky brown in both sexes, the median lines very slen- 

 der, rivulous, white, fragmentary; the transverse ])osterior marked on 

 the internal margin by a. prominent, oblong, white S]»ot, which distin- 

 guishes the si)ecies at a glance. 



B. nmbralis is a curious form, difCering in the more trigonate [>ri- 

 maries, the outer margin oblique and little arched. The maculation is 

 all obscure, the transverse i)osterior line rigid and a little outwardly 

 oblique, starting just a little beyond the middle of the costa. 



The two species with long palpi are very different. B. cdkiaUs is 

 the largest of all our si)ecies; but is less robust than the male B. inade- 

 fdctdlis. It has the transverse posterior line like B. decejitalis, but is 

 altogether a more jiowdery form with numerous irregular brown trans- 

 verse striga', which give it a distinctive appearance. 



B. citaia is much the smallest of the species and is perhaps nearer to 

 true Hf/pcna than anything heretofore mentioned, excei)t in the i)ropor- 

 tionately small secondaries. It resembles B. iimbraliti in having the 

 apparent transverse posterior line crossing near the middle of the fore- 

 wing. 



An ally of this latter will be found, perhaps, in Enoitria mitographa, 

 Grote. I have seen only one of the types which lacks the wings on one 

 side, and it may not belong here with my present ideas on the genus. 

 I i)refer, therefore, to omit it at present and relegate the species to the 

 genus 111 which it is described until material can be obtained, 



B. anmdaUs also is not represented in the collection betore me, and 

 though I have seen the type, which indicates a good and distinct 

 species, I can not add to the somewhat scant description. 



Bomolocha inciisaliSj Grote, belongs to B Icon eetyptera. 



I have a single male specimen from South .Dakota which indicates a 

 a new species allied to B. deeeptalis^ but this is hardly sufficiently good 

 to form a type. 



ANALYSIS OF THE SPFX'IKS OF F.nMOLOC IIA. 



1. Palpi oblique, moderate in length, exceeding the, head by little more than its 



own length 2. 



I'alpi straight, exceeding the head by the length of head and thorax com- 

 bined 7. 



2. Median lines of jirimaries not reaching the inner margin, uniting inferiorly 



to inclose a contrastingly brown, rhomboid median space manalis. 



Transverse anterior line not reaching the costa; basal space siiperioi'ly brown 



above the transverse anterior line, inferiorly ])ale 3. 



Median lines normal, reach both costa and inner margin 4.
